Abstract:

In this white paper, the opportunities and current obstacles to use the Move 4D markerless motion tracking system (Instituto de Biomecanica de Valencia - IBV), for capturing human product interactions is discussed. In particular, this whitepaper focuses on scanning cyclists to map and improve biomechanical efficiency and aerodynamics. If successful, it could lay the technological foundation to extend current CFD (computational fluid dynamics) analyses, with flow simulations executed with a dynamically moving body and bicycle based on a high resolution and high framerate 4D mesh. Furthermore, the homologous mesh export function could allow bike fitters to use digitally standardized measurement points for biomechanical assessments. In contrast, marker-based motion tracking systems require hand placement of markers that are susceptible to faults such as placement position errors, low battery while recording, and falling off the skin. A markerless system could also improve flexibility for researchers to find new relevant measurement points due to the flexibility of digital markers. Current obstacles are revealed during an exploratory observation: 1) recording a professional time trail rider. A primary obstacle in capturing human product interactions is that the system does not provide a usable homologous mesh, due to the system's inability to separate the object, in this case, the bicycle, from the cyclist. Two follow-up observations explore the effect of coating objects, used in human-product interactions, with material that do not emit infrared (IR) in broadbands of 3–5 μm and 8–14 μm: 2) exploring coatings that avoid detection by IR cameras, and 3) recording a human product interaction with an object coated in a material that avoids detection by IR cameras. Results shows that these coatings on objects used in a human product interaction enables the system to capture the actor’s full dynamic movement, without the object being captured. This way a dynamically moving, watertight, and accurate homologous 4D mesh can be created of the actor.
