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.

Compared with the prior art, the present invention adopts the interconnection and intercommunication of multiple terminals such as electronic whiteboards, tablet computers, computers, and projectors through the Internet, which changes the way teachers and students interact and improves the frequency of interaction in class; The data in the answering process is counted in real time, and the system provides comprehensive teaching materials to realize resource sharing and improve teaching efficiency.

Remote collaboration, particularly synchronous collaboration, between parties in separate locations can be enhanced by providing the opportunity for both parties to “write” on a paper medium or other surface. This is particularly useful in an instructor/student tutoring session. Both the student and instructor may have workstations with video conferencing and screen-sharing capabilities. Advantageously the student station has a camera such as a document camera for imaging an object that the student may write on, for example, writing on paper with a pen. The instructor station may have an interactive whiteboard and a projector. Video conferencing capabilities are used to transmit an image of the student writing to the instructor which image will be displayed to the instructor through projection onto an interactive whiteboard surface. The interactive whiteboard allows the instructor to “virtually” mark the projection of the paper using for example a stylus and an infrared sensor. Annotation software at the instructor's station creates a representation of the instructor's “writing.” The annotation software also may add the representation of the writing to the instructor's projection. The representation of the writing and the representation of the image are provided to the student station by the screen-sharing software and the combined document image and annotations may be displayed to the student creating the effect of the remote instructor writing on a paper locally imaged by the document station.

There is disclosed a method for controlling a computer system, which computer system is adapted to receive touch data and non-touch data, the method comprising the steps of: receiving input data from an interactive display surface; and selectively delivering the input data from the interactive display surface to an interface of an operating system of the computer system as either touch data or non-touch data.

A cross-platform conferencing interface includes a graphical user interface (GUI) that displays multiple conferencing options, including a web conferencing option. Beginning at a home screen of the conferencing interface, a user can connect a web conference call through one of multiple web conference applications, or providers, in as few as two clicks. A first click can cause a web conference screen usable with multiple different conferencing applications to be displayed. The second click can initiate a call to a selected contact associated with the particular web conferencing application. The web conference screen acts as a front-end application program interface (API) for the web conferencing application or provider, but the call is connected using the application's resources. The interface can be implemented as a dedicated conferencing device that provides video conferencing, audio conferencing, web conferencing, and an interactive whiteboard.

The invention provides a wireless interaction electronic whiteboard conference system. The wireless interaction electronic whiteboard conference system comprises an electronic whiteboard and user side communication equipment, wherein a point-to-point wireless network connection is realized through the electronic whiteboard and the user side communication equipment based on a p2p protocol; the electronic whiteboard is compatible with at least two wireless transmission protocol standards; the user side communication equipment automatically searches for and is connected with the electronic whiteboard according to the p2p protocol; the user side communication equipment sends a message to the electronic whiteboard after the connection; and the electronic whiteboard determines a protocol standard supported by the user side communication equipment according to a content format of the message, and calls a protocol standard which is matched with the user side communication equipment to realize wireless connection access. Through adoption of the wireless interaction electronic whiteboard conference system, real-time content sharing among a plurality of pieces of equipment can be realized in a projection-video conference system anytime and anywhere, and display content of equipment of corresponding different types can be received and directly displayed on the electronic whiteboard, so that real-time annotation and explanation can be realized, and sharing, communication and discussion of a conference become more convenient and effective.

A computer (host), which is communicating with an interactive whiteboard projector (client) through a remote desktop connection, launches third-party applications supporting multiple mice (i.e. drawing pens) and provides these applications with virtual mouse device and input event signals for each pen device connected on the projector. The applications will behave as if the host system were configured with multiple installed mice, though no added driver or physical connected hardware is present.
