Touch technology

  1. 1. Touch Technology<br />Interacting with Devices Through <br />Natural Human Gestures: <br />Touches, Swipes and Taps<br />
  2. 2. Today we are familiar with many multi-touch devices. <br />iPods<br />apple.com<br />Smartphones<br />apple.com<br />blog.oxagile.com<br />
  3. 3. Tablets<br />rgadget.com<br />Tablet <br />Personal Computers<br />apple.com<br />The iPad<br />rgadget.com<br />
  4. 4. These Devices Respond to Natural Human Touch<br />
  5. 5. These Devices Respond to Natural Human Touch<br />This works in a few different ways<br />
  6. 6. Method 1<br />Each device has an acrylic or glass surface<br />A finger touches the surface causing light to scatter<br />The reflection is picked up by sensors or cameras<br />The gesture is sent as data to software<br />The software interprets the data and initiates the appropriate response<br />
  7. 7. Method 2<br />A pressure-sensitive coating is applied to the screen surface<br />The coating flexes under varying pressure of the touch<br />Sensors interpret the pressure<br />The data is sent to software which relays the appropriate response<br />
  8. 8. Method 3<br />Handheld devices have panels that carry an electrical charge<br />The touch disrupts the electrical field<br />The disruption is registered and sent to the software<br />The software interprets the gesture and initiates the <br />appropriate response<br />
  9. 9. But this isn’t new technology<br />There were important breakthroughs beginning in 1953<br />
  10. 10. The first touch sensitive technology was invented in 1953<br />By Canadian <br />Physicist and Composer <br />Hugh Le Caine<br /><ul><li> He built the first music synthesizer
  11. 11. He invented the </li></ul>touch sensitive keyboard<br />collectionscanada.gc.ca<br />
  12. 12. In the 1960’s the power of computers was realized. <br />1960 <br />The DEC PDP-1<br /><ul><li> The PDP-1 sold for $120,000.
  13. 13. MIT wrote the first video game, Space War! for it.
  14. 14. A total of 50 were built.

  17. 17. In 1963, Ivan Sutherland invented SketchPad.<br />Objects were manipulated <br />directly on the computer screen<br />using a light-pen.<br />jabberwockydesign.com<br />jabberwockydesign.com<br />
  18. 18. SketchPadwas a significant breakthrough <br />“It Helped to define how we interact with <br />computers graphically today.1”<br /><ul><li>One of the first drawing programs
  19. 19. People drew directly on the computer surface
  20. 20. Natural human gestures (drawing) provided the input
  21. 21. Individual drawings were recognized as objects</li></ul>(This was an important step toward later programming)<br />1. http://www.newmediareader.com/cd_samples/Kay/index.html<br />
  22. 22. In 1969 Thomas Ellis Developed theGRAILprogram on the RANDtablet<br /><ul><li>Used light-pen
  23. 23. Translated freehand drawing </li></ul> into objects<br /><ul><li>Files could be saved
  24. 24. Previous text or drawings </li></ul> could be edited<br />public.csusm.edu<br />
  25. 25. In 1983 the HP-150 was introduced.<br /><ul><li> This was a Personal Computer
  26. 26. Used existing touch screen technology
  27. 27. Replaced certain keyboard functions with touch
  28. 28. Software was able to interpret touch data
  29. 29. Software then initiated program responses </li></ul>hp.com<br />
  30. 30. This same technology was used to create ATM’sin the 1980’s<br />plippard.com<br />
  31. 31. In 1992,computers became mobile <br />The Apple Newton: <br />The first PDA (Personal Digital Assistant)<br />This brought together many <br />previous technological innovations<br />Pen Computing Technology <br />Handwriting Recognition Software<br />Gesture Recognition <br />It also introduced Apple’s 1sttablet platform. <br />(Apple’s 2ndplatform is used in <br />the iPhone, iPod Touch, and iPad.) <br />gdgt.com<br />
  32. 32. These innovations and breakthroughs allow us to interact with our devices using Natural Human Gestures: Touches, Swipes and Taps<br />
