A general principle for all user interface design is to go through all of your design elements and remove them one at a time. If the design works as well without a certain design element, kill it.

Weinberg, Garrett, Harsham, Bret, Forlines, Clifton and Medenica, Zeljko (2010): Contextual push-to-talk: shortening voice dialogs to improve driving performance. In: Proceedings of 12th Conference on Human-computer interaction with mobile devices and services 2010. pp. 113-122.

We present a driving simulator-based evaluation of a new technique for simplifying in-vehicle device interactions and thereby improving driver safety. We show that the use of multiple, contextually linked push-to-talk buttons (Multi-PTT) shortens voice dialog duration versus the use of a conventional, single push-to-talk button (Single-PTT). This benefit comes without detriment to driving performance or visual attention to the forward roadway. Test subjects also preferred the Multi-PTT approach over the conventional approach, and reported that it imposed a lower cognitive workload.

Dietz, Paul H., Harsham, Bret, Forlines, Clifton, Leigh, Darren, Yerazunis, William, Shipman, Sam, Schmidt-Nielsen, Bent and Ryall, Kathy (2005): DT controls: adding identity to physical interfaces. In: Proceedings of the 2005 ACM Symposium on User Interface Software and Technology 2005. pp. 245-252.

In this paper, we show how traditional physical interface components such as switches, levers, knobs and touch screens can be easily modified to identify who is activating each control. This allows us to change the function performed by the control, and the sensory feedback provided by the control itself, dependent upon the user. An auditing function is also available that logs each user\'s actions. We describe a number of example usage scenarios for our technique, and present two sample implementations.
