Abstract:

As display technology moves forward, we are seeing the replacement of paper information in cockpits with digital information. Soon the stack of paper carried on the pilots knee will be replaced with a digital kneeboard in which the information will not only be displayed, but also manipulated and changed. There are several options for viewing this information, including both a helmet-mounted display HMD, a small display that rests on the knee replacing its paper counterpart or is mounted in the airframe. However, in either case the questions arises as to what are the resolution and field-of-view requirements for optimal performance of various tasks. We examined the readability and task performance using the Antelope Technologies Rugged Handheld 01 display which has a resolution of 1024 x 768 XGA, and the ADR model FG-8000 display with a resolution of 800 x 600 SVGA. Results are discussed in terms of both FOV and resolution requirements for each of the tasks. Several recommendations are given for both display requirements as well as tests for examining usability of digital kneeboards.
