InterView
A platform for VR survey interviews. The participant wears a headset and sits across from the interviewer's avatar; the interviewer works from an ordinary browser. Speech, gaze, posture, hand movement, facial expression and the answers are captured on a shared clock. InterView adds a WebRTC media layer (Janus), a browser-based interviewer console and a token-driven session model to Va.Si.Li-Lab.

ReEmote
Extends the face and hand tracking of Va.Si.Li-Lab with schema-based emotion mappings that affect both avatars and their environments, so users and virtual agents share one emotional expression space. Paper: ReEmote.
Va.Si.Li-ES
The event system of Va.Si.Li-Lab. Events are created and serialised at run time and change situational and
environmental parameters (weather, objects, triggers); users are informed and can take part through voting and
feedback. It ships as its own package, see Assets/Lab/EventSystem/README.md.
Paper: Va.Si.Li-ES.
VR-ParlExplorer
A plugin for Va.Si.Li-Lab that virtualises plenary debates: users interact with virtual members of parliament through LLM-based chatbots. Paper: VR-ParlExplorer.
News in Time and Space
News in Time and Space (NiTS) organises news articles (currently based on GDELT) as a geospatial hypertext on a virtual globe, where users visualise, filter and explore global events and trends. Paper: Geo-spatial hypertext in virtual reality.
Viki LibraRy
A dynamically built library in VR that visualises hypertext systems, with an emphasis on collaborative reading and spatial recall. Paper: Viki LibraRy.
Semantic Scene Builder
A VR-based text-to-3D framework: scenes are generated from annotated text descriptions and corrected by grabbing and moving objects instead of editing annotations. Paper: Semantic Scene Builder.
FraGA
The Frankfurt VR Gesture–Speech Alignment corpus, used for multimodal analyses of head and hand movements in dialogue. Paper: FraGA.
