A smart phone has a small-sized display, but a most powerful platform for context-awareness in ubiquitous computing because it has a sensitive camera and a bright display, and can detect the location using a GPS receiver, compass and accelerometer [31].
Hwang et al. [34] found that users in mobile AR felt immersed in the content shown on the handheld display.
Since the smart phone affords context immersion in AR, the mobile AR applications do not generate the presence as being in the virtual world exclusively, but enable the users to understand what happens in the real world as well as the virtual world.
