The use of surrounding visual context in handheld AR
Klen Čopič Pucihar, Paul Coulton, Jason I. Alexander · 2014
The magic lens paradigm, a commonly used descriptor for handheld Augmented Reality (AR), presents the user with dual views: the augmented view (magic lens) that appears on the device, and the real view of the surroundings (what the user can see around the perimeter of the device). The augmented view is typically implemented by rendering the video captured by the rear-facing camera directly onto the device's screen. This results in dual perspectives - the real world being captured from the device's perspective rather than the user's perspective (what an observer would see looking through a transparent glass pane). These differences manifest themselves in misaligned and/or incorrectly scaled transparency resulting in the dual-view problem.
