Abstract
Challenging environments pose difficulties for terrain
navigation, and therefore wearable and multimodal
navigation systems have been proposed to overcome these
difficulties. Few such navigation systems, however, have
been evaluated in field conditions. We evaluated how a
multimodal system can aid in navigating in a forest in
the context of a military exercise. The system included a
head-mounted display, headphones, and a tactile vibrating
vest. Visual, auditory, and tactile modalities were
tested and evaluated using unimodal, bimodal, and
trimodal conditions. Questionnaires, interviews and
observations were used to evaluate the advantages and
disadvantages of each modality and their multimodal use.
The guidance was considered easy to interpret and helpful
in navigation. Simplicity of the displayed information
was required, which was partially conflicting with the
request for having both distance and directional
information available.
