TUTORIAL SUMMARY

Physical activities play a crucial role in the way we structure our lives. Which activity, and how it is performed, can reveal a person’s intention, habit, fitness, and state of mind; it is therefore not surprising that a range of research fields, from cognitive science to healthcare, display a growing interest in the machine recognition of human activities. In 2014, Bulling et al. designed and organized an exceptionally well-received tutorial on human activity recognition from wearable sensor data. They introduced concepts such as the Activity Recognition Chain (ARC), a framework for designing and evaluating activity recognition systems, as well as a case study demonstrating how to work with this ARC. Within the last decade, deep learning methods have shown to outperform classical Machine Learning algorithms. We argue that releasing an updated tutorial that is adapted to work with deep learning techniques is long overdue.

This tutorial introduces the Deep Learning Activity Recognition Chain (DL-ARC), which encompasses the advances that have been made over the years within the field of deep learning for human activity recognition and deep learning. Our work directly ties into the works of Bulling et al. and functions as a step-by-step framework to apply deep learning to any activity recognition use case. Within this tutorial, we will show how state-of-the-art models can be achieved, while along the way explaining all design choices in detail.

This tutorial functions as a guide in the typical processes to design and evaluate deep learning architectures, once a human activity dataset has been recorded and annotated. We show through code snippets in a step-by-step process why certain steps are needed, how they affect the system’s outcome, and which pitfalls present themselves when designing a deep learning classifier. Participants do not need prior knowledge in human activity recognition or deep learning techniques, but should be familiar with programming in Python.

Wearable Technology Design and Accessibility Considerations Tutorial
Whenever designers start out to create a piece of wearable technology there are some standard human factor considerations that we all have to think through. These might include where on the body it is the easiest to sense certain biosignals or types of movement, or they could include factors surrounding the social acceptability of interacting with on-body interfaces. It might be important to understand the human body’s ability to feel and recognize vibration and on-body location. In any case academic literature on these human factors topics is broad and dispersed through the many different disciplines associated with wearable technology. Although there have been attempts to collect this information in survey papers on the subject of designing wearable technology, new information comes out quickly and compiling all the information necessary is difficult in the format of an academic conference article. These survey articles directed at the computing science (or other specific) community might also not have impact with the design community at large.
What is also important to consider at the beginning of a wearable technology project is how the decisions made about the interface and on-body location effect accessibility. Poor decisions made in the beginning of a project can greatly effect accessibility and the ability of a large part of the population to use a wearable device. These decisions about interfaces and displays can be very hard to overcome at the end of a project and often can lead to additional costs and applique style add on accessibility solutions that do not seem cohesive with the original design.

wearables can sense human bodies

We would like to invite you to participate in the ISWC / UBICOMP (Sept 21 – 26, 2021 Virtual) Wearable Technology Design and Accessibility Tutorial. In this workshop we will explore how to develop a robust set of design and accessibility considerations (guidelines) for wearable technology. We will try out a new Wearable Technology Designer’s Web Tool (WTDWT) http://wearabletechwebtool.ipat.gatech.edu and discuss what features or information it might be missing. At the core of our workshop is an effort to understand how to train designers and developers of wearable technology to think about all users and accessibility.
There is no required submission to participate in this workshop, however we ask that you come to the workshop with a basic wearable technology idea or product you would like to create. We will form groups and work through the early stages of the design process for some of these ideas using the WTDWT.
Participants will receive a .pdf document of information tailored to their projects. Participants will be able to use the WTDWT for future projects and allow their students to use the tool as well. We hope through discussion to collect new information and considerations that might make the tool more useful.

HASCA 2020: 8th International Workshop On Human Activity Sensing Corpus And Applications

http://hasca2020.hasc.jp

ORGANIZERS

Kazuya Murao (Ritsumeikan University, Japan), Yu Enokibori (Nagoya University, Japan), Hristijan Gjoreski (Ss. Cyril and Methodius University, Macedonia), Paula Lago (Kyushu Institute of Technology, Japan), Tsuyoshi Okita (Kyushu Institute of Technology, Japan), Pekka Siirtola (University of Oulu, Finland), Kei Hiroi (Nagoya University, Japan), Philipp M. Scholl (University of Freiburg, Germany), Mathias Ciliberto (University of Sussex, UK)

WORKSHOP SUMMARY

The recognition of complex and subtle human behaviors from wearable sensors will enable next-generation human-oriented computing in scenarios of high societal value (e.g., dementia care). This will require large-scale human activity corpuses and much improved methods to recognize activities and the context in which they occur.

This workshop deals with the challenges of designing reproducible experimental setups, running large-scale dataset collection campaigns, designing activity and context recognition methods that are robust and adaptive, and evaluating systems in the real world. We wish to reflect on future methods, such as lifelong learning approaches that allow open-ended activity recognition.

The objective of this workshop is to share the experiences among current researchers around the challenges of real-world activity recognition, the role of datasets and tools, and breakthrough approaches towards open-ended contextual intelligence. This year HASCA will also welcome papers from participants to the Third Sussex-Huawei Locomotion and Transportation Recognition Competition (http://www.shl-dataset.org/activity-recognition-challenge-2020/) as part of a special session.

Beyond Steps: Challenges And Opportunities In Fitness Tracking

ORGANIZERS

Rushil Khurana (CMU, USA), Abdelkareem Bedri (CMU, USA), Patrick Carrington (CMU, USA), Daniel A.

WORKSHOP SUMMARY

The quantified-self is a positive and prevalent aspect of our culture that has progressed during the last decade propelled by technological advances in health and fitness tracking. Prior research has shown that self tracking has a myriad of benefits. And we have the ability to sense and track various aspects of fitness and well-being. However one key challenge that remains is what data needs to be shown to the user, and how to present it to the user. Moreover, when is the right time to deliver key information to the user. Secondly, we have noticed that self-monitoring and tracking research has mostly evolved in isolation i.e., researchers have separately studied or built systems for various aspects of fitness like exercise tracking, diet or sleep monitoring. While in reality many of these areas are intertwined and depend on each other: Poor sleep can lead to overeating and consequently weight gain.

In this workshop, we propose to highlight and address these two challenges and explore opportunities to expand beyond the current paradigm of single health factors tracking to a more comprehensive fitness tracking.

UbiTtention 2020: 5th International Workshop On Smart & Ambient Notification And Attention Management

WORKSHOP SUMMARY

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, attention representation, sensing, prediction, analysis and adaptive behavior in the computer systems, are needed in our computing systems.

Following the successful UbiTtention 2016 to 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.

WORKSHOP SUMMARY

Mental health issues affect a significant portion of the world’s population and can result in debilitating and life-threatening outcomes. To address this increasingly pressing healthcare challenge, there is a need to research novel approaches for early detection and prevention. Toward this, ubiquitous systems can play a central role in revealing and tracking clinically relevant behaviors, contexts, and symptoms. Further, such systems can passively detect relapse onset and enable the opportune delivery of effective intervention strategies.

However, despite their clear potential, the uptake of ubiquitous technologies into clinical mental healthcare is rare, and a number of challenges still face the overall efficacy of such technology-based solutions. The goal of this workshop is to bring together researchers interested in identifying, articulating, and addressing such issues and opportunities. Following the success this workshop in the last four years, we aim to continue facilitating the UbiComp community in developing novel approaches for sensing and intervention in the context of mental health.

CML-IOT 2020: 2nd Workshop On Continual And Multimodal Learning For Internet Of Things

https://cmliot2020.github.io

ORGANIZERS

Susu Xu (Qualcomm AI Research, USA), Tong Yu (Samsung Research America, USA), Shijia Pan (UC Merced, USA)

WORKSHOP SUMMARY

With the deployment of the Internet of Things (IoT), a large number of sensors are connected to the Internet, providing large-amount, streaming, and multimodal data. These data have distinct statistical characteristics over time and sensing modalities, which are hardly captured by traditional learning methods. Continual and multimodal learning allows integration, adaptation, and generalization of the knowledge learned from experiential data collected from distributed and heterogeneous IoT devices to new situations. Therefore, continual and multimodal learning is an important step to enable efficient ubiquitous computing on IoT devices.

We aim at bringing together researchers from different areas to establish a multidisciplinary community and share the latest research in continual learning and multimodal learning for various IoT applications.
