1 BACKGROUNDAttention is one of the most precious resources we have,yet, today’s ubiquitous computing environments indiscrimi-nately exploit this resource for individual applications’ ben-efits. Devices and services are proactively seeking our atten-tion through notifications: visual, auditory, or tactile alerts in-tended to draw attention to events that took place outside of auser’s focus [8]. Attention grabbing is rapidly becoming inte-gral to many ubiquitous computing platforms, such as smart-phones, desktop computers, and vehicles, where notificationsare used by multiple applications and services [18, 22], suchas social networks, email clients, or driving alert systems.

Despite the benefit of triggering a timely reaction, andindeed, potentially legitimate steering of a user’s attentionto critical information, research has repeatedly shown thatnotifications can be distracting, causing a negative effect ontask performance [3, 5, 7, 8, 12, 19], increasing stress [11],and reducing wellbeing [10]. Furthermore, often used bycommunication platforms [4, 6, 16, 18], notifications carrycertain social expectations towards responsiveness, result-ing in added pressure to attend notifications. Consequently,disabling notifications, despite their known disadvantages,for many people is not an option [6, 8, 12].At the core of the issue with distraction in ubiquitous

computing environments lies our limited cognitive capac-ity. Different cognitive loads demanded by the offline andonline tasks we perform, tasks signaled by notifications, aswell as tasks performed while the notifications are buzzing,make it challenging for the user to triage their attention effi-ciently. Eventually, this leads to the problems of informationoverload and overchoice—in our opinion two of the most rel-evant problems in information technology for the next fewdecades. In the era of the Internet of Things (IoT) we haveto handle incoming notifications from both our personal aswell as ‘other’ devices. Together with developments in smartcity environments or with smart mobility, this informationoverload is expected to grow.Recently, we have seen an increase in novel attempts to

address these problems by utilising contextual data [7, 9, 13,15, 17, 20] or notification content [14, 21] in order to delivernotifications at more opportune moments, the use of ambientinformation presentation or augmentation, or by making iteasier to deal with interruptions [2]. However, significant

challenges, especially along the lines of understanding cog-nitive load and our information processing limitations [1], aswell as devising technologies that interact with their usersin adaptive multimodal ways, still remain.

2 UBITTENTION 2020 WORKSHOPIn this workshop, we will bring together people from indus-try and academia who are active in the areas of attentionresearch, context-aware and ubiquitous computing, person-alization and adaptation, and ambient and multi-modal in-teraction. The main objective of UbiTtention 2020 is to sharethe latest research on user attention and notification manage-ment in several research areas and contexts, including HCI,systems research, user studies, IoT, smart cities, smart homes,and smart vehicles (as shown in Table 1). Further, this work-shop aims to identify future research challenges, researchopportunities, and applications of our research outcomes tosociety at large.This workshop is a follow-on from the successful Smart-

tention, Please! workshops at MobileHCI 2015 and 2016, andthe UbiTtentionworkshops at UbiComp 2016, 2017, 2018, and20191. Last year, the UbiTtention workshop received 12 inno-vative papers and more than 35 participants on the venue ofUbiComp 2018. While the Smarttention workshops focusedmore on mobile notifications, the subsequent UbiTtentionworkshops focus on a larger understanding of the differentroles notifications can play in a wide variety of computing

environments including the office, the home, in cars, as wellas other smart environments.

Relevance and impact to UbiComp: UbiTtention’s fo-cus on user attention and notifications is related to key re-search fields of UbiComp, such as HCI, mobile computing,IoT-based services, and others, thus the workshop has sig-nificant potential to impact and contribute to all the listedareas.

In addition, past UbiComp papers represent a cornerstoneof attention management research [1, 13, 15, 22], making Ubi-Comp 2020 the ideal venue for UbiTtention 2020 workshop.The impact is bidirectional, as the tradition of UbiTtentionbeing collocated with UbiComp has resulted in a number ofcontributions initially presented and shaped by discussionsat UbiTtention, ending up published in ACM IMWUT.

Finally, UbiComp is rapidly engaging machine learning re-searchers and practitioners interested in making real-world

impact. In line with this trend, UbiTtention 2020 introducesthe cognitive load inference challenge (see Section 5), thusproviding a collaboration platform for machine learning,ubiquitous computing, and psychology researchers. Our pre-liminary contacts with diverse research groups from academiaand industry, e.g. Dr. Garbas (Fraunhofer IIS), Dr. Lustrek (In-stitute Jozef Stefan – winners of last year’s UbiComp HASCAand Emteq challenges), and Dr David (Kassel University),who have expressed interest in participating in such a chal-lenge, point out that UbiTtention may promote UbiCompparticipation within a rather diverse audience.

Long-termobjectives:Theworkshopwill lead to a deeperunderstanding of cognitive load, notifications, and attentionmanagement. We plan to consolidate and significantly ex-pand an already vibrant research community formed aroundthe previous installments of UbiTtention. More specifically,we are already communicating with Springer publishing houseabout a book on the topic of attention management in ubiq-uitous computing, and UbiTtention will help us to identifycutting edge research contributions whose authors will beinvited to contribute chapters to the mentioned book.

3 WORKSHOP STRUCTUREWe plan UbiTtention 2020 as a full-day workshop, aiming tobring together practitioners and academics. The key partsof the workshop include: a keynote, a paper presentationsession, and an open-data challenge.

Previous years have demonstrated the benefits of keynotetalks that enable UbiTtention audience to gain deeper in-sights on a particular research achievement in the area ofattention management. Moreover, we found that the work-shop keynote format enables a larger degree of interactionbetween the presenter and the audience. We will strive tohave a female and/or a minority keynote. Potential candi-dates we plan to invite include Shamsi Iqbal, Gloria Mark,and Mary Czerwinski.The second part of the workshop consists of short pa-

per presentations. UbiTtention does not aim to be a mini-conference, thus, the paper presentations are not a goal perse, but a means to spark discussion with the audience. Thediscussions serve as an early feedback and brainstormingsession aimed to help presenters steer their future researchendeavors. UbiTtention papers will not be selected merely ontheir technical quality, but the likeliness of the topic sparkingdiscussion at the workshop. Papers describing an early-stagedemo products will be especially welcome.

Finally, a novel part of this year’s UbiTtention is the open-data challenge. The challenge, motivated by a discussionheld at UbiTtention 2019, where the lack of open datasetsused for the evaluation of different approaches towards at-tention management was highlighted, enables researchersto develop and evaluate innovative solutions in the area of

cognitive load inference, one of the key sub-areas supportingattention management in ubiquitous computing.

4 WORKSHOP PAPERSOur workshop will ask for papers outlining new insights inthe topics listed in Table 1. The papers are written in theSIGCHI Extended Abstract format with a length of 4 to 6pages and are to be included in the ACM Digital Library.Call for papers will be sent to all relevant mailing lists ofseveral research communities, including those of UbiCompresearch, HCI, mobile interaction, as well as the IoT, smartcity, smart home, and smart vehicle communities. Further, thecall will be distributed to participants of the previous Smart-tention and UbiTtention workshops. Finally, information willalso be shared on the workshop website and Facebook page.We aim for a selection of 10-15 workshop papers. Submis-sions will be peer-reviewed by at least two reviewers froman international PC of renowned researchers and experts.The acceptance criteria will be a mixture of relevance, nov-elty, writing, research quality, and provocativeness. With theaforementioned measures, we are confident to attract a largenumber of submissions, which will allow us to assemble ahigh-quality workshop.

5 OPEN-DATA CHALLENGETo prevent undesirable effects of attention grabbing at timeswhen a user is occupied with a difficult task, ubiquitous com-puting devices should be aware of the user’s cognitive load.When humans experience a psycho-physiological load, e.g.,in the form of a demanding task, the activation of the sym-pathetic nervous system increases. The increased activationsubstantially speeds up certain processes within the body(‘fight-or-flight’ response). It raises the heart rate, sweatingrate, breathing rate, and blood pressure; the pupils dilate;the saliva flow decreases; the heart-beats become equidis-tant; the blood flow is restricted from the extremities, andis redirected towards the vital organs. Traditionally, these

signals have been measured in highly controlled environ-ments using specialized equipment. Recently, the desire forin-situ knowledge of cognitive load has led to advances inphysiological signal-based cognitive load inference usingcommodity devices. However, inferring cognitive load is ex-tremely challenging, especially when performed withoutobtrusive, expensive, and purpose-built equipment.

To advance the field of cognitive load inference in ubiqui-tous computing, we will organize a public machine learning(ML) challenge in which competitors can build their own MLpipelines for cognitive load inference. All ML pipelines willbe trained and evaluated on the same dataset, thus enablinga systematic and comparable advancement. The dataset isthe first labelled dataset for cognitive load monitoring witha wristband and it will be fully released after the challenge.During the challenge, the participants will only have accessto a labelled training subset and unlabelled test subset. Thelabels of the test subset will be kept in secret. The dataset wascollected in a quiet, normal-temperature roomwhile workingon a PC with the wristband strapped to her non-dominantarm. Twenty participants attended these experiments. Thetechnical details of the challenge are described in the call forparticipation.

6 CONCLUSIONThe successful UbiTtention series of workshops on user at-tention and notification management has provided valuablelessons both for academia and industry in the fields such asHCI, mobile computing, and IoT-based services. The dynamicdevelopment of these fields seeks for continuous and activeaddressing of the related research challenges and opportuni-ties. We expect that approximately 35 participants, leadingUbiComp machine learning teams, and organizers who haveled the community for the past five years, will ensure thatthis year’s UbiTtention showcases the latest research on userattention and notification management, thus empoweringfurther growth and enabling transition of this knowledgeinto applications that can positively impact the society.
