Use of object-oriented middleware will ease the development of distributed applications in pervasive and mobile computing environments. However, the handheld devices have limited resources and the wireless networks have limited capacity. In this paper, we evaluate if PDAs and laptops are powerful enough to run commodity CORBA implementations. We have performed and analysed thorough measurements...

Advances in computing hardware, communications technologies, and novel multimedia applications are spurring the development of smart phones and personal digital assistants. There is world-wide accessibility to 2G, 3G, and WiFi networks. Some examples of well-known wireless handheld devices are BlackBerry, iPhone, iPad, iPod, and Kindle. On the one hand, small size and light weight are their att...

Presently, there is an increasing demand of accessing Web from mobile handheld devices. However, due to the small screen of handheld devices, mobile users often suffer from the poor presentation that seriously hinders the usability of mobile applications. In addition, users have different information needs and preferences. They prefer to receive content of their interests in a preferred format....

The recent development of software platforms for cell phones and handheld computers, such as Java 2 Micro Edition (J2ME), has broadened application perspectives in this area. In fact, the developers can now write their own software to run in handheld devices, what was impossible a short time ago since the software and the platforms were proprietary. Among the myriad of applications for these de...

This descriptive study replicates and extends previous research on advanced practice RNs and the (1) reference resources available to them at the point of care, (2) resources they use to inform their clinical practice, and (3) resources they are accessing from handheld electronic devices such as PDAs, smartphones, and tablet computers during practice. These elements formed the purpose of the cu...

In this paper we describe the material of a construction kit designed to allow children to build their own handheld and wearable devices to meet their interests and passions. Children don’t work with these machines, they learn, play and grow with them. Informed by the types of projects that children have done with this material in the context of educational research in science and engineering, ...

The Musicology project explores how personal mobile devices, such a users’ cell-phones, can be used as conduits for bringing musical expression into public places such as cafés and coffee shops. This capability represents advanced usage models for emerging handheld devices, enabling personal music to be a more social experience by allowing people to easily play their music for others around the...

Everyday appliances, including telephones, ovens, and home stereos, increasingly contain embedded computers to provide greater functionality. Unfortunately, as these appliances become more complex, their interfaces are becoming harder to use. At the same time, more people than ever are carrying computerized devices that can communicate, such as cellular telephones, personal digital assistants, ...

Handheld Augmented Reality (AR) running on self-contained handheld computers and smartphones, can leverage an extremely large potential user base of existing devices and users knowing how to operate them. In this paper we report on a platform for collaborative handheld AR applications, which employs specific efficient techniques from embedded development to push the limits of AR applications in...

A number of studies have evidenced that handheld devices are appropriate tools to facilitate face-to-face collaborative learning effectively because of the possibility of ample social interactions. Group Area Network, or GroupNet, proposed in this paper, uses handheld devices to fill the gap between Local Area Network and Body Area Network. GroupNet is an independent network where all members a...
