The remarketing of used flat screen desktop monitors is evolving into a profitable market segment. Demand for used or non-functional monitors is growing especially in Eastern European countries and cannot be covered by End-of-Life (EoL) products, yet. Non-functional phase-out models are often sold to repair-shops in Eastern European countries, which is often associated with improper EoL treatme...

isually impaired people (VIP) have difficulty interacting with computer systems that present the majority of their output visually. VIP who have no functional sight can use screen readers— assistive programs that present the visual output as speech or that drive refreshable Braille displays. 1 The most widespread example of such software is Microsoft Narrator, a screen reader that ships with Wi...

A new algorithm is proposed for novel view generation in one-toone teleconferencing applications. Given the video streams acquired by two cameras placed on either side of a computer monitor, the proposed algorithm synthesises images from a virtual camera in arbitrary position (typically located within the monitor) to facilitate eye contact. Our technique is based on an improved, dynamicprogramm...

Thirty smokers and 30 nonsmokers participated in a “flicker” study to examine the role of attentional bias in change detection. Participants observed picture-pairs of everyday objects flicker on the computer screen until they detected the one object that changed. In half of the pictures, a smoking-related object (e.g., lighter) was included among smoking-unrelated objects (e.g., spoon). Half of...

Drawing the user’s gaze to an important item in an image or a graphical user interface is a common challenge. Usually, some form of highlighting is used, such as a clearly distinct color or a border around the item. Flicker can also be very salient, but is often perceived as annoying. In this paper, we explore high frequency flicker (60 to 72 Hz) to guide the user’s attention in an image. At su...

INTRODUCTION Moderate capability simulators such as Laerdal's SimMan allow for the operator to control the vital signs presented on the monitor. However, the presence of the mannequin simulator may not always be needed to achieve specific teaching goals. In this report, we describe the use of the SimMan software to generate, control, and project vital signs on a projector screen, with an appear...

Ruled surface design and its applications are widely used in CAGD(Computer Aid Geometric Design) and industrial areas. In this paper, the hyperbolic paraboloid is a particular ruled surface, which is drawn by using the dual De Casteljau algorithm [15]. The characteristics of the hyperbolic paraboloid are analysed in order to match the requirement of the dual De Casteljau algorithm. A new method...

Ruled surface design and its applications are widely used in CAGD (Computer Aided Geometric Design) and industrial areas. The hyperbolic paraboloid, the cylinder, the cone, and the hyperboloid are ruled surfaces with particular shapes. In this paper, dual space drawing methods for these particular ruled surfaces are proposed. The underlying principles of these methods are the applications, exte...
