Claim of US Patent No. 10,993,188

1. An electronic device, comprising:a screen;
a distance sensor, configured to transmit an acknowledgement signal, and receive a feedback signal responding to the acknowledgement signal;
a gravity sensor, configured to detect a gravity acceleration value;
a memory, configured to store at least one program instruction, a threshold value, a variation threshold value, and a predetermined value; and
a processor, electrically connected to the distance sensor, the gravity sensor, and the memory, and loading the at least one program instruction to perform the following steps:
receiving the feedback signal from the distance sensor;
determining a signal strength value of the feedback signal;
comparing the signal strength value with the threshold value obtained from the memory;
comparing the gravity acceleration value obtained from the gravity sensor with the predetermined value obtained from the memory when the signal strength value is greater than the threshold value;
comparing a variation value of the gravity acceleration value with the variation threshold value obtained from the memory when the gravity acceleration value is greater than the predetermined value; and
controlling the screen to operate in a first mode when the variation value is greater than the variation threshold value;
wherein the processor controls the screen to operate in a second mode when the signal strength value is greater than the threshold value but the gravity acceleration value is not greater than the predetermined value, and the second mode is different from the first mode.
