Abstract

A wearable projector system includes a projector device and a portable device communicated with the projector device. The wearable projector system includes at least one signal generator, a projector and a control unit. The signal generator transmits wireless signals. The projector outputs projection contents. The portable device includes a plurality of sensors and an operation unit. The sensors detect a position of the signal generator and generate a position signal. The operation unit determines an adjustment displacement of the projector device according to the position signal and generates an adjustment displacement signal representing a displacement between the projector device and the portable device. The control unit adjusts a projecting direction and a projected frame shape of the projector according to the adjustment displacement signal.
