A US company has developed a new technology that would drastically reduce power usage by mobile devices' displays. The iMoD (interferometric modulator) approach would enable cellular phones, MP3 players, and other battery-operated, power-constrained devices to run all day in many cases. iMoD uses optical interference to display images. Pixels in an iMoD display consist of a flexible thin-film mirror...
Just as cell phones will soon deliver TV programming and analog TVs will disappear, the PS3 represents another mutation in the evolution of entertainment: game consoles transformed into media centers. Whatever form they might take in 2009, these entertainment systems will be in a world strangely different from 1967, when consoles, the Internet, Wi-Fi, smart cards, DVDs, digital video recorders, MP3...
As if it were a comet we have been speculating about and tracking over the past two years, the iPhone is no surprise, but we still can't keep our eyes off it. Like the Apple II, the iPhone will arrive with an impact that affects several domains - financial, technical, and cultural. Although felt immediately, understanding its full impact will take years. Strategically, the iPhone will help Apple protect...
The mobile phone has evolved from a basic device that just makes calls to a multifunctional gadget like the iPhone, which can also retrieve e-mail, store and play music, surf the Web, and stream video files. This reflects the advance in mobile technology from the 1980s' first-generation (1G) circuit-switched analog systems to today's 3G and even 3.5G digital technologies. The International Telecommunication...
A Swiss e-voting system, operational since December 2004, is based on a service-oriented architecture that lets voters use Internet or mobile phones to cast votes. Two-step encryption and redundant storage systems keep votes authentic and confidential.
UbiFit uses on-body sensing, real-time activity inference, and a personal, mobile display to encourage people to incorporate regular and varied physical activity into everyday life.
The widespread deployment of technologies like mobile phones continues to drive new applications and to open research opportunities. This article talks about ubiquitous computing and how people understand and interact with computing. Pervasive computing technologies are transparent to users until the system malfunctions. Minor breakdowns are common, and people get used to them. However, when breakdowns...
Commodity hardware enables a range of cost-effective ubiquitous computing research, but innovative custom hardware can drive compelling new user experiences. One of the dreams of ubiquitous computing is an ecology of heterogeneous computer systems, built into the environment around us and acting in concert to make our lives easier and more fun. Fundamental to this vision is a movement away from the...
Topics include a prototype system that turns a user's arm or hand into a keyboard or display screen, a device that could enable high-speed wireless communications in place of many of the wired transmissions currently used in homes and offices, a cyberextortion scheme that targets people who download pornography, and a visualization toolkit for discovering geographic trends that could help fight diseases.
Because vendors see a profitable opportunity in applications that let users pay for goods and services via mobile devices, they are releasing easier-to-use mobile-payment applications.
Is the increasing number of mobile devices advertised as 4G a product of marketing hype, or does it represent the traditionally assumed one-order-of magnitude improvement over the previous generation of cellular architectures?
Despite many significant challenges, ARM chip developers are pushing ahead with plans to go beyond mobile devices and enter the laptop, desktop, and server markets.
Platforms, runtimes, and middleware play a vital role in an evolving mobile computing environment in which the trend is toward converged communication, where Web resources integrate seamlessly with mobile systems.
The development of entirely new types of Web-based software systems built to leverage the vast capabilities of the World Wide Web allows the use of dynamically downloaded applications and services from any type of terminal, including both desktop computers and mobile devices, implying radical changes in the ways people develop, deploy, and use software.
The Terminal Mode technology integrates smartphones into in-vehicle infotainment systems and transforms them into automotive application platforms on the fly, allowing drivers to safely access and interact with mobile applications.
Researchers are exploring the rendezvous concept - bringing sensors close to one another in space or time - as a way to make sense of disparate data collected by individuals. Applications such as participatory atmospheric sensing illustrate the potential of rendezvous to help create powerful mobile applications.
The growing popularity of wireless technology may have finally attracted enough hackers to make the potential for serious security threats a reality. The world of computers and communications, the more widely a technology is used, the more likely it is to become the target of hackers. Such is the case with mobile technology, particularly smartphones, which have exploded in popularity in recent years...
