Present handheld devices like Smart phones, can be charged wirelessly using new energy harvesting circuit technique through using the traditional wireless technologies. In this case, Bluetooth with a charging circuit enables a short-range wireless charging of a mobile handheld. This paper present the overview of new process of charging and structure of power charging based on Scotty diode with ...

This paper focuses on the design of devices for handheld spatial interaction. In particular, it addresses the requirements and construction of a new platform for interactive AR, described from an ergonomics stance, prioritizing human factors of spatial interaction. The result is a multi-configurable platform for spatial interaction, evaluated in two AR application scenarios. The user tests vali...

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...

Usability is one of the characteristics that compose the multi-dimension concept of information systems' quality. Technology improvements enable the building of information systems to be used "any place, any time", through mobile handheld devices and wireless networks. Usability is threatened by the use of mobile-wireless information systems, especially because of the use of small devices with ...

The introduction of portable, pocket-sized echocardiography devices in various healthcare systems has raised new questions with regards to their realistic use in clinical practice. Several studies have already attempted to provide information regarding their safety and diagnostic potential, the training required to operate them, as well as their direct comparison with standard echocardiography ...

This paper describes the development of an embedded Cantonese text-to-speech synthesizer to enable multi-device access to Chinese Web content. Advancements in wireless communication is driving Web visitors from using desktop PCs to mobile handheld devices. Significant reduction in the form factors of the client devices tends to shift information delivery from the visual to the aural modality. T...

The proliferation of mobile handheld devices, such as Personal Digital Assistants (PDAs) and tablet computers, within the workplace is expanding rapidly. While providing productivity benefits, the ability of these devices to store and transmit corporate information through both wired and wireless networks poses potential risks to an organization’s security. This paper describes an approach to a...

Context-aware devices, which detect the use context in order to adapt the device behavior in appropriate means, provide challenging design tasks in the field of humancomputer interaction. Especially, mobile handheld devices form a potential group for context-aware applications, since they are used in various different kind of situations, and the prioritized applications and interaction styles c...
