Surface computing - Microsoft multi touch screen by gauravjindal


									Surface Computing/
Seamless Interface
                  Surface Computing
• 2001: Microsoft researchers Steve Bathiche and Andy Wilson
  developed idea of an interactive table
• 2003: 1st prototype was presented to Bill Gates for approval
• 2007: Interactive tabletop device was built that seamlessly
  brings both the physical and virtual worlds into one
• The table is built with wireless devices using Bluetooth and
  WI-FI technology (RIFD-Radio Frequency Identification will
  come later)
• Designed to match up with wireless objects placed on the table
• Multitouch screen is used like the technology behind the iPhone
  (no keyboard or mouse needed)

Note: There were 85 prototypes built before the final coffee table
look was established
                 Surface Computing

• Touch based graphical user interface
• Dynamic interface that can recognize multiple objects that are
  placed on the surface and distinguish the difference between
  them- two cell phones to compare features or prices
• Allows manipulation and direct control of digital content like
  photos- which can be resized bigger or smaller instantly with the
  touch of a finger(s)
• Uses multipoint sensors on the surface to recognize many
  points of contact so many people can use it at one time
             Surface Computing

• Surface technology attributes
  – Direct Interaction: interacting with touch instead
    of a keyboard or mouse
  – Multitouch: several points of contact at once
  – Multiuser: many users collaborating at one time
  – Object Recognition: physical objects have tags
    to recognize and trigger different responses

•   Microsoft operating system of Vista
•   Intel dual core processor backed by 2GB of RAM
•   256MB video card
•   5 video infared cameras
•   30 inch screen 1024 x 768 resolution (sits 21 inches off ground)
•   DLP projector

• Each unit will cost between $5,000 - $10,000 currently

1) Multitouch Screen
2) Infared LED light source- multipule cameras net resolution
   1280 x 960
3) CPU- Central Processing Unit
4) Projector- DLP light engine (like the ones in HDTV’s)
   resolution 1024 x 768 pixels

  • Demonstration of the
    multitouch screen with the
    use of an object- paintbrush
    to simulate painting a picture

  • Surface technology using an
    object with a tag- wineglass
    placed on surface to bring
    up other information about
    this particular wine
•   This new technology will be used first as an entertainment commodity in
    hotels, restaurants and retail venues
•   It will be initially launched at Harrah’s hotel in Las Vegas, Starwood
    Hotels and T-mobile.
•   Restaurant uses- see a virtual menu on screen and order right from the
    table your beverages and food selections then split the bill and pay
    electronically at the same time by putting your card on the surface.
•   Hotel uses- conceirge services for guests to look up a theater in the area
    and order tickets, pull up a map on how to get there and download the
    directions and the tickets into your cell phone or mobile device
•   T-mobile stores- can place two cell phones on the surface and compare
    the different price points and features, experiment with ring tones and
    look at plans then program the phone to your liking and have it all set to
    use before you walk out of the store
•   Video puzzle- use clear tiles on the surface and each tile has a moving
    piece of the puzzle that you have to match up with other pieces while the
    picture(video) is in perpetual motion on the tiles
                  Positive vs Negative

            Positive                                Negative
• Multi users- collaborative effort of   • Not portable- table has to stay put
    users interacting                    • Must own devices such as a cell
• Seamless- no wires or USB ports            phone to upload photos into or
• Instant download/upload of photos         share with others
• Users have more control of             • Have to be careful of table surface
    technology- ordering food or             to not damage it
    manipulating photos fast             • Very expensive to own
• Educational- learn more info           • Tailored to high end clients
