Man-Machine Interface Of Tristan

This report describes a console system which is the essence of man-machine interface used to operate TRISTAN. Ergonomic design and its implementation has been done in construction of the TRISTAN Central Control Room (TCCR) and Operator's Console (OPC). The environment of the console is designed to minimize fatigue, eyestrain and discomfort by optimizing light fixtures, minimizing noises made by fans or footsteps and harmonizing colors and brightness throughout the control room. The OPC is composed of a special supervisory console at the center and five identical standard consoles. The difference between the two types is that hard-wired switches which manipulate beam gates and related equipments to assure the safety of personnel are mounted only on the former console. The safety system is based on the hardware techniques similar to those have been accepted for the control of critical industrial installations. Each of the consoles contains ten color TV monitors, two high resolution graphic display monitors and two touch-panels with color character display monitors. Each console is managed by a minicomputer of the TRISTAN control computer network. The graphic displays are connected directly to the computer. The touchpanels and the corresponding character video RAM modules are through CAMAC serial highway.
