Comparative Evaluation of Five Touch Entry Devices.

摘要

Computers and their corresponding interactive display and control devices were, at one time, available to a limited user population. With technological advancement, human computer interaction has become accessible to a larger user population through the use of electronic displays and their associated input devices. In the early 1960s, the use of the display plane as an interactive surface was realized by E. A. Johnson at the Royal Radar Establishment in Hurn, U.K. (Orr and Hopkins, 1968). The input device subsequently designed and developed is referred to here as a touch entry device (TED). TEDs take advantage of the natural mode of pointing, as do light or sonic pens, without the need to use a stylus or additional cumbersome wirings. Many technological approaches to touch entry have been developed and implemented since its first inception. However, the operational characteristics of each TED must be considered in the application of these devices to disparate types of tasks.
