Annotating documents helps us to note our thoughts and pass knowledge and insights to others. However, pen-and-paper annotations can be difficult to share or disseminate, and are generally constrained by a document's available margin space. Thus, prior work has explored the value of linking digital information to physical documents in augmented reality (AR). The smartphone comprises a commonly accessible digital device, but its small screen size and touchscreen interface make it yet ill-suited for annotating....

Free-hand manipulation in smartphone augmented reality (AR) enables users to directly interact with virtual contents using their hands. However, human hands can ergonomically move in a broader range than a smartphone's field of view (FOV) can capture, requiring users to be aware of the limited usable interaction and viewing regions at all times...

What if we could play with augmented reality (AR) objects with our hands directly instead of clicking on the smartphone screen? Portal-ble enables such AR experience by introducing a series of feedback mechanisms on top of our open-source mobile hand tracking application. The result is a more intuitive, easy to use hand interaction experiences on your everyday mobile devices!

In this paper, we studied15 participants’ preferences, performances, and cognitive loads on a set of common tasks performed on smartphones at two interaction depths (close-range and distant) with two touchless modalities(hand tracking and screen dwell)...See more

A large portion of remote user studies is done on mobile devices, and most focused on users' screen inputs. Remotion provides further contextual information by replaying user hand movements using our custom-made robotic holder. We found that motion cues reveal characteristics and engagement level of participants that the screen inputs do not.
