Intelligent multimodal navigation techniques using motion of a mobile device sensed by a motion sensing device associated with the mobile device

摘要

Motion is used as an input to a program running on a mobile device. The mobile device may require input also from alphanumeric or text input device. The motion can be used for items such as selection from a list, or navigation on the map. The motion can be sensed on image processing the output of the camera, or can be directly determine using an accelerometer. Existing programs can be explicitly modified, in which case the program accepts the motion directly. Alternatively, the modification can be implicit—where the motion is converted to a signal that the program can accept, without modification.
