Abstract: An interactive education system includes a storage, an output device, a processor, an input device and a recognition device. The processor controls the output device to produce voice based on a hint on a target answer stored in the storage. The recognition device generates a response through performing speech recognition on input data generated by the input device from voice of a user. The processor controls the output device to produce voice based on whether the response matches the target answer or any relevant characteristic. Depending on a count of consecutive occurrences of a failed event, the processor controls the output device to produce voice based on another hint or the target answer.

Abstract: A docking station is used for cooperating with a computer host, and the computer host has a first power connecting portion and a first peripheral component connecting portion.
