Description

Augmented reality glasses device

Technical field

The invention relates to an augmented reality glasses device.

Background technique

Augmented reality technology is a new technology that integrates real world information and virtual world information "seamlessly". It is physical information that is difficult to experience in a certain time and space in the real world. After superimposing, the virtual information is applied to the real world and perceived by human senses, so as to achieve a sensory experience beyond reality. Real environment and virtual objects are superimposed on the same picture or space in real time.

technical problem

In recent years, wearable image display devices such as head-mounted displays have attracted attention. As such a head-mounted display, a transparent head-mounted display capable of simultaneously viewing an image (virtual image) from a display element and an external image (external light) is known. Such as Google Glass, Microsoft's HoloLens, etc., their solutions are based on the principle of the projector, the results achieved are not satisfactory.

Technical solutions

In view of such a situation, the present invention provides a glasses device with a simple structure and better effect for implementing augmented reality.

At present, transparent display technology has been developed, such as new OLED displays or graphene screens. They can not only emit image light, but also allow external light to pass through, with high light transmittance and good display brightness. It is believed that it will be popularized in the near future. .

The technical solution adopted by the present invention is: one of the lens elements of the augmented reality glasses device is a first optical element in order from the outside to the eye, which changes the position of the external light in the depth direction from the A position to the B position; A transparent display element that emits image light containing image information and allows external light to pass through; a second optical element that restores the position of the external light in the depth direction from the B position to the A position, and enables the light emitted by the transparent display element The position of the image light in the depth direction is projected into the human eye at a suitable position for the human eye.

It can be seen that the role of the second optical element is to make the image light emitted by the transparent display screen project into the human eye at a position suitable for the depth direction of the eye, and in the process, the position of the external light projected in the depth direction of the human eye is also changed. The function of the first optical element is to correct the position in the depth direction of the external light, so that the external light is finally projected into the human eye at the position in the depth direction observed by the naked eye or after vision correction.

While the user can observe the real world approximately with the naked eye, the virtual image emitted by the transparent display screen is superimposed on the real world observed by the user in real time, allowing the user to experience the charm of augmented reality technology.

In order to improve the user experience, the device according to the present invention may further have the following additional technical features:

Preferably, the first optical element and the second optical element may be a combination of a concave lens and a convex lens, or a combination of a Fresnel lens, and other optical elements having excellent performance.

Preferably, the transparent display element may be an OLED display or a graphene screen, and other transparent display elements having excellent performance.

Preferably, the lens element is fixed by a lens frame and prevents water, dust and the like from entering the lens element.

Preferably, when the user has nearsightedness or farsightedness, the second optical element can be replaced with a third optical element, or a third optical element is added to the side of the second optical element near the glasses, which makes the external light go deeper. The position of B is changed from the B position to a position suitable for the human eye in the depth direction and projected into the eye.

Preferably, when the user needs, the distance between the first optical element and the transparent display element, or the second optical element and the transparent display element can be adjusted manually or automatically, which enables the position of the external light and the image light in the depth direction. Finally, it is projected into the eye at a suitable position for the human eye.

Preferably, the first optical element may be replaced with a light-shielding layer, or a light-shielding layer may be provided outside the first optical element to block external light from entering, so that the device is changed to a virtual reality glasses device.

Preferably, a filter layer may be provided on the surface of the transparent display screen or the first optical element of the augmented reality glasses, which allows external light to pass through and filters out the image light emitted by the display screen to improve the user experience.

Preferably, a camera, a gyroscope, a magnetic sensor, a headset, a microphone, an acceleration sensor, etc. may be added to the augmented reality glasses device to improve the user experience.

Preferably, a wireless communication unit WIFI, Bluetooth, etc. can be added to the augmented reality glasses device, which can be connected to smart devices such as mobile phones and computers to improve user experience.

It should be noted that the position in the depth direction in the text refers to the self-considered position of the image obtained by observation by the human eye and the distance of the human eye. As an example, when a user views an image emitted by the transparent display through the device, the display itself is about 5 cm away from the human eye. That is, if there is no second optical element, the position of the image emitted by the display in the depth direction is It is 5 cm, but through the action of the second optical element, the image emitted by the display screen is projected into the human eye at a distance of more than 1 meter, that is, the position where the second optical element transmits the image emitted by the transparent display screen in the depth direction. Changed from 5 cm to more than 1 meter.

Beneficial effect

The beneficial effects of the present invention are simple structure, providing an augmented reality glasses device different from the current one, reducing cost and improving user experience.
