    Tsukuba Walking System

    Published at 18:22   Category VR Devices  

    Just when I said nothing interesting was happening it seems lots of things are spawning !

    From NewLaunches :

    University of Tsukuba Japan has developed a dome shaped virtual reality walking system for patients patients suffering from a stroke etc. The VR treadmill can accommodate a 80kg person for a walking speed 1m/sec with strides of 80 cms. The dome has a viewing angle of 270 degrees horizontally and a 60 degrees vertically. The system is not fully developed and is very expensive for hospitals to install. 

    I’m not sure why a simple treadmill is not enough.

    And is this curved screen cheaper and/or more suitable (including development of hard&soft) than a Sensics HMD or a Crescent HMD or a Fakespace  Wide5 HMD (of which I haven’t talked yet but it really rocks!) ?

    There must be good reasons, please tell me =)

    Design, prototyping

     

    Car, aircraft, boat, tractors, household appliances manufacturers, and even factory planners are using VR to prototype their products. They can create interactive virtual prototypes for far less money and time than a real prototype.

    This has a lot of advantages. Products or work environments are tested in VR, potentially with the end user, and problems are identified early in the design process. Once these virtual prototypes are built, all the actors, engineers, designers, ergonomists, marketing and end users, can communicate around the project in a more efficient and sexy way than traditional forms like paper or movies.

    “The number of expensive, physical models and prototypes can be radically reduced by CAVE, and this ultimately saves a lot of time and money”, says Andreas Enslin, Miele’s senior designer. (…)

    “CAVE creates a quite different form of communication and cooperation. Marketers, designers and engineers can now deal with one issue simultaneously. Regardless of what comes up with me as a designer or engineer, I am able to immediately try it and see if it works. As everyone is seeing the same thing, those people who are not directly involved in the process of development and construction can also immediately see the consequences and effects of decisions.“ (…)

    The speed gained is also expected to increase the willingness to experiment, Miele’s senior designer believes. “In this respect, our innovative strength will also increase. It has become much easier to try out something crazy in between.”

    From the article : “Carmaker embraces VR“, New Zealand Herald :

    “We can understand it from a person’s perspectives, rather than what analytical tools tell us,” says Elizabeth Baron, an advanced visualisation technical specialist who carried out Ford’s virtual reality programme. (…)

    Four years ago, the carmaker would have spent four to 10 weeks building prototypes each time engineers wanted to experience a different beltline height, Schiavone said.

    But the Programmable Vehicle Model at the Immersive Virtual Reality - or iVR - lab can simulate the change at the touch of a button.”

    Marketing

    VR is also used for marketing and pre-sales: potential clients can now test the product before it’s even finished, and be implied in the choice of configurations. For example you can take a walk in your future plane, and interactively place seats where you want. Even better, the system will make sure your decisions comply with security norms.

    (c) Virtools

    Procter&Gamble and Kimberly Clark are using VR to create, in every detail, virtual stores to conduct marketing studies about product packaging, store layout and displays. With eye-tracking technologies, they can see precisely what aspect of their configuration influences your shopping experience and purchasing decisions.

    Training

    One of the most fascinating aspects of VR is its ability to train people. A lot of companies and administrations are using VR to train their staff to complicated and/or dangerous procedures.

    VR allows you to really perform the gestures, thus what you learn in the virtual environment is directly applicable to real life situations. Pilots get their flight certifications for some planes without ever flying this particular plane!

    It also allows you to to test different scenarios instantly, review errors in slow motion and from different viewpoints, restart as many times as needed. Learning in such a simulator is a lot more efficient, and people are much more willing to take the training; the trainee is active in the simulator and acting alone as he would in real life, when before he was passive with other trainees, watching the teacher do the procedure or looking at photos on a CD.

    A recent article in the Nature magazine even suggests that VR medical training should be mandatory : “This approach has great potential to allow inexperienced physicians to acquire meaningful new procedural skills…without jeopardizing patient safety in the process”.

    Data Visualization

    One of the oldest applications of VR, along with flight simulators, is data visualization. Mainly used in the oil and gas industry to study geological data and find new energy sources.

    Architecture

    VR allows the architects, engineers and clients to design a building, to valorize a project by showing it to a large audience, convince all actors, and do the maintainance of building. It also allows citizens to visualize and give their opinion about a project in their neighborhood.

    Scientific, medical and research

    VR is particularly suited to study the human being. It allows the manipulation of a reality that is close enough to ours and conduct research on cognition, perception and psychology, that would not be practical or ethical to perform in real life (see the Virtual reprise of Milgram’s obedience experiments). Moreover you can reproduce the exact same environment conditions indefinitely.

    Virtual Reality for therapeutical needs is a field that is also rapidly developping. Better therapies through VR are studied for speech therapy, physical therapy (video), some therapy for autistic children, motor rehabilitation after a stroke, even smoking, gambling, drugs and alcohol addictions ! And new areas are being explored everyday.

    It is also a very good tool to treat phobias in a controlled environment through exposure therapy. The subject can be immersed in a virtual world on a high bridge to treat fear of heights, or in a room with virtual spiders, or in the middle of a war to treat post-traumatic syndrome disorder (Agoraphobia, Virtual therapy video, PTSD for 9/11, “Virtual Reality used to fight phobias“, “Paranoia Study“).

    Entertainment

     

    Despite what you may think, VR games seem to have practically disappeared. I haven’t seen any recent commercial attraction. The best VR games so far seem to be done by enthusiasts: Cave Quake 3 by Paul Rajlich, Cave Unreal Tournament by Jeffrey Jacobson, and Atrium Experience by Alexandre Bouchet and Lionel Dominjon. (Oh and Atrium will be shipped with Virtools/VR Library 2.5 ;)

    AFRV - 2nd days

    Published at 17:42   Category Virtual Reality  

    The french association for virtual reality (AFRV [fr], english page here) was holding its annual meeting in Marseille. Nearly all the major actors of VR in France were there.

    The complete photo gallery is here.

    - The 3×3x4m Cave of the CRVM -

    Bruno Arnaldi has been elected as the new AFRV president, replacing Philippe Fuchs.

    Here are some interesting things that were said during those days, in a simplified and out-of-context form (don’t hesitate to correct me!) :

    - VR is very interesting to study humans: it allows for a good experimental control and ecological validity: you can manipulate a reality and conduct experiments that for practical or ethical reasons couldn’t be conducted in the real world.

    - In a lot of fields, studies must be done to see if the actions, behavior and perception in virtual environments and reality match. This ecological validity is crucial for the validity of studies conducted in VR only.

    - A lot of work has to be done to improve the communication skills of an avatar: non-verbal cues must be transmitted for better communication, and the way we interact with them must be simplified, more natural.
    - A lot of people don’t want to use intrusive devices (HMDs, glasses etc)

    - 3D interactions are still a big research area.

    - Users are not necessarily ready to use haptics (force-feedback), even a 6DOF device is sometimes difficult!

    - Rehabilitation through VR is better: closer to reality, better transfer from virtual to real, better motivation thanks to the fun aspect of VR.

    - Stereo viewing is not the natural way of seeing. Sometimes we are faster at evaluating depth through parallax. Studies are being conducted to study the perception of shapes with stereoscopy compared to the real world.

    Designing VR Exposure Therapy Simulations for Post-Traumatic Stress Disorders

    Published at 9:43   Category VR Applications  

    Here’s an article on Serious Game Source by Ari Hollander from Imprint talking about how VR can help therapists :

    “Virtual reality (VR) provides a tool that can allow therapists to gradually intensify a simulation of the traumatic events rather than relying on pure talk and storytelling. (..) At Imprint Interactive, we have been involved with a number of PTSD VR exposure therapy research projects (..)

    These include a simulation of the tragic events of 9/11/01, a simulation of a terrorist bus bombing for a research group at the University of Haifa in Israel, and two simulations for treating U.S. soldiers returning from Middle East conflict. (..)

    This is a familiar goal in both game design and VR. In game design we call the engagement process “fun” (..) . In VR we call the engagement process presence.

    The (..) goal is to make the environment sufficiently reminiscent of the patient’s experience that it evokes memories of the traumatic events.

    These applications include functionality that allows therapists to dynamically control the intensity of the experience for the patient, increasing or decreasing the level of stimulation and tension according to the level of anxiety.

    Design Guidelines

    Our job as virtual environment designers is to seek the sweet spot on the suspension of disbelief curve and avoid wasting resources that would only be dumped into the Uncanny Valley. In the case of VR Exposure Therapy applications I would suggest that the metaphor does double-duty and can also inform our selection of appropriate content to achieve reminiscence: we seek the sweet spot on the curve where we have included sufficient contextual details to evoke responses from a wide variety of patients without adding too much specific information that could distract from some patients’ experiences. (..)

    - Favor the suggestive over the specific. (..)
    - Use intentional ambiguity to cover a range of possible scenarios. (..)
    - Use systemic designs and parallel information to specify and disambiguate. (..)

    More than one researcher has reported that VR Exposure therapy patients, when recalling their therapy experiences, have occasionally described significant components of their experience in VR that were not actually present in the simulation!”

    Virtual Therapy to quit smoking

    Published at 0:30   Category VR Applications  

    This article (and video) at TechEBlog talks about a virtual therapy where patients are immersed in a virtual world filled with ’smoking triggers’ to help them fight the will to light a cigarette.
