Abstract: A dynamic media menu that comprises a media carousel to present collections of media content, and an “Augmented-Reality (AR) bar” to receive inputs to identify a media category.

Abstract: A media curation system configured to perform operations that include, capturing an image at a client device, wherein the image includes a depiction of an object, identifying an object category of the object based on the depiction of the object within the image, accessing media content associated with the object category within a media repository, generating a presentation of the media content, and causing display of the presentation of the media content within the image at the client device.

Abstract: Systems, devices, media, and methods are presented for object detection and inserting graphical elements into an image stream in response to detecting the object. The systems and methods detect an object of interest in received frames of a video stream. The systems and methods identify a bounding box for the object of interest and estimate a three-dimensional position of the object of interest based on a scale of the object of interest. The systems and methods generate one or more graphical elements having a size based on the scale of the object of interest and a position based on the three-dimensional position estimated for the object of interest. The one or more graphical elements are generated within the video stream to form a modified video stream. The systems and methods cause presentation of the modified video stream including the object of interest and the one or more graphical elements.

Abstract: A music based video game provides an auxiliary palm input on an associated guitar shaped video game controller. In some embodiments, the auxiliary palm input is positioned near a strum input on a body of the guitar shaped video game controller, allowing for simultaneous operation of both the strum input and the auxiliary palm input with one hand. In some embodiments, the auxiliary palm input modifies audio outputs generated in the music based video game. In some embodiments, the auxiliary palm input triggers an alternate game mode, for example, a bonus mode, during video game play of the music based video game.

Abstract: Music video games provide configurable instruments and/or recording functions. In some embodiments users may select an instrument or play, and also select desired characteristics of the instrument. The desired characteristics may include selection of a chord or selection of effects associated with the type of musical instrument. In some embodiments users may record tracks of music using their simulated musical instrument controllers.
