Understanding Augmented Reality
What is Augmented Reality?
Augmented Reality (AR) is a technology that superimposes digital content such as 3D models, images, videos or sounds onto the real world through a device such as a smartphone, tablet, or smart glasses. AR enhances the user’s perception of the real world by adding a layer of digital information to it, creating a mixed reality experience. AR can be used in various industries such as gaming, education, healthcare, and more.
Types of Augmented Reality
There are three main types of augmented reality:
Marker-based AR: This type of AR uses a marker or a specific image to trigger the display of digital content. When the device’s camera detects the marker, it superimposes the digital content on top of it.
Markerless AR: This type of AR uses the device’s sensors such as GPS, accelerometer, and gyroscope to track the user’s position and orientation. Digital content is then overlaid onto the real world based on the user’s location and movement.
Projection-based AR: This type of AR projects digital content onto real-world surfaces such as walls or floors. The projection can be interactive, allowing users to interact with the digital content.
Understanding the basics of augmented reality is essential to creating 3D models for AR. By knowing the types of AR, you can choose the best approach for your project. AR has the potential to revolutionize the way we interact with the world around us, and by creating 3D models for AR, you can be a part of this exciting future.
