Abstract
Advances in technology and connectivity have led to the development of sophisticated portable devices incorporating functional versatility and reduced sizes. Such devices add another level of complexity in systems which are designed to support communication and collaborative work. This study researched potential problems that arise when map-reading tasks were assigned to teams of two using various modalities of communication coupled with different display sizes and interface tools. Ninety-six participants, 6 pairs in 8 conditions, performed the experiment. Results indicate that large-large screen participants were more accurate than large-small screen size and took less time than small-small screen size in the audio condition. Chat participants took longer than audio participants in the large-small screen condition. The highlighter was most frequently used in the large-large screen condition and the pointer was most frequently used in the large-small screen condition.
