A study of computer manual input devices and their associated human engineering characteristics was conducted for the purpose of developing a scheme for relating these devices to operator performance characteristics, computer characteristics and system requirements. Conventional commercially available input devices such as pushbuttons, toggle switches, joysticks, etc. were surveyed. Available literature pertaining to human performance with such devices was reviewed and summarized. The suitability of devices and availability of applicable performance data are related to a generalized operator task family by a set of tables. Results of the study show a wide variety of available devices, inadequate research data establishing performance for various devices and device character istics, and incomplete specification of operator input tasks in existing systems.
