【摘要】 设计特定功能以替代或扩大人体部分机能,是现有许多产品重要的设计理念之一。长期使用这样的产品会导致人体机能逐渐地退化,甚至可能会危害人体健康。基于Inspiring技术的产品设计理念,是在设计产品预定功能的同时,考虑改善人体健康、激励人体潜能。Inspiring技术强调与现有产品的充分结合,具有广阔的应用前景。本文研究了基于Inspiring技术的产品设计模型,基于该模型研究了依据眼部血丝分布的人眼疲劳判断系统、指端多参数采集Inspiring系统,初步设计了基于Inspiring技术的产品所必需的人体信息采集分析模块的功能。在此基础之上重点研究了基于前臂表面肌电信号的Inspiring系统。该系统可以检测人体前臂表面肌电信号,根据人体肌肉疲劳模型判断肌肉的疲劳状态,然后对人体实施适当地激励,从而缓解人体的疲劳状态。针对体表肌电信号微弱、干扰大的特点,本文设计了一套高共模抑制比的微小信号检测电路;设计了基于LabVIEW的信号传输、存储与显示系统,并在MATLAB程序中实现了数字带通滤波器的设计和信号功率谱与中值频率的分析。通过体表肌电信息分析人体的疲劳状况是Inspiring系统设计的核心,本文通过深入研究体表肌电信号产生的机理与肌电信号的理论模型,选用了体表肌电信号功率谱分析和中值频率值作为判断肌肉疲劳的指标;通过对肌肉不同状态下频谱和中值频率的分析,找出了肌肉疲劳前后体表肌电信号的变化规律。判断出人体疲劳之后对人体实施激励是基于Inspiring技术的产品的重要功能。本系统采用了对人体进行背部按摩的激励方法,研究设计了多功能自动按摩垫的控制软件和硬件驱动电路,将其与前端表面肌电信号检测电路集成在电脑鼠标之中,基本实现了信号检测、疲劳分析与激励功能的集成。本论文深入分析了Inspiring技术的特点,并通过设计实例说明基于Inspiring技术的产品的研究方法,为今后基于Inspiring技术的产品设计奠定了良好的基础。更多还原

【Abstract】 Most existing products offer utilities by replacing specific human functions toachieve conveniences. Products become health hazards as functions are repeated andhuman becomes less capable as more functions are replaced. Inspiring technology isconcerned with establishing a new scientific foundation which integrates humansystem theories with modern technologies to develop a new generation of productsthat can simultaneously inspire human potentials while achieving their intendedfunctional purposes. Inspiring products seamlessly integrated with existing productsand intelligently tailor their inspiring functions for different users and adapt tochanging environments.We researched product model based on Inspiring technology and designed somesystems to validate the model, including the fatigue judgement system based on bloodsilk of eyes and the inspiring system based on the parameters acquisition of the finger.Those systems completed the human parameters acquisition function need byInspiring product. In order to complete the whole theory of Inspiring technology, wedesigned a new inspire system based on surface electromyography which can detectthe SEMG signal and estimate the status of muscle automatically. After analyzed thefatigue status of human it could motivate auto-massage function to lesson the fatigueof human.We used one high performance detecting circuit to acquire the SEMG signal anddesigned communication and display program to store and display the SEMG signal.In order to estimate the fatigue status of muscle, we researched some fatigue modelsbased on SEMG signal acquisition and selected the median frequency as the index offatigue status. It’s really a very good fatigue status index through a great deal ofexperiments. In the last design parts of this system we designed one infraredcontrolled massage chair to realize the inspire function. The inspire system based on SEMG signal analysis realized whole function ofInspiring technology. It’s the design foundation of product based on Inspiringtechnology.更多还原
