Movement Sensors a Less Invasive Alternative To CCTV

holy_calamity writes "Researchers at Mitsubishi say cramming buildings with movement sensors, not cameras, is a safer and less invasive alternative to CCTV. They covered their office building with 215 low-cost sensors to watch over their colleagues and show how it works. A video shows how a user can see people's movements on a map of the building in real time. Data from the sensors is much easier to handle than video footage, and it can easily be searched." The Surface-like UI is pretty neat too.

... or judo chopping their boss ...

Judo practitioners never chop, they trip, or throw, or choke, or break, or wrestle, or disarm, or hold down. I can't imagine any judoka being in the mood to harm own boss. OTOH I can imagine their boss wrongly suspecting them to be weed addicts.

I mean, practicing that sport sweats anxiety and adrenaline out from people rather quickly, elevating tolerance to stress and making them seem quite tension-free and sheepish to the unknowing ... until there is a threat of violence.

There are other martial art that also practice fights in trainings, but those martial arts usually don't require that much work (energy expenditure) as judo does and are more dangerous, so you have to hold back. In judo, you can let it all out, physically and emotionally. After the training, you are exhausted AND you as well have "beaten" someone, who, that's the best part, wasn't harmed in the process and there's no hard feelings. Of course, provided all the practitioners learned their techniques of safe landing well...
