When a mobile device (notebook, smartphone, etc.) is used, the images on the monitor screen may be significantly distorted by a strong external light (for instance, sunlight) illuminating the screen surface. This additional illumination reduces all the local contrast values in the displayed images and leads to fading and deterioration of the subjective visual images thus impeding image recognit...

The Spinning Screen In screen-based experiences, the screen itself can become the physical device used for interaction. The “move-ability” of the screen affords interactivity between the screen artifact and the viewer and between the virtual space and the physical space. As a movable screen interface, I have created the spinning screen, a two-sided monitor mounted on a revolving base. This inte...

This paper presents a real-time, non-invasive, vision system which performs hands-free cursor control by having users point their nose where they wish to place the cursor on a monitor screen. The vision system robustly tracks 3D face position and orientation in real time using a framework called Incremental Focus of Attention (IFA). IFA integrates tracking based on multiple cues (including colo...

The information obtained from different reflections are recomposed back into a picture on the monitor screen (a sonogram, or ultrasonogram). Movements such as fetal heart beat and malformations in the feus can be assessed and measurements can be made accurately on the images displayed on the screen. Such measurements form the cornerstone in the assessment of gestational age, size and growth in ...

This paper aims to answer two questions. The first is how screen captures in software manuals should be used to support learning. Four functions of screen captures in software manuals are presented. Three studies report the influence of these functions on the effectiveness and efficiency of the learning process. The second question is how users of visual manuals process combinations of text and...

We had previously exploited a method for targeted DNA methylation in budding yeast to succeed in one-hybrid detection of methylation-dependent DNA-protein interactions. Based on this finding, we developed a yeast one-hybrid system to screen cDNA libraries for clones encoding methylated DNA-binding proteins. Concurrent use of two independent bait sequences in the same cell, or dual-bait system, ...
