How to build a low-cost evaluation framework for in-vehicle interfaces

Based on our experience developing the driving simulator for this experiment, my colleagues Jaka Sodnik and Grega Jakus and I propose a low-cost, laboratory based testing framework for in-vehicle interfaces. Exemplified by a comparison between an auditory interface, a Head-up display (HUD), and a combination of both we show how task completion times, driving penalty points, mental workload, and subjective user evaluations of the interfaces can be collected through different logging systems and user questionnaires. The driving simulator used in the experiment enables the simulation of varying traffic conditions as well as different driving scenarios including a highway and a busy city center. The framework will be presented at the 5th International Conference on Advances in Computer-Human Interactions (ACHI 2012).
