Estimates of compound annual growth rate (CAGR) for wearables vary between 50% and 80% over the next 5 years. These growth rates represent an attractive market, but several barriers limit wearable device adoption. This presentation explores a broad range of these limitations (e.g., interoperability, data ownership, and security) that have applicability across many environments (e.g., industrial, military, infotainment, health & fitness). As more devices become connected to the Internet, a tremendous opportunity exists to fuse data from wearables and other "Internet of Things" devices to create innovative and compelling solutions. Often, this requires additional, adjacent architectural components such as gateways and cloud analytics, which will be briefly discussed as well. Finally, since the healthcare and fitness categories are presently the largest market spaces for wearables, the presentation covers unique challenges and proposes solutions tailored to these specific markets.

Wearables: the path to credible product category from interesting niche
James Bruce
Director of Mobile Computing

The topic of wearables has increasingly made its way into the technology headlines. This class of product represents a diverse range of devices, including bands, smartwatches and glasses. These devices typically connect wirelessly to a smartphone providing a connection to the internet. ABI Research estimated about 50M wearables shipped in 2013. At CES, Embedded World and Mobile World Congress earlier this year, a wide range of new devices were launched and with Google's announcement of an Android version, Android Wear, specifically targeted for this area, the volumes are set to more than double in 2014. As with any emerging market, the initial set of pioneering products pursue a diverse range of technology approaches, as companies explore the right balance of functionality, cost, form factor and battery life. This presentation will examine the growth and chart the future of this market, including: (a) highlighting the changes ARM expects to see in the value chain around this market, given the use cases we expect to see for this category of products, (b) predicting some of the new user interface, sensor and security functionality, not present in the first wave of devices, that will be needed to make this a viable product category and not be relegated to (relatively) small niches, and (c) explore how these current products are constructed and share some of ARM's thoughts as to how these systems and the technologies that will be needed to deliver the power and performance cost points needed for future solutions

Powering wearable device sensors for extended battery life
John Demiray
Sr. Strategic Marketing Manager, Mobile Products

Wearable devices of the future are expected to provide critical life-enhancing features. These features will support monitoring of the heart rate, blood pressure and other biometric vital signs in addition to tracking our fitness and activity levels. At the same time, they will need to connect to a network to send and receive frequent updates. Wearable devices available today do not reach their potential as a critical part of our life and health due to frequent and time consuming charging requirements. If, in the future, wearable devices are expected to be more of an extension of our health and lifestyle, technological advances are needed to reduce the power consumption of sensors and internet connectivity when these functions are not in operation. This presentation will cover the optimization of power architectures to increase the battery life and reduce the charge time of wearable devices to make them truly available in our everyday life.

Toward an open data ecosystem for wearable devices
Rachel Kalmar, PhD
Data Scientist
Misfit Wearables

From activity trackers to Google Glass, wearables are all the rage. But who should get access to the data? Unfortunately, just because you wear a device doesn't mean that you get access to your data. As a data scientist, I've been wearing 20+ activity trackers for the past 18 months. What have I learned? I've learned that I can't get my time-resolved data from these devices. Why not? Issues of privacy, lack of standards, and unclear business models for personal data collection and sharing make this difficult. Given this, where we're headed is not toward an Internet of Things, but toward many siloed Internets of Things. This talk will discuss barriers and enablers to creating an open data ecosystem that lays the foundation for one integrated network of connected devices.

Biography: Dr. Rachel Kalmar is a data scientist at Misfit Wearables, where she wrangles noisy data and tries to quantify anything and everything she can.

Rachel is an alum of the d.school, Singularity University, and Rock Health, and her favorite hashtag is #geekparadise.

Government regulations: the impact on wearable device manufacturers
Jitendra "Jitty" Malik, PhD
Alston & Bird

Wearable sensors are becoming increasingly prevalent in our society to monitor various aspects of human activity, including human physiology. Accordingly, the U.S. Food and Drug Administration ("FDA") is becoming increasingly vigilant in monitoring certain wearable technologies. Congress also is signaling its intent to scrutinize the information wearable devices collect and process. Recently, the FDA issued guidance explaining which wearable devices it intends to regulate and how it intends to regulate them. Depending on the intended application, a wearable device manufacturer could subject themselves to scrutiny from the FDA. The FDA's regulations will have broad implications for developers of wearable technologies. Among the topics covered in the talk, we will discuss the FDA regulations, including which wearable devices will be regulated by the FDA, how the FDA will make a determination whether a wearable device will be subject to its regulations, and an overview of the kinds of information a manufacturer will have to provide to comply with the regulatory regime. Some device manufacturers have already approached the FDA, and their discussions with the FDA have been made public. The contents of these discussions will be presented to provide the audience with a better understanding of the FDA's thoughts as it comes to its own regulations. We will also discuss some of the concerns expressed by Congress, and the information Congress has requested in the wearable device space, in an effort to better understand future regulatory changes.

Timing chips for wearable applications: design and performance considerations
Steve Pratt
Marketing Director

Today's wearable devices are pushing the envelope on functionality, battery life and form factor. As wearables continue to increase functionality, timing solutions help optimize the performance of all operations such as wireless connectivity, sensor interface, and MCU processing. All these subsystems benefit from small and accurate reference clocks. For example, WiFi and Bluetooth Low Energy (BLE) wireless connectivity must be maintained between the wearable device and a mobile phone. During long periods of inactivity, an accurate sleep clock will significantly improve battery life in wearables by enabling longer sleep intervals and fewer and shorter transmissions. Similarly, non-real time data transfer of real-time sensor activity occurring between periods of data transmission requires accurate time stamping. And the wearable's MCU reference clock must be precisely picked for the optimal operating frequency and duty cycled to optimize power. While the traditional quartz oscillators meet the power and accuracy specifications of wearable devices, they cannot easily meet the size requirements. On the other hand, unlike quartz, MEMS based oscillators are advantageous for wearable device applications because they can meet the all three main requirements -- power, accuracy, and size -- in combination. The MEMS oscillators' advantage stems from the fact that they can put into a chip-scale package (CSP), while quartz is limited to ceramic packages that are bulky. This talk will provide an overview of where timing chips are used in a typical wearable device system, how they affect the overall performance, and what can be done to make wearable devices more efficient.

Strategies for security in the wearable ecosystem
Ray Potter

Wearables play a critical role collecting, processing, and archiving increasingly personal data. Security strategies must be robust to match the importance of the information at stake, even if the device itself is scaled down. Our biggest problem? It simply isn't easy to design strong security with such constrained space requirements. Practitioners have a running start, building on successes with smartphones and tablets, but the challenge is taken one step further with today's tiny but surprisingly powerful wearable devices. This talk will cover: (1) potential vulnerabilities in wearable devices, (2) technical constraints in the leading wearables that make security challenging, (3) similarities to other mobile devices and lessons learned, (4) techniques used in mobile security that will apply to wearables, and (5) industries and verticals which will have use cases for secured wearable devices.

Integrating sensors seamlessly with clothing in mass production
Akseli Reho

To integrate sensors seamlessly with clothing is meaningful because then wearable devices are built into what we are already used to wearing all the time. Thus, clothing and textile accessories are a natural platform for gathering biometric sensor data from the human body. Also, the trend of sensors and other electronics shrinking in size, appearance and cost is supporting the integration trend with textiles. But, on the other hand, clothing and especially underwear is a challenging integration platform. The material volume of the product is minimal, the maintenance environment like machine washing is harsh, the design plays a big role, and the price and logistic targets are tough, etc. New technologies and interdisciplinary approaches are needed to make sensor integration with textiles come true. In this presentation, I will discuss the characteristics of embedding and integrating sensors into textiles in mass production scale, both for sports and medical applications.

Biography: Akseli Reho is the founder and CEO of the Finnish wearable sensor company Clothing+. With a M.Sc. degree in telecommunications, Mr. Reho has been an active member in the wearables community since 1998 and his work has been instrumental in bridging the gap between electronics and textiles in manufacturing. Under his direction, Clothing+ has been mass-producing millions of textile-integrated wearable sensors since 2002 and continues to make an ever greater impact on the sports and medical markets.

MEMS and sensors in wearables: market overview
Jordan Selburn
Sr. Principal Analyst

Wearable electronics have rapidly emerged as the next big wave for MEMS and sensors in consumer electronics after smartphones and tablets. We predict that close to 500 million sensors will ship in wearables by 2019 up from 66 million units in 2013. The presentation will analyze the market by wearable device and by sensor type. The market drivers for this sensor boom will be reviewed, including: (1) fitness and health monitoring, and (2) sensors for user interface applications, especially MEMS microphones for voice command. Notably, the adoption of environment monitoring sensors (such as humidity, UV, and others) results more from a technology push, by both sensor suppliers and wearable device OEMs, than from a real pull from the consumers. This talk will also assess the impact of the ecosystem on the adoption of sensors (for example, the influence of dedicated operating systems such as Google Wear and sensor hubs). Finally, the specificities of the wearable market will be reviewed, as compared to handsets, along with the opportunities and risks it bears for sensor suppliers.
