Measurements
Questionnaire - Physical Presence Measures
To measure the helper's immersion in the virtual environment, we combined the Slater-Usoh-Steed Questionnaire (SUS) and Presence Questionnaire (PQ) to assess their perception and control over the MR environment.
Questionnaire - Social Presence Measures
We used the Inclusion of Other in the Self (IOS) Scale to measure the perceived psychological closeness to the other player and the Social Presence Module of the Game Experience Questionnaire (GEQ) to gauge how much attention players paid to their counterpart during task completion.
Interview
Semi-structured interviews were conducted to gain in-depth insights into the participants' experiences, focusing on their perceptions of the environment, collaboration with their partners, and task complexity under different scenarios.
Recording
To assess participants' behaviors, we recorded audio and video, segmenting them into behaviors like communication frequency, task-related content proportion (audio data), and unique actions in various scenarios (video data).
