Semantic interoperability should not only cover system interpretation of incoming information, but should be extended to include screen representation. This article describes a two-model approach to generate a screen representation for archetype-based information, which is inspired by the two-model approach used by openEHR for their archetypes. It provides a separation between software-related ...

A system which displays information graphically, and also allows natural language queries, should allow these queries to interrogate the displayed (visual) information. Ideally this would use some uniform method for processing queries both about the display and about the world model. Such a system would have to cope with ambiguities introduced by these two sources of information. These ambiguit...

Embedded products have different types of display screens like LCD, Touch screen, CRT etc. For automating the development testing of such devices, we need to recognize the text displayed on it using a camera. It is always a challenge to recognize the LCD display screen using OCR engines. Due to the custom display nature of these LCD controllers as well as the small font size, character recognit...

Recent developments in touch and display technologies made it possible to integrate touch-sensitive surfaces into stereoscopic three-dimensional (3D) displays. Although this combination provides a compelling user experience, interaction with stereoscopically displayed objects poses some fundamental challenges. If a user aims to select a 3D object, each eye sees a different perspective of the sa...

We describe here the first working prototype of a novel display for viewing 3D medical images. The position and orientation of a freely movable touch-screen display are optically tracked and used to continuously determine which slice to display within a 3D data set. The slice is registered “in situ” relative to a fixed coordinate system, through which the display is moved. We have coined the te...

Today's large-size computer screens can display a wealth of information easily enough to overload the user's visual perceptual channel. Looking for a remedy for this effect, we research into providing additional acoustic cues through surround sound speakers mounted around the screen. In this paper, we demonstrate the results of user evaluations of interaction with screen elements using the surr...

This paper describes the CECA VisLab Tiled Display—a reconfigurable, multi-screen, multi-computer, distributed image display system with zoom and pan functions. The project software utilizes distributed computing algorithms to control a parallel system to render high resolution images and scientific data on multiple displays. The system extends open source software to provide a large tiled imag...

In this paper, we propose a wide-viewing-angle three-dimensional integral imaging using a curved screen and a curved lens array. Elemental images are projected to the curved screen. Incorporation of the curved screen and the curved lens array instead of a conventional flat display panel and a flat lens array expands the viewing angle remarkably. In addition adopting barriers between a curved le...
