Edge environments, such as those in which first responders and military personnel operate in, are characterized by dynamic context, limited computing resources, intermittent network connectivity, and high levels of stress. First responders and soldiers can use handheld devices in these environments to help with tasks such as speech and image recognition, natural language processing, decision-making and mission planning. Unfortunately, commercial mobile solutions often do not work because they not address the “challenges of being at the edge.” This talk will discuss potential solutions as well as open areas of research for designing and implementing mobile systems in edge environments.
