Recent research in the emerging field of embodied cognition demonstrates the mutual importance of***understanding the extent to which technologies affect our physical/physiological factors, and how our***assumptions about our bodies affect the ways we design technology. Thus, it is increasingly important to study***the fundamental processes of body schemas and body images. A body schema comprises the collection of***processes that are responsible for typically non-conscious processes such as posture and movement. A body***image refers to attitudes and beliefs we have about our body, which change over time, or when we face***disability or disease. Body schema and body image function as continuous, mutually influential processes that***provide important information about a user's psychophysiological state.******The focus of proposed body image/body schema research will be on immersive VR. Research in body ownership of VR avatars has led to important findings regarding visual, motor and tactile phenomena, as well as the role of time in how VR users gain a sense of “ownership” of their VR avatars. In essence, this tells us important information about body schema, but far less about body image. Moreover, while this research includes the adoption or ownership of non-human body parts, such as tails, it nevertheless assumes a healthy, normative body. However, certain conditions such as chronic and phantom pain are known to profoundly disturb body image and body schema. Moreover, while VR has been shown to be a form of pain alleviation, the mechanism that may explain this effect is still in its infancy, as are varied outcomes about how long this effect may persist after VR exposure. These are some examples of why it is important to gain a better understanding of how users gain an embodied sense of a VR avatar from a first person perspective - a perspective that includes body image.******This proposal aims to contribute to increasingly important research on fundamental human processes of body schema and body image. We propose to: ***(i) investigate computation of body schema and body image by abstracting and modeling relevant correlates of each, (ii) identify relationships of body schema and image that together indicate variable psychophysiological user states, (iii) develop visualizations that correlate to changing user states, initially in VR avatars for range-of-movement studies in seniors, (iv) develop an interface that enables user annotations of body image data, (v) develop methods for accurate repeatability of capturing user state data, (vi) visualize aggregation of variable time frames for later analysis of longitudinal data of users. ******The long-term objective of this research is two-fold: ***1. To identify the theoretical underpinnings and formalisms necessary to devise computational models of variable body schema and image data. ***2. To develop methods of assessment to provide empirical evidence of effectiveness.

最近在具身认知这一新兴领域的研究表明，理解技术对我们身体/生理因素的影响程度，以及我们对身体的假设如何影响我们设计技术的方式，两者都很重要。因此，研究身体图式和身体意象的基本过程变得越来越重要。身体图式包括一系列负责典型的无意识过程（如姿势和动作）的过程。body image指的是我们对自己身体的态度和信念，这些态度和信念会随着时间的推移而改变，或者当我们面临残疾或疾病时。身体图式和身体形象作为连续的、相互影响的过程发挥作用，这些过程***提供了关于用户心理生理状态的重要信息。******提议的身体形象/身体图式研究的重点将放在沉浸式VR上。对虚拟现实化身身体所有权的研究已经导致了关于视觉，运动和触觉现象的重要发现，以及时间在虚拟现实用户如何获得虚拟现实化身“所有权”感中的作用。从本质上讲，这告诉了我们关于身体图式的重要信息，但关于身体形象的信息却少得多。此外，虽然这项研究包括采用或拥有非人类身体部位，如尾巴，但它仍然假设一个健康、规范的身体。然而，某些情况，如慢性疼痛和幻痛，会严重扰乱身体形象和身体图式。此外，虽然VR已被证明是一种缓解疼痛的形式，但解释这种效果的机制仍处于起步阶段，就像VR暴露后这种效果持续多久的各种结果一样。这些例子说明了为什么更好地理解用户如何从第一人称视角（包括身体形象的视角）获得虚拟现实化身的体现感很重要。******本提案旨在促进对人体图式和身体形象的基本人类过程的日益重要的研究。我们建议：***(i)通过抽象和建模身体图式和身体形象的相关关系来研究身体图式和身体形象的计算，（ii）确定共同表明可变心理生理用户状态的身体图式和形象的关系，（iii）开发与不断变化的用户状态相关的可视化，最初用于老年人运动范围研究的VR化身，（iv）开发使用户能够注释身体形象数据的界面。(v)发展可准确重复捕获用户状态数据的方法；（vi）将可变时间框架的聚合可视化，以便以后分析用户的纵向数据。******本研究的长期目标是双重的：***1。确定设计可变身体图式和图像数据计算模型所需的理论基础和形式。* * * 2。制定评估方法，提供有效性的经验证据。
