Interacting with Human Physiology

这笔资金是为了使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)题为“与人类生理学相互作用”的研究中被发现的。新的工作将在一个及时和重要的新方向上扩大项目的范围。皮肤电流反应(Galvanic Skin Response，GSR)是人机交互过程中最敏感、最特异的应激反应生理感知模式。在现有的拨款下，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相互作用实验。更重要的是，眼眶周围和眶上的感知可以在很远的距离(通过热成像)和在容易接近的组织区域(面部)进行。这些都是巨大的优势，因为用户不受干扰。最近，PI在上颌区确定了一条与GSR测量的手掌经络相同的胆碱能经络，并开始发展一套全面的理论，对所有面部经络(眶周围、眶上和上颌)进行计算，并将它们与GSR进行量化，新出现的结果是“面部GSR经络-a-a距离”。这是一个潜在的突破，因为它确定了一种非接触式测量方法，可以在心理生理研究中与最佳接触法(GSR)一样有效。这笔资金将使PI能够解决最初仍未解决的技术挑战，这些挑战与由于分割和跟踪中的残留缺陷而导致的面部信号退化有关。新工作的主要部分将集中于探索互动问题，将综合方法与传统的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“24/7全天候生理监测及其互动潜力”研讨会，该研讨会将于8月下旬在法国里昂举行的IEEE医学和生物学工程会议上主办。里昂大学为这次活动提供了一间会议室，并确定了几个可用于容纳研究生参与者的宿舍，这将极大地降低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.
