Abstract

A method changes the state of an electronic device to a second state from a first state, where the electronic device includes an input portion for interaction with an object. The method includes the steps of: monitoring at least one sensor having a detection range at least partially disposed near the input portion, determining whether the object is within the detection range of the sensor, determining movement characteristics of the object when the object is detected, determining if the movement characteristics of the object put the object on a path to contact the input device, and changing the state of the electronic device from the first state to the second state when the object is on a path to contact the input device.

Claims

1. A method of changing the state of an electronic device to a second state from a first state, the electronic device including an input portion, the method comprising the steps of:

monitoring at least one sensor having a detection range at least partially disposed near the input portion;

determining whether an object is within the detection range of the sensor;

determining movement characteristics of the object when the object is detected;

determining if the movement characteristics of the object put the object on a path to contact the input device; and

changing the state of the electronic device from the first state to the second state when the object is on a path to contact the input device before the object contacts the electronic device.

2. The method of claim 1, wherein the electronic device is an infotainment system in a vehicle.

3. The method claim 1, wherein the at least one sensor is a plurality of optical sensors.

4. The method of claim 1, wherein the at least one sensor is one of an at least one capacitive field sensor, an ultrasonic sensor, a radar sensor, and a thermal sensor.

5. The method of claim 1, wherein the movement characteristics include a path of the object.

7. The method of claim 1, wherein the movement characteristics include an acceleration of the object.

8. The method of claim 1, wherein changing the state of the electronic device from a first state to a second state includes adding content to a display in electronic communication with the electronic device.

9. A method of determining when an object is going to interact with an infotainment system in a vehicle, the method comprising the steps of:

providing the infotainment system in a standby state, the infotainment system having a display and an input portion;

providing at least one sensor capable of determining an acceleration of the object when it is in proximity to the infotainment system;

monitoring the at least one sensor for the object;

analyzing data from the at least one sensor to determine an acceleration and an estimated path of the object;

determining whether the acceleration and the estimated path of the object indicate that the object will contact the input portion of the infotainment system; and

putting the infotainment system in a ready state when it is determined that the user will contact the input portion of the infotainment system before the object contacts the input portion.

10. The method of claim 9, wherein the at least one sensor is a capacitive field sensor.

11. The method of claim 9, wherein the at least one sensor is a pair of optical sensors.

12. An electronic device that is capable of a first state and a second state, the electronic device comprising:

an input portion;

a display portion;

at least one sensor having a detection range at least partially disposed near the input portion for detecting an object;

a first control logic that determines movement characteristics of the object;

a second control logic that determines whether the movement characteristics put the object on a path to contact the input portion; and

a third control logic to put the electronic device in the second state if the object is on a path to contact the input portion before the object contacts the input portion.

13. The electronic device of claim 12, wherein the input portion and the display portion are combined into a touch screen.

14. The electronic device of claim 12, wherein the electronic device is an infotainment system in a vehicle.

15. The electronic device of claim 12, wherein the at least one sensor is one of an ultrasonic sensor, a plurality of optical sensors, a radar sensor, and a thermal sensor.

16. The electronic device of claim 12, wherein the at least one sensor is at least one capacitive field sensor.

17. The electronic device of claim 12, wherein the movement characteristics include an estimated path of the object.

18. The electronic device of claim 12, wherein the movement characteristics include an acceleration of the object.

19. The electronic device of claim 12, wherein the first state has the display in one of a low-brightness condition, a de-contented condition, and an off condition, and wherein the second state has the display in one of a viewing condition and a full-contented condition.

20. The electronic device of claim 12, wherein the first state has the display in a de-contented condition and the second state has the display in a full-contented condition.
