We present Minus×Minus=Plus, an interactive system that externalizes collective neural activity to create a shared affective space. The system allows two participants to visualize their stress in real
time via Electroencephalography (EEG) and to jointly transform it through two forms of haptic interaction.
Sharing with others can play a vital role in helping to cope with stress and emotional burdens. Biofeedback systems have been growing in HCI as supportive of individual stress management; however, the potential of leveraging neurofeedback systems for embodied forms of interpersonal stress sharing remains unexplored.
The system was tested with 110 participants (55 pairs), and their experience of embodied stress sharing was evaluated. Results show that our system significantly promoted the sharing process, underscoring the central role of visual and haptic modalities. This work contributes empirical evidence and design insights for developing neurofeedback systems that foster interpersonal stress sharing and support mental health.
