In augmented reality games, the real world is blended with a virtual world. This certainly is something that sounds very cool and triggers imagination.
There are many different ways to create augmented reality (AR) games, often using image analysis. All of these methods are using a source of real-world images, such as a webcam or a smartphone’s camera.
Some of the possibilities:
- Marker objects placed in the real world are tracked, resulting in a 3D position, orientation and scale that can be used to position a 3D object, which may be animated.
- Using a device’s GPS and compass to determine the position of the player in the real world. This can be used for example to use real world positions for player interaction.
- Image analysis can be used to recognize shapes and objects, such as the outlines of a building or corners in a wall, human beings or animals, cars, etc.
A nice overview of possibilities that have already been tried out in games can be found in the augmented reality category at TouchArcade.
We have done substantial research on AR and developed an example prototype, which we’ll show in a next post.
