Multimodal Direct Manipulation in Video Conferencing: Challenges and Opportunities
Bibliographic record
Abstract
Tools supporting immersive live video conferencing (VC) have gained popularity recently across diverse application domains. A core component of the experience is augmenting video communication with multimodal interactive media. While many direct-manipulation techniques for VC communication have been proposed in existing literature, the usability and preferences for these techniques have never been formally studied. In this paper, we examine how embodied interaction democratizes content authoring, and propose a rehearsal-to-performance (RtP) framework along with a VC system, Clio, that enables performers to directly interact with their media using voice, gesture, and external devices such as tablets. We evaluate existing operation-to-modality mappings for VC communication, as well as describe novel mappings not present in the literature. A series of studies demonstrate modality preferences and potentials for incorporating real-time direct-manipulation tools to create expressive augmented VC performances.

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.
