Today haptic feedback can be designed and associated to audiovisual content (haptic-audiovisuals or HAV). Although there are multiple means to create individual haptic effects, the issue of how to properly adapt such effects on force-feedback devices has not been addressed and is mostly a manual endeavor. We propose a new approach for the haptic rendering of HAV, based on a washout filter for force-feedback devices. A body model and an inverse kinematics algorithm simulate the user's kinesthetic perception. Then, the haptic rendering is adapted in order to handle transitions between haptic effects and to optimize the amplitude of effects regarding the device capabilities. Results of a user study show that this new haptic rendering can successfully improve the HAV experience.
如今，触觉反馈可以被设计并与视听内容（触觉 - 视听或HAV）相关联。尽管有多种方法可以创建个性化的触觉效果，但如何在力反馈设备上正确适配这些效果的问题尚未得到解决，并且大多是人工操作。我们提出了一种基于力反馈设备的洗出滤波器的HAV触觉渲染新方法。一个身体模型和逆运动学算法模拟用户的动觉感知。然后，对触觉渲染进行调整，以处理触觉效果之间的过渡，并根据设备能力优化效果的幅度。用户研究结果表明，这种新的触觉渲染可以成功改善HAV体验。
