FORCE FEEDBACK SURFACE FOR AN ELECTRONIC DEVICE

摘要

An accessory device having a first and second body is described. The second body may include a force feedback mechanism that responds to an input received at the first body causing a force feedback. The force feedback mechanism includes coils distributed throughout the second body, with each coil configured to receive an electrical current such that each coil provides an external magnetic field to magnetically couple with one or more magnets disposed in the first body, causing the first body to move in a direction toward the second body. The first body may return to its original position when the external magnetic field is no longer applied. In this regard, the movement of the first body defines the force feedback. Also, the first body may include a keyboard or a touch screen functioning with the force feedback mechanism. The accessory device may be used in conjunction with an electronic device.

主权项

1. An accessory device suitable for use with an electronic device, the accessory device comprising:
a first body comprising a touch sensitive layer embedded in the first body and configured to receive a touch input; and a second body separate from the first body and comprising a force feedback mechanism that provides a force feedback at the first body in response to the touch input.
