The automotive industry is moving towards autonomous driving, and as more driving task responsibilities are transferred to the motor vehicle, the driver can engage in more non-driving tasks. In this project, we have investigated driver behaviour with so called secondary tasks (STs) in semi-autonomous motor vehicles, and how an human-machine interface (HMI) for digital communication, and other STs, can be designed for this level of autonomy. We have sent out a survey, created concepts, implemented low- and high-fidelity prototypes, and conducted user tests, in order to find a solution which is both comfortable, efficient, and safe to use while driving. Our solution consisted of a system with an head-up display (HUD) by the windshield, and two touch sensitive trackpads mounted at either side of the steering wheel. The trackpads control the content shown in the HUD, by using common touch gestures, such as pressing, swiping, and typing with our own interpretation of a T9 input method, which we call Circular T9. In the end, we had insufficient data to conclude whether our solution was safe enough in a real driving setting. The feedback from the user tests have been generally positive towards the concept, but critical towards the high-fidelity prototypes, specifically that there is insufficient feedback from the input interface. Our hope is that this project will inspire other projects in designing HMIs for future motor vehicles.
