Haptic feedback using a keyboard device
First Claim
1. A system comprising:
- a first device of a computer, the first device comprising an input device;
a second device of the computer, the second device physically separate from the first device, the second device comprising a keyboard;
a processor configured to receive a first signal from the first device; and
an actuator configured to receive a second signal from the processor, the second signal based on the first signal and configured to cause the actuator to output a haptic effect to the second device.

Abstract
A low-cost haptic feedback keyboard device for providing haptic feedback to a user for enhancing interactions in a displayed environment provided by a computer. The haptic keyboard device can be a keyboard having multiple keys, or can be a wrist rest or other attachment coupled to a keyboard. The device includes a housing that is physically contacted by the user and rests on a support surface. An actuator is coupled to the housing and applies a force to the housing approximately along an axis that is substantially perpendicular to the support surface, where the force is transmitted to the user contacting the housing. In one embodiment, the force is an inertial force that is output by moving an inertial mass. The keyboard device can be used in conjunction with another haptic device, such as a mouse, trackball, or joystick.
