Interaction concepts in a rotary haptic device for browsing through lists in an integrated infotainment system

Abstract [en]

The purpose of this thesis was to design and evaluate different interaction concepts for navigating through long lists of information in an integrated infotainment system. The interaction was made with a rotary haptic devices . Does the haptic feedback provided through the device affect user performance? During the course of this master thesis a test environment was built and designed to examine just that. Through preliminary investigations four interaction concepts were designed for the test. In the first concept a haptic click was provided for each list entry, in the second no clicks were provided, the third concept was designed as a jogg-shuttle and the fourth had an acceleration script. The test environment was created using Macromedia Director and a rotary haptic device supplied by ALPS. A usability test was carried out in May 2006 using 12 participants and the “Labb-Jakob” driving simulator at Open Arena Lindholmen. The participants got to solve tasks while driving on a simulated road. The list lengths in the tasks varied between 10 and 400 steps The participants performance was measured in time, turn over errors and workload. In between each test round the participants were asked to fill in a NASA-RTLX form, a form designed for measuring the subjective workload of the participants. The results showed that participants performed best with concept 1 in shorter tasks, and performed best in longer tasks with concept 4. The participants performed significantly worst through out all task ranges with concept 3. When looking at turn over errors, that is the number of times per task the target is passed, participants performed significantly better with concept 1 than with concept 3 and better but not significantly so than the other two interaction concepts. The NASA-RTLX forms revealed no significant differences between the four interaction concepts. The results of the test show that interaction concepts in rotary haptic devices can indeed have an effect on user performance in the human-machine interaction both to the better and to the worse. An interaction concept such as concept number 4 which performed well in the test can enhance user performance. Based on the results of this master thesis the recommendation is to investigate an interaction concept with clicks and an acceleration script. This would hopefully result in an interaction concept with the precision of concept 1 and the speed of concept 4.
