CROSS-REFERENCE TO RELATED APPLICATION(S)

This application claims the benefit under 35 U.S.C. .sctn. 119(a) of Korean patent application assigned Serial number 10-2016-0162161, filed on Nov. 30, 2016 in the Korean Intellectual Property Office, the entire disclosure of which is hereby incorporated herein by reference.

FIELD

The present disclosure relates to a method of generating a haptic signal(s), which a user is able to sense, and/or an electronic device for generating a haptic signal(s).

BACKGROUND

Thanks to the increase in the resolution and the operating speed of an electronic device and the improvement of the performance of a graphic processing device, a device outputting virtual reality or a 3-dimensional stereoscopic image, which only a large-size device drives, has been miniaturized and lightened through a smart glass, a head mount device (hereinafter is referred to as a “HMD”), or the like.

For example, an HMD may be mounted on a user’s head and may provide the effect of displaying a large screen in front of the user’s eyes (e.g., the user’s gaze). The HMD may be used to output a stereoscopic image. An augmented reality (AR) service or a virtual reality (VR) service using the HMD or a smartphone has been developed.

In addition, an electronic device may provide the user with haptic effects (or tangible effects) (e.g., vibration, motion, and the like) as well as visual effects and auditory effects, thereby improving the sense of presence.

SUMMARY

A conventional haptic device (or a device of tangible style) (e.g., HMD) may output a haptic effect (e.g., vibration generated depending on a specified timing signal) of a simple type when outputting a stereoscopic image. In this case, since the user feels a simple vibration, the user does not feel the sense of presence by various senses.

In accordance with an example aspect of the present disclosure, an electronic device includes a memory, a communication interface (including communication interface circuitry) capable of performing communication, and a processor electrically connected to the memory and the communication interface. The processor is configured: to extract a first audio signal to be output through a speaker, based at least on audio data received from an external electronic device and/or stored in the memory, to generate a second audio signal obtained by removing the first audio signal from the audio data, and to generate a haptic signal for outputting a haptic effect, based at least on the second audio signal.

Other aspects, advantages, and salient features of the disclosure will become apparent to those skilled in the art from the following detailed description, which, taken in conjunction with the annexed drawings, discloses various embodiments of the present disclosure.

According to various example embodiments of the present disclosure, a haptic signal producing method and/or an electronic device supporting the same may produce a haptic signal(s) based at least on a signal (e.g., a wind noise) that has been removed as a noise signal.

According to various example embodiments of the present disclosure, a haptic signal producing method and an electronic device supporting the same may produce a haptic signal by reflecting various features such as the intensity, the frequency, or the like of a wind noise, and then may provide the user with a haptic effect of various forms. Accordingly, the user feels the sense of presence at a point in time when the user captures an image by using a camera or a camcorder, when the user admires the image.

According to various embodiments of the present disclosure, a haptic signal producing method and an electronic device supporting the same may produce and transmit a haptic signal, which allows a user to feel the sense of presence, by using a circuit executing an existing function to reduce a wind noise.

FIG. 3 is a flowchart illustrating a haptic signal producing method, according to various example embodiments. The haptic signal producing method of FIG. 3 may be performed by one or more of the camera device 110, the first electronic device 120, the server 130, and/or the haptic device 150 in FIG. 1.

Referring to FIG. 3, in operation 310, the processor(s) (e.g., AP or MCU) of an electronic device (e.g., one or more of the camera device 110, the first electronic device 120, the server 130, and/or the haptic device 150 in FIG. 1) may extract a first audio signal to be output through a speaker, based on audio data that is received from an external electronic device and/or stored in a memory.

Additional information about a method for generating the haptic signal based on the second audio signal will be given with reference to FIGS. 4 to 9.

FIG. 4 illustrates an electronic device 401, according to various embodiments. An electronic device 401 may be one of the camera device 110, the first electronic device 120, the server 130, and the haptic device 150 in FIG. 1.

Referring to FIG. 4, the electronic device 401 may receive video data, audio data, and motion data from the camera device 110. The video data, the audio data, and the motion data may be collected through the camera device 110 in FIG. 1.

The electronic device 401 may include an audio processor 410, an audio rendering unit 415, a video processor 420, a video rendering unit 425, a motion processor 430, a haptic information generating unit 440, and a haptic rendering unit 445. The elements of the electronic device 401 may be separated depending upon function. However, embodiments of the present disclosure are not so limited. For example, the operations of the audio processor 410, the video processor 420, the motion processor 430, and/or the haptic information generating unit 440 may be performed by one processor (e.g., AP or MCU) in an example embodiment. In another example, the operations of audio processor 410, video processor 420, and motion processor 430 may be performed by one processor. In another example, the operation of audio processor 410 and video processor 420 may be performed by a single processor. In another example, the operations of audio processor 410 and motion processor 430 may be performed by a single processor. Haptic rendering unit 445 and/or haptic information generator 440 may also be part of any of the aforesaid processors.

The audio processor 410 may receive and process the audio data. The audio data may be collected through the camera device 110 of FIG. 1 together with the video data or may be data recorded independently of the video data. The audio processor 410 may generate a first audio signal, which is to be transmitted to the audio rendering unit 415 through signal processing (e.g., noise cancellation, microphone array processing, gain control, DOA detection, compression, or the like) assigned to the audio data. The first audio signal may be a noise canceling signal obtained by removing noise data (e.g., a specific frequency component) from the input audio data. The first audio signal may be a signal for generating a sound output to the user’s ears through a speaker.

According to various example embodiments, the audio processor 410 may extract a second audio signal (e.g., a noise, a wind noise, an ambient noise, or the like) obtained by removing the first audio signal (e.g., voice (a person’s voice), a sound, the source of which is the closest to a microphone) from the input audio data. The audio processor 410 may transmit the second audio signal (audio feature) to the haptic information generating unit 440. For example, the second audio signal may be a wind noise extracted from the audio data. Additional information about the second audio signal generated by the audio processor 410 may be given with reference to FIG. 5.

The audio rendering unit 415 may receive the first audio signal from the audio processor 410. The audio rendering unit 415 may convert the first audio signal to a sound (e.g., 5.1 ch signal or 7.1 ch signal) that allows the user to feel the three-dimensional spatial sensation and may output the sound through the speaker.

The video processor 420 may process the input video data so as to output the processed data to a display. The video processor 420 may provide the processed data to the video rendering unit 425. In various embodiments, the video processor 420 may extract feature information (visual feature) from the input video data and may transmit the extracted feature information to the haptic information generating unit 440.

According to various example embodiments, the video processor 420 may transform a stereoscopic image (e.g., rotation transformation, distortion transformation, or the like) or may reduce the shake of the stereoscopic image, by reflecting information (e.g., camera pose, trajectory information, or the like) processed by the motion processor 430.

The video rendering unit 425 may render a three-dimensional stereoscopic image based on the video data processed by the video processor 420. For example, the video rendering unit 425 may form a virtual three-dimensional space associated with an area at which the user looks through a HMD, and a periphery of the corresponding area.

The motion processor 430 may calculate camera pose information, trajectory information, and/or motion event information based on the input motion data. For example, the motion processor 430 may calculate the camera pose or the translation (e.g., transposition and/or transformation) of the camera device 110, based on the input motion data (e.g., data collected by GPS, gyroscopes, accelerometers, and/or magnetic field sensors).

The motion processor 430 may calculate trajectory information (or movement trajectory information) of the user based on translation information. The trajectory information may include information about a movement direction, a speed, or the like at a point of a specific time interval.

The motion processor 430 may transmit the camera pose information and/or the trajectory information to the haptic information generating unit 440. The haptic information generating unit 440 may determine and/or change an attribute of a haptic event based on the transmitted information. For example, the haptic information generating unit 440 may determine an output direction of a haptic event (or a haptic effect) generating a wind, based on the trajectory information.

According to various example embodiments, the motion processor 430 may detect a motion event (e.g., a collision event, a shake, or the like) based on the motion data. The motion processor 430 may determine whether the motion event occurs, by calculating how much the motion data coincides with pre-stored motion pattern information. The haptic information generating unit 440 may determine or change the attribute of the haptic event based on the determined motion event.

The haptic information generating unit 440 may generate the haptic information based on the second audio signal and feature information of an image, camera pose information, trajectory information, or motion event information. The haptic information may include information about the time information (occurrence time, occurrence timing, duration, or the like), type (e.g., vibration, shake, or compression/decompression), intensity, direction, or the like of the haptic effect.

According to various example embodiments, the haptic information generating unit 440 may receive the audio data from the audio processor 410 and may reflect the audio data to the generation of the haptic information.

According to various example embodiments, the haptic information generating unit 440 may determine the attribute of the haptic information based on the second audio signal (e.g., a wind noise signal) received from the audio processor 410. For example, the haptic information generating unit 440 may determine a type (e.g., a sound when the window of a vehicle is opened during driving, a breeze, a sound generated according to high-speed movement, a skiing sound, a sound generated when the user boards a ship, or the like) of the wind noise, based on the acoustic feature (spectral characteristic, cepstral characteristic, sound pressure level (SPL), periodicity, or the like) of the wind noise. The haptic information generating unit 440 may determine the attribute (e.g., haptic pattern) of the haptic event based on a type of the wind noise. Additional information about an operation of the haptic information generating unit 440 may be given with reference to FIG. 6.

The haptic rendering unit 445 may generate a haptic signal to be transmitted to the haptic device 150, based on the haptic information generated by the haptic information generating unit 440. The haptic rendering unit 445 may generate a haptic signal(s), which is to be played by haptic device(s), based on the attribute(s) of the haptic device(s) (e.g., a wind generator, a vibrator, and an inertial device) to be connected to the generated haptic information. For example, when generating the haptic signal, the haptic rendering unit 445 may use pose information of the haptic device 150 (in the case where there is direction information in the haptic event). Additional information about the haptic rendering unit 445 may be given with reference to FIG. 7.

FIG. 5 is a flowchart illustrating an operation of an audio processor, according to various example embodiments.

Referring to FIG. 5, in operation 510, the audio processor 410 may segment input audio data at specified intervals. Each of the segmented pieces of audio data (hereinafter referred to as an “audio frame”) may be at least partly overlapped in time. For example, the length of the audio frame may be 10 msec, and an overlapping section may be 5 msec.

In operation 515, the audio processor 410 may perform Fourier transform on each audio frame to convert the audio frame to a frequency signal. Each audio frame may be expressed as magnitude information and phase information of the frequency signal.

In operation 520, the audio processor 410 may extract background noise feature information based on a statistical feature of pieces of magnitude information corresponding to another audio frame different from the current audio frame. For example, the background noise feature information may be a signal to noise ratio (SNR) for each frequency.

In operation 530, the audio processor 410 may determine a section, in which there is a wind noise, based on the statistical feature of pieces of magnitude information corresponding to another audio frame different from the current audio frame.

In operation 535, the audio processor 410 may extract wind noise feature information about the section in which there is a wind noise. For example, the wind noise feature information may become the SNR for each frequency. Herein, noise N of the SNR may be the wind noise.

According to various example embodiments, the audio processor 410 may determine a frequency feature of the wind noise based on the wind noise feature information. For example, in the case where the wind noise feature information is the SNR for each frequency, the frequency feature of the wind noise may be determined by using the SNR for each frequency and the magnitude information.

According to various example embodiments, the audio processor 410 may generate a feature value such as cepstrum, a spectral slope, or the like through additional processing of the frequency feature of the wind noise. The audio processor 410 may determine a type of the wind noise based on the feature value.

According to various example embodiments, the background noise and the wind noise may be processed together without any distinction. The background noise and the wind noise may be processed as a single noise. The sound feature obtained by combining the background noise and the wind noise may be used to generate the haptic information. In this case, the audio processor 410 may generate a feature value such as Mel-frequency cepstral coefficients (MFCC), cepstrum, or the like with regard to a sound obtained by combining the background noise and the wind noise. The haptic information may be generated based on the feature value.

In operation 540, the audio processor 410 may calculate the filter gain of a frequency area, to be used to remove a noise for example, based at least on the calculated background noise feature information and the calculated wind noise feature information.

In operation 545, the audio processor 410 may apply the calculated filter gain to the audio data.

In operation 550, the audio processor 410 may obtain first audio data, in which the noise is removed, by applying inverse Fourier transform or the like. The first audio signal may be obtained through overlap-add.

FIG. 6 illustrates a configuration of a haptic information generating unit 440, including haptic information generating circuitry, according to various example embodiments.

Referring to FIG. 6, the haptic information generating unit 440 may determine the attribute(s) of a haptic event based on a feature value(s) (e.g., acoustic feature) of a second audio signal (e.g., a noise signal). The haptic event may be a pre-defined signal pattern that allows the haptic effect to occur through the haptic device 150. The haptic event may be defined or set in the various forms.

A second audio signal may be a signal obtained by removing a first audio signal (e.g., a person’s voice, a sound having a specified pattern, a sound heard most loudly by a microphone, a sound analyzed as being generated closest to a microphone, or the like), which is to be output through a speaker, from audio data that is received from an external electronic device or is stored in a memory. The second audio signal may include a background sound, a wind sound, or the like that is classified as a noise signal.

Haptic attribute information may be information for setting a type, a duration (start time, end time), a persistence mode (intensity increase, intensity decrease), or the like of a haptic effect (e.g., an effect to generate vibration, inertia, shake, or the like).

According to various example embodiments, the haptic information generating unit 440 may include a feature calculating unit 441 and an attribute calculating unit 442. If the second audio signal (e.g., a noise signal) is detected, the feature calculating unit 441 may extract an acoustic feature value of a noise.

In an example embodiment, the feature calculating unit 441 may segment the second audio signal at a preset time period to generate a plurality of audio frames. Each of a plurality of audio frames may have a section in which each of the plurality of audio frames overlaps another audio frame of a previous time period or a later time period. For example, the N-th audio frame may have a length of 10 ms, may have a section (the same data section) of 5 ms in which the N-th audio frame overlaps the (N-1)-th audio frame, and may have a section of 5 ms in which the N-th audio frame overlaps the (N+1)-th audio frame.

In an example embodiment, the feature calculating unit 441 may measure SPL associated with each of the audio frames. The attribute calculating unit 442 may determine the intensity of a haptic event corresponding to the measured SPL.

In an example embodiment, the feature calculating unit 441 may calculate a feature value (e.g., MFCC, a spectral slope, or the like) associated with each of a plurality of audio frames. For example, the feature calculating unit 441 may perform Fourier transform on a plurality of audio frames and may calculate a power spectrum by using a filter bank of Mel-scale. The feature calculating unit 441 may calculate a log value associated with the power spectrum of each Mel-scale, may perform discrete cosine transform, and may calculate the MFCC.

In an example embodiment, the feature calculating unit 441 may detect an interaural time difference (ITD) and/or an interaural level difference (ILD) of a second audio signal collected through a microphone array. The attribute calculating unit 442 may calculate the direction of a wind by using the detected ITD and/or ILD.

The attribute calculating unit 442 may determine a type of a noise based on the feature value calculated by the feature calculating unit 441 and may assign a haptic device type to be output based on the type of the noise.

For example, a type of a wind noise may include arbitrary various types of sounds such as a sound when the window of a vehicle is opened during driving, a breeze, a sound according to high-speed movement, and a sound caused by rapidly changing a movement direction, and the like. The sound when the window of the vehicle is opened during driving and the breeze may be assigned to the haptic device 150 including a wind generator, and the sound due to fast movement or the change of direction may be assigned to the haptic device 150 such as a Galvanic stimulator that generates an inertia effect.

The attribute calculating unit 442 may determine a type of a haptic event and/or a pattern of a haptic effect by using an extracted feature value. For example, if variance of the MFCC is greater than a preset value, the attribute calculating unit 442 may set a change value of a vibration according to the haptic effect to be relatively great. On the other hand, if the variance of the MFCC is less than a preset value, the attribute calculating unit 442 may set a change value of a vibration according to the haptic effect to be relatively small.

According to various example embodiments, the attribute calculating unit 442 may calculate direction information of an input microphone based on information of a motion sensor (e.g., GPS, acceleration sensor, a gyro sensor, a geomagnetic sensor, a magnetic sensor, or the like). For example, the attribute calculating unit 442 may determine the direction of a haptic event based on the calculated direction information (camera pose) of the microphone and the calculated direction of the wind noise.

FIG. 7 illustrates a haptic rendering unit 445, including haptic rendering circuitry, according to various example embodiments.

Referring to FIG. 7, the haptic rendering unit 445 may generate a haptic signal, which is to be played by one or more of the haptic device(s) 150, based on the generated haptic attribute information. The haptic rendering unit 445 may generate a stereoscopic haptic signal for driving the haptic device 150, based on the haptic attribute information. For example, in the case where a haptic effect output by the haptic device 150 is vibration, the haptic signal may include information about a drive start time, drive strength, a change in drive strength, a drive end time or the like of the vibrator. For another example, in the case where the haptic device 150 is a chair generating a shake, the haptic attribute information may include information about shake direction, shake strength, duration, or the like.

According to various example embodiments, the haptic information generated by the haptic information generating unit 440 may include information about a type of the haptic event, a haptic generating object, or the like, and may include information about a spatial location associated with the haptic event or the haptic generating object. The haptic attribute information may be input to the haptic rendering unit 445.

The haptic rendering unit 445 may select the haptic event (or a haptic object) to be played or may change the attribute of the haptic event, based at least on the location information of the haptic device 150 (e.g., HMD).

For example, in the case where the location information of the HMD is in a state ((latitude, longitude, height, orientation .theta., orientation .phi.)=(37.degree., 127.degree.0’0.00000”, 0, 0.degree., 0.degree.)), the intensity of the haptic event having haptic event coordinates (37.degree., 127.degree.0’0.00001”, 0, 0.degree., 0.degree.) may be smaller than the intensity of the haptic event having haptic event coordinates (37.degree., 127.degree.0’0.00002”, 0, 0.degree., 0.degree.).

For example, in the case where the location information of the HMD is in a state ((latitude, longitude, height, orientation .theta., orientation .phi.)=(37.degree., 127.degree.0’0.00000”, 0, 0.degree., 0.degree.)), the haptic event of haptic event coordinates (37.degree., 127.degree.0’0.00000”, 0, 0.degree., 0.degree.) may generate a haptic effect on the right side of a user, and the haptic event of haptic event coordinate (37.degree., 127.degree.0’0.00000”, 0, 90.degree., 0.degree.) may generate the haptic effect in front of the user.

According to various embodiments, the haptic rendering unit 445 may include a priority determining unit 446 and a correction unit 447.

In the case where the number of haptic events is plural, the priority determining unit 446 may assign the priority of each of the haptic events, based on the location information of the haptic device 150 (e.g., HMD).

For example, the priority determining unit 446, including priority determining circuitry, may set a haptic event, which is closest to a point corresponding to the gaze direction (including a HMD pose) of the user (or wearer), from among a plurality of haptic events using the haptic device 150 to the highest priority. The correction unit 447 may set a weight associated with haptic strength, based on the set priority. The haptic event close to the point corresponding to the gaze direction may have a relatively high weight, and the haptic event far away from the point corresponding to the gaze direction may have a relatively low weight. The haptic attribute information may be combined and generated based on the weight.

The correction unit 447, including correction circuitry, may finely adjust the haptic event. The correction unit 447 may correct the haptic attribute information based on the location information of the haptic device 150 (e.g., HMD) and/or the external information received from an external device. The external information may be provided online or offline through a web or various contents providers.

In an example embodiment, the external information may include weather information. The correction unit 447 may correct and/or add the haptic attribute information based on weather information. For example, in the case where it rains on the day of recording, the correction unit 447 may correct vibration haptic strength generated based on a sound to be relatively weak. In the case where the wind blows strongly on the day of recording, the correction unit 447 may correct wind haptic strength generated based on a sound to be relatively strong.

According to an embodiment, while collecting an image, a sound, or motion data by using a camera device, the external information may be generated based on the collected information at the same time. For example, the external information may be information collected at a point in time, when an image is captured, or information collected during operations such as editing, playback, and transmission after capturing the image.

The application 1370 (e.g., the application program 1147), for example, may include at least one application capable of performing functions such as a home 1371, a dialer 1372, an SMS/MMS 1373, an instant message (IM) 1374, a browser 1375, a camera 1376, an alarm 1377, a contact 1378, a voice dial 1379, an e-mail 1380, a calendar 1381, a media player 1382, an album 1383, a clock 1384, health care (e.g., measure an exercise amount or blood sugar), or environmental information provision (e.g., provide air pressure, humidity, or temperature information).

According to an example embodiment of the present disclosure, the application 1370 may include an information exchange application for supporting information exchange between the electronic device (e.g., the electronic device 1101) and an external electronic device (e.g., the first electronic device 1102 or the second external electronic device 1104). The information exchange application may include, for example, a notification relay application for relaying specific information to the external electronic device or a device management application for managing the external electronic device.

For example, the notification relay application may have a function for relaying, to an external electronic device (e.g., the first electronic device 1102 or the second external electronic device 1104), notification information generated in another application (e.g., an SMS/MMS application, an e-mail application, a health care application, an environmental information application, or the like) of the electronic device. Furthermore, the notification relay application may receive notification information from the external electronic device and may provide the received notification information to the user.

The device management application, for example, may manage (e.g., install, delete, or update) at least one function (e.g., turn-on/turn off of the external electronic device itself (or some elements) or the brightness (or resolution) adjustment of a display) of the external electronic device (e.g., the first electronic device 1102 or the second external electronic device 1104) communicating with the electronic device, an application running in the external electronic device, or a service (e.g., a call service, a message service, or the like) provided from the external electronic device.

According to an example embodiment of the present disclosure, the application 1370 may include a specified application (e.g., a healthcare application of a mobile medical device) according to an attribute of the external electronic device (e.g., the first electronic device 1102 or the second external electronic device 1104). The application 1370 may include an application received from an external electronic device (e.g., the first electronic device 1102 or the second external electronic device 1104). The application 1370 may include a preloaded application or a third-party application downloadable from a server. The names of the elements of the program module 1310 illustrated may vary with the type of an operating system.

According to various example embodiments of the present disclosure, at least a part of the program module 1310 may be implemented with software, firmware, hardware, or a combination thereof. At least a part of the program module 1310, for example, may be implemented (e.g., executed) by a processor (e.g., the processor 1210). At least a part of the program module 1310 may include, for example, a module, a program, a routine, sets of instructions, or a process for performing at least one function.

The term “module” used herein may represent, for example, a unit including one of hardware, software and firmware or a combination thereof. The term “module” may be interchangeably used with the terms “unit”, “logic”, “logical block”, “component” and “circuit”. The “module” may be a minimum unit of an integrated component or may be a part thereof. The “module” may be a minimum unit for performing one or more functions or a part thereof. The “module” may be implemented mechanically or electronically. For example, the “module” may include at least one of an application-specific integrated circuit (ASIC) chip, a field-programmable gate array (FPGA), and a programmable-logic device for performing some operations, which are known or will be developed.

At least a part of devices (e.g., modules or functions thereof) or methods (e.g., operations) according to various embodiments of the present disclosure may be implemented as instructions stored in a computer-readable storage medium in the form of a program module. In the case where the instructions are performed by a processor (e.g., the processor 1120), the processor may perform functions corresponding to the instructions. The computer-readable storage medium may be, for example, the memory 1130.

A computer-readable recording medium may include a hard disk, a floppy disk, a magnetic medium (e.g., a magnetic tape), an optical medium (e.g., CD-ROM, digital versatile disc (DVD)), a magneto-optical medium (e.g., a floptical disk), or a hardware device (e.g., a ROM, a RAM, a flash memory, or the like). The program instructions may include machine language codes generated by compilers and high-level language codes that can be executed by computers using interpreters. The above-mentioned hardware device may be configured to be operated as one or more software modules for performing operations of various embodiments of the present disclosure and vice versa.

A module or a program module according to various embodiments of the present disclosure may include at least one of the above-mentioned elements, or some elements may be omitted or other additional elements may be added. Operations performed by the module, the program module or other elements according to various embodiments of the present disclosure may be performed in a sequential, parallel, iterative or heuristic way. Furthermore, some operations may be performed in another order or may be omitted, or other operations may be added.

While the present disclosure has been shown and described with reference to various embodiments thereof, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the present disclosure as defined by the appended claims and their equivalents.
