Indexing Behavioral Decrements by Computerized Assessment of Stance

在许多职业和环境情况下，个人可能会受到可能对主观幸福感、生产力和业绩产生不利影响的条件的影响。这些条件包括更传统的“治疗”条件，如工作压力、热压力、药物和睡眠不足，以及在更现代的系统中获得的条件，如模拟器和虚拟现实系统。这一努力的目的是提供一个与人类中枢神经系统的整体状态和功能完整性有关的稳定基线行为的客观指标。这一指标显然与在工作场所安全和成功地执行定期受控活动有关，同时能够达到实验室的准确性。要监测的活动是视觉系统将感兴趣的对象成像到中心凹上的综合行为，这是人类的一种协调行为，可以被许多事物扰乱。这项研究的前提是，监测这一活动(测量眼睛/头部与所需位置的偏差)可以作为一个人执行无差错工作能力的功能状态的全局和敏感指标。为此，该项目将在实验上进行验证，然后生产一种高度便携的设备，用于测量个人的站姿控制。

Individuals in many occupations and environmental situations can be subjected to conditions that may have adverse effects on subjective well-being, productivity, and performance. These conditions include the more traditional "treatment" conditions, such as job stress, thermal stress, drugs, and sleep loss, as well as conditions obtaining in more modern systems such as simulators and virtual reality systems. The purpose of this effort is to provide an objective indicator of stable baseline behaviors related to the overall status and functional integrity of the human central nervous system. Such an index would have obvious relevance for the safe and successful execution of regularly controlled activities in the work-place and, at the same time, would be capable of achieving laboratory accuracy. The activity to be monitored is the integrated behavior of the visual system to image an object of interest on the fovea, a coordinated behavior in humans that can be disrupted by many things. The premise of this research is that monitoring this activity (measuring the deviation of the eye/head from the desired position) can be a global and sensitive index of the functional status of a person's ability to perform error-free work. To this end, this project will validate experimentally and then produce a highly portable device for the measurement of an individual's control of stance.
