abstract="Recent studies have shown that statistical indices of spatial dispersion computed over the distribution of fixations could be effectively used to derive a stable measure of the cognitive resources allocated to a task. This approach is particularly appealing, given that it allows computing a workload value with a 1-minute resolution, thus making it possible to use it as a trigger for some adaptive systems. The present study reports two experiments aimed at separating the contribution of two types of demands (temporal and visuo-spatial). Results showed that temporal demand led to dispersed pattern, whereas visuo-spatial demand led to grouped pattern of fixations.<p /><p>Language: en</p>",
