光线指向技术通常被提倡作为一种让人们从几米远的地方与非常大的显示器进行交互的方式。我们对影响光线指向的两个因素感兴趣：特定技术的控制类型和视差。
因此，我们测试了四个光线指向的变体上的墙壁显示器，覆盖了大部分的用户的视野。任务包括横向和纵向目标定位和追踪。我们的研究结果表明，（a）基于“旋转控制”的技术更好地执行目标任务，（B）低视差的技术是最好的跟踪任务。我们还表明，基于角度（而不是线性距离）的Fitts定律分析更好地近似了人们的光线指向性能。
Ray-pointing techniques are often advocated as a way for people to interact with very large displays from several meters away. We are interested in two factors that can affect ray pointing: the particular technique's control type, and parallax.
Consequently, we tested four ray pointing variants on a wall display that covers a large part of the user's field of view. Tasks included horizontal and vertical targeting, and tracing. Our results show that (a) techniques based on 'rotational control' perform better for targeting tasks, and (b) techniques with low parallax are best for tracing tasks. We also show that a Fitts's law analysis based on angles (as opposed to linear distances) better approximates people's ray pointing performance.
