可用性的主观评价方法成本高、耗时长，而且由于主观的观点，有时比客观评价方法的数据更不可靠。另一方面，传统的客观评价方法是有用和可靠的，但成本昂贵。此外，这种方法通常不可行，因为获取许多电气产品的操作日志可能很困难。为了克服目前的局限性，我们提出了一种客观的可用性评估方法，该方法适用于各种类型的界面，例如实际电子产品或触摸屏上的再现界面。我们提出的方法是通过图像处理提取用户在操作过程中记录的指尖运动，然后基于可测量参数评估可用性。实验结果表明，在传统的客观评价方法无法识别可用性问题的情况下，该方法能够有效地识别可用性问题。
The subjective evaluation method of usability is costly and time-consuming, and is sometimes more unreliable data than objective evaluation method because of the subjective view. On the other hand, the objective evaluation method is traditionally useful and reliable, but expensive. Further, this method is often not feasible, as acquiring the operation logs of many electrical products can be difficult. To overcome current limitations, we propose an objective evaluation method of usability that is applicable to various types of interfaces, such as those of actual electrical products or reproduced interfaces on a touch screen. Our proposed method involves extracting recorded fingertip movements of users during operation via image processing and then evaluating usability based on measurable parameters. Experimental results demonstrate that the proposed method was able to identify problems with usability even when the traditional objective evaluation method could not.
