Abstract:
A method for displaying SIM card slot information for use in a device including M SIM card slots, each of which may have a SIM card inserted therein or no SIM card inserted therein. The method includes the following steps. A set of predetermined rules are first determined by the device. Statuses of the M SIM card slots corresponding to the set of predetermined rules are then acquired. Information regarding N of the M SIM card slots are displayed on a display unit of the device according to the set of predetermined rules determined by the current associated network and the acquired statuses of the M SIM card slots, where N =1.
Abstract:
One of the embodiments of the invention provides an input-output calibration method performed by a processing unit connected to an output device and an input device. The output device and the input device correspond to an output device coordinate system and an input device coordinate system, respectively. The processing unit first uses the input device to derive a plurality of lines in the input device coordinate system for M calibration points by sensing a viewer specifying the M calibration points' positions, wherein the plurality of lines are between the M calibration points and the viewer's the predetermined object's different positions, and M is a positive integer equal to or larger than three. Then, the processing unit derives the M calibration points' coordinates in the input device coordinate system according to the plurality of lines and uses the M calibration points' coordinates in the output device coordinate system and coordinates in the input device coordinate system to derive the relationship between the output device coordinate system and the input device coordinate system.
