Abstract
Walking assistive devices are designed to improve the mobility of the user. Although promising, active devices have a problem: they become uncomfortable after prolonged usage. Large motor torques provided by active devices effectively assist the movements of the user. However, these torques transfer forces to the user's limbs creating significant discomfort and limiting the duration of usefulness. This work used force mapping in an attempt to identify zones of pressure concentration that may cause discomfort as well as examined the effect that various pads had on these zones. The device tested in this research was the K-SRD <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">TM</sup> by B-Temia Inc. Force analysis identified certain zones of high force concentration. Possible causes were identified and potential solutions were suggested. Furthermore, the padding testing showed that the force transfer was similar regardless of the thickness of the pads. However, the stiffer padding materials distributed the forces over a greater area and decreased the pressure at the interface. This seems to indicate that the thickness of padding is less important than the distribution of applied forces. In all, interfaces that distribute forces over large surface areas may be beneficial. Further research efforts are needed in order to develop a physical human-machine interface that will ensure the success of exoskeletons in the future.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
