Hybrid meetings are the new reality, yet they lack the richness of face-to-face interaction. In shared spaces, virtual or physical, interaction relies on more than words: proximity, non-verbal cues, and subtle movements all shape communication. Proximity captures how close we stand, where we face, and how we move around others. This paper investigates how proxemics in dyad and triad conversations translate across physical and virtual contexts. We conducted a study with 24 participants in four groups, completing social tasks under four conditions: face-to-face, co-located XR, remote XR, and hybrid XR. Our instrumentation of physical and virtual environments enables direct comparison. The work contributes a rich open dataset of 2.3 million rows across 32 columns, supporting comparative and replicable analysis. This is the first study to compare proxemics across face-to-face, co-located XR, remote XR, and hybrid XR, offering a foundation for understanding how social space translates across contexts.

Touchless displays often use mid-air gestures to control on-screen cursors for pointer interactions. Area cursors can simplify touchless cursor input by implicitly targeting nearby widgets without the cursor entering the target. However, for displays with dense target layouts, the cursor still has to arrive close to the widget, meaning the benefits of area cursors for time-to-target and effort are diminished. Through two experiments, we demonstrate for the first time that fine-tuning the mapping between hand and cursor movements (control-display gain – CDG) can address the deficiencies of area cursors and improve the performance of touchless interaction. Across several display sizes and target densities (representative of myriad public displays used in retail, transport, museums, etc), our findings show that the forgiving nature of an area cursor compensates for the imprecision of a high CDG, helping users interact more effectively with smaller and more controlled hand/arm movements.
