Pedestrian Dead Reckoning Enables Indoor Navigation Without WiFi– Dec 16, 2013. Just as in-vehicle navigation systems have already revolutionized finding street addresses, pedestrian navigation systems aim to revolutionize finding in-door locations. To actualize a whole range of pedestrian navigation applications, Sensor Platforms in San Jose, Calif. — the software specialists licensing motion algorithms — has added Pedestrian Dead Reckoning (PDR) to its FreeMotion Library of algorithms. Sensor Platforms’ PDR system uses 10-axis sensor fusion on the data from micro-electro-mechanical system (MEMS) sensors — accelerometers, gyroscopes, magnetometers and barometric pressure sensors (for altitude) — to calculate the distance traveled by a user as well as the user’s direction (bearing), working from the last known waypoint as read off a global position systems (GPS) chip. By calibrating to the user’s context, Sensor Platforms claims its PDR solution provides accuracy within a few percent of the distance traveled from the last known waypoint. Read more.
Enabling low-power sensor context on mobile devices – July 22, 2013 Making mobile platforms context-aware is a hot topic in today’s information-rich world. Using the sensors available on these platforms, one can infer the context of the device, its user, and its environment. This can enable new useful applications that make smart devices smarter. It is common to utilize machine learning to determine the underlying meaning in the large amount of sensor data being generated all around us. However, traditional machine learning methods (such as neural networks, polynomial regression, and support vector machines) do not directly lend themselves to application in a power-conscious mobile environment. The necessary techniques for ensuring effective implementation of sensor context are discussed. Read more.
