iGroup Presence Questionnaire

A standardized questionnaire for measuring the sense of presence experienced in virtual environments, developed by the iGroup consortium. The IPQ assesses three sub-scales: spatial presence (feeling physically present in the virtual world), involvement (attention focused on the virtual environment), and experienced realism (how lifelike the environment feels), plus a general presence item. In accessibility research, the IPQ is used to evaluate whether BLV users achieve meaningful immersion in virtual environments through non-visual interaction methods.
