Abstract

Reaction time, the ability to detect, process and respond to stimuli, is one of the fundamental factors in human computer interaction, and is a key cognitive skill in clinical and healthy populations. Good reaction time allows us to respond to stimuli and situations with agility and efficiency. How to train and improve a person's reaction time has become an important research question. In this paper, we present a new training genre which combines the user-centered personalized training objects generation with precise tracking of foot interaction.Virtual objects are created with respect to the user's features and historical training effectiveness, and are in motion. A foot tracking algorithm based on three-Gaussian model is designed to support interaction with stepping on moving virtual objects. We present the design and implementation of the system, as well as user studies. Findings illustrate that the reaction time performances are significantly improved following of seven days of training based on foot interaction.

支持反应时间训练系统的脚部互动

反应时间是检测、处理和响应刺激的能力，是人机交互的基本因素之一，也是临床和健康人群的一项关键认知技能。良好的反应时间使我们能够敏捷、高效地对刺激和情况做出反应。如何训练和提高人的反应时间已成为一个重要的研究问题。在本文中，我们提出了一种新的训练流派，它将以用户为中心的个性化训练对象生成与脚部交互的精确跟踪相结合。我们设计了一种基于三高斯模型的脚部跟踪算法，以支持踩踏移动虚拟对象的交互。我们介绍了系统的设计和实施以及用户研究。研究结果表明，经过七天基于脚部交互的训练后，反应时间表现有了明显改善。

期刊介绍： With the advent of very powerful PCs and high-end graphics cards, there has been an incredible development in Virtual Worlds, real-time computer animation and simulation, games. But at the same time, new and cheaper Virtual Reality devices have appeared allowing an interaction with these real-time Virtual Worlds and even with real worlds through Augmented Reality. Three-dimensional characters, especially Virtual Humans are now of an exceptional quality, which allows to use them in the movie industry. But this is only a beginning, as with the development of Artificial Intelligence and Agent technology, these characters will become more and more autonomous and even intelligent. They will inhabit the Virtual Worlds in a Virtual Life together with animals and plants.
