Designing a Shared Single Display Education Application through Interactive Patterns

Abstract

Interactive patterns are able to promote the notion of reusability in groupware application development. Hence, these patterns support the comprehensiveness of both the interaction design and implementation while easing code modification for groupware application. Groupware is used to describe a broad range of technologies that support person-to-person collaboration. How to design and develop a groupware in an effective manner remains a research question worth exploring. This paper introduces a reusable method, patterns, to develop a single shared display application. Nine different interactive patterns that allow participants to interact collaboratively or noncollaboratively in a single shared display application are introduced in this paper. This is followed by the presentation of our quantitative results on the usability of the interactive patterns and the reusability of the patterns in designing and maintaining a single shared display application. From the results, not only are the patterns useful and easy to understand, the patterns actually ease the process of designing and maintenance during the application development under a single shared display. KeywordsCollaborative Learning, Interaction Design, Shared Single Display W. S. Cheah et al. 1075 While various SDG applications have been developed [2]-[4], we argue that the development of SDG is still a trivial job. Neither the applications disclose the details design nor the activities behind the interaction. Hence, how to develop a SDG that is engaging, communicative, coordinating and interactivity is still a challenge. We are taking a reusable approach in dealing with this development. Our motivation is to reuse the recurring problem and solution in rapidly developing a SDG application.We introduce a reusable method, patterns, to develop a single shared display application. Patterns are defined according to a generic template form. This template form is also known as a problem-frame in the literature [5]. The template is generally expressed by means of the pattern elements like name, intent, applicability, problem, force, solution, example, implementation, consequence and related patterns.Nine different interactive patterns that allow participants to interact collaboratively or non-collaboratively in a single shared display application are introduced in this paper. This is followed by the presentation of our quantitative results on the usability of the interactive patterns and the reusability of the patterns in designing and maintaining a single shared display application. From the results, not only are the patterns useful and easy to understand, the patterns actually ease the process of designing and maintenance during the application development under a single shared display.Patterns for general development of collaborative applications are proposed in [6]. When developing collaborative application, we should consider the design aspect of group memory, handle the collaborators information (e.g. access rights to the information), handle the floor of i...

Agent Oriented Methodology for Crime Modelling and Simulation

“…Agent Oriented Methodology [1]- [3] provides a way to represent a complex system of autonomous agents or actors and simulates the multiple potential results of these agents' behaviors and interactions between the desired agents. To date, it has been used in rural ICT study, disaster management, military training, collaborative learning [7], sustainability study [4], mathematical science and simulation [8]- [10], security [5], games [6]. An agent-oriented model is usually comprised of virtual "agents" who owns unique behavior and able to act autonomously without a central controller.…”

Developing Agent-Oriented Video Surveillance System through Agent-Oriented Methodology (AOM)

“…Until recently, the agent technology has been adopted in a range of areas including collaborative learning games [4], rural ICT [5], ubiquitous computing, e-commerce (business to business-B2B and business to client-B2C) [6], robotic [7], library [8], e-learning, manufacturing, logistic [9], environment, banking [10], construction [11], bioinformatics, accident management [12], power management [3], crisis management [13], sustainable software [14], mathematical model [15] and grid computing. For example, the agent technology is used to support the collaborative design environment among the project's participants in the construction application.…”

Agent-Oriented Requirement Engineering for Mobile Application Development

“…As a result, there is a need to introduce a new mechanism or methods in order to support the complex system development for mobile application. Inline with the works to explore agent models for software application [12,13,14,15,16], this paper introduce agent-oriented requirement engineering for mobile application development.…”
