Abstract

A wearable device includes a wearable element that is worn on the head, a connector that is connected to the wearable element so as to be rotatable around a first rotation axis, and a display that is connected to the connector so as to be rotatable around a second rotation axis. The relationship “ 20 mm≦L1+L2≦ 45 mm” is satisfied provided that a virtual plane includes an eyepiece optical axis of the display and intersects the first rotation axis and the second rotation axis, L1 is the distance from a first intersection that is the intersection of the virtual plane and the first rotation axis to a second intersection that is the intersection of the virtual plane and the second rotation axis, and L2 is the distance from the second intersection to an intersection of an eyepiece and the eyepiece optical axis.

First claim

What is claimed is:

1 . A wearable device comprising:
a wearable element that is worn on a head of a wearer; a connector that is connected to the wearable element so as to be rotatable around a first rotation axis; and a display that is connected to the connector so as to be rotatable around a second rotation axis, and displays a virtual image within part of a field of view of the wearer, wherein a relationship “20 mm≦L 1 +L 2 ≦45 mm” is satisfied provided that a plane that includes an eyepiece optical axis of the display and intersects the first rotation axis and the second rotation axis is referred to as a virtual plane, a distance from a first intersection that is an intersection of the virtual plane and the first rotation axis to a second intersection that is an intersection of the virtual plane and the second rotation axis is referred to as L 1 , and a distance from the second intersection to an intersection of an eyepiece and the eyepiece optical axis is referred to as L 2 .

2 . The wearable device as defined in claim 1 ,
wherein a relationship “L 1 ≧5×L 2 ” is satisfied.

3 . The wearable device as defined in claim 1 ,
wherein a condition “L 2 ≦5 mm” is satisfied.

4 . The wearable device as defined in claim 1 ,
wherein the virtual plane and the first rotation axis are orthogonal to each other, and the virtual plane and the second rotation axis are orthogonal to each other.

5 . The wearable device as defined in claim 1 ,
wherein the virtual plane is parallel to a vertical scan direction of an image that is displayed as the virtual image.

6 . The wearable device as defined in claim 1 ,
wherein the first rotation axis is an axis that passes through an eyeball of the wearer when the wearable element is worn on the head.

7 . The wearable device as defined in claim 1 ,
wherein the first rotation axis is a rotation axis around which the display is rotated to adjust a display position of the virtual image within the field of view, and the second rotation axis is a rotation axis around which the display is rotated to adjust a direction of the eyepiece optical axis.

8 . A wearable device comprising:
a wearable element that is worn on a head of a wearer; a connector that is connected to the wearable element so as to be rotatable around a first rotation axis; and a display that is connected to the connector so as to be rotatable around a second rotation axis, and displays a virtual image within part of a field of view of the wearer, wherein the first rotation axis passes through an eyeball of the wearer when the wearable element is worn on the head, and a relationship “L 1 ≧5×L 2 ” is satisfied provided that a plane that includes an eyepiece optical axis of the display and intersects the first rotation axis and the second rotation axis is referred to as a virtual plane, a distance from a first intersection that is an intersection of the virtual plane and the first rotation axis to a second intersection that is an intersection of the virtual plane and the second rotation axis is referred to as L 1 , and a distance from the second intersection to an intersection of an eyepiece and the eyepiece optical axis is referred to as L 2 .

9 . The wearable device as defined in claim 8 ,
wherein a condition “L 2 ≦5 mm” is satisfied.

10 . The wearable device as defined in claim 8 ,
wherein each of the first rotation axis and the second rotation axis is orthogonal to the virtual plane.

11 . A wearable device comprising:
a wearable element that is worn on a head of a wearer; and a display that displays a virtual image within part of a field of view of the wearer, wherein the display is connected to the wearable element so as to be rotatable around a rotation axis that is orthogonal to a virtual plane that is a plane that includes an eyepiece optical axis of the display, and a condition “L 2 ≦5 mm” is satisfied provided that a distance from an intersection of the rotation axis and the virtual plane to an intersection of an eyepiece and the eyepiece optical axis is referred to as L 2 .

12 . The wearable device as defined in claim 11 ,
wherein the wearable element is an eyeglass-type frame, and the display is provided to a rim of the eyeglass-type frame.
