The idea of FLIPPS is to design, implement, and evaluate a vibro-tactile device that is composed of a photo diode, vibro-tactile stimulator, microcontroller and power supply. The stimulator is attached to the finger tip and activated when light illumination exceeds a defined threshold. The subject (blind person) receives the reflected light from the objects and, based on brain plasticity principles, can interactively learn to construct a mental image of the objects and of the scenery. The FLIPPS idea is based on sensory substitution theory; here, substituting visual inputs by haptic vibrations.
