Description

Headset

The present invention relates to a head-mounted device, and particularly relates to a head-mounted device used in augmented reality.

Augmented reality is a technology that augments virtual information into real space. It uses a camera to obtain real-time scenes in real space, and superimposes the virtual images to be augmented into real-time scenes in real space through computer operations. In order to combine and interact with virtual images and real-time scenes in real space.

At present, headsets used in augmented reality (hereinafter referred to as augmented reality headsets) have been proposed. Most of the augmented reality headsets use mobile phones to provide virtual images to be augmented. Among them, the augmented reality headset device There is a half lens, and the display screen of the mobile phone corresponds to the half lens setting. Therefore, users wearing augmented reality headsets can view real-time scenes in real space through the semi-lens, and the virtual image displayed by the mobile phone can be reflected to the user's eyes through the semi-lens, so as to superimpose the virtual image The effect of the real-time scene to the real space. The installation space of a common augmented reality headset for accommodating mobile phones is close to the semi-lens. When the user wears the augmented reality headset, the overall weight of the augmented reality headset is concentrated on the user’s face, and Cause users to feel uncomfortable wearing.

The invention provides a head-mounted device, which can improve the wearing comfort of a user.

The head-mounted device of the present invention is suitable for a user to wear on the head. The head-mounted device includes a main body, two half lenses, two displays, a docking station and an image capturing element. The main body has a light-transmitting part and a mounting part connected to the light-transmitting part, wherein the mounting part has a first section close to the light-transmitting part and a second section far away from the light-transmitting part. The two half lenses are arranged on the light-transmitting part of the main body. The two displays are arranged in the main body, wherein the two displays are located in the first section of the mounting portion, and are respectively opposed to the two half lenses. The docking station is detachably disposed in the second section of the installation part, and the docking station has an installation space for accommodating the portable device. The image capturing element is arranged in the docking station and is electrically connected to the two displays. When the user wears the head-mounted device on the head, the docking base falls directly above the user's head.

Based on the above, the head-mounted device of the present invention arranges the installation space for accommodating the portable device (such as a mobile phone) away from the half-lens, so as to avoid excessive concentration of the overall weight of the head-mounted device on one side after the portable device is loaded. Therefore, when the user wears the head-mounted device, the overall weight of the head-mounted device can be distributed to the head and face, thereby improving the wearing comfort of the user.

In order to make the above-mentioned features and advantages of the present invention more comprehensible, the following specific embodiments are described in detail in conjunction with the accompanying drawings.

FIG. 1 is a schematic diagram of a head-mounted device worn on the head of a user according to an embodiment of the present invention.

More specifically, the docking station 120 is disposed at a section of the installation portion 112 away from the light-transmitting portion 111, and the docking station 120 has an installation space 121 for accommodating the portable device 30.

Since the mounting space 121 of the docking station 120 for accommodating the portable device 30 is set away from the light-transmitting portion 111, after the portable device 30 is loaded on the head-mounted device 100, the overall weight of the head-mounted device 100 will not be excessively concentrated on the single unit. side. Therefore, when the user wears the head-mounted device 100, the overall weight of the head-mounted device 100 can be distributed to the head 20 and the face 21, thereby improving the wearing comfort of the user. For example, when the user wears the head-mounted device 100, the docking station 120 will fall directly above the head 20 of the user.

Fig. 3 is a schematic front view of a head-mounted device according to an embodiment of the present invention. Fig. 4 is a schematic top view of a head-mounted device according to an embodiment of the present invention. 2 to 4, the mounting portion 112 has a first section 112a close to the light-transmitting portion 111 and a second section 112b far from the light-transmitting portion 111, wherein the docking station 120 is disposed in the second section 112b, and An image capturing element 130 is provided in the docking station 120. The portable device 30 may be a mobile phone, and the image capturing element 130 may be a wide-angle lens, such as a 180-degree wide-angle lens. The image capturing element 130 is positioned on the portable device 30 to obtain a virtual image displayed by the portable device 30. It should be noted that the type of the portable device 30 and the type of the image capturing element 130 are not limited to the above, and can be adjusted according to design requirements.

In this embodiment, the head mounted device 100 further includes two semi-lenses 140 and two displays 150 and 151, wherein the two semi-lenses 140 are symmetrically disposed on the light-transmitting part 111 of the main body 110, and the two displays 150 and 151 are disposed on the main body. 110 and located in the first section 112a of the mounting portion 112. The two half lenses 140 and the two displays 150 and 151 are arranged one to one, and the image capturing element 130 and the two displays 150 and 151 are connected electrically or wirelessly. Therefore, the virtual image obtained by the image capturing element 130 can be transmitted to the two displays 150 and 151.

Furthermore, each half lens 140 is located on the corresponding display 150, 151, in order to ensure that the virtual image displayed by each display 150, 151 can be reflected to the user’s eye through the corresponding half lens 140, each display 150, The orthographic projection of 151 on the light-transmitting part 111 overlaps with the corresponding half lens 140. Accordingly, the user wearing the head-mounted device 100 can view the real-time scene in real space through the two half lenses 140, and the head-mounted device 100 can use the image capturing element 130 to cooperate with the two displays 150, 151.
