Modeling is a key activity in system analysis and design. Users as well as stakeholders, experts and entrepreneurs need to be able to create shared understanding about a system representation in various phases of a design process. In each of these phases it is important to align views and ensure that differences in understanding of the system are resolved. Visualization is of high importance in...

In this paper we present a software whiteboard for multimedia conferences. The whiteboard is specialised to load and share high-resolution colour images while using colour management functions to provide an accurate colour representation. The whiteboard is used in the telemedicine project INTER-FACE, which builds a virtual environment for tele-consultations between specialists in pre-operative ...

The focus of research into the use of the interactive whiteboard (IWB) in the classroom has been largely in relation to teacher–pupil interaction, with very little consideration of its possible use as a tool for pupils’ collaborative endeavour. This paper is based upon an ESRC-funded project, which considers how pupils use the interactive whiteboard when working together on science-related acti...

Many whiteboard applications have been developed during the recent years. In distributed settings, where whiteboards have to be synchronized, proprietary protocols are often used for communication. Using reliable and wellknown open standards can ease integration with existing systems. After evaluating existing instant messaging protocols, we look at applying those well-established standards for...

We present an online, interactive tool for writing and presenting interactive geometry demos suitable for classroom demonstrations. Code for the demonstrations is written in JavaScript using p5.js, a JavaScript library based on Processing. 1998 ACM Subject Classification F.2.2 Nonnumerical Algorithms and Problems – Geometrical problems and computations

In recent years, the use of technological tools to enhance the delivery of teaching materials has gained popularity in universities and has brought positive improvements in the classroom. With advanced hardware, instructors can hand-write notes onto their computer electronically and shared it with the students. While with advanced educational collaborative software, instructor and students can ...

A treatment/control study (N = 773) was conducted to determine the extent to which use of interactive whiteboard technology (IWB) was associated with upper element...

We report from a case study of the implementation of an electronic whiteboard system at two emergency departments at Danish hospitals. The purpose of the whiteboards is to support the clinicians in maintaining an overview of the patients at the departments. The electronic whiteboard system was designed in collaboration with clinicians from the departments. Compared to existing dryerase whiteboa...

We explore the combination of smartwatches and a large interactive display to support visual data analysis. These two extremes of interactive surfaces are increasingly popular, but feature different characteristics—display and input modalities, personal/public use, performance, and portability. In this paper, we first identify possible roles for both devices and the interplay between them throu...

Distributed Interactive Workspaces (DIWs) are interactive environments, accessible through different devices, where end users create new content by exploring and aggregating data retrieved from distributed resources in the Web, tailor this content to their own personal needs, use it on different devices, and possibly share and co-create it with others. The need for collaborating with other peop...
