32.1 Introduction use none none printer toinsert none on none Java Reporting Library-Jasper Reports As high-perf none for none ormance computing in small form factor devices arrives, a shift from traditional browser-based interfaces to a combination with full self-contained services has become increasingly evident. These same mobile devices are standardized and inexpensive, creating whole new opportunities to cost-effectively computerize groups of mobile workers. These services offer superior interactivity, work both online and offline and utilize the onboard processing power to execute locally, saving both bandwidth and precious battery life.

To support these services, new powerful distribution mechanisms are needed to allow for automatic installation, filtering and execution over wireless networks - a service profiling and provisioning scheme that makes discovery, download and installation as natural as sending an email. These distribution mechanisms need to take into account several dimensions of the user s context (i.e.

, the information that describes the situation of a person or entity such as its location, time, profile, available bandwidth, language, and device type), when determining which services, data or content a user requires. This new mobile environment has to enable the mobile user with capabilities to complete work actively and provide background updates when the mobile user is on the move, thus providing mobile users with the best tools needed for their current task. To cater to these needs we present a context-aware service platform (call Appear IQ from Appear) for wireless networks.

It features two powerful tools for the mobile user; the patented Click & Run technology, enabling enterprises to distribute a combination of full applications, content and services over-the-air to smartphones, PDAs, laptops, tablet PCs,. Appear 672 Building the Mobile Computing Environment and UMPC (Ul tra Mobile PCs) in a single click; and the Appear Synchronization module, which always keeps the services up to date, whenever the mobile device is in network coverage.. 32.2 Trends As wireless users demand more and more data services in their handheld devices, the role of the device and the requirements on the hardware, undergo profound changes. The PDAs and smartphones launched today are not simply phones or electronic organizers, but powerful handheld computers with potent processors, a lot of memory and complete service environments. Service developers will benefit immensely from the open interfaces, high level of modularity and extensibility of the new handheld computers.

Regardless of which operating system they are targeting, services can be offered across multiple standards and devices globally. The major benefit and direct consequence of this for end-users, is that a flood of services will be made available for handheld devices, i.e.

both legacy and new mobile applications. As wireless devices become increasingly powerful more users will access services and the Internet using handhelds. Thus it is necessary to consider how this fundamental change - impacts the ideal usage model.

By analyzing the way user behavior changes from one type of use to the other, the following patterns have been identified: 32.2.1 Maximizing employee process efficiency and time savings The objective in a mobile work environment is for each employee to be served the necessary and relevant information to perform their work.

This maximizes the efficiency of the employee and effectiveness of customer interactions. To be efficient this has to be based on a system that anticipates the particular employees work requirements. A context aware solution solves this problem.

32.2.2 Mobile users behave fundamentally different from Desktop users Wireless users react to tasks, but are NOT proactive.

Wireless users are reactive and respond to a message or discover some issue that needs to be resolved. Automatic push mechanisms are necessary. Desktop users have the luxury of being able to select information to work on.

Wireless users focus on the work task or customer, NOT the computer. Wireless users tend to use their devices more as a tool while focusing on some completely different task, e.g.

fixing the escalator. Access to services must be as simple as possible. Desktop users are generally centered on the actual device (computer), e.

g. preparing an electronic spreadsheet. Wireless users need to be served the right information, they need the tool to anticipate their requirements, NOT surfing and searching.

Mobile workers are confronted with the situation of fixing a specific problem such as the wing of a plane or answering a.
