Visuo-haptic uncanny in VR
Visuo-haptic uncanny in VR
Visuo-haptic mismatch in VR can induce discomfort similar to the uncanny valley effect.
The research systematically manipulates delay and force gaps between vision and touch.
Physiological signals (HRV, EMG, skin conductance, pupil dilation) are used to quantify discomfort.
The goal is to build a predictive model and design guidelines for emotionally congruent VR systems.
Magnification illusion
Magnification illusion
When we look at the two lines from the telescope, we see the illusion of two lines; instead of being converged at the far end, it reverses the perspective. We have been doing experiments to prove the cause of this visual illusion.
Remote stress measurement
Remote stress measurement
Being able to track stress levels without any contact-based sensors is important, especially in fields like medicine, mental health monitoring, and human-computer interaction. Our research focuses on creating artificial intelligence techniques that use cameras to monitor stress remotely by analyzing changes in different modalities such as facial expressions and pulse rate.
Real vs Virtual Reality
Real vs Virtual Reality
VR enables real-time interaction, allowing clients to explore and give instant feedback on design elements, leading to efficient decision-making and increased satisfaction for both designers and clients.

VR-CBT
VR-CBT
In today's society, anxiety is widespread, and therapies using VR and CBT are popular. VR therapy offers immersive experiences for confronting anxiety triggers at low risk and cost, while CBT targets negative thought patterns. We proposed a VR-CBT system where users confront virtual anxiety triggers. Our study is trying to validate the effectiveness of interactive VR-CBT interventions for anxiety.
Hybrid image
Hybrid image
A hybrid image is an image that changes the content by the viewing distance. Our lab has successfully combined two different shape images into a hybrid image (above is a cat and car; try viewing very close or very far to see the other image); we are working on combining more than two images. The image is created by interplaying with the image frequency using the image processing technique. This technique, rooted in vision science, reveals how human perception processes spatial information.
