Synesthesia: A Neuropsychological Condition with Insights for Human-Computer Interaction

Core Concepts

Synesthesia, a neuropsychological condition where stimuli in one sensory modality trigger experiences in another, can provide valuable insights for enhancing human-computer interaction by understanding atypical perceptions and information processing.

Abstract

This review explores how synesthesia, a neuropsychological condition where stimuli in one sensory modality trigger experiences in another, can offer valuable insights for enhancing human-computer interaction (HCI).
The review is structured around three main perspectives:

Synesthesia as a condition associated with specific cognitive, perceptual, and behavioral anomalies. This view examines how synesthesia can be leveraged to better understand the dynamics of human-machine relationships and design more effective and personalized digital applications.

Synesthesia as a prevalent human experience, not limited to synesthetes but shared by all subjects. This perspective considers synesthesia as a significant model for HCI, potentially enabling new interaction paradigms between machines and humans in various contexts.

The exploration of synesthesia aims to decipher how atypical sensory and cognitive pathways can be encoded, enabling machines to actively participate in processing information originating from both the body and the environment. The overarching goal is to understand how synesthesia and anomalies in information processing can be harnessed within HCI, with a particular emphasis on contributing to digital technologies for medical research and enhancing patient care and comfort.

The review delves into the theoretical foundations of information theory and integrated information theory, highlighting their relevance in understanding perception, cognition, and consciousness. It also examines the concept of error in information transmission, both in the context of traditional information theory and the human perceptual system, and explores the remarkable adaptive capacity of the human brain.
The review aims to close the divide between theoretical knowledge and real-world application by exploring the intricate relationship between synesthesia and HCI, with the potential to enhance medical research, patient care, and comfort.
