Abstract

A toilet training device for rewarding the toilet user when excrement enters or is placed in an excrement container by the toilet user. The toilet training device includes an excrement container having an entrance area and a plurality of infrared light-emitting diodes are sequentially triggered and sequentially emit infrared light substantially intersecting the entrance area. The infrared light is detected at the other end of the entrance area by a infrared light detector that generates an electrical signal in response to detected infrared light. A width pulse counter is connected to the detector and generates a first signal in response to a narrow electrical signal and a second signal in response to a wide electrical signal. The first and second signals are responsive to liquid or solid excrement deposition and generate, through control logic, one of a sight or sound signals or both for rewarding the user of the toilet training device.
