Abstract

Our aim is to improve an HMI that reduces the workload by distributing the different resources (visual / auditory / verbal / spatial etc…) related with human's recognition. In this study, the effect on the driver's workload is clarified by comparing two types of operations: the current voice operation as single modal, and the operation uses gaze pointing and voice command as multi modal. Regarding to gaze and voice control, there are 2 use cases that are more effective than the current voice operation. It was confirmed by subjective evaluation (NASA-TLX) and objective evaluation (Prediction Error) at the driving simulator tests.
