The article "Charting Past, Present, and Future Research in Ubiquitous Computing" by Gregory D. Abowd and Elizabeth D. Mynatt reviews the evolution and future directions of ubiquitous computing (ubicomp). The authors highlight three key interaction themes: natural interfaces, context-aware applications, and automated capture and access. They discuss the challenges and achievements in these areas, emphasizing the need to address issues of scale, including the number and type of devices, physical space, and the number of users. A new area of research, "everyday computing," is introduced, focusing on scaling interaction over time to support continuous and unstructured activities. The article also explores the social implications and evaluation challenges of ubicomp, suggesting that user-centric perspectives are crucial for effective evaluation strategies. The authors conclude by reflecting on these issues and presenting current strategies for evaluating ubicomp systems.The article "Charting Past, Present, and Future Research in Ubiquitous Computing" by Gregory D.
