ELECTRONIC DEVICE AND METHOD FOR CONTROLLING DISPLAYED INTERFACE ACCORDING TO POSTURE OF INPUT DEVICE

摘要

An electronic device and display control method includes a plurality of first receivers and second receivers, respectively to receive first electromagnetic waves and second electromagnetic waves. An input device transmits first and second electromagnetic waves respectively from transmitters at opposite ends of the input device. Programs cause at least one processor to determine an actual first distance and an actual second distance according to the different electromagnetic waves and determine whether the input device is in a certain orientation in relation to the electronic device. The method lights up a backlight device and displays an unlocked interface on a display device if the input device is in the certain orientation.

1. An electronic device comprising:
an input device comprising:
a first emitter which emits a plurality of first electromagnetic waves;a second emitter which emits a plurality of second electromagnetic waves; a computing device comprising:
a plurality of first receivers configured to receive the plurality of first electromagnetic waves;a plurality of second receivers configured to receive the plurality of second electromagnetic waves;at least one processor;a non-transitory storage device coupled to the at least one processor and storing one or more programs, which when executed by the at least one processor, cause the at least one processor to:determine an actual first distance according to the first electromagnetic waves received by the first receivers, determine an actual second distance according to the second electromagnetic waves received by the second receivers;determine whether the input device is oriented in an operation posture according to the actual first distance and the actual second distance; andlight up a backlight device and display an unlocked interface on a display device if the input device is in the operation posture.
