This paper discuss recent technological advances which provide opportunities for increasingly complex and fruitful interactions between users and information and communications technologies. It examines the need for personalization of interactions and the barriers to achieving this goal. A new paradigm of mediated interaction is introduced as a possible means of facilitating interactions with u...

In this paper, we describe techniques for barehanded interaction between human and computer. Barehanded means that no device and no wires are attached to the user, who controls the computer directly with the movements of his/her hand. Our approach is centered on the needs of the user. We therefore define requirements for real-time barehanded interaction, derived from application scenarios and u...

This paper considers ways in which a person can cue and constrain an artificial agent’s attention to salient features. In one experiment, a person uses gestures to direct an otherwise autonomous robot hand through a known task. Each gesture instantiates the key spatial and intentional features for the task at that moment in time. In a second experiment, which is work in progress, a person will ...

Computer interaction, animation and multimedia have changed cartography to a tremendous extent. This phenomenon requires new developments in cartographic theory and methodology. Especially interaction has influenced cartographic information processing decisively. Map-making and map-using have become one single and integrated process. The user is able to process and visualise data according to h...

computers in conversational speech has long been a favorite subject in science fiction, reflecting the persistent belief that spoken dialogue would be the most natural and powerful user interface to computers. With recent improvements in computer technology and in speech and language processing, such systems are starting to appear feasible. There are significant technical problems that still ne...

This chapter describes the area of human-computer interaction technique research in general and then describes research in several new types of interaction techniques under way at the Human-Computer Interaction Laboratory of the U.S. Naval Research Laboratory: eye movement-based interaction techniques, three-dimensional pointing, and, finally, using dialogue properties in interaction techniques.

Acknowledgments are relatively rare in humancomputer interaction. Are people unwilling to use this human convention when talking to a machine, or is their scarcity due to the way that spoken-language interfaces are designed? We found that, given a simple spoken-language interface that provided opportunities for and responded to acknowle d g m e n t s , abou t h a l f of our sub j ec t s u s e d...

ion: types and availability of abstraction mechanisms. Does the system give you any way of defining new facilities or terms within the notation, so that you can extend it to describe new things or to express your ideas more clearly or succinctly? What are they? Does the system insist that you start by defining new terms before you can do anything else? What sort of things? These facilities are ...
