Technology Acceptance and Hand Anthropometry (TAHA) Model: Insights from Somatosensory Technology

Somatosensory technology is an emerging technology used in applications such as home entertainment, medical and healthcare. It can track human hand movement and enable users to interact with digital devices or physical environment by using hand gesture(s). Effectiveness of somatosensory technology is determined by the compatibility between the technology's operational features and the anthropometric characteristics of the user's hand. Currently, only limited guidance is provided for designers and manufacturers in their development of consumer somatosensory technology products. Motivated by the shortfalls in the extant hand anthropometry literature, this study examines how hand anthropometry influences user technology acceptance. Drawing from Technology Acceptance Model (TAM), we develop Technology Acceptance and Hand Anthropometry (TAHA) model to investigate the impact of hand-size on user's somatosensory technology acceptance. A product trial experiment of 60 participants was conducted to test TAHA model. The results show that hand-size influences the relationship between perceived ease of use and behavioral intention to use somatosensory technology. Our findings have significant implications for hand anthropometry research and practice.
