Abstract
Abstract. Single Display Groupware (SDG) supports face-to-face collaborators working over a single shared display, where all people have their own input device. Although SDG is simple in concept, there are surprisingly many problems in how interactions within SDG are managed. One problem is the potential for interference, where one person can raise an interface component (such as a menu or dialog box) in a way that hinders what another person is doing i.e., by obscuring another person’s working area that happens to be underneath the raised component. We propose transparent interface components as one possible solution to interference: while one person can raise and interact with the component, others can see through it and can continue to work underneath it. To test this concept, we first implemented a simple SDG game using both opaque and transparent SDG menus. Through a controlled experiment, we then analysed how interference affects peoples ’ performance across an opaque and transparent menu condition: a solo condition (where a person played alone) acts as our control. Our results show that the transparent menu did lessen the effect of interference, and that SDG players overwhelmingly preferred it to opaque menus.

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.
