Bewertung eines Head-Mounted- und eines Hand-Held Displays bei einer Zielerkennungsaufgabe

摘要

New information technologies such as Helmet-Mounted Displays (HMD) are used to support task accomplishment in many areas of human activities. Favored areas are diagnosis, assembling and orientation tasks. A main advantage of HMDs is that additional information essential for the task execution can be projected directly into the field of view of the operator and additional eye move-ments, which might detract from the external view, are not necessary. But there are also disadvantages. If the density of presented information is too high the visibility of the external world might be degraded. Information on the HMD can also distract the attention of an operator from the external view. A reduced transparency of the HMD's mirror can affect vision and impair color perception. It is considered that a high frequency of accom-modations cause eye strain, headache and similar discomforts. Finally, the low wearing comfort resulting from the weight of the helmet or visor, unbalanced point of gravity of the system etc. leads to performance degra-dation and feelings of discomfort. Unfortunately, there is only few infor-mation on such factors and only a small number of empirical examinations have been attempted.%In der vorliegenden Untersuchung wurde ein Head-Mounted Display mit einem Hand-Held Display bei einer Zielerkennungsaufgabe verglichen. Dabei wurden Leistungsmaße sowie subjektive Maße für die Beanspruchung und die Simulatorkrankheit erfasst. Während bei den Leistungsmaßen keine signifikanten Unterschiede zwischen beiden Displays festgestellt werden konnten, wurden beim Head-Mounted Display eine deutlich höhere Anspannung und Ermüdung sowie Symptome der Simulatorkrankheit beobachtet.
