We have developed and deployed a Web-based wireless classroom interaction system in a large-enrollment introductory physics lecture class that uses HP handheld computers (PDAs) to facilitate real-time two-way student interaction with the instructor. Our system is ahead of other “clicker” based systems that are primarily limited to multiple-choice responses. Our system allows for a variety of qu...

Although online, handheld, mobile computers offer new possibilities in searching and retrieving information on the go, the fast-paced, “sit -forward” style of interaction may not be appropriate for all user search needs. In this paper, we explore how a handheld computer can be used to enable interactive search experiences that vary in pace from fast and immediate through to reflective and delay...

This article describes techniques and strategies used to judge the potential applicability of new information management technologies in the clinical setting and to develop specific design recommendations for new features and services. We focus on a project carried out to identify the potential uses of handheld computers (i.e., the Palm Pilot or a small WinCE-based device) in the ambulatory pra...

OBJECTIVE To evaluate: (1) the effectiveness of wireless handheld computers for online information retrieval in clinical settings; (2) the role of MEDLINE in answering clinical questions raised at the point of care. DESIGN A prospective single-cohort study: accompanying medical teams on teaching rounds, five internal medicine residents used and evaluated MD on Tap, an application for handheld...

Handheld computers are commonly used in clinical practice and often considered invaluable by physicians. Though full of promise, the technology is still costly and literature assessing its real use in clinical practice remains scarce. In an effort to better understand how Personal Digital Assistants (PDA) can be utilized as clinical tools, we designed a study that closely monitored the use of a...

Given the growing use of mobile devices, there is now increasing interest in the potential for supporting the mobile learner. However, there remains much research to be undertaken, to Wnd eVective ways of facilitating learning with mobile devices. This paper considers how to support the mobile language learner using a handheld computer. It introduces TenseITS, a language learning environment th...

networked handheld devices to enhance school learning. In Abstract Handheld devices, especially networked handheld devices, are growing in importance in education, largely because their affordability and accessibility create an opportunity for educators to transition from occasional, supplemental use of computers, to frequent and integral use of portable computational technology. Why and how mi...

Handheld appliances such as PDAs, organisers or electronic pens are currently very popular. Handhelds are used to enter and retrieve useful information, e.g., dates, to do lists, memos and addresses. They are viewed as standalone devices and are usually not connected to other handhelds, thus sharing data between two handhelds is very difficult. Rudimentary infrastructures to exchange data betwe...
