“…Oh and Hua tested various aspect ratios and sizes of spatially aware peepholes [18]. They concluded that the aspect ratio of a display plays a more important role for smaller screens than for larger ones and that screen sizes are more dominant in impacting the user performance.…”

The multi-touch-based pinch to zoom, drag and flick to pan metaphor has gained wide popularity on mobile displays, where it is the paradigm of choice for navigating 2D documents. But is finger-based navigation really the gold standard? In this paper, we present a comprehensive user study with 40 participants, in which we systematically compare the Pinch-Drag-Flick approach with a technique that relies on spatial manipulation, such as lifting a display up/down to zoom. While we solely considered known techniques, we put considerable effort in implementing both input strategies on popular consumer hardware (iPhone, iPad). Our results show that spatial manipulation can significantly outperform traditional Pinch-Drag-Flick. Given the carefully optimized prototypes, we are confident to have found strong arguments that future generations of mobile devices could rely much more on spatial interaction principles.

“…Researchers have looked into these questions via simulation [21,17] and via real AR magic lenses [25,26]. Oh et al [21] looked at the effects of magic lens display size and screen aspect ratio on a search and a path following task. Their results indicated that, in general, a larger magic lens was better for searching while a smaller magic lens was better for path following.…”

In this paper we present a user study evaluating the benefits of geometrically correct user-perspective rendering using an Augmented Reality (AR) magic lens. In simulation we compared a user-perspective magic lens against the common device-perspective magic lens on both phone-sized and tablet-sized displays. Our results indicate that a tablet-sized display allows for significantly faster performance of a selection task and that a user-perspective lens has benefits over a device-perspective lens for a selection task. Based on these promising results, we created a proof-of-concept prototype, engineered with current off-the-shelf devices and software. To our knowledge, this is the first geometrically correct userperspective magic lens.

“…Even though the designed task is artificial, this interaction pattern is analogous to navigation and route-planning on augmented paper maps. Additionally, as Oh and Hua used a similar methodology, it was deemed appropriate [21].…”

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. This paper presents two user studies comparing (a) deviceperspective and (b) fixed Point-of-View (POV) userperspective magic lenses to analyze the effect of the dualview problem on the use of the surrounding visual context. The results confirm that the dual-view problem, a result of dual perspective, has a significant effect on the use of information from the surrounding visual context. The study also highlights that magnification and not the dual-view problem is the key factor explaining the correlation between magic lens size and the increased intensity of the magic lens type effect. From the results, we derive design guidelines for future magic lenses.
