A touch sense device (TSD) implements an electrical pulse technology to mimic a Braille dot includes a series of sensor cells. A sensor cell consists of eight dots is composed of an anode (+) and cathode (−) electrodes with each dot arranged in a two by four matrices portraying a Braille syntax. Depending on the Braille characters, low electrical currents are passed through different positioned anodes, when touched by a finger delivers currents to the cathode completing the electrical circuits forming character dot(s); there provides a communication device for reading, writing, editing, and/or social media interactions for the visually impaired individuals.
