有效的赛艇需要人类的体能和技术能力。因此，技术能力的教与学主要限于水上训练。这个项目的目的是开发一个赛艇模拟器。该模拟器应作为赛艇新手和专业人士使用的高水平室内训练工具。用户应该实时感知关于他们当前的表现和他们的环境的声音、视觉和触觉提示。新开发的赛艇模拟器由一个赛艇船体组成，船体上安装了多个位置传感器，连接在桨和座位上。船体安装在洞穴内的讲台上。洞穴包括投影屏幕、扬声器系统和分别用于视觉、声音和触觉反馈的驱动绞车。建立了一个实时的数学划船模型，该模型计算了船速和桨动力作为划桨和使用者运动的函数。所有相关的船、桨和用户参数都可以任意设置，从而允许模拟不同的船类型。通过将模拟结果与水上测量数据进行比较，验证了赛艇模型的有效性。由该模型预测的船速和桨行力与实验数据具有较高的相关性。此外，赛艇模拟器还成功地与专业赛艇运动员进行了测试，他们对模拟器的真实感水平和室内训练的适用性给予了高度评价。根据划艇运动员的反馈，对模拟器进行了各种硬件和软件扩展，包括增加划艇和桨的驱动自由度，以改善触觉反馈。
Efficient rowing requires both physical and technical abilities of the human. Teaching and learning of the technical abilities is thereby mainly restricted to on‐water training. The aim of this project was to develop a rowing simulator. This simulator should serve as a high‐level indoor training tool that can be used by rowing novices and professionals. The users should perceive acoustic, visual, and haptic cues about their current performance and their environment in real time. The newly‐developed rowing simulator consists of a rowing boat hull equipped with multiple position sensors attached to the oar and seat. The boat hull was mounted on a podium placed inside a Cave setup. The Cave comprises projection screens, a loudspeaker system, and actuated winches for visual, acoustic, and haptic feedback, respectively. A mathematical real‐time rowing model was developed, which computes the boat velocity and the oar force as a function of the movement of the oar and the user. All relevant boat, oar, and user parameters can be arbitrarily set, thus allowing the simulation of different boat types. The rowing model was validated by comparing results of the simulation with data from on‐water measurements. Both the boat velocity and the oar force predicted by the model correlated highly with the experimentally‐obtained data. Furthermore, the rowing simulator was successfully tested with professional rowers who rated the level of realism and the applicability of the simulator for indoor training as high. Based on the feedback of the rowers, various hardware and software extensions are planned for the simulator, including an increase of the number of actuated degrees of freedom of the boat and the oar, in order to improve the haptic feedback.
