Abstract: Disclosed are various embodiments for initiating execution of an application based at least in part on an identification of the object in an image, video, or other graphical representation of the object. A graphical representation of an object is obtained using an image capture device. The object in the graphical representation is identified along with a list of applications associated with the identified object. A user interface is then rendered that allows the user to execute or install one or more of the applications associated with the identified object.

Abstract: Disclosed are various embodiments of a voice-based grading assistant. A first computing device can receive a voice command from a second computing device that identifies an assignment, a student, and a grade for the student for the assignment. The voice command is then processed by the first computing device to identify the assignment, the student, and the grade. Subsequently, the first computing device can enter a grade for the student for the assignment in a data store.
