Method for calibrating a binocular displaying device

2:

• The calibrating method according to claim 1, wherein the binocular displaying device is configured to display right and left pictures at a projection distance and the real world target is localized at sensibly the projection distance.

3:

• The calibrating method according to claim 1, further comprises a virtual marker position storing step, during which the position of each of the left and right virtual marker at the alignment condition is stored in a control system embedded in the binocular displaying device.

4:

• The calibrating method according to claim 1, wherein the aligning step is performed manually.

5:

• The calibrating method according to claim 1, wherein each of the right and left virtual markers comprises at least a vertical line.

6:

• The calibrating method according to claim 1, further comprises a user input receiving step, during which a user input indicating when the left and/or the right virtual marker is visually aligned with the real world target at the alignment condition is received.

7:

• The calibrating method according to claim 1, wherein the steps of the method of claim 1 are executed by a processor a plurality of times.

8:

• The calibrating method according to claim 1, wherein the aligning step comprises:
• a first aligning step, during which one of the right and left virtual markers is aligned with the real world target, and
• a second aligning step, during which the other of the right and left virtual markers is aligned with the real world target while maintaining the one of the right and left virtual markers aligned with the real world target.

9:

• The calibrating method according to claim 1, further comprises an interpupillary distance determining step, during which an interpupillary distance is determined.

11:

• A computer program product comprising one or more stored sequences of instructions that are accessible to a processor and which, when executed by the processor, causes the processor to carry out the steps of claim 1.

12:

• A computer readable medium carrying one or more sequences of instructions of the computer program product of claim 11.

13:

• A calibrating system for calibrating the position of pictures on display elements of a binocular displaying device, the binocular displaying device comprising a right display element and a left display element to display right and left pictures, the calibration system comprising:
• virtual markers displaying means configured to display a right virtual marker and a left virtual marker respectively from the right display element and the left display element when the wearer used the binocular displaying device, the right and left virtual markers being at least visually vertically alignable with a real world target at an alignment condition, and
• markers moving means configured to move at least horizontally each of the right and left virtual markers respectively on the right and on the left display elements.

15:

• A binocular displaying system according to claim 14, wherein the calibrating system is embedded in the binocular displaying device.
