摘要
针对全身交互界面用户参与的定量评估问题,提出基于行为特征分析的研究思路。利用Openpose获得用户身体关键点坐标并提取行为特征,对比不同全身交互界面和任务模式中行为特征的显著差异,以及客观行为特征与主观感知参与度的关系。发现客观行为特征与主观感知参与度具有相关性和互补性。用户行为特征在某些属性上可以指示用户主观感知的参与程度,但两者不具有替代关系,对涉及全身交互的用户参与评估需同时从客观行为和主观认知两个层面开展。VR界面中用户总体平均速度和感知参与度均显著高于Kinect界面,VR界面在支持用户认知和行为层面的用户参与具有显着优势;任务模式影响交互行为的选择,相较于休闲模式,生存模式的交互行为更加精细。
To study the quantitative evaluation of user engagement in whole-body interface,a method based on the extraction of behavioral feature is proposed.Using Openpose to obtain the coordinates of user’s body key points and to extract behavioral feature,comparing behavioral feature between different whole-body interfaces and task modes.Found that the average speed of interaction and questionnaire data are consistent and complementary.User behavior feature can indicate some attributes of user engagement,but there is no substitute relationship.The evaluation of user engagement needs to be carried out from both behavioral and cognitive levels.Compared with the Kinect interface,the VR interface has significant advantages in supporting user engagement in both cognition and behavior.Task mode affects the choice of interaction behavior.Compared with leisure mode,the interaction behavior of survival mode is more refined.
