Abstract

A portable communication device may include a motion detection unit adapted to measure movement related data, a processing unit adapted to receive the movement related data from the motion detection unit, and at least one light emitting element adapted to receive control signals from the processing unit. The processing unit may be adapted to compute a lighting scheme that determines when to activate and when to deactivate the at least one light emitting element based on said movement related data, and to send control information according to said lighting scheme to the at least one light emitting element for activating and deactivating the at least one light emitting element, such that the at least one light emitting element, when the portable communication device is moved over a region of space, may create an illusive display adapted to convey information using persistence of vision of a viewer.
