Abstract: Described is a user interface that displays a representation of a stereo scene, and includes interactive mechanisms for changing parameter values that determine the perceived appearance of that scene. The scene is modeled as if viewed from above, including a representation of a viewer's eyes, a representation of a viewing screen, and an indication simulating what each of the viewer eyes perceives on the viewing screen. Variable parameters may include a vergence parameter, a dolly parameter, a field-of-view parameter, an interocular parameter and a proscenium arch parameter.

Abstract: Disclosed in some examples is a method of providing assistance to a consumer comprising authenticating with a shopping service over a network using a network adapter; downloading a shopping list from the shopping service over the network using a network adapter; displaying the shopping list to the user on a display screen, the shopping list comprising a name of an item, wherein each item in the shopping list may be displayed as a tile, wherein each tile is arranged in a series of rows and columns; receiving an input identifying one or more changes to the shopping list; processing the input using a computer processor; and sending the one or more changes to the shopping service over the network using the network adapter.

Abstract: A system, method, and computer readable medium is provided to track consumer engagement with a product promotion. To begin, the method may receive an engagement notification from a consumer device. The engagement notification may have data representing an engagement code. Further, the engagement code may be associated with a merchant. The method may then update the engagement data associated with the engagement code. The engagement data may have data that tracks a number of times the engagement code has been scanned by consumer devices. The method may then provide, to the consumer device, product data associated with a product code based on the engagement code being associated with the product code. The product code may have been previously assigned to a manufacturer.
