GIM3D ::a pilot study of intuititve 3D motion control HMI

In many fields such as sports training, rehabilitation, and virtual prototyping, the ability to communicate movement information rapidly, intuitively, and unambiguously is essential. In sports, a key challenge for coaches is conveying precise motion adjustments to athletes. This short paper introduces GIM3D, a user interface designed to enable fast and intuitive manipulation of 3D running movements generated. A pilot study with five participants shows a strong willingness to use the tool (F-SUS score = 85.5). The UEQ S resulted an overall average of 2, with higher pragmatic quality (2.35) than hedonic (1.65). Users found the tool supportive, clear, and efficient. Initial results demonstrate the efficiency and plausibility of the generated movements, highlighting the potential of GIM3D as a tool for both practitioners and researchers in human motion science.
