Transcript

  • 1. Touch Technology
    Interacting with Devices Through
    Natural Human Gestures:
    Touches, Swipes and Taps
  • 2. Today we are familiar with many multi-touch devices.

  • 4. These Devices Respond to Natural Human Touch
  • 5. These Devices Respond to Natural Human Touch
    This works in a few different ways
  • 6. Method 1
    Each device has an acrylic or glass surface
    A finger touches the surface causing light to scatter
    The reflection is picked up by sensors or cameras
    The gesture is sent as data to software
    The software interprets the data and initiates the appropriate response
  • 7. Method 2
    A pressure-sensitive coating is applied to the screen surface
    The coating flexes under varying pressure of the touch
    Sensors interpret the pressure
    The data is sent to software which relays the appropriate response
  • 8. Method 3
    Handheld devices have panels that carry an electrical charge
    The touch disrupts the electrical field
    The disruption is registered and sent to the software
    The software interprets the gesture and initiates the
    appropriate response
  • 9. But this isn’t new technology
    There were important breakthroughs beginning in 1953
  • 10. The first touch sensitive technology was invented in 1953
    By Canadian
    Physicist and Composer
    Hugh Le Caine
    • He built the first music synthesizer
    • 11. He invented the
    touch sensitive keyboard

  • 12. In the 1960’s the power of computers was realized.
    1960
    The DEC PDP-1
    • The PDP-1 sold for $120,000.
    • 13. MIT wrote the first video game, Space War! for it.
    • 14. A total of 50 were built.
    • 15. Each had a cathode ray tube graphic display.

  • 16. Then the work began to improve Computer-Human Interaction

  • 17. In 1963, Ivan Sutherland invented SketchPad.
    Objects were manipulated
    directly on the computer screen
    using a light-pen.

  • 18. SketchPadwas a significant breakthrough
    “It Helped to define how we interact with
    computers graphically today.1”
    • One of the first drawing programs
    • 19. People drew directly on the computer surface
    • 20. Natural human gestures (drawing) provided the input
    • 21. Individual drawings were recognized as objects
    (This was an important step toward later programming)

  • 22. In 1969 Thomas Ellis Developed theGRAILprogram on the RANDtablet
    • Used light-pen
    • 23. Translated freehand drawing
    into objects
    • Files could be saved
    • 24. Previous text or drawings
    could be edited
    public.csusm.edu
  • 25. In 1983 the HP-150 was introduced.
    • This was a Personal Computer
    • 26. Used existing touch screen technology
    • 27. Replaced certain keyboard functions with touch
    • 28. Software was able to interpret touch data
    • 29. Software then initiated program responses

  • 30. This same technology was used to create ATM’sin the 1980’s

  • 31. In 1992,computers became mobile
    The Apple Newton:
    The first PDA (Personal Digital Assistant)
    This brought together many
    previous technological innovations
    Pen Computing Technology
    Handwriting Recognition Software
    Gesture Recognition
    It also introduced Apple’s 1sttablet platform.
    (Apple’s 2ndplatform is used in
    the iPhone, iPod Touch, and iPad.)
