Abstract
A Personal Identification Number (PIN) is a widely adopted authentication method used by smartphones, ATMs, etc. PINs offer strong security and can be reset when compromised (unlike biometric authentication). However, PINs can be inaccessible for blind or low vision (BLV) users due to screen readers voicing PINs to bystanders or potential shoulder surfing attack risks---bystanders could watch the PIN being entered without the user noticing. To address this, we present OneButtonPIN, an interface to improve PIN entry accessibility and security for BLV users. Here, a single on-screen button, when pressed and held, triggers a haptic vibration sequence. A digit is entered by counting the vibrations and releasing the button. We explored introducing random timings to the vibration sequence to increase security. A week-long evaluation with 9 BLV participants and a security study with 10 sighted participants acting as shoulder surfers demonstrated OneButtonPIN's usability and resilience against eavesdropping.

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
