Today the user of personal computers is facing several inconsistencies which originate from an unresolved situation between two competing interaction models. The WIMP desktop model was developed nearly 30 years ago at Xerox Parc and Apple Computer. The web model became popular in the mid 1990s and has profoundly changed business and the perception of social relationships. Contradictions between...

The academic world is at the beginning of a major shift in the library computing paradigm. Librarians have participated in the movement from paper-based systems to mainframe computing. This was followed by the movement to personal computing based on ever more sophisticated and powerful personal computers. In the past few years we have begun to see the development of the use of portable laptop c...

MIT App Inventor is a drag-and-drop visual programming tool for designing and building fully functional mobile apps for Android. App Inventor promotes a new era of personal mobile computing in which people are empowered to design, create, and use personally meaningful mobile technology solutions for their daily lives, in endlessly unique situations. App Inventor’s intuitive programming metaphor...

Over two decades of research in the field of Interaction Design and Computer Supported Cooperative Work convinced us that the current design of workstations no longer fits users’ needs. It is time to design new personal computers based on metaphors alternative to the desktop one. With this SIG, we are seeking to involve international HCI professionals into the challenges of designing products t...

Universal Personal Computing (UPC) is a novel concept to support nomadic computing on the Internet. UPC enables mobile users to access their personalized computing environment anywhere on the Internet using any available terminals. The system is modeled as distributed objects using CORBA to facilitate their distribution, interfacing, and integration. We have chosen SDL for our system design. Th...

Protection of personal data in the Internet is already a challenge today. Users have to actively look up privacy policies of websites and decide whether they can live with the terms of use. Once discovered, they are forced to make a ”‘take or leave”’ decision. In future living and working environments, where sensors and context-aware services are pervasive, this becomes an even greater challeng...

This paper proposes a new of cloud computing for individual computer users to share applications in distributed communities, called community-based personal cloud computing (CPCC). The paper also presents a prototype design and implementation of CPCC. The users of CPCC are able to share their computing applications with other users of the community. Any member of the community is able to execut...

ion provided by TCP. Although this yielded a simple implementation, it caused TCP-related resources to be exceeded on occasion, thereby denying service to new clients. Our decision to embed the file location database in stub directories in the VICE naming tree made it difficult to move users’ directories between servers. Finally, Venus based its cache replacement algorithm on the total number o...
