目前养老机构存在老年人日常生活活动能力（ADL）的评估方法准确性差、康复训练缺乏针对性和实践意义等现象，是影响老年人健康的突出问题。虚拟现实（VR）技术能实现ADL的量化评定，同时完成从经验型被动康复到科学型主动康复的模式转变，对促进人口健康老龄化具有积极而又十分重要的意义。课题组前期设计与开发了基于VR技术的运动训练模块，其结果显示基于VR技术的运动训练能有效提高老年人的认知功能、平衡能力，缓解疲劳状态。在此基础上，本课题旨在运用多学科交叉手段，搭建Avatar Kinect人机互动VR技术平台，设计符合养老机构老年人生活特性和康复需求的九大虚拟训练场景，开发多任务模式下的老年人ADL虚拟康复训练系统，并对老年人实施干预；构建ADL评估量化体系，对老年人ADL进行智能监测和评估。由此实现ADL的精确评估和有效康复，为养老机构老年人ADL康复训练和评估提供一个全新的思路。

The rehabilitation and evaluation of ADL in the long term care facilities still have problems such as poor accuracy of assessment methods, lack of targeted and practical rehabilitation training. Virtual reality (VR) technology can implement the quantitative evaluation of ADL, and the transformation from experiential passive rehabilitation to scientific active rehabilitation mode, which has a positive and very important significance for promoting the healthy aging of the population. The research group developed the sports training module based on VR technology, and the results showed that the sports training based on VR technology could effectively improve the cognitive function and balance of the elderly and alleviate the fatigue state. On this basis, this project aims to build the Avatar Kinect human-computer interactive VR technology platform, design nine virtual training scenes that meet the living characteristics and rehabilitation needs of the elderly in nursing institutions, develop the ADL virtual rehabilitation training system for the elderly under the multi-task mode, and implement the intervention for the elderly. A quantitative ADL evaluation system will be constructed to conduct intelligent monitoring and evaluation of ADL for the elderly. In this way, the accurate assessment and effective rehabilitation of ADL can be achieved, and a brand new idea can be provided for ADL rehabilitation training and evaluation of the elderly in nursing institutions.
