Abstract: Platform mechanics including the generation and consumption of energy-based virtual currency are described. A method of generating energy-based virtual currency includes receiving a signal generated by a sensor carried by a user. The method also includes analyzing the signal to validate that an activity was performed by the user in the real world or that a state associated with the user occurred in the real world. The method also includes awarding energy-based virtual currency to the user in response to validating that the activity was performed by the user or that the state associated with the user occurred in the real world. A method of redeeming energy-based virtual currency includes receiving energy-based virtual currency that can be redeemed for value in a virtual world or in the real world. The method also includes redeeming at least some of the energy-based virtual currency for value in the real world.

Abstract: A user-interface system adapted to navigate through a plurality of menus is disclosed. The system comprises a display system comprising a display having a category area on a first portion of the display, the category area displaying a plurality of categories, including a currently displayed category. Each of the plurality of categories has a plurality of items. The display also has a marquee area on a second portion of the display, which displays items of the currently displayed category. The system further comprises a scrolling mechanism for scrolling through items of each category of the plurality of categories. The marquee area is updated by the scrolling mechanism to display the corresponding items in each category. The scrolling mechanism also indicates a position of a currently displayed item of a currently displayed category by updating the category area. Various embodiments are disclosed.
