Engineers and computer scientists at West Virginia University's GeoVirtual Laboratory (GVL) have developed what they called the VRGIS solution - short for 'virtual reality geographic information systems.' The VRGIS project combines several technologies, such as virtual reality (VR), location based services (LBS), and geographic information systems (GIS) with 'the power of the Internet to provide people with a portal to dynamically share information in a revolutionary new way.'

Robert Kirsch and coll., researchers at the at Louis Stokes Veterans Affairs Medical Center, are developing a more intuitive way for severely paralyzed individuals to regain motor function:

Scientists are now building a device that records brain signals and transmits them to paralyzed muscles, potentially returning muscle control to severely paralyzed patients. In the prosthetic system, which is still in early development, a brain chip records neural signals from the part of the brain that controls movement. The chip then processes those signals, sending precise messages to wires implanted in different muscles of the patient's arm or hand, triggering the paralyzed limb to grab a glass or scratch the nose. "Our ultimate goal is for a person to think and effortlessly move the arm ," says Robert Kirsch , associate director of the Functional Electrical Stimulation Center, at Louis Stokes Veterans Affairs Medical Center, in Cleveland, OH.

But for some patients, especially severely paralyzed individuals with control over few muscles, using signals recorded directly from the brain to control the paralyzed limbs could provide an easier and more intuitive way to move. So the Cleveland researchers are working with John Donoghue , a neuroscientist at Brown University, who has developed implantable brain chips that record and process electrical activity directly from neurons. The device, made by Cyberkinetics Neurotechnology Systems , in Foxborough, MA, consists of a tiny chip containing 100 electrodes that record signals from hundreds of neurons in the motor cortex, the part of the brain that modulates movement. A computer algorithm then translates this complex pattern of activity into a signal used to control a computer or prosthetic limb.

The project is likely to be complex. Donoghue and colleagues must first make their brain chip wireless and fully implantable. (Currently, patients have some hardware protruding from their skull and are connected to a computer via wires.) An implantable system would minimize the risk of infection, and it might also help patients learn to use the system. Eberhard Fetz , a neuroscientist at the University of Washington, in Seattle, who is developing similar systems in monkeys, says that an implantable device would allow patients to use the system 24 hours a day, which would help them learn to modulate neural signals for precise control.

oh, that's brilliant! 

For many people, exercise is simply boring, so they turn to devices that can help them keep their minds off what they’re doing while they exercise. Entertainment fitness uses technology to engage users rather than distract them.

Tetris Weightlifting is a prototype entertainment fitness system that allows players to lift weights as the means of control for a modified version of Tetris. User testing with the device suggests great potential for combining casual games with exercise activity.

Presence: a unique characteristic in educational virtual environments

Virtual Reality Journal, Volume 10, Number 3-4 / December, 2006, Pages 197-206.

Author: Tassos A. Mikropoulos

This article investigates the effect of presence on learning outcomes in educational virtual environments (EVEs) in a sample of 60 pupils aged between 11 and 13 years. We study the effect of personal presence, social presence and participant’s involvement on certain learning outcomes. We also investigate if the combination of the participant’s representation model in the virtual environment (VE) with the way it is presented gives a higher sense of presence that contributes to learning outcomes. Our results show that the existence of an avatar as the pupils’ representation enhanced presence and helped them to successfully perform their learning tasks. The pupils had a high sense of presence for both cases of the EVE presentation, projection on a wall and through a head mounted display (HMD). Our socialized virtual environment seems to play an important role in learning outcomes. The pupils had a higher sense of presence and completed their learning tasks more easily and successfully in the case of their egocentric representation model using the HMD.

Virtual reality, telemedicine, web and data processing innovations in medical and psychiatric education and clinical care.

Acad Psychiatry. 2006;30(6):528-33

Authors: Hilty DM, Alverson DC, Alpert JE, Tong L, Sagduyu K, Boland RJ, Mostaghimi A, Leamon ML, Fidler D, Yellowlees PM

OBJECTIVE: This article highlights technology innovations in psychiatric and medical education, including applications from other fields. METHOD: The authors review the literature and poll educators and informatics faculty for novel programs relevant to psychiatric education. RESULTS: The introduction of new technologies requires skill at implementation and evaluation to assess the pros and cons. There is a significant body of literature regarding virtual reality and simulation, including assessment of outcomes, but other innovations are not well studied. CONCLUSIONS: Innovations, like other uses of technology, require collaboration between parties and integration within the educational framework of an institution.

Education about hallucinations using an internet virtual reality system: a qualitative survey.

Acad Psychiatry. 2006;30(6):534-9

Authors: Yellowlees PM, Cook JN

OBJECTIVE: The authors evaluate an Internet virtual reality technology as an education tool about the hallucinations of psychosis. METHOD: This is a pilot project using Second Life, an Internet-based virtual reality system, in which a virtual reality environment was constructed to simulate the auditory and visual hallucinations of two patients with schizophrenia. Eight hundred sixty-three self-referred users took a self-guided tour. RESULTS: Five hundred seventy-nine (69%) of the users who toured the environment completed a survey. Of the survey responders, 440 (76%) thought the environment improved their understanding of auditory hallucinations, 69% thought it improved their understanding of visual hallucinations, and 82% said they would recommend the environment to a friend. CONCLUSIONS: Computer simulations of the perceptual phenomena of psychiatric illness are feasible with existing personal computer technology. Integration of the evaluation survey into the environment itself was possible. The use of Internet-connected graphics environments holds promise for public education about mental illness.

A browser called 3B that allows you take existing 2D Web content and make an avatarized 3D space out of it that others can visit. From the site:

“3B allows you take any web sites or photos and place them in a personalized 3D space, your 3B village. You can use MySpace, Hi5 or Bebo pages or photos you’ve loaded onto Flickr, Photobucket or any other web service.”

From the project's website (via 3D point):

The Ogoglio project is exploring shared online worlds in the context of web enabled work. If World of Warcraft is "the new golf", then we're exploring "the new business district".

We are creating spaces where people will meet with remote coworkers, collaborate using new tools, integrate existing business applications, and enjoy the benefits of being in the same office with people in different time zones.

Project summary:

Many people now start their careers with a deep understanding of cooperative 3D communities like World of Warcraft, but when they enter the workplace they are handed email and a shared calendar and are expected to teach themselves how to be productive. Instead of forcing people to limit their communication to these thin channels, The Ogoglio project will provide community workspaces with the planning and coordination tools which have proven to be effective in multiplayer online games.

Rhythms of social interaction: messaging within a massive online network (PDF) by Scott Golder, Dennis Wilkinson, and Bernardo Huberman:

"We have analyzed the fully-anonymized headers of 362 million messages exchanged by 4.2 million users of Facebook, an online social network of college students, during a 26 month interval. The data reveal a number of strong daily and weekly regularities which provide insights into the time use of college students and their social lives, including seasonal variations. We also examined how factors such as school affiliation and informal online “friend” lists affect the observed behavior and temporal patterns. Finally, we show that Facebook users appear to be clustered by school with respect to their temporal messaging patterns.

Instant messaging programs connect people across the Internet. Newer programs like RadiusIM and Meetro, connect people by their real-world location. RadiusIM is an AJAX application, while Meetro is a downloadable client. Both allow you to fill out your location and profile as a way to meet new people in your area, or even another country. Unlike the other developments in chat, location based IM hasn’t seen heavy adoption on other platforms, which continue to connect people based on a user generated buddy list.

National LambdaRail (NLR) announced today that it is developing a plan to implement a Telepresence testbed based on the Cisco Telepresence Meeting solution by mid-2007. With its nationwide optical backbone connected to nearly 20 regional optical networks, it will be simple for researchers to participate in the testbed from key research and education facilities throughout the nation. A call for participation will be issued early next year.
