Post-WIMP环境下笔式交互范式的研究

提出了一种在Post-WIMP环境下的笔式交互范式：PIBG．PIBG范式采用纸笔隐喻，与WIMP范式相比，承载应用信息的交互组件由Window变为Paper和Frame，用户的交互动作由鼠标的点击变为笔的手势．对PIBG范式中静态的界面形式和动态的交互手势进行了研究和设计．结合认知心理学，从信息呈现和交互方式两个方面对该范式的特点进行了阐述．利用GOMS模型，从界面呈现方式、手势的效率、用户满意度三个方面对该范式进行了心理学评估．从评估结果可以看出，PIBG范式通过模拟日常纸笔环境，利用用户原有的知识，可以明显地减轻认知负担，提高操作效率．

Research on a Pen-Based Interaction Paradigm in Post-WIMP Environment

Pen-based user interface is one of the main styles in Post-WIMP user interface. It is designed on the Pen-Paper metaphor that is analogous to the user's real working environment. It is a natural way for recording, communicating and capturing daily experiences. A new paradigm named PIBG is presented in this paper. In PIBG paradigm, P means physical object. Paper and Frame are main physical objects in PIBG paradigm. IB means icon and button. G means pen gesture. PIBG paradigm is based on Pen-Paper metaphor which is analogous to the user's real working environment. Compared with WIMP paradigm, the information presentation style and interaction style have changed. Widget containing application information is changed from Window to Paper and Frame, and user's action is changed from mouse pointing to pen gesture. The UI structure and interaction techniques of the paradigm are constructed in this paper. And the main characteristics of the paradigm are declared in detail from the viewpoint of Cognitive Psychology. At the end, the evaluation of PIBG paradigm is performed based on GOMS model. Evaluation results show that comparing with WIMP paradigm, PIBG paradigm can decrease user's cognitive load and improve user's interaction efficiency when user performs interaction tasks in pen-paper environment.
