A wearable vest having an optical sensor is disclosed with a vessel configured to hold a selected liquid. A nozzle is connected to the vessel. The optical sensor is configured to receive an encoded optical signal from one or more of a plurality of optical signal sources. One or more processors coupled to the optical sensor are configured to determine information in the encoded signal, select a response based on the information, and send a signal to enable the selected liquid to be directed out of the vessel through the nozzle towards a wearer of the wearable vest for a selected period of time based on the selected response.

Methods, systems, and devices are described herein for reading at least one dice. In one aspect, a method may include transmitting an RFID signal proximate to at least one dice, for example, which is contained within a dice gaming system. The method may also include receiving at least two RFID responses, with each of the RFID responses associated with different faces of at least one dice. A first RFID response may be associated with a first signal strength and the second RFID response associated with a second signal strength. The method may further include determining which side of the dice is facing upwards based on the first signal strength and the second signal strength using machine learning.

A gaming system may include: an infrared signal emitter configured to emit an infrared signal, the infrared emitter being configured to emit a predetermined number of emissions per a simulated reloading action, the infrared signal being configurable to be associated with one of at least a first team, a second team, and a neutral team, the infrared signal emitter including a handle to be grasped by a player and a trigger to effect emission of the infrared signal; and an infrared signal receiver configured to receive the infrared signal associated with one of the at least the first team, the second team, and the neutral team. Optionally, the gaming system may include a stationary receiver and emitter for integrated use with game players in a further modification of the methods and uses herein. The stationary receiver and emitter may receive and transmit signals, store a memory of activities, teams, players, and other game-playing benefits.

An electronic gaming machine (EGM) includes a display having a display surface configured to provide stereoscopic 3D viewing of at least a portion of the game. The portion of the game includes a 3D interface element. The EGM further includes a locating sensor that generates an electronic signal based on a player's location in a sensing space. The EGM includes an ultrasonic emitter configured to emit an ultrasonic field. At least a portion of the ultrasonic field is located in the sensing space. The EGM also includes one or more processors configured to: identify a location of one or more player features based on the electrical signal from the locating sensor; determine that the location of the player features is associated with the 3D interface element; and control one or more of the ultrasonic emitters based on the identified location to provide tactile feedback to the player.

A compute device can receive a signal associated with a quantity of real-world activity (e.g., exercise) performed by a user. The compute device can define a quantity of virtual activity based, at least in part, on the quantity of real-world activity. The quantity of virtual activity can be different from the quantity of real-world activity. The compute device can send an indication of progress in a virtual world to an output device, for example, such that the user's progress is displayed.
