【摘要】：本文主要研究把笔压力作为控制量引入到笔式交互技术中,用户对笔压力的控制能力,并根据实验结果设计了两个基于压力的交互技术:笔式交互中基于压力的可变焦小目标选择技术和引入压力的笔式文档滚动技术。第一:阐述了用户对笔压力的控制能力的研究。我们首先分析了在使用笔式交互的时候电子笔本身的压力分布情况,然后我们分析了当引入一些视觉反馈后,人们控制压力的能力情况,实验表明当引入视觉效果反馈的时候,实验者控制压力的能力显著提高;实验分析同时表明引入压力之后的笔式滑动任务依然可以用Steering law来描述。第二:我们设计了笔式交互中基于压力的可变焦小目标选择技术,该交互技术是把标准光标选择技术和可变焦目标选择技术结合在一起的,并利用压力作为离散变量去切换这两种模式。我们把该技术和Take Off技术、改进的区域光标技术进行对比,发现选择目标所用时间会随着目标宽度变化而变化。当目标宽度是2和4的时候,笔式交互中基于压力的可变焦小目标选择技术明显优于Take Off技术和改进的区域光标技术;当目标宽度是8的时候三者没有明显区别。在错误率上三种技术没有明显差别。第三:我们设计了引入压力的笔式文档滚动技术,该交互技术把压力作为滚动速率参数引入到笔式画线滚动技术中,实验者施加的压力越大滚动速率越大。实验结果表明当引入压力参数的时候,弧线形笔画滚动技术和直线形笔画滚动技术都优于没有引入压力参数时交互技术。第四:根据实验结果分析我们还提出一些关于笔压力技术的准则。首先,我们实验表明压力是有可以有效地提高笔式交互技术。其次,在设计压力交互技术的时候,可以把压力映射成离散变量或者压力的连续变量来实现基于压力的交互应用场景。
[Abstract]:This paper mainly studies the pen pressure as a control variable is introduced into the pen based interactive technology, the ability to control the user to pen pressure, and according to the experimental results to design two interactive technology based on pressure: pen interaction in the choice of document pressure pen technology and the introduction of pressure rolling technology based on zoom small target. The first: describes the user ability to control pen pressure. We first analyzed the electronic pen itself pressure distribution when using the pen, and then we analyzed when introducing some visual feedback, the ability of people to control the pressure, the experimental results show that when the introduction of visual feedback, the experimenter control pressure ability the analysis also showed that increased significantly; pen pressure after the introduction of sliding task can still use Steering law to describe. Second: we design the pen based on pressure The choice of technology zoom small target, the interaction is the standard cursor zoom selection technology and target selection technology together, and use pressure as discrete variables to switch between the two modes. We have the technology and Take Off technology, regional technical improvement of the cursor, select the target discovery time will vary with the target width changes. When the target width is 2 and 4 when the selection cursor technique is better than that of Take Off technology and improved pressure zoom small target based on pen interaction; when the target width is 8 when the three. No obvious difference in the error rate of three there was no significant difference between the third: technology. We design a pen type document rolling technology into pressure, the interactive technology to pressure as the roll rate parameter into the pen to draw a line of rolling technology, the experimenter applied pressure The rolling rate increases. The experimental results show that when introducing the pressure parameters of the curved and straight strokes strokes rolling rolling technology are higher than the introduction of pressure parameter interaction technology. Fourth: according to the experimental results, we also present some analysis about the pen pressure technology criterion. Firstly, our experiments show that there is a pressure can effectively improve the pen based interaction technology. Secondly, when the design pressure of interactive technology, the continuous variable pressure mapping into discrete variables or pressure to achieve interactive application scenarios based on pressure.
