Using handheld devices in educational environments is thought valuable because handheld devices have the advantage of their cheapness, mobility, enough capability and so on. And changing national curriculum standards for kindergartens in Japan, teachers have to give children oppotunities where they integrate their knowledge and apply to some problems. So a new system which provides new learning...

The Project54 system allows the integration of electronic devices in police cruisers. Both the software and the hardware system architecture are modular. The software is composed of components running on an embedded computer and distributed components deployed on a handheld computer. The hardware architecture utilizes an in-car serial bus to connect various in-car electronic devices and a wirel...

One of the emerging technologies is wireless handheld technology and implication of these devices is enormous for business community, healthcare domain is not an exception to this phenomena. This research paper provides some useful finding about the use of PDA’s in the healthcare environment through actual usage of PDA in the healthcare ward. A qualitative and quantitative approach was adopted ...

User authentication is a difficulty for every system providing safe access to precious, private information, or personalized services. It is a continual problem, particularly with mobile and handheld devices such as Personal Digital Assistants (PDAs). User authentication is the primary line of defence for a handheld device that comes into the hands of an unauthorized individual. Password or Per...

Handheld devices have limited processing power and a short battery lifetime. As a result, computational intensive applications can not run appropriately or cause the device to run out-of-battery too early. Additionally, Internet-based service providers targeting these mobile devices lack information to estimate the remaining battery autonomy and have no view on the availability of idle resource...

Adequate user authentication is a persistent problem, particularly with handheld devices such as Personal Digital Assistants (PDAs), which tend to be highly personal and at the fringes of an organization's influence. Yet, these devices are being used increasingly in corporate settings where they pose a security risk, not only by containing sensitive information, but also by providing the means ...

This paper proposes iMail, a WAP mail retrieving system designed for wireless handheld devices to access Internet email service. In mobile data networks, the communication bandwidth is limited and the wireless handsets are constrained by small display, powerless CPU, limited memory, and unhandy input/output interface. To support mail retrieving in a mobile environment, we implement several feat...

The main drawbacks of handheld devices (small storage space, small size of the display screen, discontinuance of the connection to the WLAN, etc.) are often incompatible with the need of querying and browsing information extracted from the enormous amount of data which are accessible through the network. In this application scenario, the issues of compression and summarization of data have a le...

We propose a new haptic interface for handheld devices using the “estimation of box contents” metaphor. This metaphor refers to a situation in which a person shakes a box to determine what is contained in it. In this interface, a handheld device is compared to a box, and the information contained in the device is compared to an object contained in the box. The user can determine if information ...
