Abstract: With the development of intelligent wearable equipment, an increasing number of interaction modalities can be selected. Simple interaction modal superposition not only fails to meet interaction needs, but also causes interaction cost issues such as user information overload and increased cognitive load. Therefore, the importance of multi-modal interaction evaluation and optimal design of smart wearable devices has become increasingly prominent. Taking the intelligent helmet as an example, a multi-modal interactive evaluation method (EUC method) based on efficiency, user experience, and cost is proposed. And optimize the design for the modal selection of military and police intelligent helmets based on EUC method. Among them, the interactive evaluation test is based on task performance measures (i.e., task completion time, error rate and number of operations) and user perception measures (i.e., perceived usability and workload), as well as using ANOVA and other methods to study the correlation and influence between interaction indicators and variables to complete the effectiveness of multiple modal combinations under boundary conditions and multiple postures. Finally, the optimal design suggestions and solutions for the multi-modal flexible configuration are proposed for the military and police intelligent helmets based on evaluation results.
