Mobile handheld devices have stringent constraints on power consumption because they run on batteries that have a limited lifetime. Conserving power to prolong battery life is of primary importance for these devices. Several factors such as backlight intensity, the hard disk, the CPU, the network interface and the nature of the application contribute significantly towards power consumption for ...

More and more devices are equipped with global positioning system (GPS). However, those handheld devices with consumer-grade GPS receivers usually have low accuracy in positioning. A position correction algorithm is therefore useful in this case. In this paper, we proposed an evolutionary computation based technique to generate a correction function by two GPS receivers and a known reference lo...

With the increasing adoption of handheld computers and their integration in our daily life, mobile computing is becoming an important component of existing computing environments. The new forms of interaction made possible by mobile computing pose new challenges for the design of pervasive computing environments aimed at seamlessly integrating heterogeneous devices. Among these devices, handhel...

The rapid development of technology in Internet and wireless communication makes it possible for people to access multimedia contents and services using handheld devices. However, most multimedia contents and services in the Web are optimized for desktop computing environment. They contain rich media data, which are not suitable for handheld devices with limited capabilities and resources. More...

The key limitation of handheld technology for the delivery of learning objects is the small screen that is available for effective display. The smallness of the screen not only adversely affects the clarity, but it also negatively impacts on the acceptance and integration of this potentially useful technology in education. Handheld devices are likely to change further in size in the future with...

Streaming multimedia content to heterogeneous handheld devices in an real environment, under power, bandwidth and load constraints is a significant design challenge, due to the various capabilities of these devices and the real-time character of the streaming workloads. A unified framework that integrates low level architectural optimizations, OS power-saving mechanisms and adaptive middleware ...

In recent years the demand for low power devices has increased tremendously due to the migration of computer workstations to handheld devices that need real-time performance within the budget for physical size and energy dissipation. As a result of this there is a fast growth of battery operated portable applications such as PDAs, cell phones, laptops and other handheld devices. But also at the...

[Abstract] Wireless access with handheld devices is a promising addition to the WWW and traditional electronic business. Handheld devices provide convenience, portable access, and large amounts of information to travelers. Tourism presents considerable potential for the use of new mobile technologies; however, limited research exists on mobile users’ perspectives with regard to satisfaction tow...

Due to the dramatic technology development in Internet and wireless communication, it becomes possible to access multimedia contents and services using handheld devices. However, most multimedia contents and services on the Web are optimized for desktop computing environment. Even though multimedia contents can represent rich semantics, they are not suitable for handheld devices with limited re...
