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 Sensor Platforms.

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 as well.

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 (

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 battery life.

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 signal processing.

The company is located at 2860 Zanker Road, #210, San Jose, CA (News - Alert) 95134. For information:

Sensor Platforms Adds Pedestrian Dead Reckoning to Its FreeMotion Library

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 navigation."

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."
