车内三维交互手势可用性评价研究

Usability Evaluation of Three Dimensional Interactive Gesture

目的通过建立评价模型对手势进行评价,以此提高车内三维手势的可用性。方法研究三维手势的可用性基本理论及其在汽车中的应用现状,采用模糊综合评价法对车内三维手势的可用性进行评价,实现手势可用性的量化评价。通过对驾驶环境中的任务、用户、环境及用户参与等方面进行分析,提取可用性影响因素,经过删选合并确定评价指标,建立模糊综合评价模型。对车内音量调节功能的手势进行评价实践,通过对比评价结果,从备选手势集中确定最终手势。构建场景模拟实验,通过对比评价和实验两种方式对手势备选集的评价结果进行分析,证明评价模型的有效性。结论建立车内三维交互手势可用性评价指标体系和模型,对手势可用性进行量化评价,为车内手势的设计提供可参考的理论依据。

The evaluation model is used to improve the availability of 3D hand gesture by evaluating gestures. The availability theory of 3D gesture and its application in automobile are researched, and the fuzzy synthetic evaluation method is used to evaluate it and quantify the gesture availability. Through analysis of the driving environment tasks, us- ers, the environment and user participation, the useful factors are extracted, and a fuzzy comprehensive evaluation model is established after deleted and merged. Using the evaluation to assess the volume adjustment function of the car, the final gesture from the optional gesture set is determined by comparing the evaluation results and the effectiveness of the evalu- ation model is proved by simulation experiments. The model of 3D hand gesture usability evaluation is established, which can provide the theoretical basis for the design of the interior gesture through quantitative evaluation.
