There have been rumors for a while, but today Dynavox has formally announced eye gaze control for the Dynavox Vmax coming in the fall. They are calling the device the EyeMax. It has been designed working with the folks at Eye Tech. The EyeMax will be an add-on accessory, it works via USB connection and is compatiable with any VMax that has 512MB or 1GB RAM for memory. Individuals at dynvaox have told me that they believe it accomodates extranneous head movement as much as any other device out there, including the Tobii, but that a full evaluation with the EyeMax should be done before ordering*.
Dynavox believes that having the EyeMax being an add-on access piece (like a switch or track pad is) will work better for folks with progressive disorders like ALS, muscular dystrophy and mitochondrial disease. Thus the EyeMax can be ordered when it is needed, as opposed to buying one device that become obsolete and then having to replace it with a device that has integrated eye gaze control. My only concern is the usual concern, funding. Maybe, just maybe the powers that be of funding will realize it is cheaper to buy one device and add an EyeMax later, but somehow, I doubt it.
*(Ed's note - obviously a full eval with device and access should always be done before ordering)
