In-vehicle infotainment systems (IVIS) of tomorrow must meet very high demands for interaction safety, ease of use and flexibility. The growing functionality of IVIS pushes the development of entirely new interfaces that overcome limitations of the current designs. In this thesis we implemented and tested “Remote View” – an interface that adds a head-up display to a conventional touchscreen interface in order to improve secondary task safety. We implemented four variants of Remote View interface using touchscreen and touchpad as input devices. For comparison, conventional touchscreen interface and touchpad input for touchscreen were also tested. The main goal of this thesis was to test safety impact and acceptance of a new hybrid interface comprising Remote View. We hypothesized that Remote View would have allowed to use touchscreen graphics user interface (GUI) more safely without compromising the flexibility and usability of interaction. This thesis covers: prototype development, real-traffic test experiment (design and performance), and both safety and usability analysis for Remote View interface. The real-traffic experiment was conducted with 22 participants using an instrumented EuroFOT vehicle on a public highway in Gothenburg, Sweden. EuroFOT is the largest European on-going project collecting real-traffic data for intelligent vehicle systems evaluation. Our results show that, on average, participants felt safer and more comfortable using Remote View than conventional touchscreen interface while performing secondary tasks. However, the objective metrics neither support nor contradict this feedback from the participants. In addition, it was found that controlling a remote screen with touchpad provides a good compromise between conventional touchscreen interface and Remote View. In conclusion, we recommend 1) further research and improvements for Remote View and 2) use of touchpad for GUI interaction. This study was performed as a part of Master’s thesis at Chalmers University of Technology for Volvo Car Corporation.
