The Nov 2008 sales figure for video games has just been released and it is closed to 3 billion dollars in US alone! Truly amazing! I guess people are trying to escape from the stressful real world by engaging in virtual worlds. Perhaps the video game industry can bail out the rest of the industries…

But what’s really interesting (to me) is their flight training analysis software… of course we are talking about AAR here. As always, I failed to understand why the instructional technology folks are simply NOT getting this. Isn’t this kind of training and analysis important to our field? I do believe it was what started or field… but then somewhere in the past, a folk in the road appeared, and people have been travelling down the other path.

Oh, well, you can’t win them all.

This is primarily a software to support clinical trials in which the endpoint is binary or time-to-event (TTE).

I have already come across various time-stamping methods, and the most closely “sounding” one may be time-series analysis. However, after considerable search into the method, it turned out to be closer to financial analysis (as in moving averages) than what I am hoping for. No go…

Then, I came across some literature on time-to-event analysis… (as in this BMJ article). I think I have found the right thing. (Mike seemed to think so, too.)

Second Health is located in the SciLands, a specialised region of Second Life for Science, Technology and Educational applications. Most of these projects are about professional and patient education, collaboration and health strategy.

This is an experimental, innovative and efficient means of communicating complex healthcare messages as well as illustrating what healthcare of the future could look like.

The design of the virtual hospital in Second Health is based on the principles and recommendations outlined in the recently published Healthcare for London: A Framework for Action.

“The StreamGraph shows the usage over time for the words most highly associated with the search word. One of these series together with a time period are in a selected state and coloured red. The tweets that contain this word in the given time period are shown below the graph. You can click on another word series or time period to see different matches. In the match list you click on any word to create a different graph with tweets containing that word. You can also click on the user or comment icons and any URL to see the appropriate content in another window. If you see a large spike in one time period that hides the detail in all the other periods it will be useful to click in the area to the left of the y-axis in order to change the vertical scale.”

IBM has quite a bit of resources in Serious Games, if one know where to look.

• Games solutions and interactive entertainment solutions
• Games and Interactive Entertainment e-Kit
• Online Game Prototype [pdf]
• On 3D Internet and Virtual World
• IBM is also working with Brandeis International Business School (IBS) to pilot test “Innov8″ – a serious game geared to teach young MBA and IT students and professionals how to compete in business, bridge gaps between business and IT teams. The interactive, 3-D game has the look and feel of a video game, but corresponds with non game events such as business operations. [news]

Sony Computer Entertainment America’s”LittleBigPlanet” game, released in North America on Tuesday, lets players create characters and scenarios for the PlayStation 3, taking the Internet’s embrace of community-created sites to video games.

The new game has 50 levels of play in a universe of castles and mountains where customizable sackcloth puppets must navigate obstacles and puzzles to proceed.

What separates it from the pack is a suite of tools, which allows players to create their own game challenges and share them with others online via Sony Corp’s PlayStation Network…

“The three pillars of the game are equal: play, create, and share,” said Ettouney, who co-founded the game’s development studio, Media Molecule.

Electronic Arts Inc has proven that empowering gamers is a good business decision these days. Gamers have populated the new “Spore” universe with over 25 million creatures, vehicles and buildings of their own creation. “Spore” PC and Nintendo DS games sold over 1 million copies worldwide in the first three weeks.

Billy Pidgeon, video game analyst for IDC, believes “LittleBigPlanet” will help Sony drive sales of its PS3. The PS3 lags Microsoft’s Xbox 360 and Nintendo’s Wii in total sales, but new games made by Sony exclusively for its machine may help it gain ground….

I know CAVE is considered to be an older-technology; but you never know. One of these days it may just come back. [ref: Pape, D.; Anstey, J.; Dolinsky, M.; and Dambik, E.J. (Aug, 2003).

VR Lab (Ygdrasil)

Ben Chang has a Ygdrasil User Guide on his website:

Ygdrasil is a simple scripting language for creating interactive, immersive environments in virtual reality. It is used specifically for creating virtual worlds in the CAVE, and is designed to be easy enough to use that even beginning programmers can pick it up quickly. Ygdrasil is particularly useful for artists, who can use it to create interactive VR artworks without advanced training in computer programming, or support from specialized engineers. Ygdrasil is used in CAVE’s worldwide, and can be used on a range of other kinds of VR systems or even just on a regular desktop PC.

Ygdrasil gets its name from the Tree of Life in Norse mythology and is often affectionately referred to as “Yg”. Ygdrasil was written by Dave Pape at the Electronic Visualization Lab at University of Illinois, Chicago, and is currently maintained there by Alex Hill.

Virtual reality is a technology that, until recently, has not been generally accessible, particularly for artists. While VR has been used for decades in science, engineering, medicine, and military simulators, both the cost and technical complexity of the systems have limited the availability of the technology in the arts, education, or even in entertainment. In recent years, rapid increases in computing power and falling prices have brought the cost of an immersive display system down significantly, opening new opportunities for museums, art galleries, schools, and other areas in the arts and humanities. However, affordable technology still needs to be usable - and this is where Ygdrasil comes in.

The main Ygdrasil home page is at http://www.evl.uic.edu/yg, where you will find the complete language reference, additional guides and tutorials, a user forum, and download and installation instructions for the most recent versions of the language. This guide is designed as a complement to the core documentation.

Ben’s course syllabus on Experimntal GameLab is an interesting “read”, too.

So Bioware is merely confirming what we “knew” all along… Good job! Bioware!
