Explainable AI (XAI) has established itself as an important component of AI-driven
interactive systems. With Augmented Reality (AR) becoming more integrated in daily lives …

Past research regarding on-body interaction typically requires custom sensors, limiting their
scalability and generalizability. We propose EarBuddy, a real-time system that leverages the …

Face orientation can often indicate users' intended interaction target. In this paper, we
propose FaceOri, a novel face tracking technique based on acoustic ranging using …

We propose HeadCross, a head-based interaction method to select targets on VR and AR
head-mounted displays (HMD). Using HeadCross, users control the pointer with head …

Input recognition errors are common in gesture-and touch-based recognition systems, and
negatively affect user experience and performance. When errors occur, systems are …

Influential theories in psychology, neuroscience, and economics assume that the exertion of
mental effort should feel aversive. Yet, this assumption is usually untested, and it is …

Personalized document recommendation systems aim to provide users with a quick shortcut
to the documents they may want to access next, usually with an explanation about why the …

We propose Auth+ Track, a novel authentication model that aims to reduce redundant
authentication in everyday smartphone usage. By sparse authentication and continuous …

Flipping is a potential interaction method for dual-display phones with front and rear
screens. However, little is known about users' phone flipping behaviors. To investigate it, we …

Modern information querying systems are progressively incorporating multimodal inputs like
vision and audio. However, the integration of gaze---a modality deeply linked to user intent …
