Abstract: An electronic device includes a first housing defining a first hole, a second housing, a camera, and a camera shelter. The second housing includes a receiving part and a fixing part. The camera is fixed to the second housing. The camera shelter includes a body, an operation part, and a connection part. The body and the operation part are received in the receiving part. The connection part engages the fixing part to connect the camera shelter to the second housing. The body is sandwiched between the first housing and the second housing. When the operation part positions in a first position, the first hole defined in the first housing overlaps a second hole defined on the body to expose the camera. When the operation part is moved to a second position, the body of the camera shelter shelters the camera.

Abstract: A system includes a detecting module, a button determining module, and a button enlarging module. The button determining module controls an object detector to detect an object approaches the touch screen and generates a position signal associated with a position on the touch screen where the detected object approaches. The button determining module determines the position on the touch screen where the object approaches according to the position signal and determines one or more buttons designated at the determined position. The button enlarging module enlarges display size of the one or more buttons displayed at the determined position.

Abstract: A wearable electronic device with an automatic rechargeable function includes a rechargeable battery, a base, a cover, a magnet slidably connected to inside of the base, and a converting circuit. The cover is engaged with the base, and includes at least one conducting winding electrically connected to the rechargeable battery. When the wearable electronic device is moved to drive the magnet to slide inside of the base, the magnetic flux density passing through the at least one conducting winding is changed, causing an induction current to be generated. The converting circuit is able to convert the induction current to direct current.
