EyeTech Quick Glance TM4

Although not a communication aid in itself, the Quick Glance TM4 is a unit that plugs into most PCs to give eye gaze control (it's shown here attached to a Powerbox communication aid, but you can attach to other suitable PCs, aids and laptops). Mouse 'clicking' can be done with an eye blink, or by staring (dwell). A separate switch and switch-adapted mouse can also be used.

Unlike the earlier TM3, which had a mains power cable and a separate Firewire connection lead, The TM4 needs only a single USB2 lead which plugs into the PC or communication aid. 

The TM4 is supplied with it's own Eye Tools software, which runs in the background while the user is working with standard Windows applications and speech output software. It also allows calibration of the unit (5, 9 or 16 points) and gives control over such settings as dwell time and zoom. The TM4 tracks either or both eyes for increased accuracy and range of head movement. You can save the settings for more than one user.

You can also adjust the TM4 settings from within The Grid and Mind Express communication software, which offer a few extra options such as a picture as a calibration marker.

The unit is designed to fit under a standard flat screen monitor, but you can choose various mounting brackets for attachment to laptop computers (it sits on top of the keyboard) or wheelchair mounting systems. It requires a 30.5cm to 53cm monitor.
