Research on the Design Principles of Intelligent Interactive Products from the Dual Perspectives of Human Factors Engineering and User Experience

Abstract

In response to the problems of insufficient physiological adaptation and complex cognitive operations in current intelligent interactive products, covering common categories such as smart bracelets, car navigation, and smart home terminals, this article takes a dual perspective of ergonomics (physiological adaptation) and user experience (psychological perception) - the former focuses on the physiological laws of the human body, while the latter pays attention to the psychological needs of users. The two complement each other to solve the shortcomings of a single perspective design. Combining national standards, specific industry cases, and third-party research data, five design principles are extracted: human body size adaptation, operational force efficiency optimization, cognitive process simplification, instant feedback design, and emotional adaptation. Research has shown that dual perspective fusion can simultaneously improve product physiological comfort and user satisfaction, providing practical references for product design such as smart wearables and smart homes. All conclusions are based on publicly available standards and examples.
