The access code can be a two dimensional graphic or QR code that can be easily captured by a camera unit of the secondary device. Once captured, additional content related to the running application can be identified and displayed on the secondary device. ## Claims ### Claim 1 A computer-implemented method comprising: capturing, by a first computing device, an access code generated by and presented on a display of a second computing device; based on the access code, decoding, by the first computing device, application metadata describing a current state of an application operating on the second computing device, wherein the application metadata is collected by the second computing device in response to the second computing device detecting a help event triggered while application content is being displayed and interacted with on a display of the second computing device, wherein the application metadata identifies the application; retrieving, by the first computing device, additional application content based on an identification of the application and the current state of the application, the additional application content is related to assisting a user with the application; and presenting, by the first computing device, the additional content on the display of the first computing device. ### Claim 2 (depends on 1) The computer-implemented method of claim 1, wherein the help event is associated with an error generated during execution of the application. ### Claim 3 (depends on 1) The computer-implemented method of claim 1, wherein the access code includes a plurality of fields configured to store application metadata. ### Claim 4 (depends on 1) The computer-implemented method of claim 1, wherein retrieving the additional application content comprises retrieving the additional content from a storage of the first computing device. ### Claim 5 (depends on 4) The computer-implemented method of claim 4, wherein the additional application content is presented on the display of the first computing device at the same time as the application content is being presented on the display of the second computing device. ### Claim 6 (depends on 1) The computer-implemented method of claim 1 further comprising sending, by the first computing device, a signal to the second computing device indicating that the first computing device has read the access code displayed on the display of the second computing device. ### Claim 7 (depends on 1) The computer-implemented method of claim 1, wherein the access code is an audible noise outputted by the second computing device through a speaker of the second computing device, wherein capturing the access code comprises using a microphone of the first computing device to capture the access code. ### Claim 8 A non-transitory computer readable storage medium storing a program executable by at least one processing unit of a first computing device, the programs comprising sets of instructions for: capturing an access code generated by and presented on a display of a second computing device; based on the access code, decoding application metadata describing a current state of an application operating on the second computing device, wherein the application metadata is collected by the second computing device in response to the second computing device detecting a help event triggered while application content is being displayed and interacted with on a display of the second computing device, wherein the application metadata identifies the application; retrieving additional application content based on an identification of the application and the current state of the application, the additional application content is related to assisting a user with the application;
