Virtual Rehearsal
What I worked on—
Project Lead Interaction Design
Marketing
Virtual Rehearsal allows you to simulate your onsite presentation practice in a highly realistic VR environment——and receive valuable Q&A interactions and feedback.
My partner and I led a group of six to develop Virtual Rehearsal, an LLM-integrated VR project that won Best Research at the 2024 Open HCI Student Workshop and was selected for the demo showcase at the 2024 Taiwan Human-Computer Interaction Conference (TAICHI), all within a tight time frame of just 7.5 days during a hackathon.

When you think about public presentations,
how do you feel?
77% of people experience anxiety and fear about public speaking (Fraculj & Kovacic, 2022).
93% of people experience anxiety related to interviews (JDP, 2022).
👨🏻🏫
Virtual Rehearsal is your go-to tool for mock onsite presentation practice.
Practice realistic presentations
anytime, anywhere
Put on a VR headset to immerse yourself in a realistic presentation environment—customize settings, choose venues, manage time with a countdown, and switch slides seamlessly. After your presentation, engage in an LLM-powered Q&A session and receive detailed performance feedback.

Through extensive literature reviews, advisor discussions, and interviews with eight participants, we identified two key sources of anxiety in onsite presentations: live audiences and the Q&A session. Based on these insights, we designed the product with audience avatars that blend LLM and human-controlled avatars. When indistinguishable, these avatars create an exceptionally realistic audience experience.
Blending LLM and live audience avatars—a larger crowd with minimal effort.
