Abstract: A method comprises receiving, by a computing device, a video stream comprising a first presentation interface, separating the received video stream from the first presentation interface, processing the separated video stream, and presenting the processed video stream on a display device in the absence of the first presentation interface.

Abstract: A method of conducting a collaborative event comprises receiving, by at least one computing device, a shared file from a participant computing device joined to the collaborative event; displaying the shared file on at least one interactive board in communication with the at least one computing device during the collaborative event; and sending an updated shared file from the at least one computing device to the participant computing device, the updated shared file comprising at least user input injected into the received shared file using the at least one interactive board.

Abstract: Systems, devices, and methods are provided for establishing bidirectional communication among computing devices. In some aspects, a wireless access establishes a communication link with a first computing device. The access point identifies, based on communications between the first computing device and the access point, an application executed on the first computing device. The access point determines that a second computing device that is in communication with the access point can present outputs generated by the application and generate input events usable by the application. The access point transmits a notification to the first computing device that the second computing device is accessible via the access point. The access point can transmit the notification based on determining that the second computing device can present the outputs and generate the input events that are usable by the application.

Abstract: A method for grouping graphical objects, comprises presenting graphical objects on a display surface and in the event that the graphical objects at least partially overlap, grouping the graphical objects.

Abstract: A multi-monitor computer system includes a plurality of display devices communicating with at least one computing device executing an application management procedure. The application management procedure enables an application window available on one display device to be moved entirely to another display device by selecting the other display device from a dialog box displayed in response to a pointer-dragging input gesture on the application window.

Abstract: A tool tray for an interactive input system comprises a housing having an upper surface defining at least one receptacle sized to receive a tool for interacting with an interactive surface, a sensor configured to detect the presence of the tool within the receptacle and at least one display in communication with the sensor. The display is configured to present a pointer attribute selection screen upon removal of the tool from the receptacle.

Abstract: An interactive input system comprises an interactive surface, an illumination source projecting light onto the interactive surface such that a shadow is cast onto the interactive surface when a gesture is made by an object positioned between the illumination source and the interactive surface, at least one imaging device capturing images of a three-dimensional (3D) space in front of the interactive surface, and processing structure processing captured images to detect the shadow and object therein, and determine therefrom whether the gesture was performed within or beyond a threshold distance from the interactive surface and execute a command associated with the gesture.

Abstract: A method of presenting data gathered by a participant response system, comprising obtaining spatial information for participants; collecting response data from the participants and generating result data; overlaying the result data on a map image in accordance with the obtained spatial information to form a data map; and displaying the data map.
