Despite the considerable quantity of research directed towards multitouch technologies, a set of standardized UI components have not been developed. Menu systems provide a particular challenge, as traditional GUI menus require a level of pointing precision inappropriate for direct finger input. Marking menus are a promising alternative, but have yet to be investigated or adapted for use within multitouch systems. In this paper, we first investigate the human capabilities for performing directional chording gestures, to assess the feasibility of multitouch marking menus. Based on the positive results collected from this study, and in particular, high angular accuracy, we discuss our new multitouch marking menu design, which can increase the number of items in a menu, and eliminate a level of depth. A second experiment showed that multitouch marking menus perform significantly faster than traditional hierarchal marking menus, reducing acquisition times in both novice and expert usage modalities.
Medical computing systems rely primarily on traditional human-computer interfaces, such as the keyboard, mouse and touch screen, however future systems will incorporate vastly enhanced interaction capabilities. Some of these, such as speech control and eye contact sensing, have begun to appear on the medical computing landscape. Eye contact provides computer systems with a wealth of yet-uncollected information about user attention and attentiveness, and may allow for personalized interfaces, while requiring almost no training to use. This paper introduces an advanced prototype of a gaze-enhanced speech recognition charting system for surgical nurses. We go on to discuss the implications of our system and of gaze detection in general for medical computing.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
