Description

Transparent near-eye display device

The present invention relates to a near-eye display device, and more particularly to a transparent near-eye display device that is separable from a frame and is provided with a collapsible transmissive display and has a function of continuously providing a magnetic north orientation.

A near-eye display device or a near-to-eye display device is a novel wearable device that is constructed with a display directly in front of the user's field of view, on which various displays can be displayed. Digital content provided by external devices, including images, photos, web pages, e-mails and digital maps, external devices such as smart phones, tablets or notebooks, and displays for imaging on near-eye display devices can be transparent Or opaque, according to the type of display, the near-eye display device is generally divided into two types, one is a transparent near-eye display device, and the other is of course an opaque near-eye display device.

In the case of an opaque near-eye display device, the user displays digital content using a conventional opaque display, and the opaque near-eye display device uses an appropriate size conventional LCD panel as an opaque display, which is opaque compared to a transparent near-eye display device.

However, although the transparent near-eye display device appears to be convenient and has a sense of avant-garde technology, it still has many defects and disadvantages that may cause various inconveniences to the user, and needs to be overcome. For example, the transparent near-eye display device is completely fixed to the frame of the frame-like frame, even if the frame is The type is not suitable for this user, but the user has no choice of the type of the frame, or in some cases, although the transparent near-eye display device uses a transparent transparent display, the user can still see the surrounding environment. However, the digital content appearing on the display is still more or less blocked or obscured to the user's field of view, because after all, the display is still placed directly in front of the user's eyes, especially when the user is moving, running or walking. Even if only part of the field of view is obscured, it is likely to lead to safety concerns. In addition, if the user is moving, the user will continue to have direction guidance or path navigation requirements, especially on the display. Sustainability of this service.

For the sake of his position, the applicant has conceived the "transparent near-eye display device" of this case, based on the shortcomings of the conventional technology, through careful experimentation and research, and the spirit of perseverance, which can overcome the shortcomings of the above-mentioned conventional technologies. The following is a brief description of the creation.

In view of various shortcomings of the conventional transparent near-eye display device, the present invention provides a novel transparent near-eye display device which can be separated from the frame of the frame-like frame and is provided with a collapsible transmissive display and has The function of the magnetic north direction can be continuously tracked.

However, although the transmissive display unit 30 is a transparent screen, the digital content displayed on the transparent screen inevitably obscures or blocks a portion of the user's field of view because, under normal use conditions, the transmissive display Unit 30 will appear directly in front of the user's eyes, so when the device is in use, especially when the user is moving or walking, it will cause safety problems.

Please refer to the 3(a) to 3(b) diagrams together. The 3(a) diagram shows the stereoscopic view of the present near-eye display device in use. The penetrating display is used in this state. It has been picked up to the top of the frame, and Figure 3(b) shows a stereoscopic view of the present near-eye display device in use. In this state of use, the transmissive display has been rotated to the side of the frame to the side of the frame. Everywhere.

The rotatable connection unit 40 (ie, the squat connection unit) is used to rotatably/decoupleably connect both the transmissive display unit 30 and the housing 10. For example, the rotatable connection unit 40 is preferably a The hinged or pivoted connection element, through the rotatable or snagging connection of the rotatable connection unit 40, the transmissive display unit 30 can be swung or rotated to remove from the user's field of view/ Removal, for example, the transmissive display unit 30 can be lifted over the frame, as shown in Figure 3(a), or rotated to the side of the frame, as shown in Figure 3(b), and the user can return To the original full view.

The present near-eye display device introduces a rotatable connection unit for rotatably/depressibly connecting both the transmissive display unit 30 and the housing 10, and the transmissive display unit 30 is preferably permeable, for example, to have a waterproof effect. The flexible plastic cable or the flexible circuit substrate is electrically connected to the microprocessor module disposed in the housing 10.

Therefore, due to the arrangement of the rotatable connection unit 40, the transmissive display unit 30 can be moved into the field of view whenever necessary by the user to observe the virtual digital content displayed on the transmissive display unit 30, when not required At this time, the transmissive display unit 30 can be moved out of the field of view to regain a bright and unobstructed view state.

In addition, the present near-eye display device can also perform a magnetic north search program by actively launching an application (App) built in the microprocessor module to continuously guide the user on the transmissive display. Indicating the magnetic north direction, the App indicates the magnetic north direction by working with the compass, gyroscope and acceleration gauge in the motion sensor.

After connecting to the smart phone via the connector, the first magnetic north search and correction scheme in the app will be automatically activated on the device. The user first removes the electromagnetic interference that occurs near the eye display device according to the guidelines in the calibration procedure in the App. Then the user can put the smart phone in the pocket of his body, or hang the smart phone on his chest, or put the phone in the pocket of the armband, then the operation screen will be directly projected and continuously displayed. Penetrating display.

The miniature air mouse fixed on the fingertip or wrist can be used to replace the touch control used in mobile phones, and to command and operate the smart phone, the air mouse through the wireless communication module, for example: Bluetooth communication The agreement, electrically connected to the smart phone, allows the user to control and direct the entire application of the App by using the air mouse. In the entire magnetic north search and correction process, the user's hands are always in a free operation. The state of the final App will use the compass to automatically and continuously guide and indicate the magnetic north direction.

After completing the search and calibration process, the App will close the compass and then start using the gyroscope to detect and calculate the difference between the user's front-front direction and the magnetic north direction. Immediately afterwards, the calculated difference is graphically displayed on the transmissive display. For example, the arrow symbol can be used, so no matter how the user moves or moves in any direction, regardless of rotation or in-situ looping, etc. The magnetic north direction will always be continuously guided and indicated on the penetrating display, and let the user know that the user can not only know the current moving direction, but also know which main azimuth segment the current moving direction belongs to. For example: the Eastern section, the southern section, the western section, the northern section, the northeast section, the southeast section, the northwest section or the southwest section, etc., the App can even adjust or rotate according to this. The digital map or 3D image displayed on the transmissive display automatically aligns with the current direction of movement of the user, because the compass has been closed, so even if the user passes or passes through an area with multiple electromagnetic interference, the orientation and indication of the magnetic north direction Will not be affected or interfered, can maintain normal and accurate operation, users will not be misled Moving towards the wrong direction.

Next, the second magnetic north search and correction scheme in the App will be described here. When the electromagnetic interference occurs around the eye display device, the earth magnetic field cannot be accurately measured or detected, and the second scheme can be considered.

The App actively initiates the launch of the micro-camera to capture at least one near field from the surroundings of the device's current location, and attempts to find or extract multiple landscape features from the acquired images, such as landmarks, Features such as local scenery, streetscapes, characteristic structures, environmental features, signs on the road signs, or text, and then the App accesses the cloud network database and maps the extracted landscape features to the landscape information stored in the database. The comparison can be used to identify the location of the device where it is currently located, and then the App can further point or correct the magnetic north direction. During the execution of the second scheme, especially during the shooting of the surrounding environment, the App may Proactively instruct the user to rotate the head to collect as much capital as possible from the captured image In this solution, the computing operation is quite heavy, so the App will command device access such as grid computing, etc., using the powerful computing functions of the cloud network, that is, to perform landscape feature recognition and comparison.

Next, the third magnetic north search and correction scheme in the App will be described here. As long as an external device, such as a smart phone, can normally detect and receive the GPS signal, the third solution can be considered; the App actively initiates the call. The GPS receiving module and the motion sensing module on the near-eye display device, then the App may guide the user to move a certain distance linearly in any direction, for example: 30 meters, when the App detects that the user moves more than 30 At the time of the rule, the App will send a signal, such as a sound or vibration, to inform the user to return to the original starting point, according to which the App can calculate and recognize the magnetic north direction according to the received GPS signal and the gyroscope.

In summary, the first solution can be implemented at any location, including in underground structures or facilities. As long as there is no excessive electromagnetic interference around the near-eye display device, the second solution is better suited for wireless communication. The location, because the second program has a large number of data and computing tasks that need to be transmitted and executed, so it is very necessary to support from the cloud database or grid computing. The third solution is better suited for implementation in outdoor venues, or as long as it can be used in external devices. The location where the GPS signal is connected can be used. Although the magnetic north direction can be found accurately based on the GPS signal, the implementation site needs to be a relatively open field, because there is enough space for the user to The direction moves a certain distance long enough.

In actual use, depending on the local status of the field in which the device is located, the user can switch the execution autonomously or selectively in the above various schemes, or the App can also switch independently or selectively in the above various schemes. By wearing the near-eye display device of this creation, any user can simply know the direction-related information or location-related information, and Enter a world of augmented reality without limits.
