    • There is provided a system and method for database driven action capture. By utilizing low cost, lightweight MEMS devices such as accelerometers, a user friendly, wearable, and cost effective system for motion capture is provided, which relies on a motion database of previously recorded motions to reconstruct the actions of a user. By relying on the motion database, calculation errors such as integration drift are avoided and the need for complex and expensive positional compensation hardware is avoided. The accelerometers may be implemented in an E-textile embodiment using inexpensive off-the-shelf components. In some embodiments, compression techniques may be used to accelerate linear best match searching against the motion database. Adjacent selected motions may also be blended together for improved reconstruction results and visual rendering quality. Various perceivable effects may be triggered in response to the reconstructed motion, such as animating a 3D avatar, playing sounds, or operating a motor.
    • 提供了一种用于数据库驱动的动作捕获的系统和方法。 通过利用低成本,提供轻量级MEMS装置,例如加速度计,用户友好的,可穿戴的和具有成本效益的用于运动捕获的系统,其依赖于先前记录的运动的运动数据库来重建用户的动作。 通过依靠运动数据库,避免了积分漂移等计算错误,避免了对复杂而昂贵的位置补偿硬件的需求。 加速度计可以使用廉价的现成组件在E纺织实施例中实现。 在一些实施例中,可以使用压缩技术来加速针对运动数据库的线性最佳匹配搜索。 相邻的选定运动也可以混合在一起以改善重建结果和视觉渲染质量。 可以响应于重建的运动而触发各种可感知的效果,诸如动画化3D化身,播放声音或操作电动机。
