The systems may include interactive whiteboard (IWB) systems participating in a collaborative session. The position of an object (e.g., a user) at a first IWB system may be tracked and displayed at a second IWB system located remotely from the first IWB system. | 09-13-2012 |
20120233615 | AUTOMATICALLY PERFORMING AN ACTION UPON A LOGIN - Techniques for automatically performing one or more actions responsive to a successful login. In one embodiment, an action automatically performed responsive to the login uses content created prior to the login. | 09-13-2012 |
20120280948 | INTERACTIVE WHITEBOARD USING DISAPPEARING WRITING MEDIUM - Techniques for enabling interactive whiteboard functionality using a disappearing writing medium. In one set of embodiments, an image of a surface can be received, where the image can include one or more physical marks made on the surface by a user. The physical marks can be made using a writing medium that is configured to disappear over time. Electronic representations of the physical marks can be generated based on the image, and the electronic representations can be displayed on the surface. The electronic representations can be displayed such that they visually replace the physical marks made on the surface as the physical marks fade and disappear. | 11-08-2012 |
20130229332 | ASSOCIATING STROKES WITH DOCUMENTS BASED ON THE DOCUMENT IMAGE - A method and apparatus is disclosed herein for associating strokes with a document image. In one embodiment, the method comprises capturing strokes written on a screen over a first document image while the document image is being displayed, associating captured stroke data of the captured strokes with underlying image patches of the document image being displayed, determining that a second document image is being displayed on the screen, determining whether one or more image patches of the second document image, or parts thereof, had previously been associated with captured stroke data, and drawing one or more previously captured strokes, or portions thereof, on image patches of the second document image based on results of determining whether one or more image patches of the second document image, or parts thereof, had previously been associated with captured stroke data. | 09-05-2013 |
20130229333 | AUTOMATIC ENDING OF INTERACTIVE WHITEBOARD SESSIONS - A method and apparatus is disclosed herein for automatically ending an interactive device session. In one embodiment, the system comprises a memory; and a processor coupled to the memory and operable to: log out a user, delete locally stored data created during a session, and place one or more system hardware components in a reduced power consumption state based on: occupancy sensor data indicating presence or absence of one or more individuals in proximity to an occupancy sensor, and activity information associated with a display surface. | 09-05-2013 |

The system includes a controller, a phase image module, a presentation module and a phase determination module. The controller receives projector geometry parameters. A phase image module determines a plurality of sinusoidal images where a constant phase represents a flat plane in a three-dimensional space based on the projector geometry parameters. A presentation module projects the plurality of sinusoidal images to be captured by a camera. The phase determination module determines a phase value at a camera pixel. The phase determination module determines an intersection between the flat plane of the phase value and the camera pixel to identify a ray-plane intersection. | 05-01-2014 |
