US Patent 9832441 Supplemental content on a mobile device

Methods, systems, devices, and software are described for providing supplemental content for presentation on a mobile device that identifies a video and a portion within the video. In one embodiment, a system includes a mobile device with an integrated video camera that tracks a display playing a movie. The mobile device automatically identifies the current scene in the movie and then accesses supplemental non-video content related to the identified scene. The accessed supplemental non-video content (e.g., audio, tactile, olfactory data) is then presented to the user at the same time the movie is played.
