Lateral Motion Pin Device for Tactile Communication

This project introduces a new concept of tactile display based on lateral motion of the contact pins. Unlike traditional tactile devices where pins are arranged in an array and move upwards/downwards, a single row of pins moves laterally on a rail to display tactile information as in a 2D matrix. The advantage of this concept is that a row of N actuators can display some information that has been traditionally done with a matrix of N x N actuators. An electromechanical actuator based on miniature DC motors has been designed and implemented to create such lateral motion.
