Surface computing allows for natural interactions with digital information through direct touch interaction, multi-touch detection, support for multiple simultaneous users, and object recognition. It utilizes technologies like Microsoft Surface, which uses infrared cameras under the display to sense touch input and objects placed on the screen without needing a touch-sensitive surface. Surface computing provides an intuitive interface and has applications in fields like education, retail, and business meetings.
Surface Computing
- 2. What is surface computing? A form of computing that offers “a natural way of interacting with information,” rather than the “traditional user interface” Surface computing typically includes four key attributes: Direct Interaction Multi–Touch Multi–User Object Recognition
- 3. DIRECT INTERACTION The ability to "grab" digital information with hands - interacting with touch/ gesture, not with a mouse or keyboard.
- 4. MULTI – TOUCH The ability to recognize multiple points of contact at the same time, not just one (Ex. One finger, like with most touch screens), but dozens.
- 5. MULTI – USER The Surface’s screen is horizontal , allowing many people to come together around It and experience a “collaborative, face–to– face computing experience”
- 6. OBJECT RECOGNITION Physical objects can be placed on the Surface’s screen to “trigger different types of digital responses” (Ex. cell phones, cameras, & glasses of wine)
- 7. Developments done till now. Types 1.Microsoft Surface 2. Laser Touch (Microsoft) 3. Gesture Tek 4. Perceptive Pixel 5. Diamond Touch (Mitsubishi) 6. Smart Table 7. Catchyoo 8. Reactrix 9. Sensacell
- 8. Microsoft Surface The Surface is not a touch-sensitive screen device… The screen itself is not electronic The Surface uses multiple infrared cameras beneath the screen/table top to sense objects, physical touch, etc The Surface “recognizes objects based on shape or by using domino-style identification (domino tags) on the bottom of the objects ” This information is processed and displayed using “ rear projection ”
- 9. Working of Microsoft Surface
- 10. Working of Microsoft Surface Screen: Diffuser -> ”multitouch" screen. Can process multiple inputs and recognize objects by their shapes or coded "domino" tags. Infrared: The ”machine vision" is aimed at the screen. Once an object touches the tabletop -> the light reflects back and is picked up by infrared cameras. CPU: Uses similar components as current desktop computers -> Core 2 Duo processor, 2GB of RAM and a 256MB graphics card. Wireless communication -> Wi-Fi and Bluetooth antennas (future -> RFID). Operating system -> modified version of Microsoft Vista. Projector: Uses a DLP light engine ( rear-projection HDTVs).
- 11. Where is it used? seminars Easy data transfer Airports Shopping malls,hotels,etc… Work place transportation
- 12. R&D Research work is going on several top universities like MIT (Massachusetts Institute of technology) with a innovation named SIXTH SENSE. This is an application of surface computing. Research on building user defined gestures that are used in surface computing that make the graphical representation more intuitive…
- 13. ADVANTAGES Data representation/transfer is more intuitive User friendly No use of input/output devices like mouse keyboard etc . . . Easily portable . . .
- 15. Conclusion Surface takes existing technology and presents it in a new way. It isn't simply a touch screen, but more of a touch-grab move-slide-resize and place objects on top of screen, and this opens up new possibilities that weren't there before
