| As the in-vehicle information and entertainment system (IES) and the variousapplication integrated in people’s car, new human-machine interaction ways havebeen applied to the driving environment after redesign the relationship betweenpeople and their car. Faced with an increasingly complexity of in-vehicle applicationconfiguration and operational level of the IES, new interaction modes can solve theconflict between safely driving and handling all kinds of real time information tosome extent. However, driving task needs heavy cognitive load, the most importantprerequisite of human-vehicle interaction must be driving safety. Intuitive interactiondesign will enhance the driving performance by offer an unconscious operation way,thus provide us a new way of thinking in the safety human-machine interaction.Eye movement technique has long been used for detecting driver’s eye movementmode and their driving behavior; it’s also used to aiding transport design to insure thedriving security. The former focuses on the driver’s psychological mode, and on theeye movements under different driving environments for the sake of enhancingdriving safety. The latter focuses on the automotive interior configuration of thedevice, and on the eye movement mechanism in third-party devices to enhance drivingsafety. However, the driver’s intuitive eye-movement interaction are not beenexplored based on the IES. Head-up-display (HUD) offer a proper research supporterfor keeping the driver’s view on the road while reading essential informationpresented by the IES. Therefore, the main task of this research is to exploreeye-movement interaction as a new interaction way used in vehicle music control.This study focuses on the following aspects: current research state of eye trackingtechnology and eye-movement interaction; human-machine interaction modes andautomotive user interface; the influence of driver’s driving awareness and drivingdistraction on human-vehicle interaction; and explore the natural semantic meaning ofeye movement base on the vehicle music control. Then combine theoretical researchand field research, present an intuitive interactive design method based onhuman-centered design. An eye-movement interaction model is been establishedthrough the problem-behavior graphs analysis, further understand the intuitive eyemovement mechanisms to present and iterate eye-movement interaction prototype. Finally, through the experiment to test and evaluate the intuitive operation workflowand to what extant this prototype will influence the driving safety.Innovations of this research include following points: eye movement interactionas a new interactive mode that are used in in-vehicle music control; usingproblem-behavior graphs as approach to explore user’s intuitive thinking method, andthen assist intuitive design development; eye-movement interactive prototype designbased on the vehicle HUD.The content in this paper involve eye tracking techniques, field research,prototype development, prototype testing and interaction design. The results of theresearch can be a reference for the further study of as eye movement interactiondesign, HUD design and intuitive interaction design approach. |
