چکیده
Attribute gates are a new user interface element designed to address the problem of concurrently setting attributes and moving objects between territories on a digital tabletop. Motivated by the notion of task levels in activity theory, and crossing interfaces, attribute gates allow users to opera-tionalize multiple subtasks in one smooth movement. We present two configurations of attribute gates; (1) grid gates which spatially distribute attribute values in a regular grid, and require users to draw trajectories through the attributes; (2) polar gates which distribute attribute values on seg-ments of concentric rings, and require users to align seg-ments when setting attribute combinations. The layout of both configurations of attribute gates was optimised based on targeting and steering laws derived from Fitts’ Law. A study compared the use of attribute gates with traditional contextual menus. Users of attribute gates demonstrated both increased performance and higher mutual awareness. © 2008 University of Newcastle upon Tyne.

AlphaSlider is a query interface that uses a direct manipulation slider to select words, phrases, or names from an existing list. This paper introduces a prototype of AlphaSlider, describes the design issues, reports on an experimental evaluation, and offers directions for further research. The experiment tested 24 subjects selecting items from lists of 40, 80, 160, and 320 entries. Mean select...
متن کاملPurkinje cell spike firing in the posterolateral cerebellum: correlation with visual stimulus, oculomotor response, and error feedback.
Complex (CS)- and simple-spike (SS) discharge from single Purkinje cells (Pc) in the posterolateral cerebellum of two monkeys was recorded during a visually guided reach-touch task. A visual target appeared (TA) off-gaze at a random location on a screen. On initiation of arm reach, the target disappeared, then reappeared (TR) after a fixed delay. TR was either at the same location (baseline con...
