ABSTRACT

Recent improvement in wireless technologies and infrastructures has conceived the demand for ubiquitous access to enterprise services from wireless handheld devices. Further, with the creation of new interaction apparatus, the context in which the services are being utilised becomes an integral part of the undertaking conveyed out with the system. Traditional human-computer interface (HCI) ideas are now insufficient for evolving these context-aware submissions, as we accept as factual that the idea of context should be expanded to distinct categories: computing contexts, client contexts, and personal contexts for ubiquitous computing. This claims a new paradigm for scheme obligations elicitation and conceive in alignment to make good use of such expanded context data apprehended from wireless client behavior. Instead of redesigning or acclimatizing living enterprise services in an ad-hoc manner,

Introduction

The advancement and prevalent use of wireless technologies has conceived an expanding demand for the elongation of enterprise services to anytime and any location access. Although the computing power and bandwidth of these wireless apparatus are advancing, their capabilities are still considerably inferior to desktop computers over the connected Internet. As most living e-services are not conceived to support users on wireless stages, they have to be acclimatized to accommodate these limitations.

With the prevalent use of wireless apparatus and the require for ubiquitous computing, the topic of “context” now becomes a warm theme in human computer interaction (HCI) study and development. There are some causes why context is significant (Weiser, 1991). First, context decreases the input cost. Explicit input from users is expensive. It cuts off the user's ideas and slows down down the pace of the interaction. Analyzing users' demeanour, for example feeling the natural environment and understanding explicit activities through wireless apparatus, could supply a wealthy and implicit context.

Context makes the connection between humans and computing apparatus much more efficient. Second, context may provide an stimulating client know-how without much effort on the users' part. With the assist of context, interactive services such as tourist direct support, note reminder service, and intelligent home are accessories that can make people's inhabits easier. Third, users advantage from context sharing. We may suppose that users and their associates have alike preferences, which entails certain thing that attracts one assembly member's vigilance has a higher likelihood of being favoured by other members. By distributing the context, the scheme could supply a better service.

However, going the interaction after the desktop presents numerous ...
