The Fifth International Workshop on Ubiquitous Personal Assistance (UPA’20) aims to continue discussing the latest research developments and outcomes on digital personal assistants, building on the success of our four previous workshops, organized in conjunction with UbiComp’16-19. 

​The goal of the workshop is to provide a structured space to discuss the challenges, latest research developments and outcomes of digital personal assistants in relation to the different areas of human-centric assistance. This time in particular, we aim to put forward the discussion on how digital assistants can better exploit Virtual Reality (VR) and Augmented Reality (AR) technologies to provide guidance and support for specific endeavors of people's lives, such as those related to training/education, professional, and personal activities. Furthermore, this workshop seeks to find novel ways to exploit cognitive aspects, such as users' intentions, motivations, and emotions to build smarter digital assistants that better fit each particular user.
