Research On Human-Machine Interaction Of Electric Vehicle Navigation System Based On Eye-Movement Information

The electric vehicle as a new energy vehicle will be an important direction of the future development,but the current electric vehicles compare with the traditional fuel vehicles,only change of energy and transmission way;there are no too big changes in the human-vehicle interaction.With the development of mobile Internet,vehicle information system functions are more and more complex;The drivers have to do more and more interactive operations,while driving;Driving distraction is more serious.New human-vehicle interaction is required,it need to satisfy the driver's need of information handling,and ensure the safety of driving.Eye movement technology has been widely used in automobile driving,but it is mainly used to detect driver's driving behaviors.At the same time,cyc-movement interaction as a kind of intuitive interactive way is feasible to apply in vehicle.The HUD has also been developed,it can project the vehicle information directly on the windshield and reduce the change of the driver's vision and focal length to improve the efficiency of information acquisition and driving safety.Therefore,the electric vehicle using eye-movement interaction and head-up display to improve the efficiency of human-vehicle interaction has a high value of research.The study content of this paper is as follows:Firstly,the development status of eye movement and human-machine interaction is studied.The application of eye-movement interaction and the driving distraction in the interaction between human and vehicle are analyzed.Then the user research,the drivers are classified to three kinds respectively,conservative,intermediate,radical;the needs of the user are collected and categorized.Then the prototype of the navigation system is designed,the semantics and information architecture of the eye movement interaction is designed,and the technical principle is analyzed.Finally,the eye movement experiment and the usability evaluation of the designed navigation system prototype arc carried out.The innovation of this paper is as follows:the eye-movement interaction semantics is designed,and the eye-movement interaction is applied to the vehicle as a new man-machine interaction method.The "human-centered" human-machine design method.The navigation system prototype is designed with the head-up display as the carrier.At the same time,the core function of the navigation system is optimized,which accords with the user's requirement and the using scenarios.The research of this paper can provide the reference value for the research of human-machine interaction of car navigation system.
