Multiple-Degree of Freedom Adjustable Discrete Type Near-Eye Display Device

FIELD

The present invention relates to a discrete type near-eye display device. In particular, it relates to a discrete type near-eye display device, which allows the near-eye display included in the near-eye display device to have a simply adjustable position with respect to a user's head in multiple-degree of freedom.

BACKGROUND

In the state of the art, a near-eye display device, also known as, a near-to-eye display device, is a type of novel wearable device that provides a display right in front of a user's eyes and the user's line of sight, to show various digital contents in forms of, such as, images, graphics, texts, videos, audios, received and sent from, such as, a main board module, electronic sensors, a smart phone, a tablet or a notebook computer, on the display for the user to see. In general the near-eye display device is used to be an output interface for the main board module, the electronic sensors, the smart phone, the tablet or the notebook computer.

The display utilized in a near-eye display device may be transparent or opaque, and accordingly the device is generally categorized into two major types, which the first major type is a transparent or semi-transparent type near-eye display device, as known as, a see-through type near-eye display device, while the second major type is an opaque type near-eye display device. For an opaque type near-eye display device, an opaque display is utilized in the near-eye display device and shows digital contents to a user. The opaque-type device can use the conventional liquid crystal based panel as the opaque display and is much easier to create an immersive theater-like visual experiences for the user, as compared with the transparent type near-eye display device. The opaque-type near-eye display device is often applied as a tool and technology to realize and implement a virtual reality (VR).

As to a transparent or semi-transparent type near-eye display device, a see-through display is used in the device, which the see-through display allows a user to see the surrounding in the reality world through a see-through display while in the meantime the digital contents shows on the transparent display. The user can clearly see the real world and the digital contents in the meantime through the transparent or see-through display. The transparent type near-eye display device is often applied as a tool and technology to realize and implement an augmented reality (AR). Visually the reality world appears to act as a background for the see-through display while the transparent display shows digital contents, which is so cool and fascinating. Nowadays there are many kinds of see-through display based product available on the market, such as, the Microsoft HoloLens product, and the Epson Moverio BT-300 smart glass product. Although these products are able to provide astonishing and amazing visual experiences for users, these products inevitably have multiple significant shortages and deficiencies as follows.

Typically the designs of these products are focused on building and putting all kinds of electronic module and components together into a product based on one-single piece, which significantly causes the products gaining too much extra weight, and relatively large size. Therefore these products are actually too big to wear on a user's head. Actually a head wearable product with large size might look so strangle and possibly draws many unnecessary attentions when wearing on a user' head. What is even more important is when a user wears these products on the head, for example, the user certainly feels clumsy and uncomfortable and looks weird, due to the improper load distribution and the concentrated weight on the product, and its strangle funny appearance. Nevertheless, an additional significant deficiency for these products is that positions of these products with respect to the user's head are hardly adjusted.

There is a need to solve the above deficiencies/issues.

As shown in FIGS. 11(a)-11(c), for the near-eye display device 100, when it is in use by a user, the attaching unit 140, for example, the cord, surrounds a user's forehead and must extend and pass by user's ears. Therefore a pair of earphones 500, in particular, a pair of bone conduction earphones, is basically designed to deploy on a position close to user's ears on the attaching unit 140.

FIG. 12(a) is a front view schematic diagram depicting the near-eye display device in use and worn by a user in accordance with the present invention which the near-eye display device has a nose pad configured on the sensor assembly for a user requiring to wear glasses; FIG. 12(b) is a side view schematic diagram depicting the near-eye display device in use and worn by a user in accordance with the present invention which the near-eye display device has a nose pad configured on the sensor assembly for a user requiring to wear glasses; FIG. 12(c) is a side view schematic diagram depicting the near-eye display device in use and worn by a user wearing the glasses in accordance with the present invention which the near-eye display device has a nose pad configured on the sensor assembly.

As if a user is short-sighted and has to wear glasses 610 or spectacle, an additional optional accessory, a nose pad 600, is added to the near-eye display device 100. The nose pad 600 is preferably mounted at the bottom side of the sensor assembly 110, and able to provide more support for the sensor assembly 110 in addition to the attaching unit 140, so as to prevent the sensor assembly 110 from sliding downward gradually from user's head 200 and create more space for the vacancy for containing the glasses 610 available under the sensor assembly 110. Therefore, when a user requires wearing glasses 610, the nose pad 600 is able to support the sensor assembly 110 up to prevent the sensor assembly 110 from moving downward resulting in pushing the glasses 610 the user is wearing.
