Interacting with Human Physiology

这笔资金使PI能够探索一个意想不到的机会，这个机会是在他目前的奖项（0414754）资助的题为“与人类生理学的相互作用”的研究中发现的。新的工作将在一个及时和重要的新方向上扩展项目的范围。皮肤电反应（Galvanic Skin Response， GSR）是人机交互过程中最敏感、最特异的应力定量生理感知模式。在现有的资助下，PI已经证明了轨道周围和轨道上的传感也可以量化应力并用于交互实验。更重要的是，眶周和眶上传感可以在远距离（通过热成像）和易于接近的组织区域（面部）上进行。这些都是巨大的优势，因为用户不受干扰。最近，PI已经确定了上颌区域的一个通道，该通道与GSR测量的手掌通道具有相同的胆碱能性质，并且已经开始发展一个综合理论，该理论考虑了所有面部通道（眶周，眶上和上颌），并根据GSR对它们进行量化，新出现的结果是“面部GSR通道-距离”。这是一个潜在的突破，因为它确定了一种无接触的测量方法，可以证明它在心理生理学研究中表现得和最佳接触法（GSR）一样好。这笔资金将使PI能够解决最初仍未解决的技术挑战，这些挑战涉及由于分割和跟踪中残留的缺陷而导致的面部信号退化。新工作的主要部分将集中在交互性问题的探索上，其中集成方法将与传统的GSR技术进行比较，重点是关键任务软件。更广泛的影响：这笔资金的一部分将用于组织第一次关于“生理监测24/7及其交互潜力”的研讨会，该研讨会将于8月底在法国里昂举行的IEEE医学和生物学工程会议上举行。里昂大学为这次活动提供了一间会议室，并确定了一些宿舍房间，可以用来容纳研究生参与者，这将大大降低NSF的成本。

This is funding to enable the PI to explore an unexpected opportunity that has come to light during research funded under his current award (0414754) entitled "Interacting with Human Physiology." The new work will extend the scope of the project in a timely and important new direction. GSR (Galvanic Skin Response) is the most sensitive and specific physiological sensing mode for stress quantification during human-computer interaction. Under the existing grant, the PI has demonstrated that periorbital and supraorbital sensing can also quantify stress and be used in interactivity experiments. More importantly, periorbital and supraorbital sensing can be carried out at a distance (via thermal imaging) and on an easily accessible tissue area (the face). These are tremendous advantages, because the user is left undisturbed. Recently, the PI has identified a channel on the maxillary area, which is of the same cholinergic nature as the palm channel that GSR measures, and has begun to develop a comprehensive theory that accounts for all facial channels (periorbital, supraorbital, and maxillary) and quantifies them against GSR, the emerging result being a "facial GSR channel-at-a-distance." This is a potential breakthrough, as it identifies a contact-free measurement method that can provably perform as well as the best contact method (GSR) in psycho-physiological studies. This funding will allow the PI to address initially technical challenges that remain unsolved, which relate to degradation of the facial signals due to residual imperfections in segmentation and tracking. The major portion of the new effort will concentrate on exploration of interactivity issues where the integrated methodology will be compared vis-a-vis the traditional GSR technology, with a focus on mission critical software. Broader Impacts: A portion of this funding will provide for the organization of the first workshop of its kind on "Physiological Monitoring 24/7 and its Interactivity Potential" that will be hosted in late August at the IEEE Engineering in Medicine and Biology Conference to be held in Lyon, France. The University of Lyon has kindly provided a conference room for this event and identified a few dorm rooms that can be used to house graduate student participants, which will greatly reduce the cost to NSF.
