This dataset contains data from 135 on-line and 16 off-line participants for the Pilot Test, 42 participants for EXP1, another 42 participants for EXP2, and 8 participants for EXP3. The Pilot Test established the VR environment conditions. Red and blue colors were selected based on arousal and valence ratings. EXP1 used a seated cognitive matching task under two conditions(Red/Blue). Emotion&Perception data were collected before and after the VR experience for Affective response and room appraisal. Objective measures include total matching score, number of fails, and time taken per level for Task Performance. Subjective measures include task workload, spatial perception, cybersickness, preference, and perceived room size/FoV. EXP2 used a physical block-stacking task under two conditions(Red/Blue). Emotion&Perception data were collected before and after the VR experience for Affective response and room appraisal. Objective measures include number of stacked blocks, dynamic movement, error distance, and error rotation for Task Performance. Subjective measures follow EXP1. EXP3 used a rhythm game task under a 2×2 design of color (red/blue) and task type (cognitive/physical). Objective measures include game score and number of good cuts. Subjective measures include task workload and cybersickness. The dataset includes questionnaire from the Sim-TLX, SP-IE, and Simulator Sickness Questionnaire (SSQ), collected during the VR experience.
