A method, article of manufacture, and apparatus for tracking user interactions comprising receiving a first request associated with a first user, to exchange a communication with a second user about one of a plurality of elements of a web-page, wherein the plurality of elements includes at least one of graphical elements and textual elements; in response to the first request, exchanging a communication between the first user and the second user; capturing the communication; storing an interaction object comprising the communication, wherein storing includes associating the interaction object with the one of the plurality of elements of the web-page; and serving a modified version of the web-page to a third user; wherein the modified version specifies the interaction object being associated with the one of the plurality of elements of the web-page.

Framework for persistent user interactions within web-pages

A method of matching one or more software plug-ins to a user, the method including: defining one or more trigger events based on one or more actions of an application; monitoring a use of the application for the one or more trigger events; generating a suggestion of one or more plug-ins based on the use of the application; and generating a notification including the suggestion.

An apparatus and method for stereoscopic 3D image projection and viewing using a single projection source, alternating polarization, and passive eyewear. This approach is applicable to frame sequential video created using existing 3D graphics APIs, as well as other video signal formats, and is compatible with existing digital light processor (DLP) technology for both front and rear projection systems. An alternating polarizer filter actuator in the form of a closed feedback loop is used to modulate the projected image. A preferred embodiment enables an existing DLP projection system to be enhanced with 3D capability.

An apparatus and method for stereoscopic 3D image projection and viewing using a single projection source, polarization modulation, and passive eyewear. This approach is applicable to frame sequential video created using existing 3D graphics APIs, as well as other video signal formats, and is compatible with existing digital light processor (DLP) technology for both front and rear projection systems. An alternating polarizer is used to modulate the projected image, and an electronic control circuit is described which can stabilize the alternating polarizer in both frequency and phase lock with a DLP visual signal (as an alternate embodiment, a frequency lock with a fixed phase offset may be employed). A preferred embodiment enables an existing DLP projection system to be enhanced with 3D capability, while an alternate embodiment allows this capability to be integrated into the design of new DLP based projection systems.

Noise immune optical encoder for high ambient light projection imaging systems

A stereo 3D projector with the ability to provide the native lumen output of the projector when not in 3D mode. This is accomplished by using two rotating polarizing filters at least partially overlapping, each with at least two or more segments, some of which are fully transparent and at least some of which are polarized linearly or circularly.

Lumen optimized stereo projector using a plurality of polarizing filters

A peripheral device is coupled to a system bus of an apparatus via a system bus compatible cable, and transmits to an operating system a request to transmit to the output multiple image stream 3D video data and a request to access a video subsystem for monitoring a status of page flip signals. The peripheral device transmits sync signals to at least one output of the peripheral device representing the page flip signals detected in response to monitoring page flip signal status. The apparatus transmits the multiple image stream 3D video data to the output. The multiple image stream 3D video data is received at a stereographic projection apparatus input. Each stream data contains a plurality of frames. The stereographic projection apparatus comprises an alternating polarizing filter, synced with the alternately projecting images, for separately filtering images from each of the image stream 3D video data at different polarization angles.

A method and apparatus for extracting synchronization information at the output of a projection apparatus, without modifying its rotating color segmented filter wheel or drive electronics. Three photodiodes, each with a different principle color filter, is placed at the projector output to detect output of the different colors in the filter wheel. An exclusive OR circuit is used to detect white light passing through the filter wheel.

Method to synchronize stereographic hardware to sequential color rendering apparatus

A 3D stereographic projection apparatus comprises an input for receiving stereographic image data that includes sync signals corresponding to image streams in the image data. A digital light projector projects the stereographic image data. A motor driven rotating filter has a marker disposed thereon positioned in the path of the projected stereographic image data. The motor driven rotating filter separately polarizes the image streams in the stereographic image data. A motor drive circuit, coupled to the input, receives the sync signals and synchronizes a rotation of the filter with the sync signals. A tach sensor, comprising a light transmitter and detector coupled to the rotating filter, detects the marker and outputs marker signals indicating that the marker is detected.
