6 MIT media lab camera culture CameraBokode CameraBokode Shop keeper’s ‘base’ station Consumer Bokode: Micro-commerce via Camera Phones

7 7 Beyond Multi-touch: Mobile Laptops Mobile

8 8 Converting LCD Screen = large Camera for 3D Interactive HCI and Video Conferencing Matthew Hirsch, Henry Holtzman Doug Lanman, Ramesh Raskar Siggraph Asia 2009 BiDi Screen

9 9 Design Vision Object Collocated Capture and Display Bare Sensor Spatial Light Modulator

10 10 Touch + Hover using Depth Sensing LCD Sensor

11 11 Overview: Sensing Depth from Array of Virtual Cameras in LCD

12 Can you ‘see’ around a corner ?

13 Depth –Geometry –Surface Orientation –Occlusion Material –Spectrum Femto-Photography FemtoFlash UltraFast Detector Computational Optics Serious Sync

14 Can you look around a corner ? Kirmani, Hutchinson, Davis, Raskar 2009 ICCV’2009, Oct 2009 in Kyoto

15 Femtosecond Laser as Light Source Pico-second detector array as Camera

16 Key Idea: Use Third and Higher bounces We made use of Proximity prior, Euclidean distance constraints and Estimated visible patch distances to label third bounces

17 T3T3 dHdH = O3O3 Third bounce Time of arrival onsets Relate time onsets to scene distances using the Second Order Distance transform T 3 + Distance TransformHidden inter-patch distances Distance Uncertainty
