The author describes a recent composition for piano and computer in which the score performed by the pianist, read from a computer display, is generated in real-time from a vocabulary of predetermined scanned score excerpts. The author outlines the algorithm used to choose and display a particular excerpt and describes some of the musical difficulties faced by the pianist in a performance of th...

Many theories have been developed that attempt to explain innovation-driven organizational transformation, each with their respective models. Most process models use geometric shapes to represent variables of interest, and lines and arrows to show effects and relationships. While these models are useful for illustrating direct causality, they are less useful for illustrating more complex intera...

Computer visualizations are all around us. In this paper we describe a design process in which we explore the development of a new visualization to aid managerial decision making. The ultimate goal of our design effort is to develop a visualization that allows for presenting most of the critical financial ratios used to describe a firm’s activity on a single computer display and dynamically. In...

Recent models of predator search behavior integrate proximate neurobiological constraints with ultimate economic considerations. These models are based on two assumptions, which we have critically examined in experiments with blue jays searching for artificial prey images presented on a computer monitor. We found, first, that when jays had to switch between searching for two distinct prey types...

Critics of hypertext have long expressed skepticism about whether people could or indeed ever would sit down at a screen and read hypertexts. They may cite the more general problems of reading from the computer screen (see, for example, [25]) or they may place the blame partially at the feet of the authors (see, for example, Birkerts’ indictment of hypertext fiction [8][2]). Some have even put ...

In this paper, we propose a personalized display, “AwareMirror : an augmented mirror”. AwareMirror presents information relevant to a person in front of it by super-imposing his/her image. A toothbrush has been chosen as an identification tool while proximity sensors have been utilized to detect a person’s position (in front of the mirror). Also, three types of information that can affect a use...

In this research, we present the concept of Hyperaudio as non-linear presentation of auditory information in the context of underlying theoretical assumptions of how Hyperaudio differs from existing non-linear information media. We present a study comparing text and auditory represented information either in a linear or non-linear manner and the interaction of these presentation formats with di...

This study investigates the effect of grammatical aspect marking in Dutch sentences, on speakers’ estimations of the duration of highly familiar, everyday events. We first established the ‘inherent’ or natural duration of different events (Exp. 1). This was then used for the manipulation of aspect (Exp. 2). Participants dragged a slider across the computer screen to estimate the duration of pro...

When writing on a computer, paper may be used as a complement to the computer screen for planning, text production, and revision. MY STUDIES • Two questionnaire studies among university students on how they wrote a paper for a course • Focusing on how paper was used as a complement to the computer MY RESULTS • About half the students used the outlining function in the word processor • Most stud...
