Abstract

A head mounted display that is attached to an eyeglass frame for use, includes: a first unit and a second unit. The first unit includes a first electrical component including a display element and an eyepiece optical part that allows a user to observe a display image by the display element as a virtual image. The second unit which is a temple tip for display device having a temple connecting part to which a temple of the eyeglass frame is attachable includes a second electrical component and an attachment part in which the first unit is detachably engaged and supported. When the first unit is engaged and supported in the attachment part, the first electrical component and the second electrical component are electrically coupled.

Claims

1. A head mounted display that is attached to an eyeglass frame for use, comprising:

a first unit and a second unit,

wherein

the first unit comprises a first electrical component including a display element and an eyepiece optical part that allows a user to observe a display image by the display element as a virtual image,

the second unit which is a temple tip for display device having a temple connecting part to which a temple of the eyeglass frame is attachable, the second unit including a second electrical component and an attachment part in which the first unit is detachably engaged and supported, and

when the first unit is engaged and supported in the attachment part, the first electrical component and the second electrical component are electrically coupled.

2. The head mounted display according to claim 1, wherein when the first unit is engaged and supported in the attachment part, a load of the first unit is applied to an ear of the user via the second unit.

3. The head mounted display according to claim 1, wherein the attachment part and the first unit each comprise at least a pair of electrodes to electrically couple the first electrical component and the second electrical component when the first unit is engaged and supported in the attachment part.

4. The head mounted display according to claim 1, wherein

in the attachment part, the first unit is engaged and supported to be slidable along the temple tip, and

the attachment part and the first unit each comprises at least a pair of electrodes to electrically couple the first electrical component and the second electrical component when the first unit is engaged and supported in the attachment part.

5. The head mounted display according to claim 4, wherein

the pair of electrodes as the pair at each of the attachment part and the first unit are disposed to be away from each other in a direction orthogonal to a sliding direction of the head mounted display.

6. The head mounted display according to claim 1, wherein the attachment part is disposed above the ear of the user.

7. The head mounted display according to claim 6, wherein the attachment part has a shape that is inclined downwardly toward a front side of the ear of the user.

8. The head mounted display according to claim 1, wherein the second electrical part contains at least one of a power supply, a user information acquisition part, a sound output part and a controller.

9. The head mounted display according to claim 8, wherein

the second electrical part contains a battery, and

when the first unit is engaged and supported in the attachment part, electricity is supplied from the battery to the first electrical component.

10. The head mounted display according to claim 9, wherein the second unit has a center of mass thereof that is located behind the ear of the user.

11. The head mounted display according to claim 9, wherein the battery is disposed behind the ear of the user.

12. The head mounted display according to claim 8, wherein the second electrical component comprises a sensor built therein, and

when the first unit is engaged and supported in the attachment part, output information from the sensor is transmitted to the first electrical component.

13. The head mounted display according to claim 8, wherein the second electrical component comprises a speaker built therein, and

when the first unit is engaged and supported in the attachment part, a sound signal is transmitted from the first electrical component to the second electrical component.

14. The head mounted display according to claim 8, wherein

the second electrical component comprises a sensor, a signal processing circuit, a memory and the power supply comprises a battery built therein, and

when the first unit is not engaged and supported in the attachment part, output information from the sensor is stored in the memory via the signal processing circuit.

15. The head mounted display according to claim 8, wherein

the second electrical component further include a driving circuit of the display element built therein, and

when the first unit is engaged and supported in the attachment part, the display element is driven by the driving circuit.

16. A display device for eyeglasses that is detachably engaged and supported in a temple tip of the eyeglasses for display device having an eyeglass-side electrical component, the display device comprising:

a display-side electrical component including a display element including;

an eyepiece optical part that allows a user to observe a display image by the display element as a virtual image; and

a temple tip connection part that electrically couples the display-side electrical component to the eyeglass-side electrical component when the display device for eyeglasses is engaged and supported in the temple tip for display device.

17. A temple tip for display device, in which a display device for eyeglasses is detachably engaged and supported, the display device for eyeglasses comprising a display-side electrical component comprising a display element, and an eyepiece optical part that allows a user to observe a display image by the display element as a virtual image, the temple tip for display device comprising:

an eyeglass-side electrical component; and
