EyeLingo: Unknown Word Detection for English as a Second Language (ESL) Learners Using Gaze and Pre-trained Language Models
This paper presents a transformer-based machine learning model that aligns gaze trajectory with corresponding text and decodes the probability of unknown words within the text in real time with high precision. 
FlowRing: Integrating Microgestures and Surface Interaction for Seamless XR Input
FlowRing enables both quick, discreet in-air microgestures (left) and precise on-surface interactions (right), allowing for always-available, ad-hoc interactions. Such a peripheral could control wearable devices quickly like changing earbud volume while on-the-go or be used to control an immersive desktop environment in a mixed reality headset.
Tracking Head Position and Orientation Using Acoustic Ranging
FaceOri tracks user’s face orientation towards the device with acoustic ranging using microphones in an earphone. 
AcousLink: Ad-hoc Ultrasonic Ranging Method and Applications
AcousLink enables ad-hoc calibration-free unltrasonic ranging via bluetooth. 
Facilitating Gaze-based Unknown Word Detection Using Pre-trained Language Models (PLMs)
Our method locates the content the user is reading in real-time through gaze, and inputs the gaze data and text data to the transform-based model to detect unknown words. 
Smart Frisbee: Analyzing Data on Throws, Catches, and Player Performance Using BLE and IMU on a Frisbee and Wristbands
The Smart Frisbee project aims to address the limitations of traditional Ultimate Frisbee games by utilizing Bluetooth and IMU sensors in a smart frisbee and wristbands to collect and analyze data on throws, catches, and player performance. This data will be used to provide automated tracking, feedback, and analysis capabilities, enabling players to identify areas for improvement and enhance their gameplay experience.
