Ergonomic Analysis of Age-Friendly Product Design: Focusing on Smart Device Brand “Osmile” in Taiwan

초록

This study examines age-friendly design in elderly-care wearables using Taiwan’s smart care brand “Osmile.” Four ergonomic dimensions—physical/motion, sensory/perception, cognitive/interaction, and emotional/trust—were correlated to perceived usefulness (PU), perceived ease of use (PEOU), and perceived service quality (PQS). Within an extended Technology Acceptance Model (TAM)/Unified Theory of Acceptance and Use of Technology (UTAUT) framework, PU, PEOU, and PQS explain the attitude toward use and behavioral intention. Survey data from 268 older adults and caregivers were analyzed using structural equation modeling. The results suggest that better ergonomic quality strengthens PU and PEOU and determines the perceived service quality. Additionally, the model clarifies the manner by which these beliefs translate into more positive attitudes and stronger intention to continue using elderly-care wearables, thus offering guidance for improving interface accessibility and support services for aging users.
