Design can be art. Design can be aesthetics. Design is so simple, that's why it is so complicated.

Kitajima, Muneo and Akamatsu, Motoyuki (2009): Information for Helping Drivers Achieve Safe and Enjoyable Driving: An On-Road Observational Study. In: Proceedings of the Human Factors and Ergonomics Society 53rd Annual Meeting 2009. pp. 1801-1805.
In this study, a series of on-road observations were conducted to derive information necessary for safe and enjoyable driving. Four pairs of participants were chosen from among those responding to a Web survey and attending a follow-up interview. Each pair was asked to drive six routes. Three of the routes were familiar to one of the pair and new to the other, with the former serving as navigator and the latter serving as driver. For the other three routes, the roles were reversed. Three interviews were conducted, one coming after two drives in which the pair played both roles, in order to derive information considered necessary for safe and enjoyable driving by the participants who served as driver on routes unknown to them. Three kinds of information for safe and enjoyable driving were identified: 1) guidance for routing, 2) support for safe driving, and 3) provision of miscellaneous information, such as information about daily topics of interest to the driver and information about interesting things to see along the route.

Akamatsu, Motoyuki and MacKenzie, I. Scott (1996): Movement Characteristics using a Mouse with Tactile and Force Feedback. In International Journal of Human-Computer Studies, 45 (4) pp. 483-493.
A multi-modal mouse incorporating tactile and force feedback was tested in a target selection task with 12 subjects. Four feedback conditions (normal, tactile, force, tactile+force) were combined with three target distances and three target sizes. We found significant reductions in the overall movement times and in the time to stop the cursor after entering the target. This effect was particularly pronounced for the tactile condition and for small targets. However, compared to normal feedback, error rates were higher with the tactile and tactile+force conditions. The motor-sensory bandwidth calculated using Fitt's law, normalized for spatial variability, was highest in the presence of tactile feedback (6.4 bits/s). This was followed by tactile+force (6.2 bits/s), normal (5.9 bits /s), and force feedback (5.8 bits/s). These results indicate that modifying a mouse to include tactile feedback, and to a lesser extent, force feedback, offers performance advantages in target selection tasks.

Akamatsu, Motoyuki and Sato, Sigeru (1994): A Multi-Modal Mouse with Tactile and Force Feedback. In International Journal of Human-Computer Studies, 40 (3) pp. 443-453.
We have developed a mouse with tactile and force feedback. Tactile information is provided to the operator by a small pin which projects slightly through the mouse button when pulsed. Force information is provided by an electromagnet inside the mouse in conjunction with an iron mouse pad. Tactile and force feedback are controlled by software linked to the visual information of targets on the visual display. In an empirical evaluation using a target selection task, the addition of tactile and force feedback shortened the response time and widened the effective area of targets. Design issues for interactive systems are discussed.
