Designing in-vehicle gestural interfaces - Minimising visual distraction
Examensarbete för masterexamen
Interaction design and technologies (MPIDE), MSc
The vehicle industry of today is always striving to introduce new innovations and new concepts are being presented by the week. The eager to always be the leading manufacturer within technology and infotainment may sometimes affect safety. This master thesis aimed to utilise gestural interfaces in order to minimise visual distraction when using in-vehicle infotainment systems. This is especially important due to touchscreens’ lack of tactility. The design process of the thesis has had a human-centered approach and involved potential users in each iteration, assu ha h us s’ c nc p i n and m n al m d l was ak n in consideration when design concepts were developed. During the project, a questionnaire regarding fast access to controls in a vehicle was used as a foundation. The process included a number of iterations to find an intuitive mapping between gestures and features in a vehicle and resulted in two concepts, which both were evaluated further. One of the two concepts was later considered the more promising one to continue development and testing with and was named GABI (Gesture Action Based Infotainment). The concept incorporated an underlying pattern to achieve inner logic and coherency, and thus simplify for users to learn and remember. The GABI prototype was lastly evaluated in a driving context, measuring learnability and experienced workload. Findings from the driving test indicated that the participants were able to learn the system with reasonably few iterations and were generally positive towards using the system. Conclusions from this thesis were that designs using gestures should conform to conventions whenever it is possible to do so. By providing an inner logic, users will learn the system faster and facilitate to make sense of the complex. Having done initial acceptance tests for GABI, more tests are necessary, to measure and compare the distraction and ensure safe interaction for the driver.
