Future Applications of Sensing Technologies for Fidelitous Wearable Devices (FAST FWD)
The Intelligence Advanced Research Projects Activity is seeking information on the future capabilities of wearable devices for direct and persistent sensing of an individual and their local social and physical environment. Of specific interest are potential advancements in sensing capabilities that enable accurate, continuous measurement with devices that are relatively imperceptible to the user and seamlessly integrated with their daily activities. This request for information is issued solely for information gathering and planning purposes; this RFI does not constitute a formal solicitation for proposals. The following sections of this RFI define the overall scope of the technical domain of interest, along with instructions for the preparation and submission of responses.
Background & Scope
The growing capabilities of consumer electronics have enabled wearable devices1 that provide new opportunities for understanding and predicting human health, performance, and behavior. Exemplified by communities like the “quantified self” movement,2 this expanded consumer market has led to an increased appreciation for the potential value in using wearable devices to enable direct and persistent sensing of individuals and their social and physical environment. Accordingly, the most popular applications today are fitness and other lifestyle trackers3 with other wearable devices being used in, or being developed for, the workplace, entertainment, education, public safety, as well as the healthcare and medical sectors. Further, these trends in both market growth and diversification are projected to continue as wearable devices advance technologically and become more integrated within our lives.4
Recent trends in the development of sensing capabilities for commercial wearables have been largely evolutionary with many new devices incorporating added features and new design, but still relying on accelerometers, gyroscopes, and GPS to infer activity based on movement. Despite this relatively narrow focus, ongoing research suggests there are many more signals and features to be captured and extracted by sensors that can be easily and comfortably worn throughout the day.5 However, in all cases there are concerns about the accuracy of existing sensors and the actions and behaviors they purport to measure,6 which only serve to highlight the relatively small—but growing—body of research and researchers actively examining signal fidelity across a range of activities and conditions. By developing these pockets of promising research and development into valid, accurate sensing capabilities, the benefits of novel wearable devices are potentially far-reaching for a variety of personal, professional, and scientific uses. Rapid development of this pipeline may yield innovative, and potentially disruptive, sensing capabilities for future wearable devices.
Accordingly, IARPA is soliciting responses to this RFI to better characterize sensing capabilities of wearable devices that go beyond current prototypes in development and extend up to 10 years in the future as computing, power, materials, processing, communications and design advance and converge to enable devices capable of persistent sensing with high fidelity. This RFI seeks information regarding the future form of wearable devices and innovative ideas about significant advances in sensing capabilities that can be used to leverage the wearer of such devices—the human—as a sensor of their own biology and behavior, of those around them, and of their real world environment. IARPA is not seeking technology development concepts, but rather what sensing capabilities will be possible with future wearable devices embedded within our daily lives.
Responses to this RFI should discuss the five following aspects of future wearable sensors and their local or remote set of applications. Responses should address all five points.
1. What is the form and fit of the proposed wearable sensor(s)? Respondents should assume that computing, communication, and battery technology will advance at historical rates, enabling a device with the following characteristics:
- Persistent battery life, processing power, and transmitter functionality and speed that enables continuous sampling and near real-time feedback to the user;
- Comfortable enough to be imperceptible to the wearer throughout waking hours and during sleep;
- Ergonomic design and size that does not obstruct normal movement, circulation, respiration, ingestion, digestion, neural function, social dynamics, or other activities and processes;
- Space for single or multiple sensors; and,
- Durability and robust to some environmental conditions (e.g. temperature, moisture) and large impacts or forces.
**Respondents that believe some or all of these assumptions will not hold true should specify theoretical, empirical, and practical reasons why they will not hold and provide a response that is consistent with their alternative assumptions.
2. What signatures will the sensor(s) measure? Responses should describe the function of the proposed new or advanced sensor(s), to include what signals and specific features will be measured, how these will be captured, and other specifications, as necessary.
3. What is the purpose of measuring the proposed signatures? This should include the broad areas of application, as well as specific behaviors or states of the individual wearer, others that might be in their social and physical environment, as well as the actual environment around them. Also, what is the benefit of using a wearable sensor that is not afforded by more standard or traditional methods used to measure the proposed signatures for the general and specific applications proposed?
4. How would testing and validation be conducted? Consider the methods, environments, control conditions or “gold standard” techniques necessary to establish the accuracy of the proposed sensing capability for the specific application described in the response.
5. What are the theoretical and/or practical limitations? Responses may discuss limitations in the context of what sensors can be worn, the signatures they are designed to measure, specific applications, and/or testing and validation.
Please note that IARPA is not seeking responses that provide new or alternative power sources, novel chip design, processing and storage improvements, or advances in transmitters or communication capabilities.
Preparation Instructions to Respondents
IARPA requests that respondents submit ideas related to this topic for use by the Government in formulating a potential program. IARPA requests that submittals briefly and clearly describe the potential approach or concept, outline critical technical issues/obstacles, describe how the approach may address those issues/obstacles and comment on the expected performance and robustness of the proposed approach. If appropriate, respondents may also choose to provide a non-proprietary rough order of magnitude (ROM) regarding what such approaches might require in terms of funding and other resources for one or more years. This announcement contains all of the information required to submit a response. No additional forms, kits, or other materials are needed.
IARPA appreciates responses from all capable and qualified sources from within and outside of the US. Because IARPA is interested in an integrated approach, responses from teams with complementary areas of expertise are encouraged.
