Abstract
A sensory room is a space where people with symptoms of sensory hypersensitivity can temporarily rest and escape from stimuli such as sound and light. This study aims to increase the relaxation effect in sensory rooms by developing an interactive device that operates in synchronization with the user's breathing. A non-contact breath estimation using an RGB-Depth camera sensor, the system transforms physical structures in accordance with the user's breath. The device applies biofeedback technology that utilizes biometric information to the sensory room environment to achieve real-time optimization based on the physiological state of the individual user. The device was evaluated by physiological indices of heart rate variability, salivary amylase, and respiration information, as well as subjective evaluation. Preliminary results from eight participants indicated a trend toward reduced heart rate and salivary amylase, although we need to test more participants to further validate the results.
