Wearable Technology for Signal Acquisition and Interactive Feedback in Autism Spectrum Disorder Intervention: A Review

Autism spectrum disorder (ASD) interventions increasingly harness the capabilities of wearable technology, utilizing predictive analytics of physiological signals and personalized sensory feedback. Herein, we review the key developments in the multifaceted application of wearable technology for ASD and highlight their potential value, covering both the state-of-the-art devices and requirements for ASD interventions. Wearable technology can be classified into two pivotal functional systems: signal acquisition and interactive feedback. The signal acquisition system employs an array of sensors for real-time physiological data monitoring in individuals with ASD, furnishing essential insights for the tailoring of customized therapeutic interventions. Additively, the interactive feedback system endeavors to ameliorate psychological and behavioral challenges, address sensory processing disorders, and enhance social and cognitive proficiencies. By facilitating diverse sensory stimulations and feedback mechanisms, wearable technology demonstrates a versatile approach to ASD intervention. Crucially, the principles and diverse applications of wearable technology in ASD are expounded upon, underscoring the emerging role of flexible electronics in this domain. Finally, the challenges and opportunities of wearable technologies are discussed, as well as the immense potential to revolutionize human-centered intervention solutions for ASD. The continued exploration of this dynamic field not only augments the quality of life and well-being of individuals with ASD but also presents an avenue for innovation at the intersection of technology and healthcare.
