【摘要】：随着移动计算与人机交互技术的快速发展,可穿戴设备成为了继智能手机、平板电脑之后,科技界的另一个热点。微型化、便携化等特性使得可穿戴设备成为真正的UGC(用户生成内容),可以无时无刻地收集用户创造的内容。与此同时,此类设备的信息输出方式却极为有限,缺乏良好的用户体验。直接高效的触觉反馈可以免受外界环境的干扰,是移动交互环境中传递信息的理想反馈方式。振动反馈是如今可穿戴设备中最为常见的反馈之一,但现有的大多数腕带设备振动模式单一,所能传递的信息只有"振动"与"未振动"两种。为了研究腕带设备对于复杂信息的传递,我们设计了一款腕带原型系统。通过将四个振动马达嵌入在腕带的不同位置,可产生多种振动模式,如单个马达振动形成的"点振动"模式及多个马达按顺序依次振动所形成的"环形振动"模式等等。基于此腕带原型的主要工作成果如下:第一,通过先导实验验证其他振动参数(如振动强度)对振动模式识别的影响,得出无明显区别的振动强度仅影响模式识别时间,对识别正确率无显著影响。第二,通过实验对多种振动模式(九种)的感知度进行差异性评估,得出易被用户区分的振动类型顺序为:"点振动"类型、"全振动"类型、"对角振动"类型、"环形振动"类型。第三,通过之前的工作,保留并改进了五种振动模式,评估五种模式在静止状态下和运动状态下的感知差异,得出静止状态下对振动的感知程度要明显优于运动状态。本研究是腕带设备中振动反馈交互的基础研究,对此类设备传递复杂信息的设计具有一定指导意义。
[Abstract]:With the rapid development of mobile computing and human-computer interaction technology, wearable devices have become another hot spot in science and technology after smartphones and tablets. Miniaturization and portability make wearable devices a true UGC (user-generated content) that collects user-generated content all the time. At the same time, the information output of such devices is very limited, lack of good user experience. Direct and efficient tactile feedback is an ideal way to transmit information in mobile interactive environment. Vibration feedback is one of the most common feedback in wearable devices nowadays, but the vibration mode of most wrist band devices is single and the information can only be transmitted by "vibration" and "non-vibration". In order to study the transmission of complex information in wristband equipment, we designed a prototype system of wristband. By embedding the four vibration motors in different positions of the wristband, a variety of vibration modes can be produced, such as the "point vibration" mode formed by the vibration of a single motor and the "ring vibration" mode formed by the sequential vibration of several motors. The main results based on the prototype are as follows: first, the effects of other vibration parameters (such as vibration intensity) on vibration pattern recognition are verified by pilot experiments, and the results show that no obvious difference in vibration intensity only affects the pattern recognition time. It has no significant effect on the recognition accuracy. Secondly, by evaluating the perception of many kinds of vibration modes (nine) through experiments, it is concluded that the order of vibration types that are easy to be distinguished by users is: "point vibration" type, "full vibration" type, "diagonal vibration" type, "ring vibration" type. Thirdly, through the previous work, five vibration modes are retained and improved, and the difference of perception between the five modes in the static state and the moving state is evaluated. It is concluded that the perception of vibration in the static state is obviously superior to that in the moving state. This research is the basic research of vibration feedback interaction in wrist band equipment, and has certain guiding significance for the design of transmitting complex information of this kind of equipment.
