For mobile devices, sensor integration in both HW and SW is critical to meet the embedded requirements. IMHO, the application processor venders, instead of diversified sensor venders, need to offer the HW-agnostic fusion solution eventually.

The area of sensor fusion and the ability to filter and auto tune MEMs is just starting to take off. I can see opportunity in both the proprietary hardware/software as well as the more open source hardware/software approaches. The key is: performance/cost/feature tradeoffs. I would expect better performance/features in a proprietary system but at a cost. Likewise, the open ended system composed of varied vendor MEMs and a mix of software / hardware processing could yield reasonable cost/performance numbers. The overall trend towards more integration of algorithm processing with MEMs is a very encouraging one. I look forward to the continued growth and evolution that the marketplace will foster. I must confess that an integrated MEMs platform with auto-tuning/scaling and power savings is a very attractive offering.

Junko, there are many levels at which the sensor data can be 'fused' using software/algorithm-centric approaches as well as a combination of hardware and software/algorithms. Each have their advantages and access to being open and/or hardware neutral. The end application will decide what is better and the respective business model applies. Take locating some one inside a building for example -there are many methods to triangulate and fine tune a moving person within a shopping mall (many companies in this space but none have it fine tuned to less than 10m accuracy yet). This involves fusing & processing data in real time from GPS, 3G/4G/LTE radio signals, WiFi, inertial sensors and BlueTooth, all of which is done with triangulation algorithms at the software-level, mostly hardware independent/agnostic. In contrast, data from accelerometers and gyroscopes in the same package is best done at the hardware/software-level. Freescale's example cited in the article is one which allows non-Freescale micro's to access and process sensor data. But others like TI, ST, etc. may have proprietary algorithms that do compensations for noise in measured/sensed data and processing for linearity, etc., may choose to remain proprietary. MP Divakar

Sensors are Analog Elements used for sensing the real life signals, the entire instrumentation filed is focusing over the segment, but the sensors used in mobile devices are not yet fully the part of the instrumentation, but it has got equal amount of opportunities and possibilities instrumentation sensors and devices enjoys.

I’m writing on behalf of Hillcrest Labs, an expert in the kind of hardware-agnostic sensor fusion described in this article. As EE Times has covered, Hillcrest is known for selling its Freespace software and licensing its technology to companies such as LG Electronics, Roku,Sony,and others. Today Hillcrest unveiled its new Freespace® MotionEngine™ for mobile and here’s an excerpt from the release: Hillcrest's core Freespace MotionEngine software, on which the new smartphone platform is based, was recently selected as a prestigious 2012 International CES Innovations Design and Engineering Awards Honoree. Benefits of Freespace include: 1) Sensor Agnostic Solutions: Hillcrest's MotionEngine software works with sensors from all major suppliers and Hillcrest can help companies qualify sensors based on specific performance and pricing needs. Hillcrest's sensor agnostic solutions enable lower costs by providing multiple supply choices to manufacturers and suppliers, while maintaining high performance standards. 2) Superior Sensor Performance: Hillcrest's proprietary static and dynamic calibration processes deliver the industry's highest motion processing performance, backed by proven mass-market deployments of major CE companies. 3) Minimal Power Consumption: With Hillcrest's software, sensors can be context-aware to know when they are needed or not, shutting on and off to preserve battery life. 4) Essential Patent Portfolio: Hillcrest's global intellectual property portfolio includes more than 60 issued patents, with more than 200 applications pending, and provides reassurance to customers bringing new motion-based products to market. 5) Flexible Implementation Options: With a modular software architecture and flexible implementation options for processor locations, sensor configurations, and operating system support, Hillcrest can support a wide range of applications and devices.

I suspect there are more vendors offering hardware-independent sensor fusion algorithms...but then, here's a question. What is their business model going to be? Is IP licensing enough to keep the business going?

Nice piece. That is where the industry is going. That offers more value and also gives innovation a new name.
