7. Context – Augmented Reality
¤ Augmented Reality enriches information
¤ 3D models, 2D informative labels
¤ Illusion that what is real and what is virtual
coexist in the same space. [Azuma-1997]
¤ A new kind of human-computer interaction.
¤ Two main approaches
¤ Specialized Devices
¤ Smartphone and tablets
