Touch Panel System; Design and Development

摘要

The computer keyboard can sometimes be difficult to use, especially with the number of different types that are manufactured. The touch panel concept eliminates the need for a keyboard to use a computer. The touch-panel works on a light sensor idea whereby breaking a beam of light causes an entry to be made into the computer. It is much easier than having to type the entries on a keyboard. The programmable switch array detection and selection system, commonly referred to as a touch panel, is an alternate way of entering data and instructions into a computer. The operator communicates with the host computer by breaking beams of light, which causes a data entry to be made. The programmable switch array was designed and developed for the Data Handling/Recording System (DH/RS) as an auxillary input device for near real time interpretation of imagery. This report is a summary of the design and development of the touch-panel system during the summer of 1984. Included in this report are the system interface design, physical characteristics and electrical circuitry.
