Tactile Ideation

A design methodology adapted for people with visual disabilities that replaces visual ideation techniques (such as sketching, post-it notes, and ideation cards) with tactile and auditory alternatives. Techniques include using physical objects as conversation prompts (show-and-tell), clay or craft materials for non-visual prototyping, talking buttons with pre-recorded audio as alternatives to written cards, and object brainstorming where random tactile objects inspire new ideas. Tactile ideation enables people who are blind or have low vision to participate meaningfully in creative design processes that would otherwise exclude them, supporting inclusive co-design of new technologies. Research has shown that physical objects serve multiple functions: keeping hands busy to reduce social pressure, providing a tactile way to share and reference ideas, and encouraging lateral thinking.
