Abstract: A method for recording a track and an electronic device using the same are provided. When the electronic device loads an operation system, the recording module is automatically enabled and enters a standby state. When a display unit of the electronic device displays an operating interface and the recording module is triggered, the recording module is switched from the standby state to an active state. When the recording module is at the active state, a drawing layer is displayed and covers the operating interface, and an input track is received via the drawing layer. When a storing command is received, the input track is stored to obtain a composite image.

Abstract: An electronic system is provided. The electronic system includes a first electronic device and a second electronic device. The first electronic device includes a first display unit and a first processing unit. The first processing unit is used to run a first operating system. The second electronic device includes a second processing unit. The second processing unit is used to run a second operating system. The first electronic device and the second electronic device independently run the first operating system and the second operating system. When the first electronic device is electrically connected to the second electronic device, a state of the first operating system and the second operating system are respectively maintained and are selectively displayed on the first display unit.
