Experimental Evaluation of Pen-based Chinese Word Processing Usability

摘要

An evaluation experiment was conducted to compare four interface styles: Hanwang Fixed Window, Translucent Mobile Single Window, Translucent Mobile Double Window, and No Window. Subjects tested the four styles for typical word process task, including input, insert, exchange on a free style text edit system. The results show that the TMDW was the most efficient and the most accurate mode, in terms of total editing time and accuracy rate. Also experimental data exhibited that NW is the most nature style, in terms of the subjects' preferences. This experiment confirmed that a proper employment of interface style could improve the interactive efficiency of text editing systems. Our tests for the first time give statistical support to the view that the nature gesture is useful for editing interface for word process systems.
