摘要

注视辅助交互通常用于标准桌面设置。当与大型显示器交互时,随着诸如情境性损伤等新场景的出现,使用基于凝视的多模态输入比其他输入更方便。然而,基于注视的多模态输入与触摸和鼠标输入相比如何是未知的。在符合ISO 9241-9的Fitts定律实验中,我们比较了凝视+脚的多模态输入与触摸和鼠标输入在大型显示器上的不同。通过对23名参与者的研究,我们发现凝视输入的吞吐量最低(2.33比特/秒),运动时间最高(1.176秒)。此外,虽然触摸输入涉及最大的物理运动,但其吞吐量最高(5.49 bits/s),运动时间最短(0.623 s),是最受欢迎的输入方式。

A Fitts' law evaluation of gaze input on large displays compared to touch and mouse inputs
Gaze-assisted interaction has commonly been used in a standard desktop setting. When interacting with large displays, as new scenarios like situationally-induced impairments emerge, it is more convenient to use the gaze-based multi-modal input than other inputs. However, it is unknown as to how the gaze-based multi-modal input compares to touch and mouse inputs. We compared gaze+foot multi-modal input to touch and mouse inputs on a large display in a Fitts' Law experiment that conforms to ISO 9241-9. From a study involving 23 participants, we found that the gaze input has the lowest throughput (2.33 bits/s), and the highest movement time (1.176 s) of the three inputs. In addition, though touch input involves maximum physical movements, it achieved the highest throughput (5.49 bits/s), the least movement time (0.623 s), and was the most preferred input.
