Exploring the Need and Design for Situated Video Analytics
Bibliographic record
Abstract
Visual video analytics research, stemming from data captured by surveillance cameras, have mainly focused on traditional computing paradigms, despite emerging platforms including mobile devices. We investigate the potential for situated video analytics, which involves the inspection of video data in the actual environment where the video was captured [14]. Our ultimate goal is to explore the means to visually explore video data effectively, in situated contexts. We first investigate the performance of visual analytic tasks in situated vs. non-situated settings. We find that participants largely benefit from environmental cues for many analytic tasks. We then pose the question of how best to represent situated video data. To answer this, in a design session we explore end-users’ views on how to capture such data. Through the process of sketching, participants leveraged being situated, and explored how being in-situ influenced the participants’ integration of their designs. Based on these two elements, our paper proposes the need to develop novel spatial analytic user interfaces to support situated video analysis.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
