11/452527

Inventors:

Michael C. Bostock - San Francisco CA, US
Alexander C. Wu - Sunnyvale CA, US

Assignee:

Google Inc. - Mountain View CA

International Classification:

G06F 17/30

US Classification:

707 3, 707 4, 707 10

Abstract:

One embodiment of the present invention provides a system that produces a preference ranking for a set of items based on preferences expressed by users. During operation, the system collects preferences from users between pairs of items in the set of items to be ranked. Next, the system then uses the collected preferences to compute an adjacency matrix for the set of items, wherein each element in the adjacency matrix represents preferences between a corresponding pair of items associated with the element. The system then uses the adjacency matrix to compute the preference ranking for the set of items.

Abstract:

Methods and systems for remote real-time or asynchronous multiplayer gameplay using mobile devices are disclosed. The methods and systems include steps of mounting mobile computing devices in gaming areas associated with users; initiating a game between the users; analyzing movements of the users, ball(s), and/or other game equipment of the game by performing a computer vision algorithm on one or more frames of an input video of the game; and providing feedback to the users, where feedback may include instructions to be performed by the users and player analytics. Embodiments of the present invention use computer vision techniques to enable a resource-limited mobile device such as a smartphone to conduct the aforementioned steps.
