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.
