Blind also on the internet
The Israeli association Virtouch Ltd. has just marketed the VTS system (Virtual Touch System). From now on blind people will be able to "see" the computer screen graphics, read Internet texts or use video games. They only need three fingers and a computer rat tool. The instrument consists of 6 buttons that interact directly with the screen and 32 ultrasonic needles located in a rectangle under each finger. As the blind moves the cursor through the screen with one hand, the mouse sends the user what appears on the screen through soft needle movements. However, the price of VTS is of advantages: 600,000 sts. environment.
Now we are studying the VTS system that will transmit the colors: if it is a cold (blue) or hot (red) color, it will emit a heat of different intensity.
