| In the context of the era of consumer and service upgrades,the user experience gradually occupies the core position in the Internet field.For the portal of information communication as the core function,the user experience has become an important support for ensuring the user's visit and the information dissemination effect.With the user to share,information aggregation is characterized by the rapid development of web2.0 era,information overload has become a constraint information dissemination effect,resulting in portal function paralysis,affecting the biggest obstacle to its user experience.In order to alleviate the impact of information overload on portal user experience,this study is based on the theory of visual perception,from the perspective of web visual depn,through two experimental research,on the one hand to explore the visual complexity of the portal user experience,On the other hand to explore the optimization of the portal user experience an effective program.In the first experiment,through the combination of objective assessment and subjective investigation,the existing portal website was selected as the experimental material.The visual complexity(high and low)was used as the independent variable and the user experience as the dependent variable.By collecting 20 subjects using different visual The subjective mood experience,the subjective usability evaluation,the avoidance attitude,the number of gaze,the gaze time,the skin conductance and the heart rate as the response index of the user experience are carried out in the visual search task.The user experience level is evaluated by the direct evaluation method.Examines the impact of visual complexity on the site user experience with the same page size.The second experiment based on the first experimental results,according to the experimental needs of the depn site materials,set the information capacity of the high visual complexity of the site as a control group,respectively,using tiled and cascading structural depn to expand the area of the page to reduce the visual the complexity.The two-factor mixed depn,the web structure(control group,tiled,cascading)for the group of independent variables,information capacity(high,low)for the group of independent variables,through the collection of high and low information capacity of the 20 Subjects in the use of different structures to depn the site when the user experience indicators,in the case of web content unchanged,to expand the page area to reduce,the visual complexity of the user experience in optimizing the effectiveness of the page,as well as the page structure and information The impact of capacity on this optimization scenario.And finally draw the following conclusions:(1)Web page visual complexity is an important factor affecting the user experience of the portal.Compared to the low visual complexity of the site,users use low vision complexity of the site when the visual search more efficient,low level of cognitive load,the user's attitude is more positive,better emotional experience,the corresponding level of user experience higher.(2)for the web page with high visual complexity of the site to expand the area of the page to reduce the visual complexity can be used as an optimized portal user experience an effective program.In the case of the same web content,regardless of the use of tiled or stacked structure depn to expand the page area,reduce the visual complexity of the page,in the user experience optimization has a pnificant effect.(3)Web page structure and web page information capacity control portal user experience optimization effect,for different information capacity of the page,using a different web structure depn,in optimizing the user experience is also different.For low information capacity pages,tiled and cascading structural depn can effectively optimize the portal user experience;and for high information capacity of the page,cascading in the optimization of the portal user experience is better than the tiled structure. |
