Microsoft Patent | Haptic Feedback System

Patent: Haptic Feedback System

Publication Number: 20190004602

Publication Date: 2019-01-03

Applicants: Microsoft

Abstract

Examples are disclosed that relate to providing haptic feedback. One example provides a haptic feedback system comprising a wearable device configured to be worn by a user, the wearable device including a fluidic channel, a fluid disposed within the fluidic channel, the fluid including an adjustable viscosity, a circuit configured to vary a field within the fluidic channel, and a controller. The controller is configured to receive a first input, and in response to receiving the first input, apply a first field within the channel via the circuit to set the adjustable viscosity of the fluid to a first viscosity, and receive a second input, and in response to receiving the second input, apply a second field within the channel via the circuit to set the adjustable viscosity of the fluid to a second viscosity.

Background

Various devices may be utilized to provide haptic feedback for a computing device. For example, a wearable device may provide haptic feedback in the form of vibration when worn or carried by a user.

Summary

One example provides a haptic feedback system comprising a wearable device configured to be worn by a user, the wearable device including a fluidic channel and a fluid disposed within the fluidic channel, the fluid including an adjustable viscosity. The system further comprises a circuit configured to vary a field within the fluidic channel, and a controller. The controller is configured to receive a first input, in response to receiving the first input, apply a first field within the channel via the circuit to set the adjustable viscosity of the fluid to a first viscosity, receive a second input, and in response to receiving the second input, and apply a second field within the channel via the circuit to set the adjustable viscosity of the fluid to a second viscosity.

This Summary is provided to introduce a selection of concepts in a simplified form that are further described below in the Detailed Description. This Summary is not intended to identify key features or essential features of the claimed subject matter, nor is it intended to be used to limit the scope of the claimed subject matter. Furthermore, the claimed subject matter is not limited to implementations that solve any or all disadvantages noted in any part of this disclosure.
