Abstract: A computer-implemented system and method generate comparative non-therapeutic engagement outputs for evaluation of candidate stimuli. Time-series physiological signals are acquired from one or more wearable sensing devices during user interaction with physical, digital, or multisensory stimuli. The signals are preprocessed using modality-specific operations and used to generate a synchronized multimodal feature representation derived from at least two physiological signal modalities. A trained computational inference model performs non-linear multimodal fusion to generate a continuous multi-dimensional engagement vector representing a quantified physiological interaction response of the individual user. One or more similarity or distance measures are computed between the engagement vector and reference engagement vectors associated with the same individual user.
