This full paper in the innovative practice category introduces a uniquely novel visual privacy themed game, which is meant to be used as an experiential learning tool for teaching plus demonstration of fundamental data privacy concepts and basic security concepts. To our knowledge, this new, innovative visual privacy themed game, as presented in this paper, is the first of its kind gamified educational tool, which makes use of the privacy through visual anonymity i.e. VPET (Visual Privacy Enhancing Technology) theme for effective illustration of privacy concepts along with basic security concepts. This paper describes our nifty, visually interactive VPET game, which teaches privacy plus security concepts through the PET illustration and demonstrates applied cryptography for privacy-driven de-identification through obscuration-based disguise tasks during the game play. It also discusses how we have successfully used a pilot, proof of concept prototype version of this game over the last few years for cybersecurity education and outreach primarily at the K-12 level. Over the last few years, we have surveyed several VPET game players, who are from a large, diverse group of K-12 community members, consisting mainly of high school students and teachers, who have played the VPET game, as part of several cybersecurity training camps and outreach workshop sessions, and have benefited from this exercise in terms of learning, as well as developing awareness plus interest in privacy and security topics. This paper shares and analyze the preliminary data collected from all these survey responses to evaluate the prospects of our unique VPET game as a potential educational and outreach tool for engaging K-12 learners, for teaching privacy plus security concepts, and for creating awareness plus interest in cybersecurity. In summary, we demonstrate how our unique VPET gamification approach for educational purposes can successfully engage students for effective learning of data privacy and cybersecurity concepts.

Reusable ontologies are becoming increasingly important for tasks such as information integration, knowledge-level interoperation and knowledge-base development. We have developed a set of tools and services to support the process of achieving consensus on commonly shared ontologies by geographically distributed groups. These tools make use of the World Wide Web to enable wide access and provide users with the ability to publish, browse, create and edit ontologies stored on an ontology server . Users can quickly assemble a new ontology from a library of modules. We discuss how our system was constructed, how it exploits existing protocols and browsing tools, and our experience supporting hundreds of users. We describe applications using our tools to achieve consensus on ontologies and to integrate information. The Ontolingua Server may be accessed through the URL http://ontolingua.stanford.edu

Virtual documents are hypermedia documents that are generated on demand in response to reader input. This paper describes a virtual document application that generates natural language explanations about the structure and behavior of electromechanical systems. The application, called DME, structures the interaction with the reader as a question–answer dialog. Each page of the hyperdocument is the answer to a question, and each link on each page is a follow-up question that leads to another answer. DME is a model-based virtual document generator; unlike conventional database front-ends that provide views onto data, DME dynamically constructs the document's content (i.e. coherent explanations in English) from underlying mathematical and symbolic models. DME-based virtual documents have been running on the WWW since late 1993. They are used to document engineered systems in support of collaborative design and simulation-based training. In this paper we describe and demonstrate the DME application (with examples that run), and describe how it generates virtual documents on the web. We discuss the impact that model-based virtual documentation can have on the way technical documentation is authored and delivered.

We show how to deliver a sophisticated, yet intuitive, interactive application over the web using off-the-shelf web browsers as the interaction medium.This attracts a large user community, improves the rate of user acceptance, and avoids many of the pitfalls of software distribution.Web delivery imposes a novel set of constraints on user interface design.We outline the tradeoffs in this design space, motivate the choices necessary to deliver an application, and detail the lessons learned in the process.These issues are crucial because the growing popularity of the web guarantees that software delivery over the web will become ever more wide-spread.
