On the fly 3D surface reconstruction: KinectFusion

Microsoft’s Kinect is rightfully getting a lot of attention from researchers. One snippet that caught my attention is a collaboration between Microsoft and a number of UK and Canada-based researchers. The result is KinectFusion.

Have a look for yourself:

The implications for virtual worlds are fairly obvious. The thing that particularly struck me is the dynamic capability of the approach even at this early stage – if something changes with the physical world environment, it is reflected virtually. For the education, science and health fields, to name three, this is huge.

One obvious example within my pet area of clinical simulation: a camera (with consent) is placed in a busy emergency department in a large teaching hospital. Emergency nursing students based at a rural university receive that feed, had it convert on the fly to 3D for use within their virtual learning environment. Students may actually ‘work’ a full shift virtually, needing to respond to the challenges of the changing environment as they occur.

As I said, there’s a long way to go (for starters, KinectFusion is about surfaces only), but the progress is rapid and exciting. Over to you: what applications could you see this being good for?

Emergency birth at home simulation

This article originally appeared over at our sister-site Metaverse Health.

One of the biggest challenges with online or PC-based simulations is the infrastructure required to run them. The move to web-based simulations is key to resolving that issue although web-based currently can come with a trade-off on complexity in a lot of cases.

That said, sometimes simplicity can still cover key concepts and that’s evident with a nice little simulation developed by the Engender Game Group at the University of Wisconsin-Whitewater.

It provides a home-based scenario where a woman needs support through delivering her baby. It covers everything from the initial meeting through to initial post-natal care until medical assistance arrives. Have a go for yourself.

For the record I’ve confirmed the validity of my choice not to become a midwife, as I got barely more than half the questions in the scenario correct!

Unlimited Detail: simulation implications

I ran across a fascinating video via New World Notes, that shows an alternate way of rendering 3D environments. The seven-minute video provides a fascinating (albeit hyperbole-filled) overview of the atom-based approach, called Unlimited Detail.

The driving force behind the project is Queensland, Australia-based Bruce Dell, working for an outfit called Euclideon (whose website is unavailable strangely).

Before I go on any further, you should have a look at the video yourself:

One more external pointer: Popsci covers the issue well, but it’s worth reading the comments on that article to pick up on some of the scepticism around about Unlimited Detail.

Of course, whether Unlimited Detail is a near reality or a pipe dream is partly a moot point: it still raises some interesting points for me on how enhancing the current approach to graphical detail is pivotal to the success of 3D environments in a range of areas, including my pet topic of clinical simulation. Until there’s the ability to replicate complex behaviours or procedures in a graphically realistic way, true simulation will remain problematic in these environments.

Let’s take even a ‘simple’ procedural simulation like inserting an endotracheal tube (ETT). The need for graphical reality is critical if any attempt is to be made to translate the practice to the physical world environment – the state of the ‘patient’, their position on the bed, the anatomical correctness of their trachea, the flexibility of the tube and so on. That;s why I’m encouraged by developments like Unlimited Detail.

Of course the real test is whether it sees the light of day in environments accessible to the general public.

Disability Rights Conference in Second Life

Another great event from Virtual Ability Island in Second Life on the way in coming days:

July 16, 2011 – IDRAC2011

International Disability Rights Affirmation Conference- July 23/24, 2011

Virtual World Conference about Real World Rights

Virtual Ability, Inc. announces the International Disability Rights Affirmation Conference (IDRAC2011) to be held Saturday and Sunday, July 23/24, in Second Life®.

In 2006, the United Nations held a Convention on the Rights of Persons with Disabilities. The text of the Convention was adopted by the UN General Assembly, and now has over 100 signatory states, including the US and the European Union.

Legislation to protect the rights of persons with disabilities is becoming common around the world. However, the June 9 World Health Organization study, the World Report on Disability, found significant barriers to equal access for persons with disabilities still exist.

This international conference will begin to explore legal protections around the world for persons with disabilities. Featured panels of persons from around the world will discuss local legislation that supports the rights of persons with disabilities. Panelists come from Australia, Belgium, Costa Rica, Italy, the Netherlands, Spain, and the UK.

Featured presenters include Scott Gill, Simon Walsh, Sister Abeyante, and Roberta Walker Kilkenny.

Gill is Executive Director of Access 2 independence, a Center for Independent Living in Iowa, US; he will talk about the independence movement. Walsh is head of his own consulting firm in the UK; he will compare the US ADA legislation with the UK’s DDA. Abeyante is a Salvatorian Sister; she will discuss advocacy for disability (civil and human) rights. Kilkenny is a college instructor; she will present about the significance of the UN Convention.

Presentations by the National Service Inclusion Project and the Job Accommodation Network will highlight disability services available in the US. Other sessions will feature peer support, comedy, and dance, both as part of the affirmation celebration.

Presentations will take place in Sojourner Auditorium on Virtual Ability Island within Second Life®: http://maps.secondlife.com/secondlife/Virtual%20Ability/54/170/23. The full schedule of confirmed presenters is posted inworld, and at http://virtualability.org/IDRAC2011.aspx.

Alice Krueger, president of Virtual Ability, Inc., stated: “It is a great pleasure to host so many wonderful speakers. Our audience will gain information about the extent of the issues facing people with disabilities, and the potentials for solutions to barriers.”

Virtual Worlds and Metaverse Platforms: New Communication and Identity Paradigms

Just a quick note that the book chapter on virtual worlds, health and simulation I wrote during late 2010 is now available for ordering as part of the book Virtual Worlds and Metaverse Platforms: New Communication and Identity Paradigms

Each chapter has an abstract available for viewing and a PDF sample of the first couple of pages (here’s my PDF sample). There’s an interesting range of topics on offer and I’m looking forward to having a read of them all. As my first academic publication I’m just a little stoked ;)

It’s also interesting to note I’m the only author that’s not directly aligned with a University – is it really that rare for someone to contribute to an academic publication that’s not directly aligned with a tertiary institution?

Of course, with the rapidity of change in the field, books like this can date rapidly but having a read-through my own chapter I think it holds up relatively well so far – that may be a different story in six months!

If you do end up reading the chapter in full, I’d dearly love your feedback on it – I have no doubt I’ve missed stuff given the breadth of things underway.

Emotion transference: Telenoid

This story appeared earlier this week over at sister-site Metaverse Health.

As a clinician fascinated by the use of new technologies to achieve outcomes, it’s hard to go past anything that is looking at bridging the divide between human emotions / touch and technology. Telenoid is one such project. It’s aim is to provide an effective way to transfer people’s presence.

The research on telepresence is booming and it’s fairly widely accepted that videoconferencing is superior to teleconferencing and that platforms like virtual worlds provide even better telepresence sometimes. Telenoid is a step further again, providing a tangible means of interacting with someone remotely. In the second video below you’ll see its creator citing a key inspiration was the ability for remotely located grandparents to interact more with their grandchildren. That alone is laudable but for me the clinical simulation potentials stood out pretty strongly.

Real patients as simulation

Imagine the ability to have a ‘patient’ reflecting the emotions and speech of a real person in combination with the current simulation functionality i.e. feedback, monitoring of biometric data etc. Taken a step further: a real patient experiencing a real health issue is able (with consent of course) to have their experience transferred to a simulation exercise in real time. There are already consumer devices on the market able to control avatars via thought processes, this is only a small step beyond that.

A specific example:

a. Marjorie is a patient with bowel cancer who is scheduled to have chemotherapy.

b. She consents to her next outpatient chemotherapy session being used for simulation purposes with third-year nursing students at a local university.

c. On arrival at the clinic for her chemotherapy, Marjorie agrees to wear a discreet headset that both captures her emotions as well as her voice as she goes through the process.

d. At the university the students are in a laboratory environment set up for chemotherapy and the simulation mannikin is reflecting Marjorie’s experience as students use the same clinical pathway as the clinic to simulate providing the chemotherapy. The voice recorder allows the students to hear what the nurse is actually doing for Marjorie, providing the opportunity to contrast practice and to ‘see’ what impact that practice is having on Marjorie.

It sounds a little clunky and requires tight integration betwen education and practice, but the potential is there. Using dementia as an another example (although this is where consent can be fraught with difficulties): imagine the power of a mannikin that spoke and reflected the emotions and movements of an individual with severe dementia. The learning potential is enormous and would have the subsequent benefit of much more confident and confident new practitioners.

Videos

The first video shows a conversation with Telenoid:

This one shows Telenoid up closer and note how easily people interact with it:

Thanks to Meg over at Future of Sex for the heads-up. Yes, the potential for this technology in regards to sex is likely to be the driver for its further enhancement and adoption. Who’d of thought?
