An interactive, inflatable play system is based on an inflatable structure. A plurality of interaction modules is attached to the inflatable structure. Each interaction module comprises a touch sensor and a light source. An external control module in wireless is in bidirectional communication with the interaction modules. The external control module may comprises a counter and a display and may increment the counter in response to a wireless signal from the interaction modules indicating being touched by a user and displays a counter value.

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.

A prompting device for prompting state information of a physical game character includes a smog machine and a control circuit. The smog machine include a smog chamber, a heating element, and an air-blowing device. The smog chamber has a receiving cavity for receiving smog fluid, an inlet, and an outlet. The inlet and the outlet are in communication with the receiving cavity. The heating element is mounted within the receiving cavity and generates heat to vaporize the smog fluid after an electric current is applied. The air-blowing device is disposed corresponding to the outlet for blowing an air flow towards the receiving cavity. The air flow generated by the air-blowing device enters into the receiving cavity from the inlet and discharges smog within the receiving cavity from outlet. The control circuit is configured to control the smog machine to generate the smog that characterizes the state information.

A game table is illustrates as a combination of the game of table soccer (also called foosball) and air hockey. The game table can be easily converted between a soccer game configuration and an air hockey configuration. In one aspect, the sidewalls of the game table incorporate at least one bushing structure allowing each rod to be selectively disengaged. In certain aspects the game table can be used to play a game using soccer player rods and figures and using a playing piece which floats on an air cushion. In certain embodiments, an asymmetric game playing piece may be used.
