研究了外设微型阴极射线管位置对双任务性能的影响，阴极射线管提供二次任务信息。微型CRT的位置在三个高度和四个方位角上变化。主要任务信息是通过一个固定的、位于中央的CRT来呈现的。主要任务需要连续监控主要显示器，而次要任务需要连续跟踪次要显示器上的对象。结果表明：随着显示器在方位角上的距离增加，两项任务的表现都有所下降；当需要眼睛向上移动以观看次要显示时，性能下降比需要眼睛向下移动时更大；受试者对不舒服程度的评分与表现下降的一般模式相似。本文还讨论了这些发现对二次显示器设计的意义
Dual task performances were investigated as a function of the location of a peripherally mounted miniature CRT (cathode ray tube) which presented secondary task information. The location of the miniature CRT was varied across three levels of elevation and four levels of azimuth. Primary task information was presented by means of a stationary, centrally located CRT. The primary task required continuous monitoring of the primary display, while the secondary task required continuous tracking of an object on the secondary display. The results indicated that: performance on both tasks declined as the displays' separation along the azimuth increased; performance decrements were greater when upward eye shifts were required to view the secondary display than when the corresponding downward eye shifts were required; and subjects' ratings of discomfort were similar to the general pattern of performance decrements. The implications of these findings for the design of secondary displays are discussed.<<ETX>>
