Prediction, in its simplest meaning, is a claim that a certain event will happen in the future. Reaction, in contrast, is a response from some eliciting event. We look at the concepts through an online reaction-time game. Thirty-three participants rapidly clicked on circles appearing on different corners of the computer screen according to statistical regularities. Although a reactive strategy ...

How do adults represent arithmetic operations? One proposal is that addition is represented as rightward movement along a left-right mental number-line, whereas subtraction is represented as leftward movement (Hubbard et al., 2005). To test this proposal, 24 college students solved single-digit arithmetic problems displayed on a computer screen along with rightwardor leftward-moving dots. We hy...

E9.1.1 Visualization approaches The term Visualization Methods refers to a collection of tools and techniques from several disciplines. These methods take a collection of data and produce a visual display that gives insight into the structure of the data. Although the term can be used for static or paper displays, it is generally used to refer to visual displays of data shown on a computer scre...

Advances in technology and display hardware have allowed the resolution of monitors – and video games – to incrementally improve over the past three decades. However, little research has been done in preparation for the resolutions that will be available in the future if this trend continues. We developed a number of display prototypes to explore the different aspects of gaming on large, high-r...

This paper address the problem of obtaining from one web camera and a computer display, a facial reconstruction of the user within online messaging applications. In this paper we present a 3D shape recovery in real time based on the photometric information of a set of 4 images under varying illumination conditions. Our GPU implementation provides online realistic 3D face recontructions.

In this paper we present a new approach to displaying and browsing a digital library in Perseus that consists of a set of Greek vases. This approach is applicable to Digital Libraries in general, however. Our new design extends previous research by taking advantage of Virtual Reality to present context even while the user focuses on a single item. Using Virtual Reality, users are not limited to...

Emotional verbal messages are typically encountered in meaningful contexts, for instance, during face-to-face communication in social situations. Yet, they are often investigated by confronting single participants with isolated words on a computer screen, thus potentially lacking ecological validity. In the present study we recorded event-related brain potentials (ERPs) during emotional word pr...

We study the effect of haptic feedback intensity on touch typing performance on a flat keyboard. In this study, we investigate how local and global haptic feedback intensities affect typing performance and examine if haptic feedback at a higher intensity brings more performance benefit. We also investigate if auditory feedback intensity affects typing performance. Participants are asked to type...

To date most of the research concerning consumer health information has focused on trust and quality of health information websites. In this research, we observed 48 consumers searching for four health-related topics (some of their own choosing) using Google. Using transaction logs, video screen capture, retrospective verbal protocols and self-reported questionnaires, we examined holistically t...

Teleporting is the ability to redirect a windowing environment to different computer displays. This paper describes the implementation of a teleporting system developed at Olivetti Research Laboratory (ORL). We outline two particular features of the system that make it powerful. First, it operates with existing applications, which will run without any modification. Second, it incorporates sophi...
