Cheap Motion Capture Device to hit market soon
Wow. Sensors are SOOOOO ubercool. Now the motion capture monopoly that is Vicon and its associated studios might fall - very soon. Researchers from the MIT(USA) and MERL (Zürich, Switzerland) have created a system using of the shelf motion sensors such as the one that is found in the Wii controller and ultrasonic sound to create a $3000 motion capturing system that already rivals the vicon - and its only an alpha alpha version. They say the price could easily fall to a "couple hundret bucks". For comparison - a Vicon system that is actually usable cost upward of $250.000 - and that is in no way even close to perfect as every visual motion tracking has to deal with "blind spots" - tracking points that are invisible for a couple of frames because they are obscured by body parts or other bodies. The problems come if these points are then popping up in a different place after they had been obscured leading to absolutely unusable tracking data that has to be cleaned in a very tedious manual labour process.
The Vicon system has 5+ highresolution highspeed infrared cameras (we are talking about 2000lines resoltion and 200 frames per seconds here - you know where the price comes from) so this system will not fall in price anytime soon.
So as a 3d artist I can not stress how great it would be just to slap a <$500 motion capture system on any actor, have them do their dance and then have ready to use data. Especially since this can be employed outside a studio - so to say on set!
But also this would make the Wii look like a stone age gaming device. Imagine playing a boxing game with one of these.....
