    Laval Virtual 2007

    Published at 11:17   Category Game, VR Applications, VR Devices, VR Displays, Virtual Reality, Virtual Reality DIY  

    These three great days have been very intense; holding the booth, meeting people, attending conferences, trying hardware and applications, being a jury member for the student competition. First things first, here are some pictures I took there. I should have taken more of the show..

    There was not much new hardware, especially hardly any new expensive hardware. The novelty came from the use of existing hardware and better software. It seems that VR is at last being democratized; people create customized and cheap input devices, use webcams, recycle hardware not meant for VR etc.

    GCC – No newline at end of file

    Published at 15:09   Category C++  

    Just a small post to understand why GCC complains that there is “No newline at end of file” :

    > What is the rationale for this warning ? What can break or is it a
    > standards thing ?
    Imagine foo.h:
    blah blah blah
    Now bar.c:
    #include "foo.h"
    #include "grill.h"
    Now imagine a preprocessor that isn't smart enough to put
    the newline in for you...
    blah blah blah#include "grill.h"
    It may not include grill.h.

    That’s obvious but I never thought about it =)

    VR Medical training should be mandatory

    Published at 8:50   Category VR Applications  

    Here’s an interesting article from Nature about the advantages on using VR for surgery training, but also for procedures standardisation :

    Virtual surgery could soon be a realityVirtual reality (VR) simulators should be used to teach doctors new skills, a leading cardiologist has advised, in the April edition of Nature Clinical Practice Cardiovascular Medicine.

    “This approach has great potential to allow inexperienced physicians to acquire meaningful new procedural skills…without jeopardizing patient safety in the process,” writes Christopher Cates, Director of Vascular Intervention at the Emory Hospitals in Atlanta.

    Dr. Cates believes that VR could one day become a mandatory component of procedural training for physicians. Recently returned from an international conference in Rio de Janeiro, where he and others conducted a symposium on the use of VR training, he described the current technology as “very impressive”.

    “With a simulator you can measure every minute movement in the virtual anatomy. You can see whether the person’s scraping or pushing too hard as he’s turning the catheter, and whether he’s doing the sequence in the exact right order.”

    As well as so-called ‘mission rehearsal’, in which doctors can practice procedures on a reconstruction of an actual patient’s anatomy, VR technology also provides the potential to rate surgical skill on a real scale.

    “A lot of doctors talk a good game—they are knowledgeable but they can’t technically implement the procedure very well,” said Dr. Cates. This VR simulation can actually measure the performance of a physician. In future, to be certified for a procedure, you could have to spend a certain amount of time on a simulator to prove that you are proficient in the technique.

    “There is also real potential to create a worldwide training standard, where it doesn’t matter if you’re in Beijing, Sidney or Kuala Lumpur—the doctor is the same quality and has been trained by the same system,” he added.

    VR simulation training has already begun for carotid stenting—a procedure to increase blood flow in the carotid arteries, which supply the head and neck. Three major symposia have already taken place in the US. The first group completed the final tier of the program towards the end of last year, all achieving proficiency that was comparable with the experts.

    If the program continues to be successful, other procedures could soon be rehearsed in a similar fashion.

    “In my opinion, this will forever change the way we train for medical procedures,” concluded Dr. Cates.
