Description

Virtual and augmented reality night vision goggles

This creation is about a night vision enhancement and virtual reality equipment, especially about a nighttime auxiliary and enhanced vision system equipment that is convenient to wear and use.

After more than 20 years of development, night vision goggles have gradually evolved from military use to general consumer goods. Even so, they are still unable to break free from the shackles of being bulky and requiring constant wear, so current night vision goggles have not been able to penetrate into the lives of the general public who need them.

Currently, night vision goggles are mainly divided into two categories: the first category is wearable night vision goggles, which are mainly used for military purposes. They use the night vision goggles bracket on the military steel helmet. When necessary, the device is installed on the bracket of the steel helmet and mechanically folded to the upper edge of the outer side of the steel helmet; when needed, the device is folded down and used to make it close to the user's eyes. Although this type of product is the mainstream for military use, it has many disadvantages as follows: 1. It is not easy to wear and store. When this type of product is installed on the bracket outside the steel helmet, it is easy to be damaged or displaced due to vibration or collision caused by the user's movement. Therefore, at this stage, users of this product need to carry a night vision goggles storage box for protection. 2. It is easy to get dizzy. The wearable night vision goggles have single-eye and double-eye designs. However, since the lens is used for close-range monochrome imaging, most users often get dizzy when using them. 3. The equipment is bulky. This type of night vision goggles has the common feature of being bulky. When wearing this type of product, the user will appear slow in movement and is prone to collisions. 4. The power supply time is short. This type of night vision goggles mainly use batteries as power supply. However, the battery is built into the device, which makes the device bulky. Because of the limited space and weight, the normal use time that can be provided is very short. Usually, the power-on time can only be maintained for less than four hours.

The second category is portable night vision goggles. These night vision goggles are similar to traditional telescopes, with a huge difference in size. However, they also have many disadvantages as follows: 1. Inconvenient to carry. Since these devices are similar to traditional telescopes, they are large and bulky. 2. Inconvenient to use. Since they cannot be worn, they usually still need to be operated with both hands when used; that is, when using such devices, both hands cannot be freed for other purposes. 3. Poor practicality. Since they cannot be worn, they are greatly limited in application and can only be used as telescopes.

Current night vision goggles mainly obtain external images through cameras, and the processed video signals are displayed on the LCD screen through the signal analysis and processing unit. Current wearable night vision goggles are limited by the size of the equipment and use lenses to directly shine into the user's eyes for imaging, so users often get dizzy and cannot be used for a long time. Current portable night vision goggles mainly use LCD screens to image, which is less likely to cause dizziness to users, but because they require two-handed operation, they are not very practical and are difficult to integrate into the daily life of ordinary people.

Therefore, whether it is military or civilian consumption, everyone is looking forward to a new night vision goggles that can overcome the above shortcomings and popularize the application of night vision function for the public. In response to the public's expectations, this creation can greatly correct the above shortcomings and simplify the wearing and operation. Users will be able to fully utilize the night vision enhancement function provided by this creation.

In view of the above problems and deficiencies, the creator has invested a long time in research and development and created a new enhanced lightweight wearable night vision goggles that are completely different from the existing night vision goggles. This creation will simplify the wearing and carrying procedures, greatly reduce the user's dizziness, avoid the user's clumsy feeling when using night vision goggles, and can be popularized and integrated into the lives of the general public.
