With the number of people with visual impairments (e.g., low vision and blind) continuing to increase, vision loss has become one of the most challenging disabilities. Today, haptic technology, using an alternative sense to vision, is deemed an important component for effectively accessing information systems. The most appropriately designed assistive technology is critical for those with visual impairments to adopt assistive technology and to access information, which will facilitate their tasks in personal and professional life. However, most of the existing design approaches are inapplicable and inappropriate to such design contexts as users with visual impairments interacting with non-graphical user interfaces (i.e., haptic technology). To resolve such design challenges, the present study modified a participatory design approach (i.e., PICTIVE, Plastic Interface for Collaborative Technology Initiatives Video Exploration) to be applicable to haptic technologies, by considering the brain plasticity theory. The sense of touch is integrated into the design activity of PICTIVE. Participants with visual impairments were able to effectively engage in designing non-visual interfaces (e.g., haptic interfaces) through non-visual communication methods (e.g., touch modality).
