“…The FOMS was first designed to gather data on Paralympic alpine sit-skiing [30], where the TMM was mounted on the sitski, and the PMMs on poles called "outriggers." However, the system can be implemented on all ski poles and skis outside the laboratory.…”

A modular sensor application for measuring athlete performance in skiing sports was developed. Using inertial measurement units (IMUs) and load cells in a modular system, a force orientation measurement system, FOMS, was developed. A functioning prototype capable of measuring ski sports dynamics was created. Data processing using the system, a validation of the prototype in terms of angle measurement IMU accuracy, example data from in-field athlete testing, and visualization by animations are described. The system developed contains four subsystems: a controller, two pole measuring modules, and a terrain-measuring module. The system structure also allows for additional modules, making the system applicable to different sports. The IMUs use orientation-sensing components to measure pole orientations, which are used to calculate decomposed forces relative to the terrain. Data from different modules are synchronized using wireless communication and saved on SD cards with time stamps. A validation experiment was conducted in which the angles from the modules were compared with the Oqus motion capture system from Qualisys. Examples for athlete testing in both cross country and alpine skiing were calculated from the matrix provided by the different modules and are presented in graphs to evaluate the athlete. In addition, the relative pole/terrain coordinates are visualized in 2D and 3D animations for analyzing the movement pattern in connection with the applied forces, opening up a whole new level of sports analysis.

“…Modified outrigger skis, equipped to track orientation and force, revealed variations in athletes' techniques and identified efficiency losses. (Eikevåg et al, 2022;Silseth et al, 2021;Sletten et al, 2021). Similarly, adjustable outrigger skis, with varying angles of contact and length, were utilised to measure skier acceleration along a training track.…”

Human-centred approaches within the design cycle are crucial to enhance usability and inclusivity of products. However, the qualitative nature of traditional human factors evaluation can create bottle necks, prompting the need for more data driven methods. A framework for data-driven human factors is presented, looking to integrate mixed-method approaches. Case studies illustrate its usage in real-world scenarios and challenges are summarised, calling for robust data collection methods, balancing of mixed methods, a need for explainable systems, and interdisciplinary expertise.

“…The human aspect plays a crucial role in design research (Wilkinson and De Angeli, 2014). In sports adjusting equipment according to the human geometries have provided a substantial performance increase (Iriberri, Muriel and Larrazabal, 2008;Shan, 2008;Burt, 2014), and particularly in Paralympic sports (Mâsse, Lamontagne and O'Riain, 1992;Rapp et al, 2016;Eikevåg et al, 2020;Severin et al, 2021;Silseth et al, 2021). When comparing the geometry of an athlete's body and that of the equipment, a mismatch may arise, resulting in suboptimal equipment.…”

“…Therefore, the specific design question discussed in this paper is how to properly investigate what is the right fit in terms of work ergonomics when working with Paralympic athletes at the highest level. Early-stage prototypes can be created with infinite degrees of freedom in the relevant design space (Silseth et al, 2021) (i.e., the space describing the limits of the prototype) by first looking at the fundamentals in human geometries. So, using known design methodologies (Steinert and Leifer, 2012), we propose a new methodology for developing and evaluating user-adapted sports equipmentin our case for Paralympic sit-ski.…”

This article investigates human geometry in design, allowing exploration of unknown geometries in Paralympic sports equipment. By creating a configuration map exploring the solution-space, optimal sit-ski seating positions–in the sense of performance and ergonomics–can efficiently be found for individual athletes. A physical prototype was developed, and an experiment was designed to identify changes in performance due to different geometries. The design method and application make it possible to translate critical angles onto geometries, and test individuals for optimal work ergonomics.
