As core architectural environments for cultural heritage preservation and public education, museums are evolving from static exhibition spaces into immersive, multisensory interactive environments. The sensory attributes of the architectural environment—including multimodal information such as light, sound, and touch—exhibit a dynamic coupling with visitors’ emotional states. Responding to visitors’ growing emphasis on emotional enhancement, this study aims to improve the emotional experience of museum tours through multisensory compensation strategies. First, we conducted an experiment at the Shaanxi Archaeology Museum, capturing facial videos of participants during their tours and utilizing a facial expression analysis system for continuous emotion recognition. Subsequently, drawing on theories of multisensory interaction and emotion regulation, we constructed a multisensory emotion regulation model to guide the sensory compensation experiment. Visualization analysis of the results confirmed that multisensory compensation strategies within the architectural environment significantly increased positive emotions (from 48.23% to 60.78%). This study focuses on the mechanisms by which sensory compensation strategies in the architectural environment influence visitors’ emotional experiences, aiming to promote the transformation of cultural heritage spaces from “function-oriented” to “emotion-oriented” environments.
