User and device diversities are two main factors combating efficient information communication in a mobile or pervasive computing environment. Additionally, the derivatives of traditional desktop computer such as handheld and wearable devices suffer from constrained resources. Most of these devices are faced with small display sizes, small computing power and storage capability. Likewise, end users...
This paper conveys some of the experiences with using commercial off-the-shel (COTS) products as clients to Bluetooth enabled devices, which have no user interface of their own, but relies on the COTS products for user interaction. The COTS devices used include several different vendors' models of the microsoft Pocket PC platform (also known as windows mobile professional or classic) running .NET...
In a dynamic heterogeneous environment, such as pervasive computing, context-aware adaptation is a key concept to meet the varying requirements of different clients. However, this newfound versatility poses difficult challenges for user-interface design. The traditional UI development measures seem insufficient toward this situation. As the concept of design pattern in architecture and software engineering,...
The emerging paradigm of pervasive computing and Web services needs a flexible service discovery and composition infrastructure. The widespread use of Web services in pervasive environments is hindered by the lack of adequate security and privacy support. In this paper, we discuss an access control protocol for conversation-based (composite) Web services. This approach takes into account the conversational...
Experimental test is a necessary part of human engineering oriented design. Besides testing results obtained from testing equipments, experience from test participants is also essential. Therefore, participants' ability of communication and expression is highly demanding. But it's difficult to achieve in some given testing environment. That's how building an experimental intelligent testing environment...
Summary form only given. "The most profound technologies are those that disappear. They weave themselves into the fabric of everyday life until they are indistinguishable from it." Seldom has an era begun equally decidedly as the age of Pervasive Computing with these famous words from Mark Weiser has in 1991. However, while computers have almost shrunk to disappearance in the meantime, user...
In this paper, we present a framework of modeling concept sketch and sketching interaction based on context-awareness. And an operational model for sketching interface has been developed. This new model can guide and help new sketch-based interface development. From a software engineering point of view, the operational model can be implemented as a basic class with a set of standard operational functions...
