Today's motion sensing systems are increasingly sophisticated, to match growing consumer demand for advanced features. Two of the major trends in motion sensing technology are a greater number of sensor capabilities on a single node, which requires a low-cost local fusion process; and more nodes being used on a given object, which requires a system-wide fusion process. Under the DeMoSen project, Movea and its project partners will come up with two product roadmaps: one for a form sensing system and one for a motion sensing system for an entire object. They will also develop the main technology brick for these products: an attitude control system comprised of accelerometers, gyroscopes, and magnetic sensors with embedded electronics and low-power radio wave transmission.
The full-object motion sensing system will have between 5 and 20 nodes and will model the movement of a human body by reconstructing the chain outlined by the nodes. Target applications include video games, athletic training, and healthcare. The form sensing system will estimate the shape of an object based on signals from a large number of sensors. The system will initially target physical therapy applications, but could eventually be used in "wired" clothing that models a person's shape and posture. The main innovations to be developed under this project are: highly dense senor networks; the prioritized processing of signals from sensors at a node and system-wide level; and the use of wireless technology to send signals, allowing for greater flexibility and performance (in terms of speed and stand-alone operation) as well as compliance with the latest standards.
