Hybrid Magic Lens
Previous studies identified shortcomings of the magic lens interaction paradigm that range from poor information browsing task performance to undesired effect of the dual-view problem degrading user’s ability to relate augmented content to the real world and users’ ability to use the existing contextual information. In this project we explore how a hybrid magic lens approach could improve such interaction. In other words, how designing a magic lens with more than one view can benefit the user.

Dual-view and the Magic Lens: User vs. Device-perspective Rendering
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). Unfortunately, in common AR implementations these two do not match. In this project we uncover how this mismatch affects the users.

Enhanced virtual transparency
In this project we looked at different ways of imporving virtual transparency of the Magic Lens. We looked at how to improve depth perception when looking through the magic lens utilizing paralax berrier stereoscopic displays and how to improve scene readability utilizing high resolution textures.

Sensor fusion for imporved augmentation context
In this project we looked at different ways of imporving the context of augmentation in handheld AR. We looked at the possiblity of introducing scale utilizing autofocusing capability of the camera phone and the depth-from-focus technique. We also looked at how one can simplify initalization of planar maps utilizing on device accleorometers.
