Linguistic and psycholinguistic tests will be more useful than motion capture technology in calibrating the borders between sign and gesture. The analogy between motion capture (mocap) technology and the spectrograph is flawed because only vocal articulators are hidden. Although information about gradience and variability will be obtained, the technology provides less information about linguistic constraints and categories. Better models are needed to account for differences between co-speech and co-sign gesture (e.g., different degrees of optionality, existence of beat gestures).

如何区分手势和手势：新技术不是答案

语言和心理语言测试在校准手势和手势之间的边界方面将比动作捕捉技术更有用。动作捕捉 (mocap) 技术和光谱仪之间的类比是有缺陷的，因为只有发声器是隐藏的。尽管将获得有关梯度和可变性的信息，但该技术提供的有关语言约束和类别的信息较少。需要更好的模型来解释共同语音和共同签名手势之间的差异（例如，不同程度的可选性、节拍手势的存在）。
