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. ## Claims ### Claim 1 A server implemented method for sharing physical writing actions, the method comprising the steps of: receiving, at a server, generated writing signals associated with a meeting between two or more computing devices, wherein the generated writing signals are associated with the detection of physical writing actions by a camera associated with a first of the two or more computing devices; and forwarding, from the server to at least a second of the computing devices, the generated writing signals associated with the meeting. ### Claim 2 (depends on 1) The method of claim 1 further comprising the step of: detecting, at the first computing device, the physical writing actions in a defined area. ### Claim 3 (depends on 1) The method of claim 1, further comprising the steps of: detecting within the image a plurality of edges of a writing surface; defining a boundary of the writing surface based on the detected edges; defining a plurality of areas within the defined boundary of the writing surface; and analyzing the image to detect the physical writing actions in one or more of the defined areas. ### Claim 4 (depends on 1) The method of claim 1, further comprising the steps of: receiving a first writing signal from the first computing device at a server, wherein the first writing signal is based on a first physical writing action being performed on a first physical writing surface detected by the camera at the first computing device; receiving a second writing signal from the second computing device at a server, wherein the second writing signal is based on a second physical writing action being performed on a second physical writing surface detected by a camera associated with the second computing device; and forwarding, the first writing signal from the server to the second computing device and forwarding the second writing signal from the server to the first computing device, to enable the first computing device and the second computing device to output a representation of both of the detected first and second physical writing actions. ### Claim 5 (depends on 1) The method of claim 1, further comprising the steps of: transmitting to a first computing device all the writing signals of the remaining computing devices to enable the first computing device to output a representation of the physical writing actions based on its own generated writing signal and the received writing signals, and transmitting to one or more of the plurality of computing devices the writing signals from the first computing device only, to enable the one or more of the plurality of computing devices to output a representation of the physical writing actions based on the one or more of the plurality of computing devices own generated writing signal and the writing signals received from the first computing device only. ### Claim 6 (depends on 1) The method of claim 1, wherein the server is located on a publically accessible network. ### Claim 7 (depends on 1) The method of claim 1, wherein the step of forwarding the writing signals further comprises the step of: forwarding to each of the plurality of computing devices all writing signals that have been generated by all of the other computing devices. ### Claim 8 (depends on 7) The method of claim 7, wherein the writing signal generated by a particular computing device is not forwarded to that particular computing device. ### Claim 9 (depends on 1) The method of claim 1, wherein the generated writing signals are received by the server in real time. ### Claim 10 (depends on 1) The method of claim 1, further comprising the step of: storing each of the writing signals at the server for retrieval by the plurality of computing devices after completion of the meeting. ### Claim 11 (depends on 1) The method of claim 1, wherein the writing signals are part of a personalised workspace associated with each computing device associated with the meeting. ### Claim 12 (depends on 1) The method of claim 1, further comprising the step of the server recording the physical writing actions that occur in a meeting for a particular user. ### Claim 13 (depends on 1) The method of claim 1, further comprising the steps of: recording, at the server, all physical writing actions associated with a host of a meeting and attendees of the meeting; and sending, to a computing device associated with the host of meeting, all the recorded physical writing actions. ### Claim 14 (depends on 1) The method of claim 1, further comprising the steps of: recording, at the server, all physical writing actions associated with a host of a meeting and attendees of the meeting; and sending, to a computing device associated with a first attendee of the meeting, a combination of the host's recorded physical writing actions and the physical writing actions of the first attendee of the meeting to the first attendee, while excluding the physical writing actions of other attendees. ### Claim 15 (depends on 1) The method of claim 1, further comprising the steps of recording personalised audio signals in addition to the physical writing actions. ### Claim 16 (depends on 1) The method of claim 1, wherein the generated writing signals are forwarded to enable the two or more computing devices to collaborate based on the physical writing actions. ### Claim 17 (depends on 1) The method of claim 1, wherein the first of the two or more computing devices is a computer system, a desktop computer, a mobile phone, a smartphone, or a tablet. ### Claim 18 (depends on 1) A server arranged to perform the method of claim 1. ### Claim 19 (depends on 1) A computer program product including a computer readable medium having recorded thereon a computer program for implementing the method of claim 1.
