The touch screen is still available for making selections, even when the software is set to use Eye
Tracking as the selection method. This is for the benefit of a caregiver, who might need to make
occasional software adjustments.
In those situations, the caregiver may want to cover the EyeMax camera with his/her hand, or a
self-adhesive note pad, so that his/her eyes do not trigger an unintended selection in the software.
