Abstract
Mobile and wearable devices based activity recognition systems utilize built-in sensors to identify the activities performed by users pervasively. However, most of these systems do not explicitly present the sensing process to users and are prone to uncertainty. The presence of uncertainty makes users feel confused about the behaviors of activity recognition systems, which may affect the confidence of users. Uncertainty visualization has become an interesting research topic purporting to help users better understand systems. In this paper, we present an uncertainty visualization to reveal the process of mobile and wearable devices based activity recognition systems. We conducted an experiment to evaluate the uncertainty visualization by using a particular simulated mobile and wearable devices based activity recognition application. The results showed that the uncertainty visualization was effective in helping users understand and trust the judgments and inferences of the activity recognition application. Based on the advice of participants, we concluded a few directions to improve the uncertainty visualization.

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
