A game that dispenses water onto a user is described, as well as methods of play and apparatuses for same. In some embodiments, water is dispensed from headgear after receiving a wireless transmission from a transmitter located on a gun, console or other device.

A system and method of tracking a user input device such as a game controller includes emitting light from multiple light sources in the user input device. The multiple light sources having a known spacing relative to each other on the user input device and at least some of the multiple light sources are capable of emitting light through a inside surface and an outside surface of the user input device. The multiple light sources can define a plane of the user input device that can be used to track the movement, location and orientation of the user input device. The user device is tracked using image data from a camera. The image data is communicated to a computer where the image data is processed to identify the movement, location and orientation of the user input device.

Video games can be improved upon by combining traditional gameplay mechanics (e.g., a player's use of a controller) and live-action combat elements that may be measured and scored. For example, a player may fire projectiles at a target when prompted by a game, may have to dodge projectiles fired at the player as part of the game, may have to traverse the room to touch or move an object, and/or may have to strike a dummy or other object as instructed by the game. Such live-action combat aspects may be incorporated into a video game having otherwise traditional gameplay mechanics.

The present disclosure provides an electrical stimulation apparatus, a control system, and a control method that can reduce inflammation caused by the application of a current to a plurality of electrodes adhered to skin. An electrical stimulation apparatus according to the present disclosure is an electrical stimulation apparatus that provides electrical stimulation to a human body. The electrical stimulation apparatus includes a plurality of electrodes to be adhered to skin of a user and configured to provide electrical stimulation, an output circuit configured to apply a current to the plurality of electrodes, and a control circuit configured to control the current to be applied to the plurality of electrodes by the output circuit. The control circuit is configured to apply a current that is less than or equal to a perception threshold of the user to the plurality of electrodes at a predetermined timing.

A set of game pieces sized and shaped to stack vertically one atop one another to form a stacked arrangement. The set of game pieces including a first game piece configured to place at a bottom position in the stacked arrangement and a second game piece configured to place at a top position in the stacked arrangement wherein each of the game pieces included in the set of game pieces includes a top surface having a game-piece fastening element included thereon, respectively, each of the respective game-piece fastening elements configured to secure to a corresponding headpiece fastening element worn by a user when contact is made between the respective game-piece fastening element and headpiece fastening element during game play. Game play involves a hands-free removal of game pieces from atop the stacked arrangement.
