Abstract
Techniques are presented which enable conventional "light-pen" tracking and pointing functions to be extended to the direct view storage tube (DVST). The schemes eliminate the high data transfer rates or considerable buffer storage required even for static displays when short persistence cathode ray tubes (CRTs) are used. Two solutions, a "quadruple photo-sensor pen" and the "potentiometer pen" (a transparent resistive sheet and stylus combination which covers the display), are described and compared.Keywords
