IoT enabled smart environments typically include large number of simple sensors that are designed to detect specific events. In many environments, however, not one but combinations of sensor events represent activities of interest (such as activities of daily living of a patient in a smarthome). Detecting and monitoring these activities of interest result in both application-specific benefits and operational benefits. However, human activities often overlap, thereby making activity detection from the collected sensor events a challenging problem. In this paper, we first present the various benefits of such materialization of sensor events into activities, and then discuss the challenges in detecting diverse activities taken up by humans. More interestingly, the diversity of human activities and the time-variability of a given activity by the same human, makes reliable detection of activities even harder, and open up interesting avenues for future research.
