Location-based and recognition-based augmented reality are the two main types of augmented reality. Both types try to derive where the user is looking. This information is key in the augmented reality process, and relies on properly calculating the camera pose estimation. In order to accomplish this task, the two types are briefly described as follows:
- Location-based augmented reality relies on detecting the user's location and orientation by reading data from several sensors, that are very common in smartphone devices (for example, GPS, digital compass, and accelerometer) to derive where the user is looking. This information is used to superimpose computer-generated elements on the screen.
- On the other hand, recognition-based augmented reality uses image processing techniques to derive where the user is looking. Obtaining the camera...
