Modulation of haptic feedback

摘要

The subject disclosure is directed towards a technology by which a device includes one or more haptic feedback mechanisms that may be operated in a controlled manner to output amplitude-controlled vibrations. In one aspect, the vibrations from at least two haptic feedback mechanisms are combined, providing different amplitudes at different device locations. In one aspect, a haptic feedback mechanism outputs vibrations with a one amplitude in one state, and another, different amplitude in at least one other state, as controlled by the controller. The different states may correspond to different weights being driven at different times, and/or different positions of one or more weights.

1. A device, comprising:
a screen; a plurality of haptic feedback mechanisms spaced about the screen at a plurality of locations; and a controller which controllably operates each haptic feedback mechanism of the plurality of haptic feedback mechanisms to output a respective amplitude-controlled vibration at each location of the plurality of locations; wherein at least one of the plurality of haptic feedback mechanisms comprises at least two weights and a motor operated by the controller, wherein the motor is operated by the controller to selectively output vibration at a first amplitude by rotating a first weight in a first state, and at a second amplitude different from the first amplitude by rotating the first weight and a second weight in a second state; and wherein the device comprises an electromechanical mechanism operated by the controller, wherein the electromechanical mechanism is operated to couple the first weight and the second weight to one another for rotating both the first weight and the second weight in the second state.
