Context-Aware Computing in the DoD

Jeff BolengIn their current state, wearable computing devices, such as glasses, watches, or sensors embedded into your clothing, are obtrusive. Jason Hong, associate professor of computer science at Carnegie Mellon University, wrote in a 2014 co-authored article in Pervasive Computing that while wearables gather input from sensors placed optimally on our bodies, they can also be “harder to accommodate due to our social context and requirements to keep them small and lightweight.” For soldiers in battle or emergency workers responding to contingencies, seamless interaction with wearable devices is critical. No matter how much hardware soldiers wear or carry, it will be of no benefit if they have to stop what they are doing to interact while responding to enemy fire or another emergency situation. This blog post describes our joint research with CMU’s Human Computer Interaction Institute (HCII) to understand the mission, role, and task of individual dismounted soldiers using context derived from sensors on their mobile devices and bodies to ensure they have the needed information and support.

HTML5 for Mobile Software Applications at the Edge

Grace Lewis Many warfighters and first responders operate at what we call “the tactical edge,”  where users are constrained by limited communication connectivity, storage availability, processing power, and battery life.  In these environments, onboard sensors are used to capture data on behalf of mobile applications to perform tasks such as face recognition, speech recognition, natural language translation, and situational awareness. These applications then rely on network interfaces to send the data to nearby servers or the cloud if local processing resources are inadequate. While software developers have traditionally used native mobile technologies to develop these applications, the approach has some drawbacks, such as limited portability. In contrast, HTML5 has been touted for its portability across mobile device platforms, as well an ability to access functionality without having to download and install applications. This blog post describes research aimed at evaluating the feasibility of using HTML5 to develop applications that can meet tactical edge requirements.

Establishing Trust in the Wireless Emergency Alerts Service

This blog post was co-authored by Robert Ellison.

Carol Woody The Wireless Emergency Alerts (WEA) service went online in April 2012, giving emergency management agencies such as the National Weather Service or a city’s hazardous materials team  a way to send messages to mobile phone users located in a geographic area in the event of an emergency. Since the launch of the WEA service, the newest addition to the Federal Emergency Management Agency (FEMA) Integrated Public Alert and Warning System (IPAWS),“trust” has emerged as a key issue for all involved. Alert originators at emergency management agencies must trust WEA to deliver alerts to the public in an accurate and timely manner. The public must also trust the WEA service before it will act on the alerts. Managing trust in WEA is a responsibility shared among many stakeholders who are engaged with WEA. This blog post, the first in a series, highlights recent research aimed at enhancing both the trust of alert originators in the WEA service and the public’s trust in the alerts it receives.

Situational Awareness Mashups at the Tactical Edge

Soumya Simanta Warfighters in a tactical environment face many constraints on computational resources, such as the computing power, memory, bandwidth, and battery power. They often have to make rapid decisions in hostile environments. Many warfighters can access situational awareness data feeds on their smartphones to make critical decisions. To access these feeds, however, warfighters must contend with an overwhelming amount of information from multiple, fragmented data sources that cannot be easily combined on a small smartphone screen. The same resource constraints apply to emergency responders involved in search-and-rescue missions, who often must coordinate their efforts with multiple responders. This posting describes our efforts to create the Edge Mission-Oriented Tactical App Generator (eMontage), a software prototype that allows warfighters and first responders to rapidly integrate geotagged situational awareness data from multiple remote data sources.

National Deployment of the Wireless Emergency Alerts System

William AndersonThe ubiquity of mobile devices provides new opportunities to warn people of emergencies and imminent threats using location-aware technologies. The Wireless Emergency Alerts (WEA) system, formerly known as the Commercial Mobile Alert Service (CMAS), is the newest addition to the Federal Emergency Management Agency (FEMA) Integrated Public Alert and Warning System (IPAWS), which allows authorities to broadcast emergency alerts to cell phone customers with WEA-enabled devices in an area affected by a disaster or a major emergency. This blog posting describes how the Software Engineering Institute's (SEI) work on architecture, integration, network security, and project management is assisting in implementing the WEA system, so it can handle a large number of alert originators and provide an effective nationwide wireless emergency warning system.
