The articles in this special section focus on out-of-the-laboratory pervasive computing. The radical societal changes we are witnessing as a result of COVID-19 are giving rise to not only new challenges but also new opportunities for pervasive computing and its researchers. As social distancing measures are making it harder to conduct lab-based user studies and in-person observations, researchers are now faced with the challenge of designing and conducting studies remotely. Many examples of out-of-the-lab research exist from the time before COVID-19, in particular, leveraging pervasive technologies, such as mobile phones2 and smartphones,3 public displays4 , smart watches,7 smart glasses,1 and VR glasses,5 to just name a few examples.

Describes a wearable computing system with a head-mounted camera that can be used as a personal guide in an art gallery or museum. Features of the system; System overview; Applications of the system.

Presents information on a study which described a real-time computer vision and machine learning system for modeling and recognizing human behaviors in a visual surveillance task. Overview of the system; Description of the computer vision techniques used for segmentation and tracking of the pedestrians; Information on a synthetic agent environment created in the study.

The objective of this special issue is to revisit how sensor technology is transforming the way context and human behavior is understood, enabling personal and enriched media experiences. [ABSTRACT FROM AUTHOR]
