Operation input device, operation input method, and program
First Claim
1. An operation input device comprising:
- a touch pad that outputs a detection signal indicating a coordinate corresponding to a contact state where a finger is in contact with the touch pad;
a first interface which, based on the detection signal, detects a contact region in which the finger is in contact with the touch pad; and
a second interface which detects a proximity region in which the finger is in proximity to, without contacting, the touch pad;
whereinthe proximity region is used to determine whether or not to use a pointed coordinate that is pointed by the finger on the touch pad based on whether or not an area of the contact region detected by the first interface is greater than or equal to a threshold value;
the pointed coordinate is determined based on the contact region detected and the proximity region in a case that the area of the contact region detected is greater than or equal to the threshold value; and
the pointed coordinate is determined based on only the contact region detected in a case that the area of the contact region detected is not greater than or equal to the threshold value.

Abstract
A touch pad outputs a detection signal indicating a coordinate corresponding to a contact state where a finger is in contact with the coordinate detecting unit, and a detection signal indicating a coordinate corresponding to a proximity state where the finger is in proximity to, without contact with, the coordinate detecting unit. An operation input device detects, based on the detection signals, a contact region in which the finger is in contact with the coordinate detecting unit, and a proximity region in which the finger is in proximity to, without contact with, the coordinate detecting unit. Then, the operation input device determines a pointed coordinate based on the contact region detected and the proximity region detected.

6. An operation input method comprising:
-
detecting a contact region in which a finger is in contact with a touch pad based on a detection signal output from the touch pad; detecting a proximity region in which the finger is in proximity to, without contacting, the touch pad; determining whether or not to use the proximity region to determine a pointed coordinate that is pointed by the finger on the touch pad based on whether or not an area of the contact region detected is greater than or equal to a threshold value; determining the pointed coordinate based on the contact region detected and the proximity region detected in a case that the area of the contact region detected is greater than or equal to the threshold value; and determining the pointed coordinate based on only the contact region detected in a case that the area of the contact region detected is not greater than or equal to the threshold value;
whereinthe detection signal indicates a coordinate corresponding to a contact state where the finger is in contact with the touch pad.

7. A non-transitory computer readable medium including a computer program which causes a computer to execute a method comprising:
-
detecting a contact region in which a finger is in contact with a touch pad based on a detection signal output from the touch pad; detecting a proximity region in which the finger is in proximity to, without contacting, the touch pad; determining whether or not to use the proximity region to determine a pointed coordinate that is pointed by the finger on the touch pad, the determination being performed based on whether or not an area of the contact region detected is greater than or equal to a threshold value; determining the pointed coordinate based on the contact region detected and the proximity region detected in a case that the area of the contact region detected is greater than or equal to the threshold value; and determining the pointed coordinate based on only the contact region detected in a case that the area of the contact region detected is not greater than or equal to the threshold value;
whereinthe detection signal indicates a coordinate corresponding to a contact state where the finger is in contact with the touch pad, and a second detection signal indicating a coordinate corresponding to a proximity state where the finger is in proximity to, without contacting, the touch pad.
