A hearable device is a wearable computer that is worn on the ear. In addition to offering conventional music listening functions when utilized as earphones, a hearable device can be linked to smartphones and various onboard sensors to recognize user ...

C-Auth is a novel authentication method for smart glasses that explores the feasibility of authenticating users using the facial contour lines from the nose and cheeks captured by a down-facing camera in the middle of the glasses. To evaluate the ...

Virtual Reality (VR) has revolutionized social interactions, but limited field of view (FoV) remains a significant obstacle. Users often fail to notice others within the virtual environment, hindering social engagement. To facilitate initiating social ...

The ring-type devices currently on the market are not typically equipped with authentication. This paper proposes an automatic and continuous user authentication method using active acoustic sensing with a speaker and microphone mounted on the ring ...

Sensing movements and gestures inside the oral cavity has been a long-standing challenge for the wearable research community. This paper introduces EchoNose, a novel nose interface that explores a unique sensing approach to recognize gestures related to ...

To aid smart wearable researchers in selecting optimal ground truth methods for motion capture (MoCap) across all loose garment types, we introduce a benchmark: DrapeMoCapBench (DMCB). This benchmark is tailored to assess optical marker-based and ...

Breaks as discretionary self-interruptions can have beneficial effects on information worker productivity and well-being. This has design implications for potential productivity tools that can assess opportune moments to suggest these breaks. ...

The development of robust, generalized models for human activity recognition (HAR) has been hindered by the scarcity of large-scale, labeled data sets. Recent work has shown that virtual IMU data extracted from videos using computer vision techniques ...

To achieve mid-air interactions for smartphones, acoustic-sensing, a technique using the built-in speaker and microphone of smartphones, is promising. However, detecting hand poses on the near-surface of touchscreens remains challenging due to the ...

The implicit communication of emotional states between persons is a key use case for novel assistive and augmentation technologies. It can serve to expand individuals’ perceptual capabilities and assist neurodivergent individuals. Notably, vibrotactile ...

Previous work has demonstrated that virtual accelerometry data, extracted from videos using cross-modality transfer approaches like IMUTube, is beneficial for training complex and effective human activity recognition (HAR) models. Systems like IMUTube ...

We present HPSpeech, a silent speech interface for commodity headphones. HPSpeech utilizes the existing speakers of the headphones to emit inaudible acoustic signals. The movements of the temporomandibular joint (TMJ) during speech modify the ...

The prospect of learning effective representations from unlabeled data alone has led to a boost in developing self-supervised learning (SSL) methods for sensor-based Human Activity Recognition (HAR). Typically, (large-scale) unlabeled data are used for ...

We propose WeightMorphy, a hand-mounted system designed to improve teleoperation manipulation’s operability and immersive experience by changing the moment of inertia. This system reduces the discrepancy between the shape of the virtual hand and its ...

A wide variety of applications of wearable technology require information about forces and pressures exerted on the body, either by a device (e.g. to sense active wearing periods or to provide feedback to a force-sensitive therapy like compression) or ...

Energy efficiency and low latency are crucial requirements for designing wearable AI-empowered human activity recognition systems, due to the hard constraints of battery operations and closed-loop feedback. While neural network models have been ...

Electrodermal activity (EDA) represents changes in the electrical activity of the palmar skin and serves as an indicator of sympathetic nervous system activity. This paper presents a novel method for estimating attention allocation under divided ...

Fingertip input allows for interactions that are natural, easy to perform, and socially acceptable. It also has advantages in terms of low physical demand, confidentiality, and haptic feedback. In this study, we propose TouchLog, a fingernail-type ...

Growing popularity of wearable haptic devices encouraged researchers to implement on-body interfaces that appropriate different form factors and interaction techniques. Among vibrotactile wearable interfaces, neck-worn devices gathered limited ...

Electrical muscle stimulation (EMS)-based systems have been proposed to assist in the learning of motor skills for piano playing. However, learning effects and retention have not been thoroughly evaluated. To address this, we conducted two user studies ...

As wearable technologies proliferate there is a growing need for compact, easy-to-produce textile-based mechanical actuators. This paper presents a novel coverstitched auxetic actuator using shape memory alloys (SMAs) – which we call the Robo-...

Head-worn displays like Tooz and North’s Focals are designed to be worn all day as smart eyeglasses. When the display is not lit (often to save battery life), the optical combiners may remain visible to the user as an out-of-focus seam or discoloration ...

We propose a novel biometric authentication method that leverages sound leakage signals from hearables that are captured by an external microphone. A sweep signal is played from hearables, and sound leakage is recorded using an external microphone. ...

Canine agility is a rapidly growing sport where dogs and their handlers navigate obstacle courses. Recent studies show that over 40% of all agility dogs suffer an injury while training or competing. By collecting and analyzing sensor measurements from ...
