Uncoupled Stability Dynamic Range for Hunt-Crossley Modeled Virtual Environments
Bibliographic record
Abstract
Viscoelastic medium is a common environment that is simulated as a virtual environment in haptic simulation systems. Kelvin-Voigt (KV) and Hunt-Crossley (HC) are models commonly used to simulate viscoelastic environments in haptic simulation systems. Due to the sample-and-hold process, the range of dynamics - viscosity and elasticity, that can be rendered in a stable way is limited. While uncoupled stability, as a stringent stability condition, has been analyzed for KV virtual environments, it has not been evaluated for HC environments. In this letter, we experimentally evaluate the range of dynamic parameters for each model that result in uncoupled stability. To compare the results, we map the HC parameters to the KV parameter space. To confirm the mapping, we conduct a user study to compare the viscosity and elasticity effects perceived by the users.

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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
