This paper explores current applications for handheld devices and questions which of these make full use of the unique attributes of handheld devices in order to facilitate learning in a pedagogically sensible manner. In order to do so, the paper presents a functional framework which analyses handheld application in relation to their use as well as the pedagogical underpinning, if any, that inf...

Recently, handheld devices have become one of the most popular computing tools. Although handheld devices are able to perform anything that a PC can do, their lack of computing power makes it next to impossible to perform some heavy calculations. Hence it appears very useful to have a combination of a handheld with a PC, where the PC can perform heavy calculations to assist the handheld. Howeve...

In this study, the effects of using handheld devices on the performance of automatic signature verification systems are studied. The authors compare the discriminative power of global and local signature features between mobile devices and pen tablets, which are the prevalent acquisition device in the research literature. Individual feature discriminant ratios and feature selection techniques a...

The progress of handheld devices has encouraged many researchers to make efforts to use handheld devices as an augmented reality platform. However, one of the important problems is a lack of immersion and reality due to small display. To overcome this problem, we introduce dynamic environment which consists of some movable structures and their controller that enable changes of virtual world to ...

Handheld mobile devices are an exciting new platform for Augmented Reality (AR). Mobile phones and PDAs have the potential to provide AR experiences to hundreds of millions of consumers. However, before widespread use can occur there are some obstacles that must be overcome. In particular, developers must consider the hardware and software capabilities of mobile devices and how these can be use...

The field of mobile agents now plays an increasing role in modern information technology, especially in the light of advancing developments of handheld devices. In our CARLA project, we are developing an architecture for Java-based mobile agents to be used on small devices, which relies on CORBA as its basic communication infrastructure. To this end, the architecture falls back on the minimumCO...

Purpose – The purpose of this paper is to carry out a survey in order to better understand the nature of handheld mobile computing use by academic library users and to determine whether there is a significant demand for using the library services with these small screen devices. Design/methodology/approach – A survey is created to measure whether people want to access an OPAC with a small scree...

This paper presents the design and implementation of a Grid-enabled physics analysis environment for handheld and other resource-limited computing devices as one example of the use of mobile devices in eScience. Handheld devices offer great potential because they provide ubiquitous access to data and round-the-clock connectivity over wireless links. Our solution aims to provide users of handhel...

BACKGROUND Computing technology has the potential to improve health care management but is often underutilized. Handheld computers are versatile and relatively inexpensive, bringing the benefits of computers to the bedside. We evaluated the role of this technology for managing patient data and accessing medical reference information, in an academic intensive-care unit (ICU). METHODS Palm III ...

PURPOSE: A new category of handheld devices has recently emerged that are even smaller than current portable models, with their main advantages being increased portability and affordability relative to their counterparts. However, these new devices have not yet been thoroughly evaluated in the clinical setting. METHODS: A prospective, non-blinded, three-phase study was designed to evaluate a ha...
