Abstract: Users of mobile
systems often simultaneously perform some other task, and
multimodality tends to give them greater opportunities to
do so. One goal in the design of mobile multimodal systems
should therefore be the support of effective user multitasking.
Previous research in several areas has made many contributions
that are relevant to this goal, but some key issues require
further work. Using the example of voice dialling with a mobile
phone, we discuss task analysis of two voice dialing methods,
showing how much such analysis can help to identify possible
obstacles to the simultaneous performance of voice dialing
and other tasks. Detailed observations of users doing multitasking,
supplemented with survey results, confirm that these analyses
capture important aspects of the multitasking problem; but
also that user's decisions and behavior are strongly influenced
by factors not covered by the task analyses, such as prior
experience and beliefs about social acceptability. Conclusions
are drawn concerning the implications of this research for
design methods and for future research in support of multitasking.
