EPIC Overview

This video shows the general capabilities of the multi award winning EPIC sensor. As application examples, this video will trigger your imagination into the world of opportunities that the EPIC sensor will give.

Movement and gesture applications of EPIC sensors

This video demonstrates how EPIC can be used to determine the position of a hand or body by measuring signals from a pair of sensors. It shows how hand position sensing enables gesture recognition and therefore device control.

This simple demonstration shows how the application can be extended to cover body position within a room to enable automatic switching, security surveillance or assisted healthcare.

2D Movement and gesture applications of EPIC sensors

This video demonstrates how EPIC can be used to determine the position of a hand or body by measuring signals from a series of sensors. It shows how hand position sensing enables gesture recognition and therefore device control.
