Exploring the Structural Relationships of Microinteractions in Perception and Behavior by the Hedonic Motivation System Adoption Model

This study revisited the Hedonic Motivation System Adoption Model (HMSAM) through the literature on microinteractions, accomplished the model structure expansion and intrinsic composition of microinteraction regarding relationship and logic combining, and collected 140 valid data points through questionnaire surveys. The results showed that using microinteractions is largely adapted to the hedonic motivation system adoption model. Perceived ease of use is the basis for the use of microinteractions, which affects the perception of hedonic and perceptual experience. The hedonic state encompasses multiple emotional categories, with pleasure and control as important mediators affecting the behavioral intention to use, immersion, and perceived usefulness to varying degrees. The findings emphasize the impact of perceptual experience on using microinteractions, extending the theoretical structure and clarifying that "familiarity" of experience should be considered in interface design. These findings provide a basis for the theoretical construction of interface microinteractions and directions for future design practices.
