Abstract: A touch control detecting method applied to an electronic apparatus comprising an image sensor. The touch control detecting method comprises: (a) capturing a plurality of sensing images via the image sensor; and (b) determining if an object performs a predetermined touch control operation to the electronic apparatus, according to a brightness variation tendency of the sensing images. The predetermined touch control operation is a long press operation.

Abstract: A navigation device applied to a wireless identification tag includes a movable signal transceiver and an operation processor. The movable signal transceiver is adapted to transmit a detection signal and receive an actuation signal relevant to the detection signal. The operation processor is electrically connected to the movable signal transceiver. The operation processor is adapted to analyze the actuation signal to acquire relative position between the movable signal transceiver and the wireless identification tag, and generate a motion parameter in accordance with the relative position for moving the movable signal transceiver.

Abstract: A wearable device and a portable apparatus are provided. The wearable device includes two wireless earphones each including a speaker, a sound receiver for receiving sound from a peripheral object, and a signal converting circuit that is electrically coupled to the sound receiver and 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, the two signal converting circuits, and the two speakers. 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.
