Italia The construction of SeebyTouch Deutsch
Open unit SeebyTouch consists of a tactile display and a software which translates customary computer pictures for this unit.
The tactile display consist of a stationary and a mobile unit connected over trusses. A power supply and a serial- or USB-port are parts of the "stationary unit". The mobile unit has a push-button and a computer mouse for position sensing. The position dependant output takes place by the tactile matrix consisting of 5 braille-cells. In addition, the "mobile unit" contains a power supply for the braille-cells and a microcontroller, controlling all input and output. Detail
Software The software translates any type of pictures from the computer to the tactile unit. The user can choose from many various settings to optimize the transformation from a visible to a tactile picture. The software is available for almost every computer, because it is running on ten operating systems (Linux, Windows, OS X, ...).
