5. A computer-implemented method comprising: under control of one or more computer systems configured with executable instructions, obtaining image information using a camera of a computing device; identifying an event associated with the image information; analyzing text associated with the event using at least one of a computer vision algorithm or an optical character recognition algorithm to identify the text in the image information; determining at least one action available to a user, the action being related to the event; and causing the computing device to perform the at least one action related to the event.
