NTT DoCoMo Phone: You're Hungry, but Don't Eat Yet

"Your hunger level is 60%. Refrain from snacking even if you are hungry."

So reads the display on the Toshiba Regza phone on display at NTT DoCoMo's booth at the Ceatec electronics show this week in Japan. And it has a point. It's been a few hours since breakfast and I could definitely go for a quick ramen, but probably should wait until lunch.

A Bluetooth-enabled breathalyzer has analyzed my breath for acetone, which the body produces when body fat is consumed. If acetone levels are low, the theory is that the body is running on sugar and carbohydrates, and hasn't started burning fat yet.

Ceatec attendees line up to breath a few times into the breathalyzer devices, and few seconds later a nearby phone lights up with their numbers. The readings seem rough at best -- one healthy-looking man came up 150 percent hungry and several others all came up exactly 36 percent. The product has no firm launch date.

The research is part of DoCoMo's ongoing push to expand the role of mobile phones in everyday life. The country's largest carrier, it runs nearly half the handsets in Japan.

Also on display were a set of swappable cases that add various sensors to a phone, including a radiation detector and a bad breath analyzer.

The carrier also touted a high-speed charging service for its smartphones, that is under development. External battery cases made for NEC Medias smartphones could be fully charged in just 10 minutes, then provided another 50 percent to the phone's original battery.

The batteries are based on lithium-titanate technology, which is quick-charging but can have lower capacity than the traditional lithium-ion batteries used in mobile phones.

DoCoMo hopes to eventually build external batteries that work with a wide range of phones, then set up quick-charging stations at convenience stores and other locations.

A TouchPad for $49? Maybe If You're Rick Astley

With geeks still scrambling to get their hands on the last of Hewlett-Packard's US$99 TouchPads, a $49 deal just seems too good to be true.

And, as the thousand or so people who tried to buy cheap TouchPads on an HP look-alike website Tuesday learned, one should steer clear of things that seem too good to be true.

The prank site -- registered Tuesday as Hewlett-packard.org.uk -- looks legitimate. In fact, many of the links on the site go to real HP addresses.

But anyone who tries to buy the $49 TouchPad gets Rickrolled. It's a popular type of Internet prank where the victim clicks on a seemingly irresistible link -- a $49 TouchPad, or a sneak copy of a Kim Kardashian wedding video -- and ends up instead sitting through a YouTube clip of schmaltzy soul singer Rick Astley singing his 1987 hit, "Never Gonna Give You Up."

Clicking on the TouchPad's "Add to Cart" button brings up the Rick Astley video and the line, "srry no hp touchpad! looooool," along with a running count of how many people have been fooled (925 as this article was completed).

The prank website is registered by Phillip Sullivan of Los Angeles. Sullivan could not be reached Tuesday, and it's unclear whether the name is a pseudonym.

Corporations typically register domain names, even if they don't intend to use them, but in this case, the prankster was able to register a believable-looking domain, hewlett-packard.org.uk, that HP hadn't managed to snatch up.

The site could have been used for something much worse than a harmless prank, according to the Social-Engineering.org website, which first blogged about the prank HP site on Tuesday. "If this were actually a malicious scammer how many people would have clicked?" Social-Engineering.org wrote on its blog. "How many would have inserted credit card info?"

This isn't the first phoney TouchPad site to pop up. Yesterday HP warned about another fake TouchPad site, called Hptouchpadsale.com. "IT IS FAKE!! Do not buy from there," HP spokeswoman Bryna Corcoran said in a Twitter message.

Last week, HP announced it was killing off its iPad competitor due to poor sales. But when it slashed retail prices to $99 it transformed the TouchPad from a flop to a hot item. The TouchPad initially sold for $499.

Most U.S. retailers sold out of the devices quickly when the sale began Saturday, but people are still trying to find them online.
