【摘要】：失智症俗称老年痴呆症,常见于老年期的一种原发性退行性脑病。该病是一种持续性高级神经功能活动障碍,即在没有意识障碍的状态下,思维、记忆、分析能力、视空间辨认、情绪等方面的障碍,严重影响了病人的日常生活。其患病率随年龄的增长而增加。电脑游戏训练是老年人的一种认知训练方式。本研究基于多媒体技术,并以MSP430单片机为平台开发设计一款互动式的嵌入式游戏评估系统,即Fun Cube,包括硬件和配套软件。本论文在Sifteo Cube的基础上重新规划了系统架构。对使用Sifteo Cube过程中发现的诸多问题,在本互动游戏平台的开发中一一消除,并制作出全新的、符合我们研究场景的互动游戏装置。该游戏装置突破了颗数、荧幕等诸多限制,更加适合老年人应用。该系统由三部分组成:(1)互动装置:这部分是人机界面系统,负责收集测试者的测试数据;(2)数据管理器:负责游戏的管理和测试数据的存储;(3)反馈系统:测试者的数据结果将作为个人档案上传至服务器,医生可借此了解测试者的操作情况,及早发现失智症的高危人群。根据传输要求以及传输的便捷性,我们对无线通信模块(用于Fun Cubes之间以及Fun Cubes与服务器之间数据信息的传输)做了相应的改进。主要以RS-232C(UART)通信协定为主,采用的是2.4G RF进行数据传输,重新定义了无线传输协议、传输命令以及封包格式架构。系统完成后,为检测本系统的性能和效果,我们进行了四个实验:(1)Fun Cubes编号(ID)测试;(2)电磁感应测试;(3)游戏测试;(4)科技接受度(TAM)测试。经实验验证:12颗Fun Cubes的编号唯一;电磁感应性能达到要求;通过游戏得分状况可基本区分出失智症和非失智症人群;在科技接受程度方面,测试者对我们的各项游戏训练系统都给予了很高的评分。
[Abstract]:Dementia, commonly known as Alzheimer's disease, is a primary degenerative encephalopathy in the elderly. The disease is a kind of persistent high neurologic dysfunction, that is, the disorder of thinking, memory, analysis, visual space recognition, emotion and so on, has seriously affected the patients' daily life. The prevalence rate increases with age. Computer game training is a cognitive training method for the elderly. Based on multimedia technology and MSP430 single chip microcomputer, an interactive embedded game evaluation system, Fun Cube, is developed, including hardware and supporting software. On the basis of Sifteo Cube, this paper redesigns the system architecture. Many problems found in the process of using Sifteo Cube are eliminated one by one in the development of this interactive game platform, and a completely new interactive game device is made, which conforms to the scene of our research. The game device breaks through the number, screen and many other restrictions, more suitable for the elderly. The system is composed of three parts: the interaction device is composed of three parts: this part is a man-machine interface system, Data Manager: responsible for game management and storage of test data feedback system: the testers' data results will be uploaded to the server as a personal file. This is a way for doctors to identify individuals at high risk of dementia early on. According to the requirement of transmission and the convenience of transmission, we improve the wireless communication module (used for data transmission between Fun Cubes and Fun Cubes and server). The main communication protocol is RS-232C UART, which uses 2.4G RF to transmit data. The wireless transmission protocol, transmission command and packet format architecture are redefined. After the completion of the system, in order to test the performance and effect of the system, we carried out four experiments: 1: 1 / Fun Cubes (ID / IDN) test (/ 2) electromagnetic induction test (/ 3)) game test / game test (/ 4) / Tam) test. The experiments show that the number of 12 Fun Cubes is unique; the electromagnetic induction performance meets the requirements; the score of the game can basically distinguish the retarded from the non-retarded; in terms of the acceptance of science and technology, The testers rated our game training systems very well.
