Abstract: Augmented reality programs permit graphics to be projected upon a view. A scavenger hunt game can be operated within a retail store utilizing a processing device operating an augmented reality program. The game includes receiving, at a processing device, a list of objects being sought, each object indicating one of a product being sold by the store or a task to be performed within the store. The game further includes, for each object being sought, determining an in-store location for the object, displaying though the augmented reality program in-store navigational instructions for each object being sought based upon the in-store location for the object, and confirming, at the processing device, retrieval of each object being sought.

Abstract: A method for using receipt data to identify medication conflicts is disclosed. The method may begin with linking, by a computer system, a human customer to a first substance. Subsequently, the computer system may initiate a purchase transaction involving the human customer. During the transaction, the computer system may identify a second substance forming part of the purchase transaction. Accordingly, the computer system may find, within a conflicts database, a conflict between the first and second substances. The conflict may correspond to an undesirable effect produced by simultaneous use of the first and second substances. The computer system may then alert the human customer to the conflict.
