"Just what the doctor ordered? A new breed of throwable games controllers could turn computer gaming into a healthy pastime, reckons one Californian inventor. His "tossable peripherals" aim to get lazy console gamers up off the couch and out into the fresh air.

Each controller resembles a normal throwable object, like a beach ball, a football or a Frisbee. But they also connect via WiFi to a games console, like the PlayStation Portable. And each also contains an accelerometer capable of detecting speed and impact, an altimeter, a timer and a GPS receiver.

The connected console can then orchestrate a game of catch, awarding points for a good catch or deducting them if the peripheral is dropped hard on the ground. Or perhaps the challenge could be to can throw the object furthest, highest or fastest, with the connected computer keeping track of different competitors' scores.

Hardcore gamers, who cannot bear to be separated from a computer screen, could wear a head-mounted display that shows scores and other information. The peripheral can also emit a bleeps when it has been still for too long, to help the owner locate it in the long grass"

The increased focus on children’s role in the design and evaluation of interactive technologies has provided several interesting research studies and results. Currently, we are aware of the fact that children are very different than adults, they are independent individuals with their own strong opinions, needs, likes, and dislikes, and they should be treated as such.

To address emerging research and development, IDC 2007 will look for papers, demonstrations, posters that may include at least one of the following broad areas: 

-  Emerging technologies for children (e.g., innovative educational simulations, online games, accessible fabrication devices, mobile communications devices, wireless embedded technologies, sensors and actuators, "smart" materials, authoring/programming tools) 

- The impact these technologies can have on children's lives (e.g., in schools, at home, in public spaces) 

- New research methods which give children a voice in the design, development, and evaluation processes (e.g., participatory design methods, usability testing, etc.)

Please refer to the call for papers.

In a new article from the Journal of Medical Internet Research, Kenneth Adler of Tuscon reports on his study of 346 patients in his practice regarding their use of online services and willingness to pay for them. Conclusion: patient's of any age would be willing to pay $10 per year for a web portal where they could view their test results and other medical information. While this may seem small, the author points out that if around 50% of patients in a large practice were willing to pay this, the program would pay for itself.  Reimbursement for email consultations or eVisits is still rare so this business model is one to consider.

Recovery of hand function through mental practice: A study protocol.

BMC Neurol. 2006 Oct 26;6(1):39

Authors: Ietswaart M, Johnston M, Dijkerman HC, Scott CL, Joice SA, Hamilton S, Macwalter RS

BACKGROUND: The study aims to assess the therapeutic benefits of motor imagery training in stroke patients with persistent motor weakness. There is evidence to suggest that mental rehearsal of movement can produce effects normally attributed to practising the actual movements. Imagining hand movements could stimulate the redistribution of brain activity, which accompanies recovery of hand function, thus resulting in a reduced motor deficit. Methods/ Design A multi-centre randomised controlled trial recruiting individuals between one and six months post-stroke ( n = 135). Patients are assessed before and after a four-week evaluation period. In this trial, 45 patients daily mentally rehearse movements with their affected arm under close supervision. Their recovery is compared to 45 patients who perform closely supervised non-motor mental rehearsal, and 45 patients who are not engaged in a training program. Motor imagery training effectiveness is evaluated using outcome measures of motor function, psychological processes, and level of disability. DISCUSSION: The idea of enhancing motor recovery through the use of motor imagery rehabilitation techniques is important with potential implications for clinical practice. The techniques evaluated as part of this randomised controlled trial are informed by the current understanding in cognitive neuroscience and the trial is both of scientific and applied interest.

Brain-machine interfaces: past, present and future.

Trends Neurosci. 2006 Sep;29(9):536-46

Authors: Lebedev MA, Nicolelis MA

Since the original demonstration that electrical activity generated by ensembles of cortical neurons can be employed directly to control a robotic manipulator, research on brain-machine interfaces (BMIs) has experienced an impressive growth. Today BMIs designed for both experimental and clinical studies can translate raw neuronal signals into motor commands that reproduce arm reaching and hand grasping movements in artificial actuators. Clearly, these developments hold promise for the restoration of limb mobility in paralyzed subjects. However, as we review here, before this goal can be reached several bottlenecks have to be passed. These include designing a fully implantable biocompatible recording device, further developing real-time computational algorithms, introducing a method for providing the brain with sensory feedback from the actuators, and designing and building artificial prostheses that can be controlled directly by brain-derived signals. By reaching these milestones, future BMIs will be able to drive and control revolutionary prostheses that feel and act like the human arm.

British and U.S. researchers have developed a cloak that renders the wearer invisible. The shield, a set of metamaterial concentric rings, can redirect microwave beams so they flow around a “hidden” object inside. The cloak is designed for operation over a band of microwave frequencies, and works only in two dimensions.

Metamaterial Electromagnetic Cloak at Microwave Frequencies.

Authors: D. Schurig, J.J. Mock, B.J. Justice, S.A. Cummer, J.B. Pendry, A.F. Starr, D.R. Smith.
Science DOI: 10.1126/science.1133628

Recently published theory has suggested that a cloak of invisibility is in principle possible, at least over a narrow frequency band. We present here the first practical realization of such a cloak: in our demonstration, a copper cylinder is 'hidden' inside a cloak constructed according to the previous theoretical prescription. The cloak is constructed using artificially structured metamaterials, designed for operation over a band of microwave frequencies. The cloak decreases scattering from the hidden object whilst at the same time reducing its shadow, so that the cloak and object combined begin to resemble free space.

An experimental study of the emergence of human communication systems [pdf]

Author: B. Galantucci

Cognitive Science, (29):737–767, 2005.

The emergence of human communication systems is typically investigated via 2 approaches with complementary strengths and weaknesses: naturalistic studies and computer simulations. This study was conducted with a method that combines these approaches. Pairs of participants playedvideogames requiring communication. Members of a pair were physically separated but exchanged graphic signals through a medium that prevented the use of standard symbols (e.g., letters). Communication systems emerged and developed rapidly during the games, integrating the use of explicit signs with information implicitly available to players and silent behavior-coordinating procedures. The systems that emerged suggest 3 conclusions: (a)signs originate from different mappings;(b)sign systems developp arsimoniously; (c) sign forms are perceptually distinct, easy to produce, and tolerant to variations.

"Global Conflict: Palestine gives the option of three perspectives. A game based in the midst of the conflict in the Palestinian territories is set to be the latest release in the trend of politically-conscious gaming. Global Conflict: Palestine centres on the activities of a young journalist. The player must navigate between different Palestinian and Israeli sources to get to the truth of a story. "You can take a pro-Palestinian angle, a balanced angle, or a pro-Israeli angle," said Simon Egenfeldt-Nielsen, of Serious Games Interactive. Mr Egenfeldt-Nielsen told the BBC's Culture Shock programme: "The game is much more about the personal experience; the emotional experience."

The player walks around a city resembling Jerusalem and its surrounding areas talking to people. As the conflict intensifies, however, the situation becomes increasingly complex and exposes some of the reasons for the ongoing violence ... Different perspectives: Global Conflict: Palestine, which is released early next year, follows music channel MTV's internet-based Darfur Is Dying, which went online earlier this year and had 700,000 players in its first month. Later, tens of thousands of players sent e-mail messages to politicians to urge action over Darfur."

Tiny chips, cheap sensors and the possibilities of emerging smart fabrics, conductive yarns and cheap wireless communication (bluetooth or even rfid) make wearables easier and cheaper to make. Arduino boards are small physical computing platforms: Arduino developed a fairly simple integrated development environment to deal with the small portable input/output board. With all these tools at our fingertips, nothing is stopping us from making our own smart coats, reactive hats and luminescent skirts.

To help you get started, Mediamatic is organizing a wearables workshop where you can develop your own Arduino-driven wearable. Assisted by Massimo Banzi, one of the creators of the Arduino board and several coding/soldering/sewing helpers, you have three days to make your prototype in the stimulating surroundings of the Mediamatic Winter Garden.

What?
During the workshop, you will design your own wearable. You will define the sensor inputs and the actuator outputs. You will program the Arduino board to react correctly to the different inputs. You will do this in Arduino's own IDE, which helps you write a kind of simplified Java code similar to Processing. Then you will stitch/glue/felt together your prototype so you can participate in the wearables fashion show!

Who?
Computer scientists, fashion designers, hardware hackers, art students, fabric experts, product developers, dancers- everyone is welcome. However, note that some technical affinity is required. Some experience in programming and electronics is useful, specifically in soldering and java, but not strictly necessary. We would advice participants to come in teams of max. 3 people, so you can distribute soldering, coding and sewing tasks.

Where?
The workshop will take place in the latest Mediamatic exhibition: the Winter Garden. The Winter Garden is an indoor botanical garden filled with plants and robots. From the minimalistic electronic creatures of Ralf Schreiber to the virtual forest of Michiel Samyn to the interactive plant by Christa Sommerer and
Laurent Mignonneau to the pheromone tinged garden benches of Mateusz Herczka and the communicative crickets of Felix Hess- the Winter Garden is full of wonders.

What to bring?
If there is a specific sensor or actuator you would like to use during the workshop, we advise you to bring it yourself. You can also bring the actual clothing article beforehand, and not sew it during the workshop, or you can bring fabric and other material for the base of your wearable. You'll have to bring your own laptop to do your coding, and we advise you to download the Arduino software and have a look at it beforehand. Also, bring lunch.

How to prepare?
Besides looking at the Arduino software you can have a look at the Mediamatic wearables reader - a collection of interesting articles, websites and blogposts that can get you started in the world of wearables. Virtual Platform and V2 are organizing a wearables symposium in Rotterdam called Fleshing Out the day before the Mediamatic Arduino workshop with speakers such as Ionat Zurr (SymbioticA: the art and science collaborative research laboratory), Tobie Kerridge (Royal College of Art, London) and Joanna Berzowska (Design and Computation Arts , Concordia University, Montreal).

When?
The Fleshing Out Symposium is on Thursday November 9th at V2. The Mediamatic Arduino Wearables Workshop is from Friday November 10th to Sunday November 12th. The Kiem Cuisine Wearables dinner is Friday at 19:30 at Mediamatic. The Wearables fashion show is Sunday evening at 18:00.

Costs?
The Fleshing out symposium costs 40 euros. Students receive a discount of 20 euros. The Wearable Arduino workshop costs 125 euros. Dutch students receive a discount of 50 euros.

Brain Waves Drawing: Live Performance by Hideki Nakazawa: Nov 4-5, 2006 at Fuchu Art Museum, Tokyo Supported by Nihon Kohden.

Not to Draw by Hand. To Draw by Brain: Artists usually draw pictures by hand with brushes or pencils. However, the activities of brains must be more important and essential than the ones of hands at the moment of creating art. Therefore, I decided to draw pictures with electrodes being set on my head through controlling the activities of my own brain. The curved lines so-called "brain waves" in medicine must be the "drawings" in the world of fine art, directly drawn by my brain without using hands.
