INCENTIVIZING USERS TO COLLECT REAL-WORLD ITEMS AND PROVIDE ITEM RATINGS

Systems and methods for incentivizing users to collect real-world items and provide item ratings are described. Theses examples are applicable to a wide variety of different collection scenarios, including the collection of candies by trick-or-treaters during Halloween, the collection of Girl Scout cookies during the local cookie season, toys (e.g., action figures and Legos characters), and the collection of rare items (e.g., out-of-circulation baseball cards, stamps, and coins). These examples allow users to submit data relating to the items they collect (e.g., item types, item quantities, item collection times, and item collection locations). These examples generate a respective inventory of collected items for each user. The inventories are provided to the users for display on their computing devices. On the basis of data derived from the inventories, the examples provide incentives that are structured to encourage user to collect additional items and submit item ratings.
