多用户协同手势下触摸点用户归属问题研究

Research on Ownership of User Points of Multi-User Collaborative Gesture

随着多点触摸交互技术的发展,大尺寸交互区下的操作是触摸屏未来发展的一个趋势,多用户协同手势的识别是支持其发展的一个关键技术;针对多用户协同手势识别中触摸点用户归属问题,提出区域划分、直接对象、主点作用域三种归类模式,避免了多用户触摸点之间的交叉影响,将触摸点区分到不同的用户手势中,为后续根据手势信息进行下一步的手势识别提供了可靠的依据;最后给出三个实例验证方法的有效性,并采用用户问答方式对其交互性和效率进行了统计和分析。

With the development of multi-touch interaction technology,the interactive operation under a large area touch-screen is a trend for future development.Multi-user collaborative gesture recognition is a key technology for its development.Three classified models were proposed,including zoning,direct object,the main point of scope,which could identify the ownership of the touch points before the multi-user collaboration gesture recognition.This method supplied a good solution for avoiding the cross-influence between multi-user touch points,and distinguishing the touch point to a different user gestures,which provided a reliable basis for the subsequent gesture recognition according to the information of gesture.Finally,three examples verified the effectiveness of the method,meanwhile,the statistic and analysis were made to its efficiency in the way of user questions and answers.
