Portable electronic device e.g. wireless telephone, has user interface that associates events with movements applied by user and analyzes principal motion vector that is determined by motion detection unit

摘要

The device has a motion detection unit detecting movements applied by a user based on an analysis of two successive images taken by a camera. A user interface associates events with the motions and analyzes a principal motion vector that is determined by the detection unit. The interface associates events with the vector, if the vector responds to predetermined criteria such as an amplitude or direction of the vector. Independent claims are also included for the following: (a) a distinct event associating method for user interface of a portable electronic device equipped with a camera (b) a computer program for a portable electronic device.
