Abstract: A computer-implemented method (300) for extracting content (302) from a physical writing surface (304), the method (300) comprising the steps of: (a) receiving a reference frame (306) including image data relating to at least a portion of the physical writing surface (304), the image data including a set of data points; (b) determining an extraction region (308), the extraction region (308) including a subset of the set of data points from which content (302) is to be extracted; (c) extracting content (302) from the extraction region (308) and writing the content (302) to a display frame (394); (d) receiving a subsequent frame (406) including subsequent image data relating to at least a portion of the physical writing surface (304), the subsequent image data including a subsequent set of data points; (e) determining a subsequent extraction region (408), the subsequent extraction region (408) including a subset of the subsequent set of data points from which content (402) is to be extracted; and (f) extracting

Abstract: A server and computer implemented method for sharing physical writing actions, the method comprising the steps of: detecting, at each of a plurality of computing devices associated with a meeting, one or more physical writing actions being performed on physical writing surfaces; generating writing signals based on the physical writing actions; transmitting the generated writing signals to a server; forwarding, via the server, the writing signals for receipt at the plurality of computing devices associated with the meeting; and each computing device outputting a representation of the physical writing actions.
