It is difficult to interact with computer displays that are across the room, which can be important in meetings and when controlling computerized devices. A popular approach is to use laser pointers tracked by a camera, but interaction techniques using laser pointers tend to be imprecise, error-prone, and slow. Therefore, we have developed a new interaction style, where the laser pointer (or ot...

As mobile devices have become more and more popular, we are seeing more location-based applications on handheld devices. Since the screen size of a handheld device is very limited, using a map on such kind of devices can be quite difficult. To make these applications easier to use, we want to use a situation model to provide user a better service. In this paper, we analyze user map operations a...

Emerging technologies such as location-awareness devices have the potential to significantly impact users’ social coordination, particularly while rendezvousing. It is important that we explore how new technologies influence social behaviours and communication in order to realize their full potential. This paper presents a field study investigating the use of mobile location-aware devices for r...

With the progress of the mobile communication technology and the popularity of the handheld devices, mobile commerce is of great importance today. We can use these devices to conduct business, such as to purchase books, and stocks, and digital goods (videos, audios, codes), and to play games, receive email, and even access various network resources. When the requested services need to be verifi...

Streaming multimedia content to heterogeneous handheld devices is a significant research challenge, due to the diverse computation capabilities and battery lifetimes of these devices. A unified framework that integrates low level architectural optimizations (CPU, memory), OS power-saving mechanisms (Dynamic Voltage Scaling) and adaptive middleware techniques (admission control, transcoding, net...

Employing mobile augmented reality (AR) to assist utility field personnel is a novel approach, which has become considerable in recent years with the advent of AR applications running on handheld computing devices. Unlike conventional solutions, AR provides a more intuitive interface to access complex underground utility network data in the field. As a result, common field tasks concerning main...

Traditional technology adoption models identified ‘ease of use’ and ‘usefulness’ as the dominating factors for technology adoption. However, recent studies in healthcare have established that these two factors are not always reliable on their own and other factors may influence technology adoption. To establish the identity of these additional factors, a mixed method approach was used and data ...

Bluetooth connectivity allows workers to access information anywhere, including both personal and corporate information. Software and applications have been specifically developed for handheld devices such as PDAs, giving users a high level of usability and functionality. The goal of this paper is to present an information security evaluation of a Bluetooth enabled handheld device, such as a PD...

Handheld and embedded devices are becoming increasingly popular and their uses are more versatile. Applications on these devices often need storing, retrieving and synchronizing data. IBM DB2 Everyplace is a high performance small footprint DBMS that is targeted in this market segment. In this paper, we will describe the overall architecture, features and several design consideration.
