Via Networked Performance

Solipsis is a pure peer-to-peer system for a massively shared virtual world. There are no central servers at all: it only relies on end-users' machines. Solipsis is a public virtual territory. The world is initially empty and only users will fill it by creating and running entities. No pre-existing cities, inhabitants nor scenario to respect...Solipsis is open-source, so everybody can enhance the protocols and the algorithms. Moreover, the system architecture clearly separates the different tasks, so that peer-to-peer hackers as well as multimedia geeks can find a good place to have fun here! Current versions of Solipsis give the opportunity to act as pionneers in a pre-cambrian world. You only have a 2D representation of the virtual world and some basic tools devoted to communications and interactions

LX 2.0: Contemporary Online Experiments: NeuroZappingFolks is a non-linear zapping through the Internet, a path leading to the inside of a web of relations, a web that can be explored from one tag to a site, to another tag, to another site... from word to image to word to image. NeuroZappingFolks is then the simulation of a brain lost in the web (lost between servers, but also lost in Internet's double identity: word and image).

Jean Baudrillard, a French philosopher and social theorist known for his provocative commentaries on consumerism, excess and what he said was the disappearance of reality, died Tuesday, his publishing house said. He was 77.

Baudrillard died at his home in Paris after a long illness, said Michel Delorme, of the Galilee publishing house. The two men had worked together since 1977, when "Oublier Foucault" (Forget Foucault) was published, one of about 30 books by Baudrillard, Delorme said by telephone.

Among his last published books was "Cool Memories V," in 2005. Baudrillard, a sociologist by training, is perhaps best known for his concepts of "hyperreality" and "simulation."

Impaired Short-term Motor Learning in Multiple Sclerosis: Evidence From Virtual Reality.

OBJECTIVE: . Virtual reality (VR) has been proposed as a potentially useful tool for motor assessment and rehabilitation. The objective of this study was to investigate the usefulness of VR in the assessment of short-term motor learning in multiple sclerosis (MS). METHODS: . Twelve right-handed MS patients and 12 control individuals performed a motor-tracking task with their right upper limb, following the trajectory of an object projected on a screen along with online visual feedback on hand position from a sensor on the index finger. A pretraining test (3 trials), a training phase (12 trials), and a posttraining test (3 trials) were administered. Distances between performed and required trajectory were computed. RESULTS: . Both groups performed worse in depth planes compared to the frontal (x,z) plane (P <.006). MS patients performed worse than control individuals in the frontal plane at both evaluations (P <.015), whereas they had lower percent posttraining improvement in the depth planes only (P =.03). CONCLUSIONS: . The authors' VR system detected impaired motor learning in MS patients, especially for task features requiring a complex integration of sensory information (movement in the depth planes). These findings stress the need for careful customization of rehabilitation strategies, which must take into account the patients' motor, sensory, and cognitive limitations.

Nokia wants to superimpose digital information on the real world using a smart cell phone.

A prototype uses a GPS sensor, a compass, and accelerometers. Using data from these sensors, the phone can calculate the location of just about any object its camera is aimed at:
