Conversational Interface for Secondary Tasks While Driving a Car

This thesis deals with interaction with car infotainment using a conversational interface with respect to the target group of older drivers. The main objective of this work is to analyse the behaviour of older drivers while performing secondary tasks using a conversational interface while driving and to design this interface according to their needs. These secondary tasks were specified in use-cases of navigation and message-sending. For evaluation of designed low-fidelity prototype of a conversational interface, two experiments in qualitative studies were conducted. The outcome was a final design of a conversational interface used to control secondary tasks by older drivers and also insights about their behaviour in these situations.
