用于虚拟现实多传感器应用的基本姿态和运动格式
A basic gesture and motion format for virtual reality multisensory applications
摘要：
考虑到异构系统和应用程序（音乐应用程序、3D运动控制、虚拟现实交互等）之间的运动数据交换日益重要，编码运动（例如由人类姿势产生的运动）的问题可能在未来几年成为中心问题。在过去的20年里，已经提出了各种格式来编码运动，特别是手势。尽管如此，这些格式在不同程度上是在相当特定的应用程序（角色动画，动作捕捉，音乐手势，生物力学问题......）的背景下设计的。本文介绍了一种新的文件格式，称为GMS（“手势和运动信号”），其目的是通过定义携带运动/手势信息的格式所需的最小特征，而不是通过收集现有格式通常给出的所有信息，从而变得更低级和通用。文章认为，鉴于其在虚拟现实环境中的存在越来越多，“手势信号”本身必须进行编码，并且需要特定的格式。所提出的格式具有这些信号的内部属性：维度，结构特征，变量类型以及空间和时间属性。文章首先回顾了手势控制干预的多感官虚拟对象的各种情况。然后推导出所提出的格式，作为一种手段来编码这种通用和可变的“手势和动画场景”。
英文摘要：
The question of encoding movements such as those produced by human gestures may become central in the coming years, given the growing importance of movement data exchanges between heterogeneous systems and applications (musical applications, 3D motion control, virtual reality interaction, etc.). For the past 20 years, various formats have been proposed for encoding movement, especially gestures. Though, these formats, at different degrees, were designed in the context of quite specific applications (character animation, motion capture, musical gesture, biomechanical concerns...). The article introduce a new file format, called GMS (for 'Gesture and Motion Signal'), with the aim of being more low-level and generic, by defining the minimal features a format carrying movement/gesture information needs, rather than by gathering all the information generally given by the existing formats. The article argues that, given its growing presence in virtual reality situations, the "gesture signal" itself must be encoded, and that a specific format is needed. The proposed format features the inner properties of such signals: dimensionality, structural features, types of variables, and spatial and temporal properties. The article first reviews the various situations with multisensory virtual objects in which gesture controls intervene. The proposed format is then deduced, as a mean to encode such versatile and variable "gestural and animated scene".
