IMPROVED DISPLAY BY MOVING A PORTABLE COMMUNICATION DEVICE WITH LIGHT EMITTING ELEMENTS

摘要

A portable communication device comprising a motion detection unit adapted to measure movement related data. The portable communication device also comprises a processing unit adapted to receive movement related data from the motion detection unit. Further, the portable communication device comprises light emitting elements adapted to receive control signals from the processing unit. The processing unit is adapted to compute when to activate and deactivate the light emitting elements. Further, the processing unit is adapted to send control information to the light emitting elements for activating and deactivating them, such that the light emitting elements, when the portable communication device is moved repetitively over a region of space, creates an illusive display. The illusive display is adapted to illustrate information using persistence of vision of a viewer. The present invention also relates to a method for creating an illusive display, a computer program and a system comprising a mobile terminal and an adaptor unit.
