Mixticky: A Smartphone-Based Virtual Environment for Recordable and Browsable Multimedia Stickies

We propose "Mixticky," a scheme for browsing and recording memorandum-like sticky notes in a three-dimensional virtual space around a user with a smartphone. For intuitive browsing and recall of such memos and information, it is important to achieve browsability and contemporaneousness of the memos/information. Mixticky allows the user to place and peel off memos on a virtual balloon around her/him corresponding to each relative direction (e.g., front, left, or 45° from front to right). The user can record and browse voice, movie, image, handwriting, and text memos as virtual sticky notes in each direction by pointing the phone. The system employs snapping gestures with the smartphone as metaphors for the "put" and "peel off" motions corresponding to a physical sticky note. The virtual balloon can be carried in various scenarios so that the user can easily resume her or his thought processes anywhere.
