Subclaims¶

q1 i? On a 60 Hz panel the highest representable temporal frequency is 30 Hz, which sits below the critical flicker-fusion frequency and inside the photosensitivity band, so the mechanism must fall back on static spatial decoys alone with correspondingly weaker capture asymmetry. → Gupta 2026

Gupta, L. R., Kaur, K., Ram, D. S., & Parani, P. (2026). Behaviorally Adaptive Visual Diversion for Inclusive and Resilient Digital Assessment Delivery. arXiv preprint, under review at IEEE Transactions on Learning Technologies. https://arxiv.org/abs/2608.03531 doi:10.48550/arxiv.2608.03531

q1 · i? · theoretical · r3

Design-constraint analysis in Section 5.1 combining WCAG 2.1 flash thresholds, photosensitivity data, and the flicker-fusion requirement; the temporal argument holds at 120 Hz and above.

"On a 60 Hz panel the highest representable temporal frequency is 30 Hz, which sits below f_cff and inside the photosensitivity band. The temporal channel of Equation (4a) is therefore unavailable on commodity 60 Hz hardware"

Related Claims¶

• Theoretical results establish content fidelity, rendering stability, entropy boundedness, and integrity convergence for the BAVD model
• Accessibility attenuation buys reduced sensory burden at a measurable, monotone cost in capture resistance
• The additive entropy decomposition is an upper bound, not a security measure; adversary uncertainty is a conditional entropy
