Design Method Of Mobile Phone Riding Navigation Interface Guided By Visual Attention Mechanism

Mobile phone navigation plays a role that cannot be ignored in daily life.People already rely heavily on mobile phone navigation when traveling in traffic.It is inconvenient for users to operate mobile phones during riding,and they need to pay attention to road conditions and navigation information at the same time.Due to the limited distribution of human attention,the design of mobile phone navigation interface needs to be aimed at improving the efficiency of user attention and information acquisition.Therefore,it is of practical significance and research value to study the attention distribution of users using cycling navigation and the mobile phone cycling navigation interface in the state of cycling.Based on the SEEV attention model,this dissertation explores the user’s attention distribution during cycling,and explores the design direction of the cycling navigation interface for the purpose of optimizing user attention distribution.According to the environmental characteristics of cycling and user operation scenarios,a SECV attention prediction model that is more suitable for cycling scenarios is proposed,and it is revealed from the four dimensions of visual salience,expectation,complexity,and value that affect cycling users’ perception of the cycling navigation interface.The key factors of attention distribution,and put forward specific quantitative basis for the four factors.On this basis,carry out the user’s riding scene attention distribution eye-tracking experiment,and collect the user’s eye-movement data.The ITTI algorithm is used to calculate the visual salience of the sample;the expected and value factors are quantified according to the score of the user’s subjective score;the user’s attentiondistribution is used as the dependent variable,and fixation count is used as the quantification basis;MATLAB software is used to fit the SECV attention prediction model,and the relational expression of the model is obtained and the accuracy of the model is tested.According to the research results of the model,the design strategy of the mobile phone navigation interface is proposed.Finally,the scientificity and effectiveness of the proposed method are verified through design practice.
