The Study Of Design Of In-vehicle Information System User Interface Based On Unconscious Cognitive Processing

The computer-related technology has been widely applied to certain functional parts of the industrial products to enhance their capacity of massive data exchange and processing.The in-vehicle information system is standard equipment for most new cars.The safety issue has become a major concern since the human-vehicle interaction system is highly sensitive especially when it is under the high speed movement.With the implanting of the information system,the complexity of interaction-related tasks has reached a high level.The human-vehicle interface evolves to the Multi-Touch screens instead of the mechanical instruments.The increasing amounts and dimensions of real-time data in vehicle leads to a cognitively demanding situation for drivers.By comparing the different implicit modes of information processing,the analysis was done to find out the unconscious cognitive processing which can perceive and manipulate the environment stimulation and eventually drive human conduct the explicit behavior.And this unconscious processing cause subjects almost no cognitive resources consuming and lead to reliable and effective reaction which is practical for the interaction tasks since the this is the usability and user experience target of a interaction system.Analysis was done to establish the interface design guidelines based on the strategy of optimizing of various components in a interaction interface which is integral to the in-vehicle information system to ensure that drivers can focus on the primary driving tasks and reduce the distraction effect which can be achieved caused by the in-vehicle secondary tasks such as the interaction with the in-vehicle information system by using human’s unconscious automatic processing.Finally,the design project of a in-vehicle electronic instrument interface was done,to verified the feasibility of interface design strategy based on guiding user to interaction with the information system using human’s unconscious automatic processing.The project was done by following the procedure of software user interface design including user needs study based on driving situation,user satisfaction study(the Likert 7-point scale),prototype design and analysis of survey data(Z-score converting,Homogeneity of variance test).Through the analysis and experiment,this study forms the theoretical frameworks of in-vehicle information system interface design to guide the user applying unconscious cognitive processing which can result in an effective and reliable interaction system and optimize the usability and user experience.
