Heart monitors hacked

2 Comments

heart-mosaic I don’t need to remind you that computers are everywhere – this is the intarwub, after all. But even I get a bit surprised at some of the specific places computers end up – I never knew that people are being implanted with heart monitor/defibrillators that can broadcast data about the patient’s condition back to their doctor.

Having found that out, though, I’m not at all surprised to hear that researchers have found a security vulnerability that could potentially allow an attacker to compromise and deactivate the device and prevent it from delivering the heart-restarting shocks it is designed for.

Repeat after me – everything can and will be hacked.

On the subject of electric shocks to the body, you can choose to have them for fun as opposed to for your health; the grinders point out the arrival of the Mindwire V5 electroshock force-feedback device, which will interface with your games console and deliver a brisk jolt to your hands when you get PWNED. Pain is fun, kids!

"Mind-reading" machines beginning to appear

3 Comments

RobertFuddBewusstsein17Jh A neckband that picks up nerve signals and translates them into speech has been demonstrated for the first time. (Via NewScientistTech.)

With training, a user can send nerve signals to their vocal cords without making a sound that the neckband picks up and relays wirelessly to a computer, which then converts them into words spoken by a voice synthesizer.

This same device has been used to let people control wheelchairs using their thoughts.

Currently the system, called Audeo, can only recognize a limited set of about 150 words and phrases, but by the end of the year there’s supposed to be an improved version without a vocabulary limit. Although it will be slower–it’s based on phonemes, not whole words–it will allow people to say whatever they want, and should be a boon to people who have lost the ability to speak due to disease or injury.

It’s not the only “mind-reading” technology that’s been in the news recently, either. Researchers at the University of California have developed a system that uses functional MRI data to decode information from the visual cortex. Using it, the scientists were able to figure out which of more than 100 previously unseen photographs subjects were looking at.

What lies at the end of that road? Possibly the ability to access dreams and memories–assuming the way the brain processes dreams is analogous to visual stimuli.

And then there’s the “mind-reading” car that monitors a driver’s brain activity and reduces the amount of information displayed on the dash during stressful periods. In tests, the system has speeded up driver’s reactions by as much as 100 milliseconds–equivalent to reducing braking distance by nearly three metres at 100 kilometres per hour.

The phrase “I know what you’re thinking” has thus far only been addressed by one human to another, and only in a metaphorical sense.

Someday soon, our machines could make it literal.

Sins of A Solar Empire game developer talks piracy

3 Comments

Sins of a Solar Empire has an impressive scaling of graphics to suit your machine

Sins of A Solar Empire by small independent game company Stardock (and their developers Ironclad) is the biggest selling pc game of 2008 so far, despite a tiny budget and much less coverage by the gaming press.  Stardock owner Brad Wardell posted an excellent analysis of why their games are having success. (last year’s Galactic Civilisations II was another underground hit.)

He talks a lot about the bad policies taken by much of the PC game industry. For example, why bother targeting the Chinese market when piracy is so rife many people won’t purchase your game? His main point, and it’s a very good one, is that very few people upgrade their computer often so targeting the graphics of your game to only work for the ‘hardcore’ pc gamers is limiting your market. Rather than trying to break the latest processor if you just make a game that’s fun and works on most computers people will play it.

Sins is a fun game that combines the 4X ideas of ‘eXplore, eXpand, eXploit and eXterminate’ of games like Civilisation with Real Time Strategy elements of space games like Homeworld. I’ve enjoyed myself whenever I’ve played it but what’s even more impressive is the attitude of the people behind it – updates are frequent, there’s no DRM, the developers comment frequently on the game’s forum and they listen to requests from players about bugs and new features. In an industry full of high budget Hollywood games, it’s comforting to see that small companies can be a big success if they just concentrate on pleasing their audience.

Transparency bites – Brin blasts back

transparent-train-carriage Wired has given David Brin some rebuttal space to defend his Transparent Society concept in response to Bruce Schneier’s recent criticisms (as covered earlier here on Futurismic):

“How did we get the freedom we already have, becoming the first civilization in history to (somewhat) defy ancient patterns? Yes, it’s imperfect, always under threat. We swim against hard currents of human nature. But reciprocal accountability is the innovation that lets us even try.

Schneier claims that The Transparent Society doesn’t address “the inherent value of privacy.” But several chapters do, and I conclude that privacy is an inherent human need, too important to leave in the hands of state elites, who are themselves following ornate information-control rules written by other elites — rules, by the way, that never work. (Robert Heinlein said “‘privacy laws’ only make the bugs smaller.”)”

Going back and reading Schneier’s piece again, it does seem like he’s arguing a similar point from a different direction – they’re both opposed to top-heavy hierarchies of control. It would be great if Wired could arrange some sort of formal public debate between Schneier and Brin – the topic has never been more relevant, after all, and as Cory Doctorow points out, talking about these issues is the best way to ensure things don’t get any worse.

Alpha Centauri ‘should have an Earth-like planet’

18 Comments

An artist’s impression of an earth-like planet around Alpha CentauriAlpha Centauri is the closest star system to our own but with a bonus: there are three stars rather than one. It’s also one of the best chances we know in the local area to have a planet similar to Earth capable of developing life like ours.

If any planet were to harbour earth-like life in the three-star system, it would likely be around Alpha Centauri A, which is most similar to the sun. However astronomer Javier Guedes and his coauthors believe that Alpha Centauri B is likely to have terrestrial planets in its habitable region. Based on computer simulations of planet formation, Guedes and his team found that no matter what starting conditions, a terrestrial planet always formed around the star. By studying the ‘wobbles’ the planet causes on its parent star, the team reckon they could find any potential planets within a few years.
