Acceleration reference devices, cellular communication terminal systems, and methods that sense terminal movement for cursor control

摘要

An acceleration reference device comprises an accelerometer that is configured to generate acceleration information that is indicative of movement of the device; a communication interface that is configured to be communicatively coupled to a proximately located computer; a controller that is configured to generate movement information based on the acceleration information from the accelerometer and to communicate the acceleration information through the communication interface to the proximately located computer. The acceleration reference device cooperates with a cellular communication terminal configured to function as a mouse for the proximately located computer or for itself. Related terminal systems and methods are disclosed for using the device to provide mouse type functions.
