These systems differ from earlier in-vehicle instruments and displays in that they may require higher visual and cognitive loads and may also take greater advantage of voice commands and auditory presentation of information. The model developed for evaluation was composed of five driver attention demand components: visual, auditory, supplemental information processing, manual, and speech. The fundamental idea was to develop a new computer program that would assess the resources required of the driver when performing in-vehicle tasks using these complex systems. This document is a short user manual describing the primary functions of the IVIS DEMAnD (Design Evaluation and Model of Attentional Demand) prototype software
