Photograph, Candidate Devices for Computer Screen Interaction

Photograph, Candidate Devices for Computer Screen Interaction

Usage conditions apply
This black and white photograph shows three possible devices for interaction between a computer user and a computer screen that were tested at SRI in 1964 and 1965. On the right is a computer mouse, in the middle a joystick, and on the left a Grafacon. A light pen and a knee control also were tested – use of the mouse produced the fewest errors (see 2015.3073.01).
