| 摘要: |
| 通过文献调研和用户问卷调查,探查现存的笔手势的特征和分类,分析探讨良好、易学的笔手势的应当具备的特征;然后,从命令与笔手势联结是否紧密的角度提出意义性笔手势的概念,并将意义性笔手势分为3类:指示性笔手势、实物隐喻笔手势和文化约定笔手势;最后,通过相应的学习实验来验证根据本研究的分类所设计的意义性笔手势在易学性方面的优势.结果表明,意义性笔手势比其他非意义性笔手势更易学、易用.此结果可以用心理学中双重编码理论进行解释,同时可以作为设计笔手势的基本指导原则之一. |

| Abstract: |
| In this paper, the characteristics and classifications of current used pen gestures are investigated. And characteristics with “good” and learnable pen gestures are analyzed through literatures and a questionnaire. Afterwards, the concept of “meaningful pen gesture” is presented according to the consideration whether there are tight relationships between a pen gesture and the corresponding command existing. And the meaningful pen gesture is divided into three categories: directive, object-metaphor and conventional. At last, an experiment is performed to validate the advantage of the meaningful pen gestures designed in this paper. The results show that the meaningful pen gestures are easier to learn and to use. These results can be interpreted by the dual-coding theory, and can be one of the basic guidelines for designing pen gestures. |
