“…Although the industry has long used color filters or contact lenses to help visually impaired people add brightness to restore some vision in certain situations, they are not adapted to all shades of color. In recent years, researchers have found that accurate spectral separation and acquisition of different frequency band image information can be achieved using multispectral imaging, and the imaging results can reflect the vision of normal people and color-blind people [9] , which can help visually impaired to increase the brightness and color in order to restore part of their vision. Incorporating multispectral lenses into the product design allows visually impaired people to access spectral information for better object recognition.…”

Based on the theory of sensory compensation, this paper mainly applies the multimodal interaction design method to solve the difficulties and challenges faced by the visually impaired people watching the game as an application scenario, so as to provide a reference for the accessibility design. In terms of research ideas, the technical principles and applications of visual enhancement, auditory compensation, tactile compensation and olfactory compensation are investigated by combing the development of sensory compensation and the three realization methods of visual enhancement, visual substitution and visual replacement for visually impaired people. By dividing the game-viewing scene into five sub-scenes to gain insight into the specific needs of visually impaired people, combining the needs with the three forms of application of sensory compensation mentioned above, discussing their adaptive relationship with different scenes, and exploring the multimodal interaction design mode under the different needs of visually impaired people, in summary, this research come up with the design of the multimodal interaction system for the visually impaired people used to watch the game. The design example verifies that the multimodal interaction design mode based on sensory compensation design with intersecting and complementary senses of vision, audio, and tactility can help to improve the quality of spectator services and daily travel and life of the visually impaired people.

“…MLAs are also widely used in the field of biomedicine. Di et al [8] used photolithography and thermal reflow to fabricate a multi-spectral 9 × 9 lens array that aimed at assisting individuals with color blindness. Each lens was coated with a filter of a different color to simultaneously capture light in a range of wavebands.…”

In a previous study, we presented a novel manufacturing process for the creation of 6 × 6 and 8 × 8 microlens arrays (MLAs) comprising lenses with diameters of 1000 μm, 500 μm, and 200 μm within an area that covers 10 mm × 10 mm. In the current study, we revised the manufacturing process to allow for the fabrication of MLAs of far higher density (15 × 15 and 29 × 29 within the same area). In this paper, we detail the revised manufacturing scheme, including the micromachining of molds, the partial-curing polydimethylsiloxane (PDMS) bonding used to fuse the glass substrate and PDMS, and the multi-step casting process. The primary challenges that are involved in creating MLAs of this density were ensuring uniform membrane thickness and preventing leakage between the PDMS and glass substrate. The experiment results demonstrated that the revised fabrication process is capable of producing high density arrays: Design I produced 15 × 15 MLAs with lens diameter of 0.5 mm and fill factor of 47.94%, while Design II produced 29 × 29 MLAs with lens diameter of 0.25 mm and fill factor of 40.87%. The partial-curing PDMS bonding system also proved to be effective in fusing PDMS with glass (maximum bonding strength of approximately six bars). Finally, the redesigned mold was used to create PDMS membranes of high thickness uniformity (coefficient of variance <0.07) and microlenses of high lens height uniformity (coefficient of variance <0.15).
