Configurable 3D Rowing Model Renders Realistic Forces on a Simulator for Indoor Training

In rowing, rowers need outdoor and indoor training to develop a proficient technique. Although numerous indoor rowing machines have been proposed, none of the devices can realistically render the haptic, visual, and auditory characteristics of an actual rowing scenario. In our laboratory, we developed a simulator to support rowing training indoors. However, rendered forces with the initial rowing model, which was based on a simplified fluid dynamic model that approximated the drag/lift forces, were not perceived realistic enough for indoor training by expert rowers. Therefore, we implemented a new model for the blade–water interaction forces, which incorporates the three-dimensional rotation of the oar and continuously adjusts drag/lift coefficients. Ten expert rowers were asked to evaluate both models for various rowing aspects. In addition, the effect of individualization of model parameters on the perceived realism of rowing forces was elaborated. Based on the answers of the experts, we concluded that the new model rendered realistically resistive forces and ensured a smooth transition of forces within a rowing cycle. Additionally, we found that individualization of parameters significantly improved the perceived realism of the simulator. Equipped with a configurable rowing model, our simulator provides a realistic indoor training platform for rowers.

“…In the recent years, vibrotactile stimuli have been applied for directional guidance to improve motor learning and to reduce mental workload [2,30]. Applications of vibrotactile displays can be found in sports: soccer, skating and cycling [34], dancing [8], boat rowing [27], snowboarding [31] and karate [5]. A vibrotactile feedback system has been adopted also in the field of music to teach violin bowing [33].…”

Two joystick-based teleoperation is a common method for controlling a remote machine or a robot. Their use could be counterintuitive and could require a heavy mental workload. The goal of this paper is to investigate whether vibrotactile prompts could be used to trigger dual-joystick responses quickly and intuitively, so to possibly employ them for training. In particular, we investigate the effects of: (1) stimuli delivered either on the palm or on the back of the hand, (2) with attractive and repulsive mappings, (3) with single and sequential stimuli. We find that 38 participants responded quicker and more accurately when stimuli were delivered on the back of the hand, preferred to move towards the vibration. Sequential stimuli led to intermediate responses in terms of speed and accuracy.

This paper presents design work and empirical work, exploring a novel way of steering player behaviour and performance in sports, called 'coaxing'. We propose that athletic performance might be influenced by tricking players into thinking that their athletic abilities are different from what they really are. We approach this proposition from three different angles. First, we use related work to theoretically ground the concept of coaxing in literature. Second, we take a research-throughdesign approach to illustrate the potential of coaxing for sports practice, specifically volleyball. Third, we carried out an experimental study to shed light on the effectiveness of coaxing, also in the context of volleyball. For the experimental study, we explored the idea of coaxing by means of an augmented ball-catching task. For every participant, we quantified their ability to intercept fly balls and presented them with visualisations that either overstated or understated this ability; in the expectation that this would impact how they acted in the ball-catching task. While the effects of coaxing failed to reach significance, data suggest that coaxing might yet be a viable form of steering player behaviour. Contrary to our hypothesis, participants whose abilities had been understated mostly outperformed their counterparts. We discuss the particularities of the current findings and their implications for sports practice. We conclude with practical and theoretical recommendations to further develop the concept of coaxing.
