Design of Time-Continuous Rating Interfaces for Collecting Empathic Responses in VR, and Initial Evaluation with VR180 Video Viewing

We design and assess interfaces for time-continuous self-reporting of empathic responses in VR using dimensions of empathic concern and personal distress. Visual styles included Circular Rating Indicators (CRI), Color Dials (CD), and Interactive Curving Faces (Frowny). Input types included desktop knobs and VR controller touchpads. We considered the intuitiveness, effectiveness, and in-trusiveness of designs with viewers of a stereo 180° video. Initial results highlight the CRI and Frowny as promising choices, calling for future examination of their effectiveness.
