DeltaVR is a virtual reality experience set in the [Delta Centre](https://delta.ut.ee/) of the [University of Tartu](https://ut.ee/). The virtual Delta Building includes several interactive scenes that demonstrate the teaching and research actively done in the Delta Centre.
The application works on PCVR, Meta Quest 2 and 3, HTC Vive, and regular Windows PC platforms. There is cross-platform multiplayer functionality that enables several users to be in the same virtual environment from both VR and PC platforms.

## Features
### Exploration
DeltaVR features the first two floors of the Delta Educational Building for **exploration and discovery**. There are many diegetic elements representing the studies and research conducted at the Delta Building, such as robotics, the high-performance computing server room, video game development, and student life.
### UFO Bow Game
At the terrace on the second floor, Delta explorers can defend the building from UFO-s using a bow and **achieve high scores**.
### Bolt Self-Driving Car
The courtyard between the Educational and Entrepreneurial buildings of the Delta Centre, the explorers can see the Bolt Self-Driving Car. This car is developed by the [[http://adl.cs.ut.ee/|Autonomous Driving Lab]] of the [[https://cs.ut.ee|Institute of Computer Science]]. If one is brave enough, they can stop the car and catch a ride, simulating both the **feeling of being in a self-driving vehicle** as well as VR motion sickness.
### Interactive Map
To navigate the two floors of the large Delta Educational Building, explorers have an interactive map. This provides a clear overview of where they currently are and what other interactions are located across the building. Explorers can teleport to a **select interactive experiences**, while others are left for them to discover based on the hints on the map.
### Whiteboard
In the virtual Computer Graphics and Virtual Reality Study Lab, explorers can use spray paint cans to draw on a whiteboard. Surprisingly, this is one of the **more popular interactive experiences** of DeltaVR.
