Patent ID: 8531398

Claim:
An apparatus comprising: a display device configured to be implemented in a vehicle, wherein the display device is further configured to display, to a user, a cursor relative to one or more objects; a first accelerometer configured to be implemented in the vehicle in which the display device is implemented, wherein the first accelerometer is further configured to, in response to motion of the vehicle, generate a first signal representing an acceleration of the vehicle due to the motion of the vehicle; a second accelerometer configured to be worn by the user while the user is in the vehicle in which the display is implemented, wherein the second accelerometer is further configured to, in response to the motion of the vehicle, generate a second signal representing both i) an acceleration of the user within the vehicle, and ii) the acceleration of the vehicle due to the motion of the vehicle; and a controller configured to based on the acceleration of the vehicle represented by the first signal, isolate i) the acceleration of the user within the vehicle represented in the second signal from ii) the acceleration of the vehicle represented in the second signal, and move the cursor relative to the one or more objects, as displayed by the display device, based on the acceleration of the user within the vehicle represented in the second signal as isolated from the acceleration of the vehicle represented in the second signal.
