    Abstract: There is provided an input device including at least one input unit, a trigger detection unit, a storage unit and an analysis and processing unit. The at least one input unit is for inputting a plurality of trigger events by a user. The trigger detection unit is configured to detect the trigger events of the at least one input unit and generate a trigger signal corresponding to each of the trigger events. The storage unit is configured to record an operating condition associated with the user. The analysis and processing unit is configured to analyze an operating pattern of the trigger signals and determine a warning time according to the operating condition and the operating pattern.

    Abstract: A game board device is provided for carrying and identifying game pieces that are divided into different piece types. The game board device includes a board, a plurality of optically identifying modules, and a processing module electrically coupled to the optically identifying modules. The optically identifying modules respectively correspond in position to detection regions of the board. Each of the optically identifying modules includes a light emitter that can emit light toward the corresponding detection region and a light receiver that can receive light reflected by the corresponding detection region. When any one of the detection regions is in an unoccupied mode, the corresponding optically identifying module can emit an unoccupied signal. When any one of the detection regions is in an occupied mode, the corresponding optically identifying module enables an identification signal that corresponds to the piece type of the corresponding game piece to be emitted therefrom.

    Abstract: A detection device and an indoor navigation system are provided. The detection device includes two detection modules each including a sound receiver for receiving sound from a peripheral object and a signal converting circuit that is electrically coupled to the sound receiver and that is configured to convert input signal from the sound receiver into a target spectrogram. The two spectrograms from the signal converting circuits have a time/phase difference, and at least one wireless earphone includes a storage unit and a judging circuit that is electrically coupled to the storage unit and the two signal converting circuits. The judging circuit is configured to compare any target spectrogram with basic spectrograms of the storage unit so as to determine which kind of objects the peripheral object is, and is configured to obtain an instant position of the peripheral object by the time/phase difference.
