Retro [geek] Corner - Fuji Instax 200 Instant Camera


It is already this time of the year, and I am preparing for Nordcon - science-fiction assembly. This year dress up code is Steampunk - dark, Victorian atmosphere mixed with advanced industrial revolution bizarre gear. Where Turing machine is actually self-conscious and everyone wears goggles because of the smog and dust. Good times...

Anyway, I thought that I will use this opportunity to recover some of the artifacts of old technologies, that were once (quite recently) defining the reality, but are now more or less dead. I was browsing in my retro geek corner, and in the first review it is Fuji Instax 200 Instant Camera, sold by Fuji since... mid 90's.

I love this peace of gear. Extremely simple to use, and with the press of a button you produce a 10 cm x 6.3 cm photo that comes out from the top slot with lots of satisfying noises and twirls. When you turn it on people stare. People stare even when you take it out of the bag. And they are very surprised, shocked and amused at the same time.

Camera produces photos which are wider and more rich in terms of color depth comparing to well-known Polaroid One with 600 film. Fuji Instax external look misses some of the elegant aesthetics of Polaroid instant cameras, but it is still a party animal, with flash, two options of focus and three sensitivity modes. Crude. But I feel I need to exploit it in incoming Nordcon (although it is really not a Steampunk piece, nobody will care;-)


Why do I still love instant camera, in the reality where I can make thousands of photos with my iPhone or any other digital camera? It is the crudeness, grittiness and material evidence of your photographic crimes, which comes instantly, and which you can share in a very different way than digital photo on a small shitty display. You can write on it. And it is generally a social thing.

Digital photos are done without any philosophy behind them, because person is not limited by film capacity. Digital photos are freeware, they don't cost you anything so you just shot them without thinking much about it. On the other hand instant photos have a value, they not cheap, and they certainly require some thought, otherwise they will come up crap. In Fuji you need to think about distance between your focus lens and viewfinder, and adjust your position, otherwise you will shot a photo somewhere next to your target.

Fuji Instax is a kind of technology, that has certainly died from the hands of digital photography, but it is still intelligent and social type of camera. And although you can consider it as a dinosaur technology, Fuji is still making films for it, in contrast with Polaroid.

It is simply the great retro geek machine, 8 out of 10 stars.

Virtual Dresses and Skin Displays

Today something for geek chicks out there. Some hot tech-news from the world of fashion.

First - you have a trouble with deciding whether to buy this online dress? Not sure about the size, or how it will go with your jewelery? Well, folks at Tobi Shopping created Virtual Dressing Room, Fashionista. It works as augmented reality, so you print a special marker, stand in front of your computer camera, and just change the dresses or other clothing that overlay on the top of your body image, with everything showed in your browser display in a real time. With printed marker you adjust the position of the dress in the virtual camera space. It is a bit crude, but very interesting idea in terms of applying augmented reality in the user interface. I tested it with Ola, and she got hooked on it quite quickly. Below are her photos with the virtual dresses :) But watch the tutorial before you try the dresses.

Second - remember those gang members from Gibson's Virtual Light? Or drummers from Stephenson's Diamond Age? Yes, the ones with interactive tattoos which were displaying different images under their skin depending on emotions and their behavior. Now research team from University of Pennsylvania finally made it, with the LED tattoos technology that can turn your skin into the full color screen. Those LED's will be the combination of silicon microchip with silk substrate, allowing the chip to smoothly dissolve into your body. Unnoticeable microelectronics implanted in the surface of your skin will allow to hook it to any electronic device, displaying anything you want. They will be also useful in diagnostic aspects, like monitoring vital metabolic signals, blood pressure, etc. Initial displays will be black and quite basic, but the potential application for the future is limitless, from full body displays to microchips being implanted to your retina to regulate the amount of light coming to your eye or displaying augmented reality. Philips is already exploring some commercial use of electronic tattoos. It is a bit creepy, but... I love it ;-)

Woman Addicted to Brain Implant

I have been organizing my papers over the weekend and I found this 1986 paper from Pain journal which describes the first ever case recorded of a woman addicted to deep brain stimulation implant.

The described patient (48 years old) has been suffering from chronic pain for over 15 years, with a recorded history of heavy addiction to opium-based painkillers and alcohol. It was established by psychiatrists that the best course of treatment for the pain would be to use an implant located in thalamus. Indeed, during the self-stimulation the pain has been removed, but as a unexpected side effect, she has been also experiencing an erotic sensation (although without orgasm).

As a result, she started stimulating herself throughout the day, neglecting family commitments and personal hygiene. She also developed ulceration on the top of her finger used to adjust the amplitude dial for brain implant. Over the two years after the implant was installed, her compulsive use of the stimulation dial has been associated with 'frequent attacks of anxiety, depersonalization, periods of psychogenic polydipsia and virtually complete inactivity' [1]. She also developed a heart disturbance (paroxysmal atrial tachycardia).

I read this paper thinking about those experiments with rats who pressed button every second to produce the pleasant stimulation via brain implant, until they died from exhaustion. How closely related we are all in the animal kingdom...

The Road Train

Your remember cars in Minority Report or Total Recall?

Cars that didn't need a driver action to operate them?

Cars which drive itself while you have a lunch, read a book or watch a movie?

Well, soon it will be here, in our lovely Europe! How soon? Within next 10 years, with the trials starting in 2011!

As a part of European Union Safe Road Trains for the Environment initiative (or SARTRE) cars with similar destinations over long highways will be grouped together into road trains. The lead vehicle will be driven by an experienced motorist, like bus or truck driver, that regularly travels that road. One train will include between 6-8 cars. At any time you will be able to join the train. Then the onboard computer takes over the vehicle and you can relax and enjoy your bacon roll.

Simple.

The most exciting is that there is no need for infrastructure investment. All modification would have to be done on the vehicle level.

I can already see myself reading e-book comfortably while behind the wheel.

And last point – despite the project name, cars can exit from car train anytime ;-)

Neurointerface

William Gibson in his 1984 novel Neuromancer predicted that we might connect the computer to our brain. His dark story was a fiction 25 years ago, but now it becomes a reality.

We are closer than ever to interface our brain with the computer.

One of the most promising developments is BrainGate (currently during clinical trials conducted by Cyberkinetics). BrainGate consist of a sensor in the form of sophisticated micro-electrodes implanted directly into motor cortex and a decoder - dedicated software translating brain activity into useful commands for external devices. At this stage the majority of tests are conducted in patients with severe forms of paralysis, like Quadriplegia or Locked-in syndrome.

Application? Prosthetic limbs control, complex computer operation with augmented reality, therapy for neuronal-based disorder (in expansion of deep-brain stimulation).


Certainly, we don't know enough about the brain at this stage to be able to create complex interfaces, but even hooking motor cortex with functional microchip will be a milestone in neurocybernetics.

Problems?

What problems? ;-)

But seriously, one outlined in this month issue of Wired is neurosecurity. Folks at the Medical Device Security Center (MDSC) showed that they could reprogram implantable hearth regulator with simple radio equipment. Now, think about your neuroimplant being hacked, and your prosthetic limb, anti-depressive brain stimulator or remote control function (;-) taken over? So MDSC is now developing encrypting security methods for neuroimplants.

A Firewall for your brain.

The Future of Drugs - Part 1

Society seems to have a problem with deciding what to do with drugs. Certainly it seems that liberalization and legalization is increasingly possible scenario for the future. Status of cannabis in Netherlands, therapy models for heroin addicts in Switzerland, return of research on healthy participants with THC, LSD for anxiety related treatment and MDMA for post-traumatic stress disorder or all drugs decriminalization experiments in some Portugal cities... Those are just a few examples showing that open minded and objective approach to drugs can work better than law enforcement and criminalization.

There has been a heated discussion in the recent days in UK regarding sacking of Prof David Nutt, who was a Head of Advisory Council on the Misuse of Drugs (ACMD). It was related with Prof Nutt’s lecture at King’s Collage, where he suggested that decision to reclassify cannabis from class C to class B drug was politically motivated against the suggestions of scientific advisers (and that overall cannabis is less harmful than alcohol and tobacco). After Home Secretary decision to sack Prof Nutt, two other advisers resigned in protest, and the whole scientific panel is raging.

Professor Nutts actually gave a very good review during this lecture which you can read in this briefing from Center of Crime and Justice Studies. I strongly recommend you to read it. Prof Nutt argue that such factors as harm assessment bias, media bias and political stigmatization are just some of the problems that so far prevented most countries from application of multicriteria decision-making in classification and general approach to drugs.

Governments applied this multicriteria decission-making model in case of nuclear waste disposal or terrorist threat assessment so why is scientists’ voice so badly ignored regarding drugs?
