In this paper, we will introduce two different three dimensional VR-based user interface for telecommunication network management. The first one is an immersive system, using HMD and other 3D input devices. The other is a WWW-based flat screen 3D collaborative user interface. The architecture of each system and our observation from it will be described. Then, a comparison will be made to show t...

M. Zhao, M. Bosma and G. de Haan Abstract The recent revolution in display technology enables bright highresolution displays, thereby removing one of the bottlenecks in video quality. We discuss how to profit from HD flat panel displays when watching legacy SD-video material. An overview of resolution upconversion techniques is presented, including an objective (MSEscores) and a subjective asse...

This paper presents a multi-touch system using vision-based algorithms that takes advantage of specular surfaces to detect and track finger locations with multiple cameras. The key innovation of the MirrorTrack approach is that by mounting cameras at a low azimuth to the horizontal display surface, the screen approaches a perfect mirror. Hence, we are able to track the user’s fingers together w...

In the present study, we examined the visual accommodation of subjects who were gazing fixedly at 3D images from two different displays: a cathode ray tube (CRT) while wearing special glasses and a liquid crystal display (LCD) while not wearing special glasses. The subjects in this experiment were two healthy people aged 22 and 39 years, all with normal vision. The instrument objectively measur...

The drive for greater detail in scientific computing and digital photography is creating demand for ultra-resolution images and visualizations. Such images are best viewed on large displays with enough resolution to show “big picture” relationships concurrently with fine-grained details. Historically, large scale displays have been rare due to the high costs of equipment, space, and maintenance...

2014 Based on the Oseen and Frank elastic continuum theory of nematic liquid crystals and on a generalized torque balance equation at the liquid crystal-to-substrate interface, static deformations of a semi-infinite liquid crystal (LC) medium, a homogeneous LC cell, and a twisted nematic cell have been investigated using the anisotropic LC-to-substrate anchoring energy C as a parameter. Storage...

As touch screens become widely spread, making them more accessible to visually impaired people is an important task. Touch displays possess a poor accessibility for visually impaired people. One possibility to make them more accessible without sight is through gestural interaction. Yet, there are still few studies on using gestural interaction for visually impaired people. In this paper we pres...

Many visual displays, such as movies and television, rely on sampling in the time domain. We derive the spatiotemporal-frequency spectra for some simple moving images and illustrate how these spectra are altered by sampling in the time domain. We construct a simple model of the human perceiver that predicts the critical sample rate required to render sampled and continuous moving images indisti...

The growth and evolution of nanometre-sized Ni metal islands deposited under low-temperature non-ultra high vacuum conditions as a function of metal layer thickness, growth temperature and time is reported. The temperature of formation of the islands has been intentionally kept low for possible applications in flat panel display technology and also to act as a catalyst for carbon nanotube growt...

Cars are ubiquitous and offer large and often highly visible surfaces that can be used as advertising space. Until now, advertising in this domain has focused on commercial vehicles, and advertisements have been painted on and were therefore static, with the exception of car-mounted displays that offer dynamic content. With new display technologies, we expect static displays or uniformly-painte...
