Abstract

An electronic device includes: a display; a sensor module configured to detect movement of the electronic device; and a control module configured to control such that power is supplied to the display when a movement is detected in the electronic device by the sensor module, to determine whether a user of the electronic device is driving a vehicle based on the detected movement of the electronic device, and to control such that the supply of power to the display is limited when it is determined that the user is driving.

First claim

What is claimed is:

1. An electronic device comprising:
a display;
a communication module configured to receive a steering angle of a steering wheel of a vehicle from an external device;
a sensor module configured to detect movement of the electronic device; and
a control module configured to control such that power is supplied to the display when a movement is detected in the electronic device by the sensor module, to determine whether a user of the electronic device is driving the vehicle based on the detected movement of the electronic device and the steering angle of the steering wheel, and to control such that the supply of power to the display is limited when it is determined that the user is driving,
wherein the control module is further configured to calculate a moving direction of the steering wheel based on the steering angle of the steering wheel and to determine that the user is driving when the moving direction of the steering wheel is identical to a moving direction of the electronic device for a designated number of times or more.

2. The electronic device of claim 1 , wherein the control module is further configured to determine an angle formed by the movement of the electronic device and to determine that the user is driving when the angle formed by the movement of the electronic device is identical to the steering angle for a designated number of times or more.

3. The electronic device of claim 1 , further comprising:
a memory configured to store a length from a center of a steering wheel of the vehicle to the electronic device while the user grips the steering wheel,
wherein the control module is further configured to determine a radius formed by the movement of the electronic device and to determine that the user is driving when the radius is identical to the length stored in the memory for a designated number of times or more.

4. The electronic device of claim 1 , wherein the control module is further configured to learn the determination result of whether the user is driving and to determine whether the user is driving based on the learned result when the steering angle is not received from the external electronic device.

5. The electronic device of claim 1 , further comprising:
a communication module configured to receive a beacon signal from an external electronic device,
wherein the control module is further configured to determine that the user is driving when the beacon signal is received from the external electronic device.

6. A display control method of an electronic device, the method comprising:
detecting, by a sensor module of the electronic device, movement of the electronic device;
receiving, by a communication module, a steering angle of a steering wheel of a vehicle from an external device;
supplying, by a control module of the electronic device, power to a display of the electronic device when a movement is detected in the electronic device;
calculating, by the control module, a moving direction of the steering wheel based on the steering angle of the steering wheel;
determining, by the control module, whether a user of the electronic device is driving the vehicle based on the detected movement of the electronic device and the steering angle of the steering wheel;
determining, by the control module, that the user is driving when the moving direction of the steering wheel is identical to a moving direction of the electronic device for a designated number of times or more; and
limiting, by the control module, the supply of power to the display when it is determined that the user is driving.

7. The display control method of claim 6 , wherein the determining of whether the user device is driving comprises:
determining, by the control module, an angle formed by the movement of the electronic device; and
determining, by the control module, that the user is driving when the angle formed by the movement of the electronic device is identical to the steering angle.

8. The display control method of claim 6 , wherein the determining of whether the user is driving comprises:
determining, by the control module, a radius formed by the movement of the electronic device; and
determining, by the control module, that the user is driving when the radius is identical to a length from a center of the steering wheel to the electronic device while the user grips the steering wheel for a the designated number of times or more, the length being previously stored in the memory.

9. The display control method of claim 6 , further comprising:
learning, by the control module, the determination result of whether the user is driving; and
determining, by the control module, whether the user is driving based on the learned result when the steering angle is not received from the external electronic device.

10. The display control method of claim 6 , further comprising:
receiving, by the control module, a beacon signal from an external electronic device; and
determining, by the control module, whether the user is driving when the beacon signal is received from the external electronic device.

11. A non-transitory computer readable medium containing program instructions for performing a display control method of an electronic device, the non-transitory computer readable medium comprising:
program instructions that supply power to a display of the electronic device when a movement is detected in the electronic device;
program instructions that calculate a moving direction of a steering wheel of a vehicle based on a steering angle of the steering wheel received by a communication module from an external device;
program instructions that determine whether a user of the electronic device is driving the vehicle based on the detected movement of the electronic device and the steering angle of the steering wheel;
program instructions that determine that the user is driving when the moving direction of the steering wheel is identical to a moving direction of the electronic device for a designated number of times or more; and
program instructions that limit the supply of power to the display when it is determined that the user is driving.
