It contains three cells of 32-pins each that rise and fall as the cursor moves over a graphic on the computer screen. The student places his hand on the mouse, gently resting his fingers on the three cells. With the software that comes with the device, graphics can be labeled so the student can receive an auditory description of various parts of the graphic. Training Training is a critical issue for the students using the tactile mouse. The Virtouch system comes with training software that teaches the student in a logical and sequential manner how to use the mouse.
Students begin by tracing simple vertical and horizontal lines on the screen.
They progress through intersecting lines and basic symbols of everyday objects such as a chair and a house. As students become familiar with the mouse, more complex items are introduced such as basic travel routes, the school map, and teacher created graphics. The teacher can then label various parts of the map so the student can obtain an audio description at key points. Games enhance the learning process.
