Capturing the human body motion with inertial sensors, the Open Source way.
Motion capture devices have historically been prohibitively expensive, and their use was restricted to military and scientific institutions, and some audiovisual companies. In the last years MEMS based inertial sensors have experienced significant development on their precision while decreasing size and cost. In combination with the appearance and spread of some computational inexpensive sensor fusion algorithms and fast microcomputers, motion capture at domestic level is now possible. In this talk we’ll review the essential techniques to it by focusing on a system developed by the author.
He’s an artist who found on programming and hardware development a way of expanding his expressive and technical capacities. He started out as a traditional animator and then made his way into computing through 3D animation and interactive art. He worked on several audiovisual agencies, and now as a technology teacher for young people at Codemotion Kids and freelancer. Two years ago, he decided he needed a motion capture system for a performance, and seeing there was none available at a decent cost, decided to build one himself.
