To illustrate the potential of multilayer neural networks for adaptive interfaces, a VPL Data-Glove connected to a DECtalk speech synthesizer via five neural networks was used to implement a hand-gesture to speech system. Using minor variations of the standard backpropagation learning procedure, the complex mapping of hand movements to speech is learned(More)
We propose a linear programming relaxation scheme for the class of multiple object tracking problems where the inter-object interaction metric is convex and the intra-object term quantifying object state continuity may use any metric. The proposed scheme models object tracking as a multi-path searching problem. It explicitly models track interaction, such(More)
We explore a variety of design criteria applicable to the creation of collaborative interfaces for musical experience. The main factor common to the design of most collaborative interfaces for novices is that musical control is highly restricted, which makes it possible to easily learn and participate in the collective experience. Balancing this tradeoff is(More)
We report preliminary results of our ongoing field study of IT professionals who are involved in security management. We interviewed a dozen practitioners from five organizations to understand their workplace and tools. We analyzed the interviews using a variation of Grounded Theory and predesigned themes. Our results suggest that the job of IT security(More)
Glove-TalkII is a system which translates hand gestures to speech through an adaptive interface. Hand gestures are mapped continuously to ten control parameters of a parallel formant speech synthesizer. The mapping allows the hand to act as an artificial vocal tract that produces speech in real time. This gives an unlimited vocabulary in addition to direct(More)
In this paper we describe three new music controllers, each designed to be played by two players. As the intimacy between two people increases so does their ability to anticipate and predict the other’s actions. We hypothesize that this intimacy between two people can be used as a basis for new controllers for musical expression. Looking at ways people(More)
In this paper, we explore the practice of using a whiteboard for multiple tasks, and specifically how users employ whiteboards to smoothly transition between related sets of tasks. Our study underscores several basic, but important affordances of whiteboards that support this practice, including visual persistence, flexibility of interaction primitives, and(More)
