基于现场评价的智能手机触摸手势工效学研究

Research on touch gesture ergonomics of smart phone based on field-evaluation

为了提高触摸手势识别准确率,针对智能手机触摸手势工效学参数进行现场评价。首先,基于非理性用户模型提出了触摸手势现场评价因素框架;其次,设计现场评价实验,收集新手用户和经验用户在室内静坐、户外行走和公交静坐3种情境下的测试数据,得出基于使用情境修正的手势工效学参数,优化了手机触摸性能。研究表明,现场环境中用户运动状态和情绪警觉水平影响手机使用触摸性能,需采用现场情境测试修正触摸工效学参数,以提高手势识别准确率。

This paper aims to enhance the accuracy of touch gesture recognition by building a field-evaluation method for touch gesture ergonomics parameters of mobile phones. First, a touch gesture test factors framework is proposed based on irrational user model. Second, an field test experiment for touch gestures ergonomics factors is designed, in which field test data of novice users and experienced users in three different scenarios, sitting quietly indoors, walking outdoors and sitting quietly in a bus, are collected. The result shows that the state of motion and emotional alert level are factors affecting the gestures ergonomics. The parameters need to be optimized by field test to improve recognition accuracy.
