近年来，手势识别被广泛应用于界面。流行的手势主要是手臂动作和全身动作。虽然手的形状是一个很好的标志，可以用微小的动作表达丰富的信息，但实际应用很少。这是因为现有的方法存在几个问题：手指感觉的阻塞和手指运动的干扰，手的位置和姿势的限制，以及复杂的初始配置。在这项研究中，我们试图通过观察手腕轮廓来识别手的形状，手腕轮廓随着手指的运动而变化。我们已经开发了一种健壮的腕表式设备，可以捕捉手腕轮廓，并从大量受试者那里收集了数据。利用收集到的数据，我们进行了几种条件下的手部形状识别实验。为了克服定位偏差和个体差异，设计了两种特征类型。通过实验，确定了特征的潜力，提取了一些有效的特征。此外，在识别目标属性的设计上，我们通过实验考察了目标手型的数量和手型的组合，揭示了目标设计的一些线索。
Recently, gesture recognition is widely used as interface. Popular gestures are mainly arm motion and whole body motion. Although hand shape is a good sign that can express rich information with small motions, few applications are in practical use. That is because the existing methods have several problems: blocks of finger sense and interference with finger motion, restrictions of hand position and posture, and complex initial configurations. In this study, we try to recognize hand shapes by observing the wrist contour, which varies with finger motions. We have developed a robust wrist-watch-type device that captures wrist contour, and have collected data from a substantial number of subjects. With the collected data, we conduct hand shape recognition experiments in several conditions. To overcome the positioning deviations and individual differences, two feature types are designed. Through the experiment, potential of the features is confirmed, and some effective features are picked up. In addition, concerning the design of recognition target properties, we examine the number of target hand shapes and the combination of hand shapes through the experiment, and several clues for target design are revealed.
