Application of Multimodal Information Fusion in Intelligent Pedometers for Visually Impaired Children
摘要
In 1974, the United Nations first introduced the concept of “design for accessibility”, which greatly expanded the audience for design, and such design concepts also emphasized a focus on visually impaired children. However, for visually impaired children, traditional mobility aids tend to ignore their unique needs, often focusing on a single visual sense and ignoring the reliance of visually impaired children on other senses such as auditory, tactile and vestibular senses. This leads to a developmental lag in coordination, balance and spatial perception. Therefore, in this paper, we have innovatively designed a smart wearable walker for visually impaired children based on sEMG technology, which combines a foot vibration walking assistance system with decentralized corrective sensors, and intelligently analyses the functional movement assessment of muscle strength during walking. Through continuous perceptual reminders and corrections, the spatial perception ability and muscle force memory of visually impaired children are examined, while the walking cycle and joint angles are recorded by combining with parents’ APP terminals, and a fall prevention system for young children is proposed to provide balance perception and support protection for the torso. This study plays an important role in muscle development and posture correction of visually impaired children of different ages, it combines the single function of traditional children’s walkers with the needs of special populations, promotes their comprehensive psychophysiological development, and the powerful wearability and practicality meets the needs in the context of the times.
