There is some confusion in the article about Po-motion - Lumo is a different application, built in Unity and designed to run on a small processor. We used what we learned developing Po-motion (which is built in AIR) but it is a completely different platform. We'll be providing a styleguide and SDK for Unity developers, and we're planning to support them as they come up with new ideas for the system. The main challenge was making a turnkey unit that parents could afford. I'm excited to see what other people come up with for it. :)

Yes, that is my fault. I read the Po-motion page first and came to the wrong conclusion that your Lumo system was based on Po-motion. I realized my mistake after hitting send, of course. But, as I understand it, you have reduced the hardware of Mandala, an Amiga, a projector, and a camera down to one thing to plug into the wall that provides all of those features and probably a similar level of performance to what was available in 1988 (depending on CPU choice, ARM has come a long way since the 68030 was released). I would love it if one of the Mandala creators were around to pipe up (last I left them they were following the Grateful Dead around the world and living out of Hare Krishna temple/hostels). IIRC, they were also from Canada, though I don't remember which city.

BTW, you should probably update your Lumo page to indicate that you are using an ARM CPU, or perhaps "an Android-compatible CPU", rather than an "Android CPU". As for cost, running Android on an Intel NUC would certainly increase your cost, but could also increase your performance by enough to allow orders of magnitude more challenging applications, maybe for the Hammacher Schlemmer version :P.

The statement that the projector "plays" motion reactive games seems misleading, but for a typical consumer audience I can understand the simplification.

Meg, out of curiousity, other than not needing a stand-alone computer and video input, how does your product differ from Mandala, which was introduced by Very Vivid back in 1988, for the Amiga? It could use any video source (usually a projector aimed at a wall, but most any video output device would suffice) along with a video input from a camera to allow interacting with on screen content, and was quite popular with museums and other entities for setting up interactive displays in the early '90s, prior to Commodore's demise. Do you have anyone working on your team that has ever dealt with a Mandala, or even old enough to remember one?

At a hardware engineering level, has more been done than reducing part count, in effect? The Mandala was purely 2D, for example, having only the ability to determine motion on an X/Y basis parallel to the video display. Have you added another axis since you are supporting the 360 Kinect, perhaps, or could you consider that for your next generation? Additionally, would the use of 1080p or higher resolution video cameras make supporting resolutions higher than 1024x768 feasible in the future, or give more precise movement tracking? What is the granularity of movement tracking currently?

On a software level, how easy is it describe interactive objects and the interactions that can be performed along with the results? What would it take for Minecraft, for example, to be ported so that no controller was needed, just a lot of movement (my nephew REALLY needs some exercise!)? Or is it only really suited for new applications built from the ground up using your Po-Motion tools?

What genocide? Less Palestinian were killed by Israel (including combatants) since the conflict started 100 years ago than Syrians over the past two years.

The Palestinians in both Gaza and the west back, individually, experience a positive natural growth.

If Israel is trying to commit genocide, it is criminally ineffective.

Comment Re:True on water as well (Score 1) 60

On a ship, the captain and the pilot are two different roles and never the same person. It is the captain who has ultimate authority, the pilot is a person brought in on a case by case basis to help the captain navigate through local waters. Captains might travel the world, pilots stick to a particular stretch of water and have the local knowledge to advise the captain, usually as a requirement of maintaining insurance in case of accident. My grandfather was a ship's captain away from home almost 9 months a year, my uncle was a pilot on the Panama Canal and slept at home almost every night.

Not only does it affect the peanut allergies in Israel (less than 1%), this snack was, in fact, the tirgger that started this particular research.

The story according to the local papers is that the researcher was in a conference in Israel, and, as usual, asked who here has a child that is allergic to peanuts. Unusually, however, hardly anyone raised their hands. That triggered discovery of Bamba.

In fact, during the research, Bamba is what they fed the non-control group children.

Comment Not used in concentration camps (Score 2) 224

Excuse my nit picking, but the Nazis hardly used gas chambers in concentration camps. Mostly, they built special camps dedicated for murdering (mostly Jews, but it depends on the camp), and gas chambers was mostly used in those. These are, generally, refered to as "Extermination camps".

There were gas chambers in some of the concentration camps as well, but their use there was relatively marginal. Most people who died in concentration camps died from the cold, starvation and diseases, as well as direct murders (i.e. - getting shot).

What game theory has to say about that is to point out that these systems only work so long as the number of participants is small enough. Once the number of participants gets too large, it is impossible to effectively punish the leachers, and the entire system falls apart.

I guess we need to add to GP's original question the criteria of "works on a large scale"

Depends on when you are talking about. Pre-2K, with the aid of an FO (Forward Observer), the shells could get fairly accurate by the 6th or 7th shell, 10th if the seas are high. Given the size of shells involved, though, that means you probably leveled an area the size of a small shopping center to hit the outhouse that had been your target.

Today, totally different story. With laser guidance from an FO, tiny little winglets will dance enough that as long as your target is within a cone of the shells target it will be hit within 1 meter. No FO? GPS guided shells will hit typically within 3 meters of whatever dot you put on your map. And if you can get optical terminating shells, they don't have the ability to just hit a window, but a particular pane of a window. Look up for yourself what Jane's has to say about cruise missile accuracy for projects like JASSM (because I don't recall what I am at liberty to disclose and too lazy to look it up from a beach in Thailand). Artillery shells can be built that have every bit of accuracy, just less distance and less cost per shell (until you include the cost of the ship, the crew, the support crew, etc...). This is done for land-based artillery guns and tank shells, as well. If you watch cable TV, I am sure you can find one of those "10 Best Whatevers" that will wrap shiny graphics and add in a few reasonably knowledgeable experts around Jane's information.

When I interview, I start by asking the applicant about their general background. What projects they have worked on.

I then try to pick something from that specific knowledge domain and ask about that. I typically ask them to describe, in detail, a project they have been involved in, or ask a question about it.

My personal experience: most know nothing about the specific domain in which they have participated.

Some of the answers I've received were embarresing. People volunteering knowledge in C++ STL and BOOST, working with smart pointers, who have no idea how shared_ptr works or what its drawbacks are. People saying they used multiple inheritence and virtual inheritence (I would never bring it up on my own as I know many people consider it a niche) who don't understand how virtual inheritence actually work. People who built communication platforms for VOIP who cannot answer why/whether/when UDP is better than TCP.

So, no, programmers suck even when you ask them about their own knowledge domain. I usually end up recommending someone without experience but with the right spark in their eyes, figuring my time is better spent growing a bright newbie than fighting with bad habits by a someone with good-for-nothing "experience".
