For the ACCESSPACE project, we plan to use a belt equipped with a set of vibrators to convey information about environment. The actual model propose to use 48 vibrators distributed on three lines around the belt.

We developed a PC-Tactibelt interface based on an Arduino Mega, and a custom shield to power vibrators with an external battery. The interface allows to control vibrators individually, and applying specific pulses.

For preliminary tests, we placed a line of 16 vibrators on the belt, and developed a 2D simulated environment based on the environment used during for my PhD. Continuous vibrations indicate the presence of obstacles. Vibrations becomes stronger when moving closer to walls. A pulsed vibration indicates the direction of the target to reach (mauve disc). Several vibration patterns are used to indicate navigation points, landmarks or empty directions.
