我们分析了如何提高空中非仪表指向的指向性能，以达到与鼠标相同的吞吐量。使用筷子指向可以实现最高的平均吞吐量，为 3.89i?źbps。与使用手指指向屏幕相比，这是一个重大改进。研究人员探讨了筷子和手指操作之间吞吐量差距的两个潜在原因：人类手指的自然弯曲以及手指向设备弯曲时出现的跟踪问题。然而，这些因素似乎都没有显着影响吞吐量。因此，其他尚未探索的因素一定是原因。最后，还探讨了不可靠的点击检测的影响，因为这也会影响未检测的性能，并且发现具有线性效应。
We present an analysis of how pointing performance in in-air un-instrumented pointing can be improved, towards throughput equal to the mouse. Pointing using a chopstick is found to achieve the highest average throughput, with 3.89i?źbps. This is a substantial improvement over using the finger to point at the screen. Two potential reasons for the throughput gap between chopstick and finger operation were explored: the natural curvature of human fingers and tracking issues that occurs when fingers bend toward the device. Yet, neither one of these factors seems to significantly affect throughput. Thus other, yet unexplored factors must be the cause. Lastly, the effect of unreliable click detection was also explored, as this also affects un-instrumented performance, and was found to have a linear effect.
