neuro-electronics and cognitive computing

Nik — Wed, 14 Sep 2011 09:25:41 +0000

In 2001 researchers from the Max Planck Institute made a breakthrough in so-called neuro-electronics by “Interfacing a silicon chip to pairs of snail neurons connected by electrical synapses“. In the meantime we have seen progress in brain gate experiments, in implants to provide relief for a people with Parkinson’s disease, neuro-prosthetics to help memory function in Alzheimer patient, neuro-engineers over at Stanford University are trying to create a silicon version of the human cortex through neuromorphing (transistor-based neurons & neural circuits), the Human Brain Project brings together 13 universities, research institutes and hospital with the aim of building a European research facility that will simulate the human brain and exploit the results etc.

Recently, IBM researchers unveiled “a new generation of experimental computer chips designed to emulate the brain’s abilities for perception, action and cognition.” The so-called ‘cognitive computing chips’ have been developed within the context of the DARPA funded SyNAPSE project.

“Making sense of real-time input flowing in at a dizzying rate is a Herculean task for today’s computers, but would be natural for a brain-inspired system. Using advanced algorithms and silicon circuitry, cognitive computers learn through experiences, find correlations, create hypotheses, and remember—and learn from—the outcomes.

For example, a cognitive computing system monitoring the world’s water supply could contain a network of sensors and actuators that constantly record and report metrics such as temperature, pressure, wave height, acoustics and ocean tide, and issue tsunami warnings based on its decision making.”

See also IBM’s Dharmendra S. Modha’s keynote video on cognitive computing.

In a way – by having a chip learn ‘in situ’ in the brain or any neurological situation for that matter and transfer the learned patterns to another implantable chip – the technology can be said to point towards a wetware version of Douglas Engelbart’s notion of Intelligence Augmentation.

As it is usually the case with such breakthrough developments, people’s imagination runs wild. What if we could transfer ‘tricks’ related to how animals process sensory signals to the human? What if next-generation thieves would start stealing skills by adding something to you rather than taking something away? What if humanitarian emergency situations could benefit from these advances by ‘broadcasting skills’? What if the microchip could become fully bio-based? The past weeks we have seen everything from benevolent neuro-prosthetics to Manchurian Candidate-like scenarios pass the revue. While advanced applications might still be years off, the societal debate around the possible impacts of envisioned uses for these technologies is worth carrying out now.

necomimi

Nik — Mon, 13 Jun 2011 19:29:05 +0000

While we move from ‘touch’ to ‘gesture’, interacting with our technology directly via brainwaves seems to be up next. We have already seen games such as brainball or mindball and even wheelchairs controlled via brainwaves. Now recently, the Japanese firm Neurowear launched Necomimi (check out the video), a set of brainwave-controlled cat-ears. Concentrate and the ears stand up, relax and they lay down: a poetic way of rendering aspects of one’s state of mind visible to surrounding individuals.

It makes one wonder which cues about our state of mind, now subtly hidden below our behavioural surface, more or less beyond reach of direct sensorial detection, one would like to share with others? How would we use the information? How would it enhance the bandwidth of our communicative spectrum? Which new challenges would it pose to interpersonal relationships?

Tapping into the state of mind – e.g. being concentrated or not – is one thing, tapping into what the brainwaves are actually about another. Belgian Prof. Philippe Schyns and his team at the University of Glasgow recently succeeded in ‘reading’ brainwave information related to visual perception (see here).

On a more artistic note, do not forget to check out Christophe De Boeck’s Staalhemel, “an interactive installation with 80 steel segments suspended over the visitor’s head as he walks through the space. Tiny hammers tap rhythmical patterns on the steel plates, activated by the brainwaves of the visitor who wears a portable EEG scanner.”

big data & big cities

emiel — Mon, 13 Jun 2011 09:13:34 +0000

The McKinsey Global Institute has recently published a report on Big Data , defined as “datasets whose size is beyond the ability of typical database software tools to capture, store, manage and analyze”. The authors expect that big data will play a significant role in having/letting businesses and governments operate in a more efficient and qualitative way, which, amongst others, should effectuate a more thorough relation between companies, institutions and consumers/the public, leading to innovation and economic growth. At the same time researchers emphasize the complexity of the interpretation of big data: new analytic software and specialized analysts would be needed.

One may well call Geoffrey West, physicist and former president of the SantaFe Institute such a specialist. Via reasoning inspired by metabolic processes West is developing quantitative, analytic, mathemitizable, predictive frameworks in order to understand how cities – complex social systems – work exactly. One of his findings is that, unlike other physical and biological processes cities do become more efficient: the bigger the city, the (exponentially) higher its production and wages. In cities, more patents are produced, they are more innovative …

Based on these findings the growth of cities is a positive trend. From the point of view of sustainability also major advantages of living in a city can be discerned. The impact smaller towns have on the environment are relatively high. Based on this understanding the Chinese government had hundreds of thousands of people move from the rural Ordos plains to the newly buit Ordos City. In “City vs Country: The concrete jungle is greener” Shanta Barley gives some more examples of why densification of cities should be supported:

The carbon footprint of inhabitants becomes lower
The scale of waste generation becomes substantial enough to be an efficient and economical resource for energy production
It helps decreasing overpopulation since urban women have better access to family planning and birth control, often have better employment opportunities and have their first child later.

How would these insights and examples contribute to the ongoing debates on sustainability? One could argue that these developments support efficiency, no substantial change. By all means they clearly stem from a belief in or the need for technology to solve sustainability issues instead of finding new ways to bring more balance in the earth’s ecosystem (Medea vs. Gaia Hypothesis).

Exaggerating, one could say that West believes that the closer one would bring people together, the better the ideas will pop up. However, West also realizes that with the pace of growth of cities, it will be hard for human kind to keep being innovative…

america 2049

Nik — Thu, 14 Apr 2011 18:28:52 +0000

April 4, 2011, was the launchdate of a new ARG (alternate reality game) entitled America 2049. The game is a 12-week episodic experience blending today’s world with a possible future world. The game fuels the debate on human rights issues linked to the thin line between the enabling aspect of certain identity-related technologies and the way in which they expose civil rights to abuse from both private and government sectors.

“In America 2049, the former land of the free has degenerated into the Divided States of America, where sexuality, religion, speech and culture are all controlled and restricted. On the upside: the entire population is on a drug that inhibits aggressive behavior called SerennAide, administered automatically through the water supply. This has led to a decrease in crime rates, an increase in the population’s happiness, and has purportedly helped people to rise above their worst impulses.

Depending on where you stand, this is either a Utopian dream or an Orwellian nightmare. And it is up to you to decide where you stand: alongside the Council for American Heritage (CAH), or with Divided We Fall (DWF).”

Behind the game stands Fuel | We power change , a creative agency focussing on the non-profit sector.

A great way to render the future tangible and use an immersive experience to explore and trigger debate on certain societal issues. Fascinating also that different cultural perspectives are embedded in the devised storylines.

a touch of glass

Nik — Fri, 08 Apr 2011 09:44:11 +0000

High-end glass (and ceramics) producer Corning recently created a nice video showing a day in the life of a family in a world of … glass. The video basically shows the world as one big touch screen (without greasy fingers). Obviously, from today’s perspective, the success of touchscreens are one big pointer to a future of ‘more’. Yet, there are also various elements equally present in today’s world that point in other directions.

One the one hand, while there is plenty of room for innovative and more natural interaction patterns – touch definitely being one of them, but also gesture of course – there are also plenty of worries abound that the increasing amounts of information, presented visually in our daily environments, are leading to situations of sensorial and cognitive overload on the user end. On the other hand, glass is not the only material able to render surfaces and the world around us interactive. Just think about all the advances in smart textiles (check out also Ryan and Francesca’s inspiring work over at CuteCircuit as well as that of Marina over at by-wire) or the skin as an interface (see also CMU’s Chris Harrison’s Skinput and a previous blogpost on “skinterfaces“).

The future of touch also goes beyond the ‘one-way’ touch that we are currently used to. Bayer Material Science and its subsidiary Artificial Muscle for example, developed electroactive polymers that enable devices and screens to provide tactile feedback. In other words, the surface might be smooth, but you feel texture.

On a sidenote … While many still associate the advent of touch screens with the launch of the iPhone and derivatives or Jeff Han‘s large-format interactive screens, the history of many of the interaction patterns involved goes back to the nineties. In 1999, for example, the former GMD-IPSI’s (now Frauenhofer-IPSI) Ambiente Lab – active in CSCW and other areas – presented their vision of workplaces of the future entitled i-LAND. Already, one could tap, swipe, even push documents from an interactive table to an interactive wall.

a 100 year starship

Nik — Mon, 24 Jan 2011 12:55:13 +0000

Spotted some time ago … NASA and DARPA have freed up some budget ($1.1 million) to envision what a 100 year starship could be like (see article). According to NASA Ames director Simon P. Worden we could be on the moons of Mars by 2030. Check out his conversation with Peter Schwartz over at the Long Now Foundation.

Considering distance and travel-time, first missions will most likely be one-way only. Transporting first settlers, implies the need to turn our destination into somewhat of an inhabitable context for human and terrestrial life. According to Prof. dr. Dave Wilkinson, we might learn from the way in which Darwin succeeded in ‘terraforming’ Ascension island in the middle of the Atlantic about 160 years ago.

From a ‘what if?’ perspective, a 100 year voyage raises interesting questions, especially when they extend beyond the technological realm: How will ‘grandchildren’ born in space, who have never seen their ‘home planet’, think about ‘their mission’? How will they relate to ‘Mother(planet) Earth’? What would be needed to keep people focussed on a multigenerational mission and live peacefully and in good physical and mental health within a confined space? How could/would their society develop? Which plants, animals and terraforming equipment would be sent along? The challenges are manifold (see ‘Mars is hard’).

bionic handling assistant

Nik — Wed, 19 Jan 2011 19:00:55 +0000

The 2010 German Future Prize – aka the Deutscher Zukunftspreis, a true prize with 250.000 euros for the winner(s) – went to Festo and Fraunhofer IPA for their Bionic Handling Assistant. Festo has a long history in biomimetic systems and also this time nature provides inspiration for their innovative design: the elephant’s trunk. Robust yet gentle, flexible yet precise.

“The plastic trunk is made of bellows structures arrayed in series, a movable hand axis and a grabber with three fingers,” explains Dr. Post, who heads up the research and development project at Festo. The structural elements are flexible and can be manipulated using compressed air. If air is pumped into the trunk, the bellows structures extend as an accordion would. This is how the high-tech trunk can be extended from 70 to 110 centimeters in length.

The three fingers fitted to the trunk are also designed with a biological model in mind – the tail fin of a trout. The special feature: if you press these “FinGrippers” lightly with your finger, rather than retract in the direction of the pressure, they respond by moving toward the source of pressure.

The individual structural elements of the flexible arm are produced in additive manufacturing.

robots

Nik — Fri, 10 Sep 2010 14:22:09 +0000

BaR2D2 serves drinks, Asimo walks the planet as man’s new best friend, NASA’s Robonaut 2 takes to space and loves to twitter. Robots continue to inspire. Several exhibitions currently on show give a glimpse of some highly creative – even poetic – robotic tinkering by artists.

Hangar311 in Mechelen (B), puts the inspiring work of Stéphane Halleux on show. Tinguely meets ToyStory in a steampunk version.

Our friends over at the Maison d’Ailleurs in Yverdon-les-Bains (CH) focus on the work of new media artist, author and theorist Ken Rinaldo in their exhibition entitled “Do robots dream of spring?”.

Ken Rinaldo’s art promotes communication between species. By creating immersive environments, the artist presents works to be experienced. He puts human beings in our rightful place, one that is integrated into vast systems, of which we are simultaneously the architects, the prisoners and the custodians. He shows us that our environment is an immense meeting place where worlds collide, a place of shifting borders, which he encourages us to explore.

The Tinguely Museum (in cooperation with Kunsthaus Graz) takes a closer look at artificial intelligence and robotics in their 1000m2 exhibition Robot Dreams.

Enjoy!

personal aviation vehicles

Nik — Thu, 21 Jan 2010 17:20:10 +0000

Which better way to jumpstart the year than to have another look at personal aviation initiatives (see also earlier posts here and here). The online buzz seems to prove that not even a crisis can silence those dreaming about personal aviation vehicles (PAV’s): e.g. Mirror Image Aerospace’s Skywalker VTOL, the PAL-V. Urban Aeronautics‘ X-Hawk does away with the external propellors, after all a much lamented nuisance for VTOL PAV’s in crowded urban environments.

A lot of effort seems to go into VTOL (vertical take-off and landing) configurations, as can be seen in for example the video of this Buzz Lightyear-like low-noise electric VTOL PAV. Yet, there is also the Spiral Duct ESTOL Concept. NASA apparently also took inspiration from Transformers and shows how a car can be turned into a personal air vehicle (see video). For more PAV-videos, check out NASAPav.

Although a few years old, the article entitled “These legs are made for walking” (Discover Magazine) presents a concise overview of five visionaries and how they see beyond vehicles as we know them, first of all by questioning the assumptions underlying them today. James Kuffner (Head of Planning and Autonomy Lab at the Robotics Institute of Carnegie Mellon University) for example asks “why wheels?”, his lab colleague Chris Urmson asks “why a driver?”. Brian Seeley (eye surgeon and founder of the CAFE (Comparative Aircraft Flying Efficiency) Foundation, check out their blog here) shares thoughts on flying cars, while Robert Thompson (director of the Bleier Center for Television and Popular Culture at Syracuse University) questions the US’ infatuation with gas-guzzling cars and conjures ecochic pint-size autos with moss roofs. Peter ‘X-Prize‘ Diamandis thinks about truly personalized cars, i.e. shape your own carbon-nanotube impregnated composite bodies.

peak lithium?

Nik — Mon, 21 Sep 2009 19:38:24 +0000

As car manufacturers shift away from oil and towards electricity to power our future vehicles, a new race is on. The target this time: lithium, basis for the lithium-ion batteries to be found in everything from electric vehicles, to mobile phones, cellphones, laptops, anti-depressives etc. The place: Chile (for now), Bolivia (next) … The salt lakes near Uyuni in Bolivia are believed to contain an estimated 28 millions tons of lithium, or 90% of the world’s reserve according to experts. The car industry currently runs on 16.000 tons per year. As the production and demand of electric cars ramp up, the demand for lithium is expected to be anywhere between 54.000 and 500.000 tons per year. At such rates, estimates of shortages starting from as early as 2015 are no exception as automobile, pharma, ICT and many other industries will be fishing in the same pond for the same type of fish.

Although lithium is no fuel (it is not consumed through usage) and lithium-ion batteries ‘can be recycled’ (note: they do contain substances harmful to the environment in case they should end up in landfills and pollute water reserves) other worries arise concerning the socio-economic impact of lithium mining activities in the aforementioned countries.

On a more fundamental level – a more philosophical one if you wish – nature and history teach us that monoculture is generally a bad idea (cf. resilience). So whether we like it or not, we need to (re)learn to think in terms of a mix, of diversity once again.
