的系统 [7] , 从操作系统层面研究指笔混合交互问题将成为本文今后的一个主要研究方向. (2) POMDP 在构建模型
时具有很优秀的表达力, 其近似求解算法很多, 不同的求解方法的适应场景也有所差异, 但本文仅以 PBVI 算法为
例进行了展示, 并未就哪种求解算法更适合意图提取方法进行探讨. (3) 本文的实验任务虽然从任务绩效上都达到
了预期目标, 但应用本文方法完成任务 1 的点击功能区次数偏高, 这是因为本文方法和传统方法理论上应该具有
相同的点击次数, 但被试对本文方法的熟练程度不如传统方法, 容易出现失误而重复操作. 同时实验中针对 6 种常
用图形对象的 4 种常用任务取得好的效果, 但在未来更大规模的实验中可进一步扩展操作对象和任务类型.
