Collaborative learning is widely used in classroom activities. The screens of handheld devices, designed for individual-user mobile application, which may constrain the interactions among group learners. The small size of screen may lead to fragmented and tête-à-tête communication pattern, and frequently obstacle the externalization of student learning process. This study proposes a shared disp...

This project that deals with the proxy gateway and unicast client of the larger Scalable Video Delivery project. The aim of the project is to deliver video to heterogeneous clients using only one video stream. This possible using a layered multi-wavelet codec that allows a video stream to be encoded, divided and distributed using multicast. A multicast method of delivery would mean that the cli...

The current trend is towards having Java applications run on handheld mobile devices. Sun Microsystems, Inc. has addressed this trend by specifying an edition, namely Java 2 Micro Edition (J2ME), of the Java environment for handheld devices. J2ME divides into two configurations: Connection Limited Device Configuration (CLCD) and Connected Device Configuration (CDC). This paper focuses on the la...

Mobile phones have become ubiquitous in today’s society. However, mobile users are no longer satisfied with simple phones but instead expect ever more powerful functions to be available from their mobile devices. Advanced phones known as smartphones allow mobile users to perform a wide variety of advanced handheld functions such as browsing the mobile Internet or finding a nearby theater showin...

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...

We discuss design principles for a handheld haptic device, scenarios for their use, and our implementation of a portable handheld haptic device following these principles. Handheld devices offer unique challenges and opportunities for haptics: they are compact, simple and consequently low cost, while promising comfort, low fatigue, and affordances for many useful tasks such as controlling digit...

An emerging research direction in the field of pervasive computing is to voice-enable applications on handheld computers. Map-based applications can benefit the most from multimodal interfaces based on speech and pen input and graphics and speech output. However, implementing automatic speech recognition and speech synthesis on handheld computers is constrained by the relatively low computation...

In fact, video compression techniques like MPEG-4 and others are reducing the wireless bandwidth needed for streaming video. But there still remain other factors, which are just as critical as bandwidth, if not more so. Beyond bandwidth, the other half of the streaming video equation is the architecture and capabilities of the terminal device itself. Even if unlimited wireless bandwidth were su...

We present the final MIAMM system, a multimodal dialogue system that employs speech, haptic interaction and novel techniques of information visualization to allow a natural and fast access to large multimedia databases on small handheld devices.

Handheld computing has had many applications in medicine, but relatively few in pathology. Most reported uses of handhelds in pathology have been limited to experimental endeavors in telemedicine or education. With recent advances in handheld hardware and software, along with concurrent advances in whole-slide imaging (WSI), new opportunities and challenges have presented themselves. This revie...
