Examples disclosed herein relate to detecting misalignment of a touch sensitive mat. Examples include detecting corners of the touch sensitive mat, determining a set of reference corners, performing a comparison of the detected corners of the mat with the set of reference corners, and determining a level of misalignment based on the comparison.

Misalignment detection

Examples disclosed herein relate to identifying a target touch region of a touch-sensitive surface based on an image. Examples include a touch input detected at a location of a touch-sensitive surface, an image representing an object disposed between a camera that captures the image and the touch-sensitive surface, identifying a target touch region of a touch-sensitive surface based on an image, and rejecting the detected touch input when the location of the detected touch input is not within any of the at least one identified target touch region of the touch-sensitive surface.

Identifying a target touch region of a touch-sensitive surface based on an image

Examples disclosed herein relate to determining a segmentation boundary based on images representing an object. Examples include an IR image based on IR light reflected by an object disposed between an IR camera and an IR-absorbing surface, a color image representing the object disposed between the color camera and the IR-absorbing surface, and determining a segmentation boundary for the object.

Determining a segmentation boundary based on images representing an object

A method performed by a system. The method includes automatically generating an interactive window on at least a portion of a display, the interactive window having a first size corresponding to a first pattern on the display. The method further includes automatically expanding the interactive window to a second size in response to a second pattern on the display to enclose the first pattern and the second pattern in the interactive window.

Interactive window

An image rendition and capture method includes rendering a first image on a surface using a first set of wavelength ranges of light. While the first image is being rendered, a second image is captured using a second set of wavelength ranges of light but not the first set. The second image is of the surface on which the first image is being rendered.

Image rendition and capture

Embodiments of the present invention are directed to a visual-collaborative system enabling geographically distributed groups to engage in face-to-face, interactive collaborative video conferences. In one aspect, a visual-collaborative system comprises a display screen, a camera system, and a projector. The display screen has a first surface and a second surface, and the camera system is positioned to capture images of objects through the display screen. The projector is positioned to project images onto a projection surface of the display screen, wherein the projected images can be observed by viewing the second surface. The system includes a first filter disposed between the camera and the first surface, where the first filter passes light receives by the camera but substantially blocks the light that is produced by the projector.

Systems for capturing images through a display

Disclosed herein are multimedia-conferencing systems and methods enabling local participants to hear remote participants from the direction the remote participants are rendered on a display. In one aspect, a method includes a computing device receives a remote participant's image and sound information collected at a remote site. The remote participant's image is rendered on a display at a local site. When the local participant is in close proximity to the display, sounds generated by the remote participant are played over stereo loudspeakers so that the local participant perceives the sounds as emanating from the remote participant's location rendered on the display.
