Designing for the Visually Impaired

This document discusses designing assistive technologies for the visually impaired. It proposes a digital impression board and haptic pen that work together to allow users to feel textures and routes on a map. The digital board would use magnets to change textures under the pen tip, while the pen contains buttons, a microphone and vibration to provide feedback. It also suggests expanding these ideas to develop an assistive jacket with integrated GPS and texture detection to guide navigation without maps. The goal is to mirror human abilities and transfer tasks to natural actions through biomimicry and intuitive, memorable interfaces.

- 27. System status is visible to user
- 28. Minimizes the length of process by using natural intuitive memory (long term)
- 29. Reduces the time required to do activity by transferring it to natural actions done in life
- 30. Supports flexibility in attaining a task
- 31. Is mostly automated so system status is not required to be visible to user
- 32. Texture probe triggers long-term memory and brings in action
- 33. Reduces motor processing time
- 34. No flexibility allowed since system is programmed to work in one way alone with no interference.Future Extensions >>Addition of ‘help’ feature without hindering the processing speed of systemBackup for when system incurs errors. What happens? Added flexibility to allow user freedom with his actions.Segregating perception of texture. Muddling to the brain?
- 35. ENABLED BY DESIGN NO QUESTIONS? GOOD.
