Press Release, News
Sensor Platforms has added Pedestrian Dead Reckoning (PDR) to its
FreeMotion Library, enabling applications such as indoor navigation,
activity monitoring, and location-based services in mobile devices.
The PDR algorithms allow accurate position results using only the mobile
device sensors, without the aid of GPS, Wi-Fi, or maps. Sensor
Platforms’ PDR solution is sensor fusion-enabled to handle magnetic
anomalies in real-world environments and context awareness-enhanced.
Employing context capabilities allows for naturalistic changes in device
placement (in-hand front, at-side, in-pocket, etc.) without compromising
performance. With the FreeMotion PDR Library, typical position estimates
stay accurate to within 5 percent of distance traveled.
Sensor Platforms utilizes context in order to separate the actual travel
direction of the user (called bearing) from the device orientation.
Other unique features include false-step mitigation, stair-elevation
tracking, and in-elevator transport. As with all Sensor Platforms
products, the PDR Library is both sensor and platform agnostic.
“With the introduction of bearing, we can now offer the best-in-class
solution for PDR that will expand the demand for, and the utility of,
ever-more useful context-aware mobile devices,” said Dan Brown, CEO of
The Sensor Platforms PDR Library enables a vast array of indoor location
based service applications in addition to indoor navigation such as
point of purchase coupon delivery. Greater accuracy and incorporation of
context capability also opens significant possibilities for enhanced
user experience related to health and activity monitoring applications
Engineering Efficiency for Adopters
The FreeMotion Library is architected so that it can run on a single
processor, or be distributed among a processor, a sensor hub and/or
intelligent sensors. Sensor Platforms can help mobile system and
platform developers customize the FreeMotion Library to their specific
system implementation in order to support sensors from any major
suppliers while still delivering superior results.

About Sensor Platforms Inc (www.sensorplatforms.com)
Sensor Platforms is a venture-financed company located in Silicon Valley
that develops, for licensing, algorithmic software enabling consumer
applications to better understand user contexts and intent.
The company’s FreeMotion Library makes sensor fusion and user context
awareness available in smartphones and tablets, in order to: combine and
process data from installed sensors and microprocessors; better
interpret users’ movements and situations; and infer users’ intents.
The library makes it easy for device OEMs to purchase their sensors and
microprocessors from multiple suppliers without damaging user
experience. It also automatically optimizes sensor and platform power
consumption based on user movement and contexts, to enable longer
