The paper presents a graphical extension to the IEC 61131-3 CPDev programming environment. The extension called CPVis provides development tools and runtime components to create an operator interface for control software. CPVis editor is used to design display pages. Graphic objects are selected from libraries and represent visual controls on the display. The target operator panel runs CPVis gr...

A novel stereoscopic image rendering method for autostereoscopic mobile devices is presented in this paper. The system to implement the proposed method consists of autostereoscopic display system and the stereoscopic rendering software engine for mobile devices. First, we mount a parallax barrier, which is made by a twisted nematic (TN) panel, on the liquid crystal display (LCD) to display ster...

In this article we explore the strengths and limitations of hypertext for the online presentation of thesauri used in information retrieval. We examine the ability of hypertext to support each of three common types of thesaurus display: graphic, alphabetical, and hierarchical. Graphic displays generated by hypertext browsers appear to be inferior to their printed counterparts. The simple alphab...

Visual Agents are software entities which assist people in performing graphical tasks. One useful and interesting graphical task is to make a textand-graphic record of a group meeting. When the recording is done live ill view of the group on a large display, such as on a whiteboard, it is a performing art which can be called "Group Graphics." During group graphics, collaboration is enhanced bec...

The performance of graphics display of virtual machine improves with the strong support from development of virtualization technology and computer hardware. However, in terms of graphical display mechanism there is a difference between the virtual environment and the traditional environment. So how to measure the performance of graphics display in virtualization environment effectively is espec...

Despite current advances in multimedia environments, tracing the geometrical structures of graphical images using force feedback remains an important research issue. In this paper, the development and implementation of a Multi-Modal Display System (MMDs) for tracing 2D boundaries in graphic images are discussed. A method is proposed that provides a type of haptic feedback designed to assist a u...

Laser projection, such as that used in laser light shows, usually uses computer-drawn graphics. However, some restrictions are imposed by laser-scanned displays on these vector-based drawings. This paper presents a general vector-oriented drawing method to display computer vector graphics on different laser-scanned displays with optimization. The method considers how to solve the three fundamen...
