  • 1. Ivan SutherlandAtul NarkhedeApril 2013A pioneer in Human Computer Interaction
  • 2. Turing AwardIvan Sutherland1988“For his pioneering and visionary contributions tocomputer graphics, starting with Sketchpad, andcontinuing after”2
  • 3. Key ContributionsAmazing range of fundamental contributions toComputer graphics and other disciplines.Graphical User InterfaceCADVirtual RealityComputer GraphicsAsynchronous circuits3
  • 4. SketchPadSketchpad: A Man-machine GraphicalCommunications SystemDoctoral Dissertation at MIT1963First GUI ever!!4
  • 5. SketchPad: HardwareTX-2 computerDeveloped at MIT Lincoln Labs in 1958Computer designed to facilitate HumanComputer Interaction (unlike the batchcomputers prevalent then)o 7” CRT with 512 X 512 pixelso Light pen (to identify locations on the screen)o Button boxo Transistor-based (instead of vacuum tubes)5
  • 6. SketchPad: Hardware: TX-2Console Memory Bank6
  • 7. Light Pen7
  • 8. SketchPad: Video8
  • 9. Sketchpad innovationsSketchpad was a seminal work which introducedseveral fundamental concepts in Graphics and CAD9
  • 10. Sketchpad innovationsFirst interactive Graphical User Interface10
  • 11. The entire drawing is specified using a RINGstructureRecursively composed of objects, along withtransformations (move, scale, rotate)Specifies entire topology as well as constraintsPrecursor to modern Scene Graph11Sketchpad: Innovations: Hierarchical Storage

  • 19. SketchpadA display connected to a digital computer gives us achance to gain familiarity with concepts notrealizable in the physical world. It is a looking glassinto a mathematical wonderland.- Ivan Sutherland19
  • 20. Sutherland realized the clear distinctionbetween generic and specific code20Sketchpad: Programming Style
  • 21. Sketchpad: Programming StyleGeneral  Parent classSpecific  Child class
  • 22. 22Sketchpad: Object Oriented ProgrammingClasses and Instances“Master Drawing”  “Instance Drawing"
  • 23. General (applicable to all entities)o scale()o translate()o rotate()Specific (ex. circle, line, point)o draw()o constrain()Precursor to Object Oriented Programming23Sketchpad: Programming Style
  • 24. 24Sketchpad  Object Oriented ProgrammingAt Utah sometime after Nov 66 when, influenced bySketchpad, Simula, the design for the ARPAnet, the Burroughs B5000, andmy background in Biology and Mathematics, I thought of an architecturefor programming. It was probably in 1967 when someone asked me what Iwas doing, and I said: "Its object-oriented programming".- Alan Kay, Creator of SmallTalk,2003 Turing Award Recipient
  • 25. The Ultimate Display - 1965Sutherland headed IPTO - ARPAOutlined his vision of the ultimate displayo Using this display, a person could look into avirtual world that would appear as real as thephysical world the user lived ino Visionary predictions, most of which have cometrue25
  • 26. Head Mounted DisplayFirst Virtual Reality (VR) and AugmentedReality (AR) systemFirst Head Mounted Display (HMD) coupledwith graphics- Present the user with a perspective imagewhich changes as he moves- Surround the user with displayed 3Dinformation26
  • 27. The Sword of Damocles27
  • 28. Head Mounted DisplayRealtime graphics system, with dedicatedgraphics hardware (matrix multiplier)Birth of the graphics pipelineWorked with Bob Sproull28
  • 29. HMD System29
  • 30. 30The Camera Analogy
  • 31. HMD pipelineThe matrix multiplier unit is aseparate, dedicated hardware systemo Matrix multiplication, perspective division andclippingo Each module is an independently timed digitaldevice with its own input and outputsynchronizationo Vertex data streams through the pipeline31
  • 32. HMD System32
  • 33. 33Vertex Transformation Pipeline: OpenGLHomogeneous co-ordinates, 4x4 matrices, transforms,perspective projection, clipping… all there in this 1968 paper!
  • 34. Modern Graphics Pipeline34
  • 35. The Sword of DamoclesFirst Augmented Reality System“half-silvered mirrors in the prisms throughwhich the user looks allow him to see both theimages from the cathode ray tubes and objectsin the room simultaneously”Super-imposition of real-world imagery withgraphical imagery35
