Abstract: An interactive system includes an input device and a base device that, when receiving an input from the input device, outputs an interactive effect. In some embodiments, the input device may include a pressure indicator, such as an aperture or a visual pattern. The base device may include a sensor, such as an air pressure sensor, a camera or image sensor, or a pressure sensor. When the input device is position on the base device and pressure is applied to a body of the input device, the sensor may detect the pressure and/or measure an amount of the pressure, and send an indication to a controller of the base device. The controller may cause an output device to output the interactive effect based on the pressure and/or the amount of the pressure.
