Towards Partecipative Ecology: the OpenSpime project

OpenSpime is a project of a pervasive technology infrastructure that allows individuals and corporations to better understand their environment, through the use of a series of GPS-enabled sensors.

A brainchild of Leandro Agrò, Roberto Ostinelli and David Orban, OpenSpime was inspired by Bruce Sterling's vision of "Internet of Things". Sterling describes a new type of technological device called "spime", a physical object that is part of the internet as it becomes trackable in space and time, through pervasive RFID communications and GPS navigation.

In this sense, OpenSpime platform represents one of the first concrete attempt to turn Internet of Things into reality.  

The first spime they've designed is a sensor that can measure the CO2 level in parts-per-million in the surrounding air, and through a wireless connection can send that information back to the OpenSpime servers. There they can be mashed up and aggregated on Google Maps.

Cognitive processing and motor skill learning in motor-handicapped teenagers

Cognitive processing and motor skill learning in motor-handicapped teenagers: effects of learning method.

Somatosens Mot Res. 2007 Dec;24(4):163-9

Authors: Deviterne D, Gauchard GC, Lavisse D, Perrin PP

This study aimed to assess the efficiency of a motor skill learning method intended to promote learning course personalization through an increase in cognitive processing deployment in motor-handicapped persons. Thirty-three secondary school students volunteered to participate in an archery motor skill learning session, 11 motor-handicapped (MH(1)) and 11 able-bodied (AB) teenagers following a standard learning method, and 11 motor-handicapped teenagers following a cognitive enriched learning method (MH(2)) based on the use of an individually written and illustrated document. The results showed that MH(1) displayed lower performances than AB, both in terms of the mental representations of the movements expected and performed and of efficiency of the movement. On the other hand, MH(2) performances were higher than MH(1) for all these parameters, and similar to those of AB at the end of the learning session. Personalization of the learning course allowed optimization of the learning potential in motor-handicapped teenagers to resolve the difficulties inherent to their handicap.

Assessing human reorientation ability inside virtual reality environments

Assessing human reorientation ability inside virtual reality environments: the effects of retention interval and landmark characteristics.

Cogn Process. 2008 Mar 20;

Authors: Bosco A, Picucci L, Caffò AO, Lancioni GE, Gyselinck V

The purpose of the present study was to assess the navigational behaviour of adult humans following a disorientation procedure that perturbed their egocentric frame of reference. The assessment was carried out in a virtual reality (VR) environment by manipulating the disorientation procedure, the retention interval, the relative positions of target and landmark. The results of experiment I demonstrated that adding a physical rotation to a virtual disorientation procedure did not yield an additional decrease in searching performance. The results of experiment II showed that shortening the delay between study and test phase decreased the errors more markedly for geometric than landmark ones. An orientation specificity effect due to the manipulation of the relative position between target and landmark was discussed across the experiments. In conclusion, VR seemed to be a valuable method for studying human reorientation. Moreover, the virtual experimental setting involved here promoted knowledge of the relationship between working memory and spatial reorientation paradigm.

Physicality and Interaction: A Special Journal Issue of Interacting with Computers

Planned publication date: September 2008

Following the successful Physicality 2006 and Physicality 2007 International Workshops, which demonstrated the growing multi-disciplinary interest in this area of work, we invite submissions for this special issue on Physicality and Interaction for the interdisciplinary journal Interacting with Computers.

We live in an increasingly digital world yet our bodies and minds are naturally designed to interact with the physical. The products of the 21st century are and will be a synthesis of digital and physical elements embedded in new physical and social environments. As we design more hybrid physical/digital products, the distinctions for the user become blurred. It is therefore increasingly important that we understand what we gain, lose or confuse by the added digitality.

Augmented physical artefacts can be tailored and adapted to operate within a wide range of ecological settings. However, they also become more complex and require a fairly intensive design process to make them not simply practical and functional but also engaging. As a result, the need becomes even more pressing to comprehend the underlying computational intricacies, the physical form, properties and behaviour, the physical and social contexts, and the issues of aesthetics and creativity.

The issues in this field impact many areas of study: architecture, art, cognitive science, geography, human-computer interaction, philosophy, product design, sociology, tangible interface and ubiquitous computing.

We invite contributions that address physicality at various levels, including:

- design at the physical-digital frontier
- the philosophy of physicality
- artefact-focussed social interaction
- physically-inspired interaction in virtual worlds
- creativity and materiality
- interactive art and performance
- digital emulation of the physical
- the evolving role of digital artefacts in material culture

A second life for AI

Source: Eetimes 

Passing the Turing test - the holy grail of AI (a human conversing with a computer can't tell it's not human) - may now be possible in a limited way with the world's fastest supercomputer (IBM's Blue Gene) and mimicking the behavior of a human-controlled avatar in a virtual world, according to AI experts at Rensselaer Polytechnic Institute. "We are building a knowledge base that corresponds to all of the relevant background for our synthetic character--where he went to school, what his family is like, and so on," said Selmer Bringsjord, head of Rensselaer's Cognitive Science Department and leader of the research project. The researchers plan to engineer, from the start, a full-blown intelligent character and converse with him in an interactive virtual environment, like Second Life.

Nerve-tapping neckband used in 'telepathic' chat

From NewScientist 

A neckband that translates thought into speech by picking up nerve signals has been used to demonstrate a "voiceless" phone call for the first time.

With careful training a person can send nerve signals to their vocal cords without making a sound. These signals are picked up by the neckband and relayed wirelessly to a computer that converts them into words spoken by a computerised voice.

Attention regulation and monitoring in meditation

Attention regulation and monitoring in meditation.

Trends Cogn Sci. 2008 Mar 6;

Authors: Lutz A, Slagter HA, Dunne JD, Davidson RJ

Meditation can be conceptualized as a family of complex emotional and attentional regulatory training regimes developed for various ends, including the cultivation of well-being and emotional balance. Among these various practices, there are two styles that are commonly studied. One style, focused attention meditation, entails the voluntary focusing of attention on a chosen object. The other style, open monitoring meditation, involves nonreactive monitoring of the content of experience from moment to moment. The potential regulatory functions of these practices on attention and emotion processes could have a long-term impact on the brain and behavior.

Action verbs and the primary motor cortex: A comparative TMS study

Action verbs and the primary motor cortex: A comparative TMS study of silent reading, frequency judgments, and motor imagery.

Neuropsychologia. 2008 Feb 2;

Authors: Tomasino B, Fink GR, Sparing R, Dafotakis M, Weiss PH

Single pulse transcranial magnetic stimulation (TMS) was applied to the hand area of the left primary motor cortex or, as a control, to the vertex (STIMULATION: TMS(M1) vs. TMS(vertex)) while right-handed volunteers silently read verbs related to hand actions. We examined three different tasks and time points for stimulation within the same experiment: subjects indicated with their left foot when they (i) had finished reading, (ii) had judged whether the corresponding movement involved a hand rotation after simulating the hand movement, and (iii) had judged whether they would frequently encounter the action verb in a newspaper (TASK: silent reading, motor imagery, and frequency judgment). Response times were compared between TMS(M1) and TMS(vertex), both applied at different time points after stimulus onset (DELAY: 150, 300, 450, 600, and 750ms). TMS(M1) differentially modulated task performance: there was a significant facilitatory effect of TMS(M1) for the imagery task only (about 88ms), with subjects responding about 10% faster (compared to TMS(vertex)). In contrast, response times for silent reading and frequency judgments were unaffected by TMS(M1). No differential effect of the time point of TMS(M1) was observed. The differential effect of TMS(M1) when subjects performed a motor imagery task (relative to performing silent reading or frequency judgments with the same set of verbs) suggests that the primary motor cortex is critically involved in processing action verbs only when subjects are simulating the corresponding movement. This task-dependent effect of hand motor cortex TMS on the processing of hand-related action verbs is discussed with respect to the notion of embodied cognition and the associationist theory.

Electrohype 2008

Via Networked Performance

electrohype.jpg

 

Electrohype 2008 will present works by 5 - 8 artists or artist groups. To give the exhibition a broad perspective we are looking for Nordic as well as international artists. Electrohype has since the start in 1999 focused on what we choose to call computer based art. Art that runs of computers and utilizes the capacity of the computer to mix various media, allow interaction with the audience, or machines interacting with each others etc. in other words art that can not be transferred to “traditional” linear media. This might seem as a narrow approach but we have discovered that it gives us a better focus on a genre that in no way is narrow.

We are not looking for “straight” video art (even if it is edited on a computer) or still images rendered on computers and other material that refers to more “traditional” media forms. Forms were the traditional tools have been replaced with computers and software.

Curators for the biennial are Anna Kindvall and Lars Gustav Midbxe.

Practical: You can submit with our online form or download the application form as PDF-file. You have to use one of these two forms to submit to our call. This can be found on this address. NOTE: Please do NOT send documentation material as attachments via e-mail. Put your material online and send us the download URL or ftp address, or send us a CD or similar in the mail. Do NOT send 8 pages CVs and only complement with enclosures if it is necessary. Please read the form and follow the guidelines. We receive a large amount of proposals and all of them are reviewed closely. To be able to do this we ask you to follow the structure in the application form and the topics mentioned above.

Financial: Due to a limited budget we will encourage everyone submitting material to look for possibilities for local funding to help cover costs for transport, travel and rent of technical equipment. This is not a requirement but a request; external funding can help us during the financial planning. The quality of the artwork will always be the determining element.

Electrohype covers all expenses, within reasonable limits, and also pays an artist honorarium to participating artists. Electrohype does not support development and production of unfinished artworks.

In previous exhibitions we have managed to keep a high level both in artistic content and exhibition design, even on a modest budget. It is therefore very important for us to avoid unpleasant surprises, so please keep this in mind when filling out the various posts in the form, especially when it comes to technical requirements, transport weight etc.

Nooron: a platform for collaboration on a global scale

From the project website 
 
Nooron is free (LGPLed) software which aims to provide a platform for collaboration on a global scale. The theory behind this effort is that a way to achieve such inclusiveness while also promoting quality is to create the mother-of-all-peer-review-systems and apply it to flexible, distributed knowledge representation. Unlike the majority of collaborative filtering systems, Nooron is based on user-extensible criteria (dimensions along which evaluations -- ratings -- may occur.) An unprecedented (except in biology) level of self-organization is expected to result from diligent application of criteria-based filtering to nearly every aspect of the system.

Improving quality of life using compound mind-body therapies

Improving quality of life using compound mind-body therapies: evaluation of a course intervention with body movement and breath therapy, guided imagery, chakra experiencing and mindfulness meditation.

Qual Life Res. 2008 Mar 7;

Authors: Fernros L, Furhoff AK, Wändell PE

Objective Assess changes in quality of life and in sense of coherence (SOC), after an intervention involving a self-development course using mind-body medicine (MBM) activities. Design A questionnaire study using a health-related quality of life (HRQOL) instrument, the SWEDQUAL, with 13 subscales and scores ranging from 0 to 100, combined with the SOC-13 scale, healthcare utilisation, medication and sick listing data. Setting A training centre for MBM. Eligible course attendants (study group, SG, n = 83) assessed their HRQOL before and 6 months after a 1-week course. A control group (CG) of individuals who had previously attended the course (n = 69), matched for age, sex and length of course time to the SG, also made assessments. Main outcome Changes in HRQOL and SOC in SG and CG. Results Of the 13 HRQOL subscales, eight showed clinically significant improvement in the SG (>9%, p < 0.01), namely, General health perceptions (9%), Emotional well-being [negative (45%) and positive (26%)], Cognitive functioning (24%), Sleep (15%), Pain (10%), Role limitation due to emotional health (22%) and Family functioning (16%). Sexual, marital and physical function and role in the SG as well as all CG scores were similar to average population values. The assessed SOC also improved in the SG after intervention (p < 0.01), challenging previous statements of 'the stableness of SOC'. Use of psychotropic medication was slightly reduced in the younger aged SG participants after intervention. Conclusions This group of men and women (SG), starting from a clinically significant low health assessment, had improved their HRQOL and SOC after the course intervention.

Blood Pressure Response to Transcendental Meditation: A Meta-analysis

Blood Pressure Response to Transcendental Meditation: A Meta-analysis.

Am J Hypertens. 2008 Mar;21(3):310-6

Authors: Anderson JW, Liu C, Kryscio RJ

BackgroundPrior clinical trials suggest that the Transcendental Meditation technique may decrease blood pressure of normotensive and hypertensive individuals but study-quality issues have been raised. This study was designed to assess effects of Transcendental Meditation on blood pressure using objective quality assessments and meta-analyses.MethodsPubMed and Cochrane databases through December 2006 and collected publications on Transcendental Meditation were searched. Randomized, controlled trials comparing blood pressure responses to the Transcendental Meditation technique with a control group were evaluated. Primary outcome measures were changes in systolic and diastolic blood pressure after practicing Transcendental Meditation or following control procedures. A specific rating system (0-20 points) was used to evaluate studies and random-effects models were used for meta-analyses.ResultsNine randomized, controlled trials met eligibility criteria. Study-quality scores ranged from low (score, 7) to high (16) with three studies of high quality (15 or 16) and three of acceptable quality (11 or 12). The random-effects meta-analysis model for systolic and diastolic blood pressure, respectively, indicated that Transcendental Meditation, compared to control, was associated with the following changes: -4.7 mm Hg (95% confidence interval (CI), -7.4 to -1.9 mm Hg) and -3.2 mm Hg (95% CI, -5.4 to -1.3 mm Hg). Subgroup analyses of hypertensive groups and high-quality studies showed similar reductions.ConclusionsThe regular practice of Transcendental Meditation may have the potential to reduce systolic and diastolic blood pressure by approximately 4.7 and 3.2 mm Hg, respectively. These are clinically meaningful changes.American Journal of Hypertension (2008) doi:10.1038/ajh.2007.65American Journal of Hypertension (2008) doi:10.1038/ajh.2007.65.

Kinesthetic Imagery and Tool-Specific Modulation of Corticospinal Representations in Expert Tennis Players

Kinesthetic Imagery and Tool-Specific Modulation of Corticospinal Representations in Expert Tennis Players.

Cereb Cortex. 2008 Feb 21;

Authors: Fourkas AD, Bonavolontà V, Avenanti A, Aglioti SM

Specific physical or mental practice may induce short- and long-term neuroplastic changes in the motor system and cause tools to become part of one's own body representation. Athletes who use tools as part of their practice may be an excellent model for assessing the neural correlates of possible bodily representation changes that are specific to extensive practice. We used single-pulse transcranial magnetic stimulation to measure corticospinal excitability in forearm and hand muscles of expert tennis players and novices although they mentally practiced a tennis forehand, table tennis forehand, and a golf drive. The muscles of expert tennis players showed increased corticospinal facilitation during motor imagery of tennis but not golf or table tennis. Novices, although athletes, were not modulated across sports. Subjective reports indicated that only in the tennis imagery condition did experts differ from novices in the ability to form proprioceptive images and to consider the tool as an extension of the hand. Neurophysiological and subjective data converge to suggest a key role of long-term experience in modulating sensorimotor body representations during mental simulation of sports.

Clinical Assessment of Motor Imagery After Stroke

Clinical Assessment of Motor Imagery After Stroke.

Neurorehabil Neural Repair. 2008 Mar 6;

Authors: Malouin F, Richards C, Durand A, Doyon J

OBJECTIVE: The aim of this study was to investigate: (1) the effects of a stroke on motor imagery vividness as measured by the Kinesthetic and Visual Imagery Questionnaire (KVIQ-20); (2) the influence of the lesion side; and (3) the symmetry of motor imagery. METHODS: Thirty-two persons who had sustained a stroke, in the right (n = 19) or left (n = 13) cerebral hemisphere, and 32 age-matched healthy persons participated. The KVIQ-20 assesses on a 5-point ordinal scale the clarity of the image (visual scale) and the intensity of the sensations (kinesthetic scale) that the subjects are able to imagine from the first-person perspective. RESULTS: In both groups, the visual scores were higher (P = .0001) than the kinesthetic scores and there was no group difference. Likewise, visual scores remained higher than kinesthetic scores irrespective of the lesion side. The visual scores poststroke were higher (P = .001) when imagining upper limb movements on the unaffected side than those on the affected side. When focusing on the lower limb only, however, the kinesthetic scores were higher (P = .001) when imagining movements of the unaffected compared to those on the affected side. CONCLUSIONS: The vividness of motor imagery poststroke remains similar to that of age-matched healthy persons and is not affected by the side of the lesion. However, after stroke motor imagery is not symmetrical and motor imagery vividness is better when imagining movements on the unaffected than on the affected side, indicating an overestimation possibly related to a hemispheric imbalance or a recalibration of motor imagery perception.
