The question of gesture and motion takes more and more importance with the development of gesture controllers , haptic systems, motion capture systems, etc. Motion and gesture file formats are widely used today in many applications that deal with motion and gesture signal. It is the case in domains like motion capture, character animation , gesture analysis, biomechanics , musical gesture interfaces, virtual surgery. Those formats are low-level formats, i. The BVH format is mainly used as a standard representation of movements in the animation of humanoid structures.

The question of gesture and motion takes more and more importance with the development of gesture controllers , haptic systems, motion capture systems, etc. Motion and gesture file formats are widely used today in many applications that deal with motion and gesture signal. It is the case in domains like motion capture, character animation , gesture analysis, biomechanics , musical gesture interfaces, virtual surgery. Those formats are low-level formats, i.
The BVH format is mainly used as a standard representation of movements in the animation of humanoid structures.
It is currently one of the most popular motion data formats and has been widely adopted by the animation community probably because of its simple specifications.
The name defined by the user is associated to the predefined label for the biped segment. A name defined by the user is associated to the predefined label expected by Character Studio. In addition, the format includes several other variables to be exported such as joint angles, segment velocity and free acceleration, center of mass trajectory and calibrated sensor data of the individual motion trackers.
The format is a variant of the BVH file format developed by Biovision. The ASK file Alias Skeleton only contain information concerning the skeleton and, as a result, does not contain any information about the channels or the movement.
The offset coordinates are absolute, unlike the BVH in which they are relative. The SDL file associated to the ASK file contains the data of the movement but it can contain much other information concerning the scene than the very samples of the movement.
Adaptative Optics is a company dedicated to the creation of hardware support for the motion capture. This format was developed by Acclaim , a video game company.
The Acclaim format is composed of two different files, one for the skeleton and the other one for the movement. The separation between these two types has been done because the same skeleton is often used for numerous distinct movements. It allowed stocking the data coming from a magnetic motion capture system. The GRC file format is file format to store motion capture data from Synertial mocap system.
GRC includes RAW data from inertial sensors such as rotation, acceleration, and magnetic field strength , skeleton details, absolute position of the skeleton root and various metadata notes, TimeCode ,..
Thanks to the fact that the RAW data from this file are read by Synertial SDK and the skeleton structure is recomputed each time they are needed, the file format is memory efficient. It has been created as an alternative to the BVH format to make up for its main drawbacks. The Tak, pronounced "take," file format is used by the Motive software developed by OptiTrack. The file can contain information on:. It contains not only the raw data from the full body motion capture system they developed but also the output data coming from their face tracker.
The CSM format is an optical tracking format that is used by Character Studio an animation and skinning plug-in for 3ds Max for importing marker data. The V file format is a binary motion data format developed by Vicon Motion Systems. The VSK file contains the skeleton Hierarchy. The V file can contain the following data: - Marker data - Global segment translation and rotation data - Local rotation data with root translation data.
It stores 3D coordinate information, analog data and associated information used in 3D motion data capture and subsequent analysis operations. At the time of its development all 3D motion capture systems stored their data in multiple files, each with a different proprietary format, making the exchange of data between various biomechanics and gait analysis laboratories very difficult.
With the introduction and adoption of the C3D file format by all major 3D motion capture companies all necessary 3D information, analog data and parameters describing the data can be seamlessly transferred between researchers and laboratories, regardless of the hardware or environment used to collect the data.
The major features of the C3D file format are listed below:. Prior to the introduction of the C3D file format almost all biomechanics and gait analysis software was written for each specific 3D system manufacturers file format.
As a result, researchers and clinicians were restricted to either writing their own analysis software or else using only the software provided by with their 3D data collection system.
The introduction of the C3D format resulted in the availability of a substantial body of third-party software and freed the research community from dependence on any individual 3D data system manufacturer.
The GMS Gesture and Motion Signal format is a low-level, binary, minimal, but generic, format for storing Gesture and Motion Signals in a flexible, organized, optimized way. A closed binary file format developed by House of Moves for use in their proprietary software called at the time Diva.
This file format is essentially a dump of a Diva scene. It includes all translational marker data as well as all rotational bone data in the scene and more. The FBX proprietary file format.
