Eye controlled wheelchair technology for indoor
and outdoor use
MyEcc Pupil is a more advanced version of the tried and trusted MyEcc designed for eye-cont-
rolled wheelchair operation with or without a display in the field of vision� The lightweight plastic
headset with an attached sensor tracks the user’s eye movement and the MyEcc Pupil Control
transfers the data to the power chair via the software� As well as wheelchair control, the device lets
users change their seating position and operate robotic arms like the KINOVA JACO®�
There is no need to install software, just copy a folder� Window size and relay activation are ea-
sily changed using a file included in the pack� We have taken great pains to maximize safety and
reliability� The entire chain of command from eye to wheelchair is monitored� To stop the chair
(emergency stop function), you only have to close your eyes�
