AR augmented reality technology is more and more widely used, which has important application value from games, entertainment to medical care, industry and other fields. However, in order to realize AR augmented reality, some hardware devices are needed. This paper will introduce what hardware devices are needed for AR augmented reality.
The first is the display device. The basic function of AR augmented reality is to project virtual images into the real world, so a display device is needed to realize this function. The display of AR equipment can be in different forms, such as head-mounted, hand-held and flat-panel, among which head-mounted displays such as Oculus and HoloLens are the most typical. These devices project virtual images into real scenes through headphones or glasses, forming an experience that seems real.
Followed by sensor equipment. An important function of AR augmented reality is to identify the environment in real time and connect with the virtual world, so sensor devices need to collect environmental information in real time. There are many kinds of sensor devices, mainly including cameras, GPS, inertial sensors, temperature sensors and so on. Using these sensor devices, AR devices can capture the user's position, trajectory, rotation angle, ambient brightness and other information in real time, so as to better connect with the real world.
Once again, computing devices. AR augmented reality needs complex image processing algorithms, so it needs computing equipment with powerful computing power to support it. Nowadays, most AR devices use mobile computing devices, such as smart phones and tablets, which have strong computing power. At the same time, some high-end AR devices also use computing devices in the form of computing sticks and cloud servers to improve processing speed and accuracy.
Finally, interactive devices. AR augmented reality needs to interact with users to play its real value, so it needs some interactive devices to realize it. The types of interactive devices include handles, gloves, voice recognition, touch screens and so on. Through these interactive devices, users can interact with virtual objects, control virtual models or perform specific operations, so as to better experience the functions of AR augmented reality.
In a word, AR augmented reality needs a variety of hardware devices, including displays, sensors, computing devices, interactive devices and so on. The continuous updating and development of these devices provide better support for the application scenarios and user experience of AR augmented reality.
