**Description**

The VT2 is an eye detection bar standing over 2 inches in height and over 19 inches in length. The device weights about 3 pounds. The VT2 can be used from short distances as well as from long distances. The furthest distances ranging from 25-39 inches. The VT2 is compatible for Mac and Windows users and can function on monitors up 30 inches. A USB port is also necessary for use of the VT2.

**History**

Eye Tech Digital Systems was founded by Robert Chappell and Melinda Trego in 1996. The Eye Tech Digital Systems organization is located in Mesa, Arizona. To date, Eye Tech Digital Systems offers 6 eye tracking devices for consumers who wish to use these devices with different sized laptop computers, desktop computers and television screens. Eye Tech Digital System’s goal is to continue to expand on what they offer with both cost effective and universal systems to meet all needs.

**Impact on Teaching and Learning**

The VT2 is most beneficial in the Special Education field, particularly in terms of assistive technologies for those with severe disabilities such as cerebal palsy. Students that have disabilities which have limited the use of their arms, hands, feet, and even vocal functions can make use of VT2 by still being able to use computer programs to aid learning. Students can surf the internet, type using programs like Microsoft Word, and play educational games. With VT2 and similar eye tracking devices, students with disabilities can continue to learn in this modern technology driven world.

**Practical Applications**

VT2’s most practical application is that it acts as a computer mouse. For most people who use a computer, they control via the mouse and keyboard, which have to be manipulated through use of the user’s hand and fingers. The VT2 serves as an alternative to a physical computer mouse that is controlled not by a hand and fingers but rather by eye movement.
