The sources of lag (the delay between input action and output response) and its effects on human performance are discussed. We measured the effects in a study of target acquisition using the classic Fitts' law paradigm with the addition of four lag ...

Information design is a new professional practice that systematically applies the lessons of human-computer interaction and human factors studies, communication theory, and information science to the presentation of complex data. WORLDESIGN, Inc., an ...

This panel brings together experts in the field of non-speech auditory displays with points of view ranging from long-term basic research in human perception to the timely production of useable tools in commercial systems. The panel will examine issues ...

Magicians have been designing and presenting illusions for 5000 years. They have developed principles, techniques and ethical positions for their craft that this paper argues are applicable to the design of human/computer interfaces. The author presents ...

Marquise is a new interactive tool that allows virtually all of the user interfaces of graphical editors to be created by demonstration without programming. A “graphical editor” allows the user to create and manipulate graphical objects with a mouse. ...

Auditory icons add valuable functionality to computer interfaces, particularly when they are parameterized to convey dimensional information. They are difficult to create and manipulate, however, because they usually rely on digital sampling techniques. ...

The human face is an independent communication channel that conveys emotional and conversational signals encoded as facial displays. Facial displays can be viewed as communicative signals that help coordinate conversation. We are attempting to introduce ...

Multimodal interaction enables the user to employ different modalities such as voice, gesture and typing for communicating with a computer. This paper presents an analysis of the integration of multiple communication modalities within an interactive ...

Mondrian is an object-oriented graphical editor that can learn new graphical procedures through programming by demonstration. A user can demonstrate a sequence of graphical editing commands on a concrete example to illustrate how the new procedure ...

Visual programming systems are supposed to simplify programming by capitalizing on innate human spatial reasoning skills. I argue that: (i) good visual programming environments should be oriented toward their application domains, and (ii) tools to build ...

In a distributed shared synthetic environment with provisions for high quality 3D visualization and interaction, it is possible to implement a powerful variant of a rooms/space metaphor based on the concept of presence or proximity between participants ...

The defining characteristics of what we call “Fish Tank Virtual Reality” are a stereo image of a three dimensional (3D) scene viewed on a monitor using a perspective projection coupled to the head position of the observer. We discuss some of the ...

An experimental 3D interface is described, including rendering acceleration hardware, a 3D mouse, and 3D interaction techniques. A 3D cursor, controlled by the augmented mouse, allows direct manipulation of 3D objects. Objects are selected by placing ...
