Multi-Dimensional Nature of Human-Centered Design: an Autoethnographic Analysis of the Seiko Bell-Matic Wristwatch Using Information-Theoretic Methodologies

Abstract: Human-Centered Design (HCD) emphasizes empathy to understand users' needs, yet the complexity of these needs makes HCD an evolving and open-ended objective. This paper uses Seiko’s Bell-Matic wristwatch as an autoethnographic case study to explore discrepancies between the intended design and dynamic user needs. Applying the Networked Two-way Communication Channels (NTCC) model reveals new insights into the interaction dynamics of the Bell-Matic's unique mechanical alarm feature. This study proposes a novel approach to modeling UI interactions as multi-dimensional communication processes, enabling comparisons between system functionality and user needs. Ultimately, the paper reinterprets HCD by evaluating the alignment of functional entropies between systems and users.
