    Designing for the Visually Impaired Designing for the Visually Impaired Presentation Transcript

    • DESIGNING FOR THE VISUALLY IMPAIRED
      ENABLED BY DESIGN
    • Introduction >>
      WHO?
      WHAT?
      WHAT NOT?
    • Learnabilityfirst time accomplishmentEfficiencyperform quickly
      Memorability
      Reestablishing proficiency
      Our approach >>Biomimicry
    • “The role of technology is to mirror our humanness. We were born with everything we need:good technology reminds us of that.”
      Jack Dorsey (@jack), CEO Twitter
      Conceptual design >>
    • PLAN
      ASSISTIVE DEVICE
      INFORMATION FLOW >>
    • Audio-to-text
      Plug-ins for google maps >>
      Tablet Connectivity
    • Audio registered as text on-cue
      Given point appears on map
    • List of Suggested routes can be toggled for change on map
    • Screen grayed out (inactive)
      Highlighted select route (active)
    • DIGITAL IMPRESSION BOARD - HAPTIC PEN
      The next few slides have used images of Wacom’sIntuos 4 for illustration purposes only**
    • Digital impression board >>
      Magnet clay/ Magnetized liquid
      Customizable Button initiators
    • Digital impression board >>
      Button initiators mapped for similar on-screen functionality
      Button also serve as cue initiators to commands
      Electromagnetic waves change texture to imprint the chosen route
    • << HAPTIC PEN
      In-built microphone to receive voice commands
      Finger-tip grip pad for haptic senses
      Automated nib changer for texture-feel
      Thumb-button to initiate text-to-speech
    • << HAPTIC PEN
      A comic illustration of the tracing of a route using the Haptic pen on texture
    • What it doesn’t do
      • GPS tracking
      • Security
      • Retract ability
      • Automation
      • Texture detection
      What it does
      • Ultrasonic obstacle detection
      • Vibratory buttons
      Adding on to the ultra-cane >>
    • Pointing you to the right direction
      Underside of Haptic torch integrated with GPS /compass
      Retractability option for non-obtrusiveness
      Grip transfer force probe to feel texture
      Handle covered to give *grip* feedback (handholding)
    • Pointing you to the right direction- navigating without maps
      Force exerted at points for
      ‘pulling’, ‘pushing’ sensation
      Shoulder and Waist studied to be the turning points in assistive/guided walking
      Assistive jacket >>
      Automating the Ultra cane
    • Scenario >> Planning
    • Scenario >> Assistive device
    • “ If we want users to like our software, we would design it to behave like a likeable person.”
      Alan Cooper
      Self assessment >>
      • System status is visible to user
      • Minimizes the length of process by using natural intuitive memory (long term)
      • Reduces the time required to do activity by transferring it to natural actions done in life
      • Supports flexibility in attaining a task
      • Is mostly automated so system status is not required to be visible to user
      • Texture probe triggers long-term memory and brings in action
      • Reduces motor processing time
      • 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 system
      Backup for when system incurs errors. What happens?
      Added flexibility to allow user freedom with his actions.
      Segregating perception of texture. Muddling to the brain?
    • ENABLED BY DESIGN
      NO QUESTIONS? GOOD.
