Abstract

A tilt adjusting image including a captured image that is obtained by capturing a wearer wearing a spectacle-type electronic device, and a horizontal line image indicating a horizontal direction identified by a tilt identification part, is displayed. The wearer adjusts a position of the spectacle-type electronic device by a wearer's hand or the like while viewing the tilt adjusting image so that the spectacle-type electronic device becomes horizontal. When the wearer judges that the spectacle-type electronic device has become horizontal, the wearer operates an operation part and inputs a calibration instruction. When the calibration instruction is input, the calibration instruction is transmitted to the spectacle-type electronic device.

First claim

What is claimed is:

1. A calibration method comprising:
a first step identifying a predetermined tilt with respect to a gravity direction based on an acceleration detected by a first acceleration sensor provided in a portable device;
a second step displaying, on a display of the portable device, a tilt adjusting image for adjusting a tilt of a spectacle-type electronic device, based on an image of a wearer of the spectacle-type electronic device captured by the portable device and the predetermined tilt that is identified; and
a third step performing a calibration of a second acceleration sensor provided in the spectacle-type electronic device under a condition that a tilt of the spectacle-type electronic device is adjusted, wherein
the first step identifies a horizontal direction as the predetermined tilt with respect to the gravity direction, and
the second step displays on the display the tilt adjusting image that simultaneously includes the image that is captured, and an image of a horizontal line in the horizontal direction that is identified.

2. A calibration method comprising:
a first step identifying a predetermined tilt with respect to a gravity direction based on an acceleration detected by a first acceleration sensor provided in a portable device;
a second step displaying, on a display of the portable device, a tilt adjusting image for adjusting a tilt of a spectacle-type electronic device, based on an image of a wearer of the spectacle-type electronic device captured by the portable device and the predetermined tilt that is identified; and
a third step performing a calibration of a second acceleration sensor provided in the spectacle-type electronic device under a condition that a tilt of the spectacle-type electronic device is adjusted,
wherein the third step transmits a calibration instruction from the portable device to the spectacle-type electronic device when the portable device receives the calibration instruction while the tilt adjusting image is being displayed, and performs the calibration under a condition that the spectacle-type electronic device receives the calibration instruction.

3. The calibration method as claimed in claim 1 , wherein the third step detects a position of the spectacle-type electronic device by the portable device based on feature points of the spectacle-type electronic device within the image that is captured, transmits a calibration instruction to the spectacle-type electronic device in a case in which the portable device judges that the detected position is in a predetermined relationship with respect to the tilt that is identified, and performs the calibration under a condition that the spectacle-type electronic device receives the calibration instruction.

4. The calibration method as claimed in claim 1 , wherein a fourth step performs the calibration of the second acceleration sensor of the spectacle-type electronic device under a condition that a calibration instruction is input to the spectacle-type electronic device.

5. A portable device comprising:
a capturing device configured to capture an image of a wearer wearing a spectacle-type electronic device;
a first acceleration sensor; and
a processor configured to perform a process including
identifying a predetermined tilt with respect to a gravity direction based on an acceleration detected by the first acceleration sensor;
displaying, on a display, a tilt adjusting image for adjusting a tilt of the spectacle-type electronic device, based on the image that is captured and the predetermined tilt that is identified; and
transmitting, to the spectacle-type electronic device, a calibration instruction that instructs calibration of a second acceleration sensor of the spectacle-type electronic device, under a condition that a tilt of the spectacle-type electronic device is adjusted, wherein

the identifying identifies a horizontal direction as the predetermined tilt with respect to the gravity direction, and
the displaying displays on the display the tilt adjusting image that simultaneously includes the image that is captured, and an image of a horizontal line in the horizontal direction that is identified.

6. A portable device comprising:
a capturing device configured to capture an image of a wearer wearing a spectacle-type electronic device;
a first acceleration sensor, and
a processor configured to perform a process including
identifying a predetermined tilt with respect to a gravity direction based on an acceleration detected by the first acceleration sensor;
displaying, on a display, a tilt adjusting image for adjusting a tilt of the spectacle-type electronic device, based on the image that is captured and the predetermined tilt that is identified; and
transmitting, to the spectacle-type electronic device, a calibration instruction that instructs calibration of a second acceleration sensor of the spectacle-type electronic device, under a condition that a tilt of the spectacle-type electronic device is adjusted,

wherein the transmitting transmits the calibration instruction to the spectacle-type electronic device when the portable device receives the calibration instruction while the tilt adjusting image is being displayed on the display, to perform the calibration under a condition that the spectacle-type electronic device receives the calibration instruction.

7. The portable device as claimed in claim 5 , wherein the processor performs the process further including
detecting a position of the spectacle-type electronic device based on feature points of the spectacle-type electronic device within the image that is captured,
wherein the transmitting transmits the calibration instruction to the spectacle-type electronic device in a case in which the processor judges that the detected position is in a predetermined relationship with respect to the tilt that is identified, to perform the calibration under a condition that the spectacle-type electronic device receives the calibration instruction.

8. A non-transitory computer-readable storage medium having stored therein a program which, when executed by a computer of a portable device, causes the computer to perform a calibration process comprising:
a first procedure identifying a predetermined tilt with respect to a gravity direction based on an acceleration detected by a first acceleration sensor provided in a portable device;
a second procedure displaying, on a display of the portable device, a tilt adjusting image for adjusting a tilt of a spectacle-type electronic device, based on an image of a wearer of the spectacle-type electronic device captured by the portable device and the predetermined tilt that is identified; and
a third procedure performing a calibration of a second acceleration sensor provided in the spectacle-type electronic device under a condition that a tilt of the spectacle-type electronic device is adjusted, wherein
the first procedure identifies a horizontal direction as the predetermined tilt with respect to the gravity direction, and
the second procedure displays on the display the tilt adjusting image that simultaneously includes the image that is captured, and an image of a horizontal line in the horizontal direction that is identified.

9. A non-transitory computer-readable storage medium having stored therein a program which, when executed by a computer of a portable device, causes the computer to perform a calibration process comprising:
a first procedure identifying a predetermined tilt with respect to a gravity direction based on an acceleration detected by a first acceleration sensor provided in a portable device;
