Design of an interactive vacuum fluorescent information display system

The objective of this project is to design and evaluate an interactive terminal using vacuum fluorescent technology. The display tube used is six lines by forty characters wide to enable to display 240 characters of display data. The touch input panel uses infrared switch matrix optical technology to transmit the operator's interaction to the host system. A detailed explanation of design philosophy will be presented and a comparison between various types of touch input technologies will be discussed.
