Analysis of eye movements in different tasks related to the use of lift trucks.
Fork-lift trucks are frequently involved in industrial injuries that happened during driving. Insufficient visibility is one of the leading causes of occurrence of these accidents. A previous study (Hella et al, 1988) showed that +/- 75 mm is the maximal amplitude of head movements recorded to avoid the mast. However, very little is known about the areas of the forward field of view that are most frequently fixated by the eye. This article presents the results of two analyses of eye fixations during several driving situations of a lift truck that could provide a wealth of useful information for designers and for standardisation. The information it contains is also of interest in analysing visibility from all industrial vehicles.
