A first electronic device receives information relating to modification made to an augmented reality presentation at a second electronic device, and the first electronic device modifies the first augmented reality presentation in response to the information. ## Claims ### Claim 1 A method, comprising: during a collaborative augmented reality session that involves multiple electronic devices capturing a physical target or a replica of the physical target, receiving, by a computer, modification information on collaborative modifications made at the multiple electronic devices; storing, by the computer, the modification information as state information regarding the collaborative augmented reality session; determining, by the computer, that an additional electronic device has captured a physical target or a replica of the physical target that is the same as the physical target or the replica of the physical target captured by the multiple electronic devices; connecting, by the computer, the additional electronic device to the collaborative augmented reality session; and providing, by the computer, the state information regarding the collaborative augmented reality session to the additional electronic device. ### Claim 2 (depends on 1) The method according to claim 1, wherein the determining comprises receiving an image or a video from the additional electronic device and wherein the image or the video received from the additional electronic device contains a perspective of the physical target or the replica of the physical target. ### Claim 3 (depends on 2) The method according to claim 2, wherein the perspective of the physical target or the replica of the physical target is different from perspectives of the physical target or the replica of the physical target seen by the multiple electronic devices. ### Claim 4 (depends on 1) The method according to claim 1, wherein the computer comprises one of the multiple electronic devices or an augmented reality server. ### Claim 5 (depends on 1) The method according to claim 1, wherein the computer comprises one of the multiple electronic devices configured as an augmented reality server. ### Claim 6 (depends on 1) The method according to claim 1, further comprising: determining that no additional electronic device has been added to the collaborative augmented reality session; and waiting for information reporting a modification made at any electronic device in the collaborative augmented reality session. ### Claim 7 (depends on 1) The method according to claim 1, further comprising: tracking movements of the multiple electronic devices based on detected poses of the multiple electronic devices relative to the physical target or the replica of the physical target captured by the multiple electronic devices. ### Claim 8 A system, comprising: a processor; a non-transitory computer-readable medium; and instructions stored on the non-transitory computer-readable medium and translatable by the processor for: during a collaborative augmented reality session that involves multiple electronic devices capturing a physical target or a replica of the physical target, receiving modification information on collaborative modifications made at the multiple electronic devices; storing the modification information as state information regarding the collaborative augmented reality session; determining that an additional electronic device has captured a physical target or a replica of the physical target that is the same as the physical target or the replica of the physical target captured by the multiple electronic devices; connecting the additional electronic device to the collaborative augmented reality session; and providing the state information regarding the collaborative augmented reality session to the additional electronic device. ### Claim 9 (depends on 8) The system of claim 8, wherein the determining comprises receiving an image or a video from the additional electronic device and wherein the image or the video received from the additional electronic device contains a perspective of the physical target or the replica of the physical target. ### Claim 10 (depends on 9) The system of claim 9, wherein the perspective of the physical target or the replica of the physical target is different from perspectives of the physical target or the replica of the physical target seen by the multiple electronic devices. ### Claim 11 (depends on 8) The system of claim 8, wherein the system comprises one of the multiple electronic devices or an augmented reality server. ### Claim 12 (depends on 8) The system of claim 8, wherein the system comprises one of the multiple electronic devices configured as an augmented reality server. ### Claim 13 (depends on 8) The system of claim 8, where the instructions are further translatable by the processor for: determining that no additional electronic device has been added to the collaborative augmented reality session; and waiting for information reporting a modification made at any electronic device in the collaborative augmented reality session. ### Claim 14 (depends on 8) The system of claim 8, where the instructions are further translatable by the processor for: tracking movements of the multiple electronic devices based on detected poses of the multiple electronic devices relative to the physical target or the replica of the physical target captured by the multiple electronic devices. ### Claim 15 A computer program product comprising a non-transitory computer-readable medium storing instructions translatable by a processor for: during a collaborative augmented reality session that involves multiple electronic devices capturing a physical target or a replica of the physical target, receiving modification information on collaborative modifications made at the multiple electronic devices; storing the modification information as state information regarding the collaborative augmented reality session; determining that an additional electronic device has captured a physical target or a replica of the physical target that is the same as the physical target or the replica of the physical target captured by the multiple electronic devices; connecting the additional electronic device to the collaborative augmented reality session; and providing the state information regarding the collaborative augmented reality session to the additional electronic device. ### Claim 16 (depends on 15) The computer program product of claim 15, wherein the determining comprises receiving an image or a video from the additional electronic device and wherein the image or the video received from the additional electronic device contains a perspective of the physical target or the replica of the physical target. ### Claim 17 (depends on 16) The computer program product of claim 16, wherein the perspective of the physical target or the replica of the physical target is different from perspectives of the physical target or the replica of the physical target seen by the multiple electronic devices. ### Claim 18 (depends on 15) The computer program product of claim 15, wherein the processor is part of one of the multiple electronic devices or an augmented reality server. ### Claim 19 (depends on 15) The computer program product of claim 15, where the instructions are further translatable by the processor for: determining that no additional electronic device has been added to the collaborative augmented reality session;
