Research on immersive interaction design based on visual and tactile feature analysis of visually impaired children

To propose improved and innovative visual-tactile interaction design for visually impaired children, multi-modal combination approaches have been applied, such as voice interaction, touch interaction, and multi-modal systems, what's more, aided cognitive approaches help them deepen their understanding of objects, improve their cognitive level, and increase their interest. Methods: To improve the amount of information in the visual-haptic interface by integrating multiple sensory information, based on the cognitive patterns of visually impaired children, a questionnaire was used to design a tactile-visual UI for the main content objects of visually impaired children when using the Internet, from which difficulties and problems in the design of visual-haptic for visually impaired children were found, and design improvements were proposed based on the principles and methods of accessible design. RESULTS: The personalized and humanized design activities enhance the confidence and improve the quality of life of the visually impaired children group and produce positive effects, improving the cognitive clarity of visually impaired children while increasing their level of understanding, imagination, learning interest and aesthetic experience. Conclusion: The physical and mental characteristics and visual and tactile characteristics of visually impaired children are analyzed, and the application of UI interaction design is based on these characteristics. The essence of interaction design is outlined through experiments, and it is found that with the development of the Internet, big data and artificial intelligence, visually impaired children have many difficulties in the use of the Internet, and through the improved practice of immersive interaction design, the humanized design approach is used to enhance visually impaired children's experience of using network interfaces. Through the improved practice of immersive interaction design, we improve the way of visually impaired children using the Internet, narrow the gap between them and normal children in the interaction, and give humanistic care.
