  1. 1. Seminar onSURFACE COMPUTING Presented By, Shonima Prakash IInd sem MCA B1 1
  2. 2. INTRODUCTION:-Surface computing is the term for the use of aspecialized computer GUI in which traditional GUIelements are replaced by intuitive, everydayobjects.Over the past couple of years, a new class ofinteractive device has began to emerge, what canbest be described as ―surface computing‖.Instead of an I/O devices ,the user can interactdirectly with a touch sensitive screen. 2
  3. 3.  Two Examples are there:- Surface Table Top Surface Computing Perceptive Pixel Surface Table Top is a 30inch display in a table form factor . Surface can simultaneously recognize dozens and dozens of movement. 3
  4. 4. Perceptive Pixel is company launched byProfessor Jeff HanPerceptive Pixel builds six –figure plus custommulti touch drafting tables and enormousinteractive wall displays for large co-operationsand military situation rooms. 4

  6. 6. What is Surface Computing???Surface Computing is a new way of workingwith computers beyond traditional I/O devices.It is a revolutionary multi touch computer withdifferent look and feel.It is a natural interface that allows the user tointeract with digital contents such as photos ,music, paintbrush…with their hands ,withgestures and by putting real-world objects onthe surface. 6
  7. 7. The most common and popular type of surfacecomputing is that of touch screen monitors ofthe type that can be found on many modernphones.More recently though both Microsoft and Applehave come up with new ways to use surfacecomputing.Microsoft’s plan is a device called MicrosoftSurface which takes the form of a large tableand would be used in places such as hotels andcasinos . 7
  8. 8. The key difference between this and other similardevices is the multi touch system.This allows users to use both hands tomanipulate things such as photos, as well as theuse of hand gestures and even physical gestures.Other features on the Microsoft surface allows forwireless communicates between devices so thingslike phones, cameras and laptops can sync withthe table and move data between them effortlessly. 8
  9. 9. Surface ComputerThe name Surface comes from "SurfaceComputing‖ and Microsoft envisions the coffee-table machine as the first of many such devices. 9
  10. 10. The term "surface" describes how its used.Surface computing opens up a whole newcategory of products for users to interact with. It blurs the lines between the physical andvirtual worlds.Surface Computing is a powerfulmovement, because it is a change from DOS toGUI.This uses a multi touch screen as userinterface. 10
  11. 11. 200 200 200 200 200orgins 1 3 4 5 7An Idea Inspired by Cross-division Collaboration:-In 2001,Stevie Bathiiche and Andy Wilson ofMicrosoft Research began working together todevelop an interactive table .Their vision was tomix the physical and virtual world to provide a richinteractive experience. 11
  12. 12. 200 200 200 200 200orgins 1 3 4 5 7 T1 prototypeHumble Beginnings on a Table In early 2003, the team presented the idea toBill Gates, Microsoft Chairman ,and within themonth the first prototype was born , based on theIKEA table with a table cut through its top and asheet of architect vellum as a diffuser. 12
  13. 13. 200 200 200 200 200orgins 1 3 4 5 7 Humble Beginnings on a Table:-In 2004, the team grew and become the SurfaceComputing group. Surface prototypes ,functionalityand applications were continuosly refined . Theteam built more than 85 early prototypes for use bysoftware developers, hardware developers anduser researchers. 13
  14. 14. 200 200 200 200 200 orgins 1 3 4 5 7Hardware DesignBy late 2004, the Microsoft Surface developmentPlatform was established and attention turned its form. A number ofDifferential experimental prototypes werebuilt, including 14

With a sleek, translucent surface, people engage with Surface using natural handgestures , touch and physical objects placed on the15
  16. 16. Four key Attributes Direct Intertaction Multi-touchcontact Multi-user experience Object recognition 16
  17. 17. Direct Interaction•Direct interaction means that , we can interact with theSuface by using our fingers.•Users can actually grab digital information with theirhands and interact with content through touch and gest•No other input device is needed to give input. 17
  18. 18. Mutli-touch Contact•Ordinary touch screen provides single touch Sensing.• Multi-touch refers to a touch sensing surfacesability to recognize more than one touch at same time.•Surface Computing recognizes many point of contactSimultaneously, Dozens and dozens of items at same ti 18
  19. 19. Multi-user experience•A single touch screen can support more thanone user.•The horizontal form factor makes it easy forseveral people to gather around surface computerstogether,providing a collaborative, face‐to‐face computing 19
  20. 20. Object recognition•Users can place physical object on the surface totrigger different types of digital responses , includingthe transfer of digital content.•Object recognition is done in the surface by usingspecial bar codes called Domino tags.•These are infrared sensitive patterns which areread by the infrared sensing cameras inside the 20
  21. 21. Working Microsoft Surface uses cameras to sense objects, hand gestures and touch. This user input is then processed and displayed using rear projection. By rear projection system which displays an image onto the underside of a thin diffuser. Objects such as fingers are visible through the diffuser by series of infrared sensitive cameras, 21
  22. 22. Cntd… positioned underneath the display. An image processing system processes the camera images to detect fingers, custom tags and other objects such as paint brushes when touching the display. The objects recognized with this system are reported to applications running in the computer. 22
  23. 23. Technology Behind Surface Computing Total Internal Reflection Technology 23
  24. 24.  Perceptive Pixel’s touch screens work via frustrated total internal reflection Technology. The acrylic surface has infrared LEDs on the edges. When one or more fingers touch the surface, the light diffuses at the contact points, changing the internal-reflection pathways. A camera below the surface captures the diffusion and sends the information to image- processing software, which translates it into a command. 24
  25. 25. Features  Multi-touch display.  Horizontal orientation.  Dimensions.  Materials. 25
  26. 26. Multi-touch display:-• Multitouch technology has been around since early research at the University of Toronto in 1982.• Multitouch devices accept input from multiple fingers.• Multiple users simultaneously allowing for complex gestures, including grabbing, stretching, swivelling and sliding virtual objects across the table. 26
  27. 27. • With multitouch devices, one or more users activate advanced functions by touching a screen in more than one place at the same time.For example, a person could expand or shrinkimages by pinching the edges of the displaywindow with the thumb and forefinger of onehand.Horizontal orientation:-• The 30 inch display in a table-sized form factor . so several people can gather around 27
  28. 28. Diamensions:-• It is 22 inches high,21 inches deep, 42 incheswide.Materials:-• The table top is acrylic, and its interior frame ispower coated steel. 28
  29. 29. StructureHardware of Surface Computer consists of 4 partsas- 1. Screen 2. Infrared light 3. CPU 4. Projector 29
  30. 30. How does a screen Work ? Screen• A diffuser turns the Surfaces acrylic tabletop into a large horizontal ―multi-touch‖ screen, capable of processing multiple inputs from multiple users.• The Surface can also recognize objects by their shapes or by reading 30 coded tags.
  31. 31. How does an Infrared work? Infrared• Surfaces "machine vision" operates in the near-infrared spectrum, using an 850- nanometer-wavelength LED light source aimed at the screen.• When objects touch the tabletop, the light reflects back and is picked up by infrared cameras. 31
  32. 32. How does CPU work?• Surface uses many of the same components found in everyday desktop computers.• Wireless communication with devices on the surface is handled using Wi-Fi and Bluetooth antennas. CPU 32
  33. 33. How does a Projector Work?• Microsofts Surface uses the DLP(Digital Light Processing) light engine found in many rear projection DTV’s .• The cameras can read nearly infinite number of simultaneous touches and are limited only by processing power. Projecto r 33
  34. 34. Who’s using Surface Today?•Currently only commercially available and being used in the retail, hospitality, automotive, banking and healthcare industries.• Current customers are AT&T, T-Mobile, the Rio All Suite Hotel & Casino in Las Vegas, Sheraton Hotels, Disney Innovations House in California, Hotel 1000 inSeattle, Harrah’s Entertainment, and Starwood Hotels and Resorts Worldwide. 34
  35. 35. Advantages: Large surface area to view different windows and applications. Data Manipulation - Selecting, moving, rotating and resizing. Quick and easy to use. More Than One User –several people can interact Objects Recognition - Increased functionality aiding user in speed and ease of use. 35
  36. 36. Disadvantages: Incredibly expensive and not Portable. Currently designed only in some areas. Loss of Privacy - Open for many to view. Tailored to high end clients 36
  37. 37. Applications:-1) Digital photo handling with finger tips:- We can handle images directly with our fingers.. 37
  38. 38.  Photos are arranged into albums that look like files. Tapping the file once spreads it around the screen and from there user can drag, rotate, and resize the images. Since Surface can detect many touches at the same time, multiple people can sort and resize pictures. Manipulating the images is better than the real photos. 38
  39. 39. 2)Instantly compares while shopping:- We can directly compare different products just by placing them on the surfa This is done using object recognition technology. Eg:-two cell phones placed on the surface 39
  40. 40. 3)Interaction with digital images Digital images are manipulated, shared & send via technologies like Wi- Fi, Bluetooth, etc. Drag and drop images. 40
  41. 41. 4) Surface Restaurant:- Orders can be placed on the Surface from a sliding menu , by choosing a category and 41
  42. 42. scrolling left and right through the availableoptions.Items can be dragged into a Central ―ordering area‖ and a single tap on the order button sends the list out to the waiter. 42
  43. 43. 5)Paint:- In Paint Applications ,there are three draw modes that can be toggled by touching an icon on the bottom of the toolbar:-Brush,Paint and Reveal. 43
  44. 44.  Reveal is a kind of negative brush that showsa background bitmap underneath. Brush mode is a bit spotty and tends to skip. Paint mode is smooth and fun 44
  45. 45. 6)Water:- Water is used as an ―attract mode‖ for Surface desktop. 45
  46. 46.  The default background picture is an image ofsmooth pebbles that appear to sit a thin layerof rippling water. Tapping any ware on the display causes largerripples to spread out from the point of contact. 46
  47. 47. 7)Music:- This application works like a media player. 47
  48. 48.  That is, music files are stored and arranged by albums, then select the files and drag into the ―Now playing‖ section. Addition, Playing music that is already stored unit’s hardware. Huge playlist can be easily manipulated. 48
  49. 49. Surface Computing-In Future Slim device. The new hardware will be 4 inches thin Computer scientists hope to incorporate this 49
  50. 50. of technology in peoples’ daily lives…. Futuregoals are to surround people with intelligentsurfaces-look up recipes on kitchen counteror table, control TV with coffee table, etc As form factors continue to evolve, surface computing will be in any number of environments— schools, businesses, homes and in any number of form factors New quick controls. 50
  51. 51. Conclusion:-o Surface takes existing technology and presentit in a new way.o Its not simply a touch screen, but more of atouch-grab-move-slide-resize-place objectson top of the screen.o Fundamentally changes the way we interactwith technology. 51
