Interpretative Structural Modeling Analyzes the Hierarchical Relationship between Mid-Air Gestures and Interaction Satisfaction

Mid-air gestures as a new form of human-computer interaction has a wide range of satisfaction factors, for which the primary and secondary relationships and hierarchical relationships between factors are unclear. By examining usability definitions, collecting satisfaction questionnaires and user interviews, 30 observed variables were obtained and a scale was developed. A total of 310 valid questionnaires were collected, and six latent variables were summarized through factor analysis. The matrix quantitative analysis of latent variables based on interpretative structural model theory was used to construct a hierarchical model of influencing factors of satisfaction with mid-air gestures. The study shows that the influencing factors of mid-air gesture satisfaction can be divided into three levels. The first layer of attractiveness is the direct influencing factor on the surface and the goal of mid-air gesture design. In the second layer, Simplicity and Efficiency, Simplicity and Tiredness, and Tiredness and Friendliness interact with each other. Simplicity positively affects Friendliness, and Efficiency positively affects Tiredness. The third layer, Intuitiveness is the root layer influencing factor, which affects Simplicity. This study provides a theoretical basis for the design of mid-air gesture so that it can be designed and selected more objectively.
