Workshop Theme and Goals

In the advancing ubiquitous computing, users are increasingly confronted with a tremendous amount of information proactively provided via notifications from versatile applications and services, through multiple devices and screens in their environment. Thus, human’s attention has been getting a new significant bottleneck. Further, the latest computing trends with emerging new devices including versatile IoT devices, and contexts, such as smart cities, smart mobility including vehicles, are even accelerating this situation. In such situations, “attention management”, including attention representation, sensing, prediction, analysis and adaptive behavior in the computer systems, are needed in our computing systems.

Following the successful UbiTtention 2016, 2017, 2018 and 2019 workshops, the UbiTtention 2020 workshop brings together researchers and practitioners from academia and industry to explore the management of human attention and smart and ambient notifications with versatile devices and situations to overcome information overload and overchoice.

In this workshop, we want to focus on a larger understanding of the different roles notifications can play in a wide variety of computing environments including the office, the home, in cars, and other smart environments. In addition, we introduce an open-data machine learning challenge to advance the field of cognitive load inference in ubiquitous computing. The dataset is the first labelled dataset for cognitive load monitoring with a wristband and it will be fully released after the challenge.

Topics of the workshop include, but are not limited to:

  • Understanding behavior and habits around notifications
  • Detection/prediction of availability, attention, and opportune moments for interruptions
  • Ambient, peripheral, distributed and multimodal presentation of information or augmentation
  • Timing of pro-active recommendations and user engagements
  • Infrastructures, frameworks and tools for the development of smart attention systems
  • Strategies for attention management from notifications of IoT devices
  • Understanding users' behavior and habits around notifications and interruptions, including longer term user engagement and behavior change
  • Use of ambient representations for big data analysis
  • Management of information overload in smart city environments and cyber physical systems or smart mobility and vehicle environments
  • Notifications in virtual reality (VR) and augmented reality (AR)
  • Supporting the digital wellbeing of users


On ecological validity, interruptibility and sample sizes

SWe will discuss our experiences with utilizing experience sampling and similar methods towards the end of ecologically valid studies on topics varying from human interruptibility and security. We will also discuss lessons we have learned about sample sizes used in HCI studies utilizing machine learning.

Submission Details

A paper should have a length of maximum 6 pages (including references) in the ACM SIGCHI Master Article template with 2 columns (see also: ) and will be reviewed by at least two workshop organisers. Successful submissions will have the potential to raise discussion, provide insights for other attendees, and illustrate open challenges and potential solutions. All accepted publications will be published on the workshop website and in the ACM Digital Library.

At least one author of each accepted paper needs to register for the conference and the workshop itself. During the workshop, each paper will be given time for an oral presentation. In addition, there will be room for demonstrations and hands-on sessions.

Machine learning challenge for monitoring cognitive load

A machine learning challenge for detecting cognitive load, with results to be presented at the Ubittention workshop at UbiComp 2020, Cancun, 12 - 13th September 2020. The goal of this machine learning challenge is to recognize 2 levels of cognitive load from the sensor data of a wearable wrist-band (Microsoft Band 2). The participants will have to develop a machine-learning pipeline that will process the sensor data, create models and output the recognized cognitive load. The best three teams will also receive prizes.


  • 1. 1000 EUR
  • 2. 650 EUR
  • 3. 350 EUR
*Note: Prizes may increase subject to additional sponsors.


  • 15.3.2020 - Labelled training data is provided
  • 01.06.2020 - Participants registration deadline (see below)
  • 23.4.2020 - Unlabelled test data is provided
  • 19.6.2020 - Submission deadline: predictions + workshop poster
  • 3.7.2020 - Review notification
  • 17.7.2020 - Camera ready poster submissions
  • 12.9.2020 - Top x (max 5) teams present their work at the workshop
  • 20.9.2020 - Release of the ground-truth of the test data

Each team should send a registration email to as soon as possible but no later than 1.6.2020. The email should include the following information:
