面向任务的驾车导航POI分级体系构建的研究

POI分级体系的构建是POI自适应表达的关键。文中从影响驾车导航的因素出发,对驾车导航任务进行归纳,然后针对不同的导航任务,采用定性定量相结合的方式,通过问卷调查、焦点小组法以及数理统计的方法,构建对应不同导航任务的POI分级体系,满足驾车导航POI自适应表达的需要。

Establishing a task-oriented driving navigation POI classification system

The establishment of POI classification system is the key to POI self-adaptive expression.This paper summarizes the driving navigation tasks based on the influence elements of driving navigation.Then a POI classification system is established through both quantitative and qualitative surveys as to the different navigation tasks.The questionnaire method,focus group interviews and mathematical statistics are used to establish this POI classification system to fulfill the POI self-adaptive expression' s needs of driving navigation.
