Multi-point interaction tasks involve the manipulation of several mutually-dependent control points in a visual workspace ? for example, adjusting a selection rectangle in a drawi...
We investigate pointing at graphical targets of arbitrary shapes. We first describe a previously proposed probabilistic Fitts' law model [7] which, unlike previous models tha...
In this paper, we present initial findings from the study of a digital photo-sharing website: Flickr.com. In particular, we argue that Flickr.com appears to support--for some peop...
In this paper, we present a study of user perceptions on mobile interaction with visual and RFID tags. Although mobile interaction with tags has been proposed in several earlier s...
A computational composite is a material in which computations contribute to the properties of the material through their capability to control transitions between states in the oth...
