The general topic of investigation is the
subjective and aesthetic impact of multimodal and in particular
haptic feedback when incorporated into embedded manual controls.
For example, we are interested in changes in the user's
sense of security, confidence, and aesthetic preference
as compared to the same parameters when using non-multimodal
interfaces. This is in contrast to a study of performance
factors that are more easily measured quantitatively - e.g.
speed of operation, number of errors, performance impact
on primary driving task, etc.
