Lecture 1: "Wear-to-compute? Challenges of earable computing for health" 8:15–9:00

Speaker: Prof. Cecilia Mascolo (University of Cambridge, UK)


Earable devices are pervasive in our lives, they accompanying us in every virtual meeting or while we are running. These devices are becoming, in theory, very good proxies for human behaviour. Yet, making the inference from the raw sensor data to individuals’ behaviour remains difficult. In this talk I will discuss and highlight the open challenges that these technologies still face before they can be trusted health measurement proxies. Namely, the ability to work in the wild, the sensitivity of the data versus centralisation of computation, the uncertainty of the prediction over the data. I will use examples from my group's ongoing research on on-device machine learning, earable sensing and uncertainty estimation for health application in collaboration with epidemiologists and clinicians.

Lecture 2: "Sensing and Stimulation with Earable Devices " 9:00–10:00

Speaker: Prof. Tam Vu (CEO, Earable Inc. and University of Colorado Boulder, USA)


This talk discusses Earable computers as sensing and actuating devices that are worn inside, behind, around, or on users' ears for sensing many important physiological signals such as the brain, eyes, facial muscles, heart rate, blood pressure, core body temperature, and more. These signals could enable a wide range of applications from human-computer interaction, to health care, attention/focus monitoring, and opioid use reduction. Drawing the analogy from the evolutions of mobile systems and wearable systems, in this talk, I will discuss the opportunities that earable systems could bring. I will share our experience and lessons learned through realizing such earable systems in the healthcare context, from research to commercialization.

Coffee Break 10:00–10:15

Lecture 3: "Leveraging Earables for Unvoiced Speech and Beyond" 10:15–11:00

Speaker: Prof. Shubham Jain (Stony Brook University, USA)


Modern environments are alive with sensors, such as smartphones, watches, earphones and other wearables. However, despite the plethora of sensors, technologies supporting the disabled population are still scarce. This is primarily due to the difficulty in direct sensing of desired events in the real-world. We believe that earables are the next frontier in passive sensing that offer a novel interaction modality and can provide a range of services to a diverse population. This talk will explore our research efforts in leveraging the inertial sensors on earables to interpret unvoiced or silent speech. Not only is this a privacy preserving interaction modality, but it holds great promise for those with speech disabilities.

Lecture 4: "Revisiting a Few Classical Problems in the Context of Earable Computing" 11:00–12:30

Speaker: Prof. Romit Roy and Yu-Lin Wei (University of Illinois Urbana-Champaign, USA)


The rapid advances in speech recognition, NLP, and human-centric sensing make the earable platform a launching pad for many new technologies and applications. On the other hand, earables also encapsulate a much higher information density, complexity, and constraints, compared to other mobile devices. In this talk, we will revisit classical problems under the new challenges brought by the earable computing platform. For instance, how could we estimate multiple angle of arrivals (AoAs) in a heavily reverberated environment? How could we separate multiple ambient signals with a few microphones? How could we locate and calibrate a user’s location without help from other infrastructure? This talk will take quick glimpses on classical approaches in each of these topics, and then discuss some new ideas (both algorithmic and deep-learning-based) for the special case of earable computing.

Lunch Break 12:30–1:15

Lecture 5: "Multimodal and Transfer Learning for Fine-Grained Human Facial Sensing Using Earables" 1:15–02:00

Speaker: Prof. VP Nguyen (University of Texas at Arlington, USA)


In this talk, I will discuss an important emerging research topic of developing a socially-acceptable earable system that can unobtrusively, continuously, and reliably sense human facial activities in fine-grained. Building such a system requires answering many important questions. For example, where do we place sensors or electrodes? How many sensing modalities, electrodes, or channels are sufficient? How do we select the best combination of sensors, electrodes, and channels for the desired applications? How can we adaptively optimize the contributions of each sensing input? Can we allow sensing modalities to learn from each other to enhance accuracy? Can the knowledge be transferred from high-dimensional data to one or few dimensional data? This talk will describe the roles of multimodal and transfer learning in addressing these important questions. I will then discuss our experiences and lessons learned in developing novel algorithms to allow earables to reliably track 3D facial activities and face-hand interaction. I will close the talk by presenting other opportunities that the proposed techniques could bring to earable research and challenges that need to be addressed to unleash their potential.

Lecture 6: Robust Sensing and Efficient Computing for Intelligent Biosignal-based Earables. 02:00–02:45

Speaker: Nhat Pham (University of Oxford, UK)


Earables have great potential in enabling various healthcare applications due to their close proximity to multiple sources of critical head-based biosignals such as EEG, EOG, EMG, and EDA originating from the brain, eyes, facial muscles, and sweat glands, respectively. However, there are several fundamental challenges to realize their potential, such as (1) how we can capture biosignals reliably given the noisy environments and (2) how we can optimize the system to ensure high-fidelity signals while being energy-efficient for prolonged usage. This talk will discuss our recent research efforts in hardware and software techniques to overcome these challenges. We will also take a glimpse on the potential use cases such as microsleep detection or long-term epileptic seizure monitoring.

Lecture 7: "Programming Earable BrainBand Made Easy" 02:45–04:30

Speaker: Galen Pogoncheff ( and Vinh Nguyen (


This talk presents Earable BrainBand - Frenz - from a researcher's perspective and a live-coding demo. We present technical details of Earable Brainband, the data that we receive, how it can be used in research, the current set of available features, etc. We then do a live implementation of 3 simple demos that highlight relevant ideas for researchers. In this live coding session and demo, we will show a basic setup for connecting to a band with a bluetooth connection, starting data streaming, preprocessing the raw signals, and visualizing the signals in real-time. Since a lot of prospective researchers desire the ability to collect signal data directly from the device, this will be a very important feature of our SDK to show. We will then expand upon this code, demonstrating facial gesture detection and focus. Each of these features should be associated with an associated visual that keeps the audience engaged.
