HCI Deep Dives

What happens when you watch yourself perform in VR—and then have to critique that performance? This study explored self-reflection in motor skill learning using a Karate training task. Participants were embodied as a...

Can fake heartbeat sounds trick your body into relaxing? This system generates pseudo-heartbeat audio at rates slightly slower than your actual heart rate to induce calm and support meditation. Using a contactless radar...

Learning to identify musical pitch intervals usually requires tedious rote practice. Purrfect Pitch offers a new approach: a wearable haptic vest that translates sound into touch. When users hear two musical notes, they...

Processing high-resolution video with AI requires massive computational resources. GazeLLM offers an elegant solution inspired by human vision: use eye-tracking to focus only on what matters. By cropping first-person...

Traditional quadrotor drones pose safety concerns with their spinning blades. Cuddle-Fish takes a different approach: a helium-filled soft robot with bio-inspired flapping wings that's safe enough to touch, hug, and...

Our bodies experience a wide variety of kinesthetic forces as we go about our daily lives, including the weight of held objects, contact with surfaces, gravitational loads, and acceleration and centripetal forces while...

Perceiving and altering the sensation of internal physiological states, such as heartbeats, is key for biofeedback and interoception. Yet, wearable devices used for this purpose can feel intrusive and typically fail to...

To enhance focused eating and dining socialization, previous Human-Food Interaction research has indicated that external devices can support these dining objectives and immersion. However, methods that focus on the food...

When several individuals collaborate on a shared task, their brain activities often synchronize. This phenomenon, known as Inter-brain Synchronization (IBS), is notable for inducing prosocial outcomes such as enhanced...
