The Future of Surface

• A lab that Microsoft has in Cambridge has just
  reported that they have created a system that not
  only allows touch interaction like Multitouch
  technology, but it also happens to allow you to
  twist, bend, pull and squeeze different parts of
  the interface in order to make certain things
  happen.  As one person put it, this is almost
  like Multitouch on steroids.
• Adaption to wall-mounted and podium-style
  surfaces

• ATT April ...twenty-two different Surface
  Computers in four of their stores in the country.
  When people place products on the Surface,
  information regarding the product will come on
  the screen. The customer can then directly
  interact with the Surface in order to change the
  information that is being shown or to bring up
  additional information regarding the product on
  the screen. The customer can even put two
  products on screen at the same time in order to
  do an on the spot comparison between the two
  products before choosing which one they want to
  purchase.

Future Display Units

• Holographic TV
• Mid-air Video Displays
• 3D Display Monitor
• Head-mount Displays

9
Holographic TV

• Haloscreen
• Is a holographic film which displays any image
  feed through a projector at a specific angle onto
  a transparent display
• How it works
• Light fed at a specific angle is displayed all
  other light is ignored

10
Pros and Cons of Holographic TVs

• Pros
• bright and sharp image quality - even in brightly
  lit environments
• Any type of projector can be used to cast the
  image
• Accepts all inputs for playback on screen

• Cons
• projector sits on the floor about 5 feet behind
  the screen
• Expensive

11
Mid-air Video Displays

• Project video or images into mid-air
• Supports
• JPEG
• MOV
• FLASH
• QUICKTIME
• Text
• MORE
• Added Capabilities w/installed Software
• Cursor control
• Navigate and interact with simple content
• Heliodisplay Video

12
Current Negatives Aspects of mid-air Video
Displays

• Needs controlled lighting for best working
  conditions
• Images become less visible under bright lighting
• Wind and bright lights interfere with image
  visibility
• image definition and fidelity are inferior to
  those seen on CRTs and LCDs
• Expensive

13
3D Display Monitors

• Idea is to view 3D technology without using
  glasses
• Accomplished by
• Taking advantage of binocular disparity
• Stereoscopic imaging
• Odd Pixel ColumnsLeft Eye
• Even Pixel ColumnsRight Eye
• Combine the 2 get 3D image from your brain
  focusing in on display

14
Current Negatives of 3D Display Monitors

• Not much leeway in where you need to sit, but you
  dont have to stay perfectly erect.
• Still a bit blurry
• Can make you feel nauseated
• 3D Projection can be viewed by only one person
• Real-world applications supporting this
  technology is small

15
Head-mounted Displays

• Display device, worn on the head that has a small
  display optics
• Uses
• Video Gaming
• Portable Entertainment
• Private Movie Watching
• Remote Internet / Images
• Electronic Magnification Devices
• Connect them to
• Cell phones
• IPods
• VCR and DVD Players
• Gaming Systems
• Computers

16
Current Negatives of Head-mounted Displays

• Sagging Issues
• Becomes Heavy after periods of time
• Can cause health problems such as
• Eye straining
• Eye problems
• Headaches
• Seizures
• Nausea
• Vomiting

17
Input Devices

• LASER KEYBOARDS

18
Laser Keyboards

• Mac, PC, Blackberry, PDA, SmartPhone
• Zipo / Small Cell Phone
• Using two separate infrared beams
• Industry Advantages
• Surface Compatibility
