地图个性化认知是地图设计与地图可用性研究中的重要问题。本文以二维电子地图为例,针对不同样式地图原型对特定用户的认知适合度问题进行研究。以交叉组合设计的4种地图原型为素材进行单因素组内眼动试验设计,采用TobIiX120眼动仪获取目标点周围兴趣区内的首次进入时间、首次注视时间和首次鼠标点击时间等眼动(行为)参数,通过描述统计、方差分析等多元数理统计分析进行量化计算,发现地图样式对首次进入时间、首次注视时间、首次鼠标点击时间均有显著影响,说明用户对不同样式地图的认知效果在认知敏感程度、注意程度、信息加工速度方面都存在一定差异。而后,本文进一步寻求认知心理学理论依据,并绘制眼动热点图、统计均值图、折线图、雷达图等可视化图形,将上述结论进行直观表示。本文的研究工作表明,不同地图的认知效果因人而异,地图设计必须考虑用户的个性化认知特点。
Map personalized cognition is an important question in map design and map usability evaluation. In this paper, different electronic map on computer screen was designed to match designated user. During this process, eye movement experiment and quantitative evaluating methods were conducted to explore the different cognition effect and personalized cognition suitability. At first, four simplified types of map prototypes were produced with some similarity, which supported personalized cognition suitability evaluation and eye movement experiment after. Then an eye movement experiment in subjects who belonged to the designated user class was conducted by eye tracker Tobii X120. The indexes such as time to first fixation, first fixation duration and time to first mouse click in AOI around aim point were recorded by the eye tracker automatically. In the following, multivariate statistical analysis methods were used to obtain the significant results, including the descriptive statistical analysis, the analysis of variance and the simple effect inspection. Furthermore, the visualized heat maps of users* eye movement paths were generated and overlaid at the same time. The quantitative analysis results in eye movement experiment show there are significant difference in the eye movement and mouse action indexes between each map, which explain the different cognition susceptibility, attention and information processing speed in deep brain thinking level. And the personalized cognition suitability on map comes from the age, gender, hobby, even the familiarity degree to handle map. So, eventually, some cognitive psychology theories are referred to. Personalized cognition characters of map user are emphasized by this research to improve map design quality and spatial information transmission efficiency.
