自适应气泡光标——基于用户的点击增强技术

The Adaptive Bubble Cursor—Pointing Augmented Technique Based on Users' Operation

本研究选取了气泡光标这种典型的点击增强技术作为研究对象,从用户操作习惯和特点出发,提出基于频次算法的和基于时间算法的自适应气泡光标,并试图通过实验研究来探索这两款自适应气泡光标的影响作用。结果显示:(1)基于频次算法的和基于时间算法的自适应气泡光标在操作绩效和主观评价上均显著优于气泡光标;(2)两款自适应气泡光标在操作绩效和主观评价上无显著差异。本研究的结果为点击增强技术的设计优化提供了新的设计思路。

Mouse pointing is a basic operation in the graphical user interface, In order to improve the users＇ pointing pertormance, me current study developed two kinds of adaptive cursors based on the bubble cursor （Grossman ＆ Balakrishnan, 2005, April）, which is the currently the fastest-known general pointing technique. Moreover, we carried out an empirical experiment to verify the effect of these two adaptive cursors （compared with the bubble cursor）. The current study consists of two parts. The first one describes the development of the two adaptive cursors. The effective width of the new cursors could be changed dynamically according to the different adaptive algorithm, as shown in Fig. 2. This study adopted two typical adaptive algorithms： one chose the most used item as the adaptive item, and the other chose the most recent-used item. Based on these two adaptive algorithms, we respectively named the new cursors the frequency adaptive bubble cursor and the time adaptive bubble cursor.
