Recent advances in computer vision have made it possible for users to provide input to systems in far more natural ways than before. Camera-based tracking of a user's body allows systems to recognize hand gestures, body posture changes, and movements. While these are impressive capabilities, such systems have failed to make the leap to extensive industrial application. Previously, this lack of use could be attributed to the limitations of the technology. However, significant improvements have been made, and such systems are now capable of achieving recognition rates approaching those of traditional input devices. Therefore, we attribute the limited commercial use to shortfalls in two general areas of knowledge: (1) the lack of understanding of the true utility of these sensors with respect to human capabilities and needs; and (2) the composition of user interfaces required to facilitate their use.

计算机视觉的最新进展使用户能够以比以前更自然的方式向系统提供输入。对用户身体的基于相机的跟踪允许系统识别手势、身体姿势变化和移动。虽然这些都是令人印象深刻的能力，但这些系统未能实现广泛的工业应用。以前，这种缺乏使用可能归因于技术的局限性。然而，已经做出了显著的改进，并且这样的系统现在能够实现接近传统输入设备的识别率。因此，我们将有限的商业用途归因于两个一般知识领域的不足：（1）缺乏对这些传感器在人类能力和需求方面的真正效用的理解;以及（2）促进其使用所需的用户界面的组成。
