分析了触控交互技术在移动手持设备及可穿戴设备应用的应用现状及存在的问题；基于交互动作的时间连续性及空间连续性，提出了将触控交互动作的接触面轨迹与空间轨迹相结合，同时具有空中手势及触控手势的特性及优点的混合手势输入方法；基于连续交互空间的概念，将混合交互手势，空中手势、表面触控手势进行统一，建立了包括空中层、表面层、混合层的连续交互空间分层处理模型；给出了统一的信息数据定义及数转换流程；构建了通用性的手势识别框架，并对轨迹切分方法及手势分类识别方法进行了阐述.最后设计了应用实例，通过实验，对混合交互手势的可用性及连续空间分层处理模型的可行性进行了验证.实验表明，混合手势输入方式同时兼具了表面触控输入及空中手势输入的优点，在兼顾识别效率的同时，具有较好的空间自由度.

Hybrid Gesture Interaction Model in the Continuous Interaction Space

Analyzed the application and existing problems of touch interaction for mobile handsets and wearable device. Based on time continuity and space continuity of interactive action, we proposed the hybrid gesture input method with characteristic and advantages of air gesture and touch gestures, which combine the contact trajectory and in-air trajectory of the interactive action. Based on the concept of continuous interaction space, we unified hybrid interaction gestures, air gestures, surface touch gestures, and established a continuous interaction space hierarchical processing model including the air layer, surface layer and hybrid layer. Then expounded the definition information data and the transformation process. The general gesture recognition framework was constructed. Then, the trajectory segmentation method and gestures classification methods were introduced in detail. Finally, we design the application instance, and verified availability of the hybrid interaction gestures and feasibility of the continuous interaction space hierarchical processing model. Experiments showed that, the Hybrid Gesture Interaction Model got the advantages of both air gesture and touch gestures, had good recognition efficiency and better spatial freedom.
