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 pilot’s 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 question 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). These two displays were used to manipulate the resolution variable as they were each used only in their native mode. Usability was tested with three different tasks at varying fields-of-view (FOV). The tasks required finding and reporting information displayed from: 1) aviation approach plates, 2) FalconView mission planning software, and 3) pseudo-checklists. For the checklist tasks we also manipulated font size to more precisely investigate readability. 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.
