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.This proposal aims to contribute to increasingly important research on fundamental human processes of body schema and body image, particularly as they change over time. 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, (ii) develop visualizations that correlate to changing user states, initially in VR avatars for range of movement studies in seniors, (iii) develop an interface that enables user annotations of body image data, (iv) develop methods for accurate repeatability of capturing user state data, (v) visualize aggregation of variable timeframes for later analysis of longitudinal data of users' psychophysiological states and (vi) develop methods of empirical assessment. 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过程，这些过程负责典型的无意识过程，如姿势和运动。身体形象指的是我们对自己身体的态度和信念，这种态度和信念会随着时间的推移而改变，或者当我们面对残疾或疾病时。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，提供有关用户心理生理状态的重要信息。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，特别是随着时间的推移，它们会发生变化。我们建议：(i)通过抽象和建模各自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，（ii）开发与不断变化的用户状态相关的可视化，最初是在用于老年人一系列运动研究的VR化身中，（iii）开发使用户能够注释身体形象数据的界面。（iv）开发获取用户状态数据的精确可重复性方法；(v)可视化可变时间框架的聚合，以便以后分析用户心理生理状态的纵向数据；（vi）开发经验评估方法。这项研究的长期目标有两个方面：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。
