多种手势对应同一语义的柔性映射交互算法的研究

针对智能交互界面中手势识别错误导致交互界面变化错误和手势不识别两个基本问题,本文设计并实现了基于手势交互的智能教学界面,该系统可以通过获取教师的手势信息与教师进行交互.主要创新点在于提出了多种手势对应同一语义的柔性映射交互算法.本文选取了14种自然交互手势,分析了对应同一语义的多种手势之间的共同特征.实验结果显示,该算法能够有效降低用户负荷.该算法已经用于一个基于手势交互的智能教学系统界面中.国家重点研发计划(No.2018YFB1004901)国家自然科学基金(No.61472163,No.61603151)山东省重点研发计划(No.2017GGX10146

Determination of the number of ψ(3686) events taken at BESIII

The number of ψ(3686) events collected by the BESIII detector during the 2021 run period is determined to be (2259.3±11.1)×106 by counting inclusive ψ(3686) hadronic events. The uncertainty is systematic and the statistical uncertainty is negligible. Meanwhile, the numbers of ψ(3686) events collected during the 2009 and 2012 run periods are updated to be (107.7±0.6)×106 and (345.4±2.6)×106, respectively. Both numbers are consistent with the previous measurements within one standard deviation. The total number of ψ(3686) events in the three data samples is (2712.4±14.3)×10^
