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...

This paper introduces the Human Information Workspace (HISpace) as a test-bed for evaluating new information exploration mechanisms. In moving from dated interaction devices and small computer monitors, we aim to utilize more natural surfaces such as tables and walls as our interaction space. In testing our theories, we have produced a number of gaming applications as test cases. Here, we repor...

With the recent emergence of a wide range of information displays that reach beyond the traditional graphics-based computer screen, it seems that the original definition of ambient display, and its focus on user attention and aesthetics, has become diluted. Instead, we propose a taxonomy of alternative information displays that is mainly based on context, in terms of the data it represents and ...

Given a collection of images of offices, what would we say we see in the images? The objects of interest are likely to be monitors, keyboards, phones, etc. Such identification of the foreground in a scene is important to avoid distractions caused by background clutter and facilitates better understanding of the scene. It is crucial for such an identification to be unsupervised to avoid extensiv...

Consider the problem of visualizing high-dimensional data that has been categorized into various classes. Our goal in visualizing is to quickly absorb inter-class and intra-class relationships. Towards this end, class-preserving projections of the multidimensional data onto twodimensional planes, which can be displayed on a computer screen, are introduced. These class-preserving projections mai...

A P300 Speller is a brain–computer interface (BCI) that enables subjects to spell text on a computer screen by detecting P300 Event-Related Potentials in their electroencephalograms (EEG). This BCI application is of particular interest to disabled patients who have lost all means of verbal and motor communication. Error-related Potentials (ErrPs) in the EEG are generated by the subject’s percep...

High-Order Wavefront Aberration Regularized Deconvolution (HOWARD) is a complete closed loop system developed for simulating human visual function with the primary goal of enhancing graphic computer displays for users that have refractive errors (resulting in difficulty interacting with visual displays). Visual function is a primary requirement for a human being to engage in computer usage effi...

PURPOSE An analytical and experimental study of split shape dose calculation correction by adjusting the position of the on-axis round leaf end position is presented. We use on-axis corrected results to predict off-axis penumbra region dosimetric performance in an intensity-modulated radiation therapy treatment planning system. MATERIALS AND METHODS The precise light-field edge position (X(ta...

Statistical process control methods for monitoring processes with univariate ormultivariate measurements are used widely when the quality variables fit to known probabilitydistributions. Some processes, however, are better characterized by a profile or a function of qualityvariables. For each profile, it is assumed that a collection of data on the response variable along withthe values of the c...
