Wavelet menus

Abstract

Exploration and navigation in multimedia data hierarchies (e.g., photos, music) are frequent tasks on mobile devices. However, visualization and interaction are impoverished due to the limited size of the screen and the lack of precise input devices. As a result, menus on mobile devices do not provide efficient navigation as compared to many innovative menu techniques proposed for Desktop platforms. In this paper, we present Wavelet, the adaptation of the Wave menu for the navigation in multimedia data on iPhone. Its layout, based on an inverted representation of the hierarchy, is particularly well adapted to mobile devices. Indeed, it guarantees that submenus are always displayed on the screen and it supports efficient navigation by providing previsualization of the submenus.

Investigating Performance and Usage of Input Methods for Soft Keyboard Hotkeys

“…Researchers though have long explored how different modalities, such as gestural interaction, could be adapted to facilitate command selection on touch-based devices. The widely studied marking menus [28] have influenced many stroke-based strategies [4,14,15,25,32,47] to trigger commands on multitouch platforms. Similarly, MelodicTap [22] and Arpège [16] investigated rhythmic chorded gestures to expand input vocabulary on touch screens.…”

HotStrokes

“…Many other interfaces use somewhat arbitrary gestures, but provide visual guidance for novices to facilitate learning. On touchscreen devices, Marking Menu [21,24,25] and its variants [5,6,11,12,46,47] allow novices to "press and hold" to expand a hierarchical menu and trace through menu labels to form a gesture, while experts may approximate the same gesture without depending on any guidance. OctoPocus [7] expands this idea, but only shows what gestures are possible when users pause their fingers.…”
