Abstract
A force illusion device is a portable mechanism that generates the illusion of an external force applied on the device. It has potential applicability as a navigation aid for blind or visually impaired people. Force illusion devices that use a cyclic translating mass to generate the illusion have one drawback. Their users will feel a moment caused by gravity acting on this moving mass. It is desired to compensate for this moment since it is likely to disturb the force illusion. This paper proposes an additional mechanism capable of partial moment compensation. A hypocycloid straight-line mechanism is selected from a variety of candidate mechanisms. A prototype of both the force illusion device and additional compensation mechanism is built to enable experimental validation. The dynamic measurements show that the mechanism behaves as is expected from the calculations. The hypocycloid mechanism adds little complexity with only 4 additional axis, yet reduces the gravitational moment with 80%.

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
