Sensor Platforms Adds Pedestrian Dead Reckoning to Its FreeMotion Library
SAN JOSE, Calif. --(Business Wire)--
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
To create the breadth of the FreeMotion library, the company has
assembled a multi-disciplinary engineering team with proven track
records in control systems, machine learning, mixed signal design,
motion kinematics, real-time systems, semiconductor device physics, and

Comments by Market Analysts
Marwan Boustany, Senior Analyst, IHS (News - Alert) Technology:
"As the framework for indoor navigation develops in terms of maps,
wireless infrastructure and low power sensor processing, reliable and
sensor agnostic algorithms for pedestrian dead reckoning become critical
to support the range of handsets and tablets on the market. The addition
of Sensor Platform's solution to this challenge is a step towards
further enabling reliable and seamless indoor and outdoor pedestrian
Wenbin Ding, Market and Technology Analyst, Yole D�veloppement
"The market of inertial and combo sensors for consumer applications will
grow from $1.76B in 2012 to $2.99B in 2018. Market for indoor navigation
and other location-based services has thus great potential in the next
few years. Software development improves the sensor fusion and allows
sensor companies and end users to add more value and to bring these LBS
functionalities to mobile devices. Sensor Platform's FreeMotion Library
with new PDR algorithm would definitely accelerate this adoption and we
are expecting to see the market arising."
Will Strauss (News - Alert), Principal, Forward Concepts
"Although many talk about pedestrian dead reckoning, this is one of the
first comprehensive solutions that I have seen come to market. Sensor
Platforms' holistic approach to PDR is fusion-enabled and
context-enhanced with an appropriate emphasis on bearing."
Mike Feibus, Principal Analyst, TechKnowledge Strategies
"Consumers aren't going to follow orders and hold their smartphones the
way you want them to, so it's going to be very difficult to pinpoint
their location indoors if you can't account for what they're doing with
it. You have to be able to recognize if they're holding their smartphone
up to their ear, stashing it in their hip pocket or clutching it in
their swinging hand as they walk. That's why bearing is such a critical
piece of the puzzle."
