Collaborative presentation system

On a collaborative presentation system, a method of providing a collaborative presentation, the method comprising:

• retrieving a presentation file that is executed to display a presentation on a display device;
• receiving, from an image sensor, image frames including images of the display device and a presenter;
• extracting the presenter from the image frames to generate an extracted presenter image;
• adjusting an appearance of the extracted presenter image to form an adjusted presenter image;
• overlaying the adjusted presenter image onto the presentation to generate an updated presentation file, the updated presentation file being executable to display the presentation overlaid with the adjusted presenter image, wherein adjusting the appearance of the extracted presenter image includes cropping the adjusted presenter image such that boundaries of the adjusted presenter image as overlaid onto the presentation are within a threshold distance of boundaries of the presentation or boundaries of the display;
• transmitting, via a network interface, the updated presentation file to a remote presentation participant device;
• receiving, via the network interface, collaboration input from the remote presentation participant device;
• and
• adjusting the presentation as displayed on the display device based on the received collaboration input.

A collaborative presentation system comprising:

• a display device;
• an image sensor configured to image a region including the display device;
• a network interface;
• a logic device;
• and
• a storage device holding instructions executable by the logic device to:
• retrieve a presentation file that is executed to display a presentation on the display device;
• receive plurality of image frames from the image sensor, each of the image frames including an image of the display device and an image of the presenter;
• for each image frame of the plurality of received image frames:
• extract the presenter from the image frames to generate an extracted presenter image;
• adjust an appearance of the extracted presenter image to form an adjusted presenter image;
• align the adjusted presenter image with a displayable element of the presentation that is displayed on the image of the display device in that image frame;
• crop the adjusted presenter image such that the adjusted presenter image, as aligned with the displayable element of the presentation, shares boundaries with the presentation as displayed on the display device;
• overlay the cropped adjusted presenter image onto the displayable element of the presentation that is displayed on the image of the display device in that image frame to generate an updated presentation file, wherein adjusting the appearance of the extracted presenter image includes cropping the adjusted presenter image such that boundaries of the adjusted presenter image as overlaid onto the presentation are within a threshold distance of boundaries of the presentation or boundaries of the display;
• and
• transmit, via the network interface, the updated presentation file to a remote presentation participant device, the updated presentation file being executable to display the presentation overlaid with each cropped adjusted presenter image.

A collaborative presentation system comprising:

• a display device;
• an image sensor configured to image a region including the display device, wherein the image sensor comprises a depth image sensor and an RGB camera;
• a network interface;
• a logic device;
• and
• a storage device holding instructions executable by the logic device to:
• retrieve a presentation file that is executed to display a presentation on the display device, the presentation file including one or more displayable elements;
• receive a plurality of image frames from the image sensor, each image frame including an image of the display device, an image of a currently-displayed displayable element of the presentation, and an image of a presenter;
• for each image frame of the plurality of received image frames:
• extract the image of the presenter from the image frame to generate an extracted presenter image, wherein extracting the presenter comprises generating a depth image of the presenter based on image data from the depth image sensor and overlaying the depth image with an RGB overlay based on image data from the RGB camera,
• adjust an appearance of the extracted presenter image to form an adjusted presenter image, and
• overlay the adjusted presenter image over the currently-displayed displayable element of the presentation;
• generate an updated presentation file, the updated presentation file being executable to display the one or more displayable elements of the presentation overlaid with each adjusted presenter image;
• and
• transmit, via the network interface, the updated presentation file to a remote presentation participant device.
