OBJECT MAPPING TECHNIQUES FOR MOBILE AUGMENTED REALITY APPLICATIONS

Techniques are disclosed that involve mobile augmented reality (MAR) applications in which users (e.g., players) may experience augmented reality (e.g., altered video or audio based on a real environment). Such augmented reality may include various alterations. For example, particular objects may be altered to appear differently. Such alterations may be based on stored profiles and/or user selections. Further features may also be employed. For example, in embodiments, characters and/or other objects may be sent (or caused to appear) to other users in other locations. Also, a user may leave a character at another location and receive an alert when another user/player encounters this character. Also, characteristics of output audio may be affected based on events of the MAR application.
