Abstract

An information processing including a display; a first sensor configured to detect a first object that comes into contact with or approaches the display based on a change in a magnetic field; and a second sensor configured to detect a second object that comes into contact with or approaches the display based on a change in capacitance or resistance.

Claims

1. An information processing device comprising:

a display;

a first sensor configured to detect a first object that comes into contact with or approaches the display based on a change in a magnetic field; and

a second sensor configured to detect a second object that comes into contact with or approaches the display based on a change in capacitance or resistance.

2. The information processing device of claim 1, further comprising:

circuitry configured to determine a first coordinate position of the first object based on an output of the first sensor, and determine a second coordinate position of the second object based on an output of the second sensor.

3. The information processing device of claim 2, wherein

the circuitry is further configured to execute a predetermined function based on the detected first and second coordinate positions.

4. The information processing device of claim 1, further comprising:

circuitry configured to determine that the second object corresponds to a palm of a user'"'"'s hand based on an output of the second sensor, and ignore the detection when the second object is determined to correspond to the palm of the user'"'"'s hand.

5. The information processing device of claim 1, wherein

the second sensor includes a first detecting area and a second detecting area.

6. The information processing device of claim 5, further comprising:

a user interface configured to receive an input indicating a user'"'"'s dominant hand; and

circuitry configured to set an arrangement of the first detecting area and the second detecting area based on the received input.

7. The information processing device of claim 5, wherein

the circuitry is configured to detect a gesture input by a user when an output of the second sensor indicates that the second object is detected in the first detecting area, and execute a predetermined function based on the detected gesture.

8. The information processing device of claim 7, wherein

the circuitry is configured to detect the gesture input when the output of the second sensor indicates that a plurality of the second objects are simultaneously detected in the first detecting area.

9. The information processing device of claim 7, wherein

the circuitry is configured to detect the gesture input when the output of the second sensor indicates that a single second object is detected in the first detecting area and the single second object moves within the first detecting area.

10. The information processing device of claim 5, wherein

the circuitry is configured to determine that the second object detected in the first detecting area corresponds to a palm of a user'"'"'s hand based on an output from the second sensor, and ignore the detection when the second object is determined to correspond to the palm of the user'"'"'s hand.

11. The information processing device of claim 10, wherein

the circuitry is configured to determine that the second object corresponds to the palm of the user'"'"'s hand when the output of the second sensor indicates that a single touch input is detected in the first detecting area.

12. The information processing device of claim 4, wherein

the circuitry is configured to detect a single touch input by a user when an output of the second sensor indicates that the second object is detected in the second detecting area, and execute a predetermined function based on the detected single touch input.

13. The information processing device of claim 4, wherein

the circuitry is configured to determine that the second object detected in the second detecting area corresponds to a palm of a user'"'"'s hand based on an output from the second sensor, and accept the detection when the second object is determined to correspond to the palm of the user'"'"'s hand.

14. A method performed by an information processing device, the method comprising:

detecting, at a first sensor, a first object that comes into contact with or approaches a display of the information processing device based on a change in a magnetic field; and

detecting, at a second sensor, a second object that comes into contact with or approaches the display based on a change in capacitance or resistance.

15. A non-transitory computer-readable medium including computer program instructions, which when executed by an information processing device, cause the information processing device to:

detect, at a first sensor, a first object that comes into contact with or approaches a display of the information processing device based on a change in a magnetic field; and

detect, at a second sensor, a second object that comes into contact with or approaches the display based on a change in capacitance or resistance.
