Cellphones could be used to build 'audio internet'

, , , ...

ON A cold winter's day in December 2006, Guruduth Banavar's team gathered up some workers at a bustling marketplace in New Delhi, India, and cajoled them, each in turn, into a car.

The team was from the IBM India Research Laboratory (IRL) in New Dehli. They had come to the market to test an alternative to the internet for India's rural population. The system is based on the cellphone, though, and so the din of hawkers selling vegetables, and shoppers looking for everything from jewellery to electronics, made conversation impossible.

Once inside the car, however, 10 of the 12 volunteers - who had never before interacted with a speaking computer - were able to create their own voice-based website, or VoiceSite, in just under 4 minutes apiece. The first trial of the "spoken web" was a success.

Virtual touchpad lets you scroll in thin air

, , ,

The Apple iPhone's sexy touchscreen with its multi-touch commands has been a huge hit with the public, but such screens can only get so small before clunky fingers get in the way. So Microsoft is extending the concept of the touchscreen beyond the edges of the phone itself.

The company's researchers have developed a system called SideSight, which allows you to control a phone placed on a table by wiggling your fingers in the space around it. The technology was unveiled last week at the User Interface in Software and Technology symposium in Monterey, California.

Alex Butler of the Sensors and Devices Group at Microsoft Research Cambridge in the UK lined the long sides of a phone with infrared sensors that can pick up the movement of fingers up to 10 centimetres away.

"The big advantage of our prototype is the finger does not block any of the screen space," says Butler.

Android to officially debut on HTC Dream next week

, ,

Google's Android will be unveiled to the world on its first officially-supported device, the HTC Dream, on September 23. T-Mobile, third-largest mobile carrier in the US and Google's launch partner, sent out invites Tuesday to next week's press conference in New York. T-Mobile plans to demo the device and OS to reporters then and there, although the Android-enabled Dream isn't expected to land in stores until October.

Google and T-Mobile began cozying up around April of this year as the carrier became the first to plan an Android launch, scheduled for the second half of 2008. Since then, rumors cropped up about a possible Android delay, with various handset manufacturers and carriers complaining of holdups in development that could push them into 2009. However, buzz about the launch started up again last month when insiders who were briefed on T-Mobile's plans said that all three companies—Google, HTC, and T-Mobile—planned to announce the device in September.

Electronic tattoo display runs on blood

, , , ...

Jim Mielke's wireless blood-fueled display is a true merging of technology and body art. At the recent Greener Gadgets Design Competition, the engineer demonstrated a subcutaneously implanted touch-screen that operates as a cell phone display, with the potential for 3G video calls that are visible just underneath the skin.

The basis of the 2x4-inch "Digital Tattoo Interface" is a Bluetooth device made of thin, flexible silicon and silicone. It´s inserted through a small incision as a tightly rolled tube, and then it unfurls beneath the skin to align between skin and muscle. Through the same incision, two small tubes on the device are attached to an artery and a vein to allow the blood to flow to a coin-sized blood fuel cell that converts glucose and oxygen to electricity. After blood flows in from the artery to the fuel cell, it flows out again through the vein.

Point and Click on Buildings: The World Becomes the Web

, , ,

You stand in front of a hotel. You point your cell phone at it. You click. The hotel's Web page appears on the device's screen. You check accommodations, prices, vacancies and inquire about special offers. Then you walk in or walk on.

That's right — the world will turn into the Web and clicking an icon on the screen of a desk-tethered PC will be passé. Clicking will become a matter of interacting with the environment, thanks to the advent of "location-based services" (LBS).

It's already a reality in Japan through the KDDI network there, using software from GeoVector Corp. in San Francisco. Pamela Kerwin, GeoVector's vice president of strategic development, explained that LBS requires that the phone has GPS circuitry, so it knows where it is. Additionally, it needs to have a compass so it knows where it is pointed.

World’s first TD-SCDMA HSDPA/GSM multi-mode mobile phone

, , ,

Samsung, NXP Semiconductors and T3G Technologies, today (November 9 2007) announced the world's first TD-SCDMA HSDPA/GSM/GPRS/EDGE multi-mode mobile phone, which has also been demoed at the PT/Wireless Exposition in Beijing on October 23rd.

Powered by a software-defined modem capable of achieving data transfer rates of 2.8Mbps, the Samsung SGH-T578H enables about 20 times faster transfers than GPRS, allowing consumers to download several high-quality MP3 files in less than a minute. The phone is based on the T3G7210 system solution featuring the industry's first soft modem empowered by NXP's Embedded Vector Processor (EVP) to achieve high data transfer and multi-mode capability.

TD-SCDMA network deployments have been completed in 10 major cities across China where there are more than 70 million potential subscribers. This network is planned to be upgraded to support Release 5 (HSDPA) of the TD-SCDMA standard during the course of 2008. With the Samsung SGH-T578H mobile phone, users will be able to enjoy the widespread deployment of TD-SCDMA infrastructure to support high-speed streaming of multimedia coverage of the Beijing Olympics 2008.

A reconfigurable handheld device could foster a community of hardware hackers.

, , ,

Software has become easier to customize in the past decade, but hardware, for the most part, remains closed: Apple's battle to keep people from hacking the iPhone is a case in point. Although most consumer electronics are collections of smaller devices--cell phones typically include cameras and voice recorders, for example--users can't swap out the devices or modify the way they work. Bug Labs, a startup based in New York City, is hoping to change that with its new device, the Bug, scheduled to start shipping late this year.

The Bug would allow users to design their own electronics and customize them however they want. CEO Peter Semmelhack explains that the foundation of the device is the Bugbase, a minicomputer running Linux that users can program. It has ports for up to four device modules, which snap in and out of place. Among the first modules the company expects to offer will be a GPS system, a camera, a motion sensor, and an LCD screen. But it also plans to offer new modules at a rate of about four per quarter, and it's encouraging other manufacturers to follow suit.

Software to double your cell phone memory

, ,

Compression algorithms are not really new, so I’ve looked cautiously at the work of U.S. computer scientists claiming that ‘they have developed technology that doubles the usable memory on cell phones and other embedded systems without any changes to hardware or applications.’

The CRAMES (Compressed RAM for Embedded Systems) technology uses the Linux kernel’s swapping mechanism to determine which pages should be compressed. According to the researchers, cell phones equipped with this technology don’t use more power than regular ones and show a very small performance loss. The first phone to use the CRAMES technology is sold by NEC — but only in Japan right now.

Now, how did the researchers designed their software? “The team’s approach was to divide the memory in the system into two different regions, one regular and one where the data is greatly compressed. A very simple example of data compression is converting a list of 50 individual ‘A’s into the phrase ‘50 As,’ which takes up less space but communicates the same information.

When technology gets personal

, ,

In 2020, whipping out your mobile phone to make a call will be quaintly passé. By then phones will be printed directly on to wrists, or other parts of the body, says Ian Pearson, BT's resident futurologist.

It's all part of what's known as a "pervasive ambient world", where "chips are everywhere".

Mr Pearson does not have a crystal ball. His job is to formulate ideas based on what science and technology are doing now, to guide industries into the future.

Inanimate objects will start to interact with us: we will be surrounded - on streets, in homes, in appliances, on our bodies and possibly in our heads - by things that "think".

Forget local area networks - these will be body area networks.
