Auditorily-Induced Vection in VR

We often rely on our audition when evaluating object motion, like, for example, the velocity of an approaching car. Can acoustic cues provide us with information about our motion, real or illusory?

Avatars in Virtual Reality

Avatars are a central component of the virtual reality experience. In this project, we explore avatars' spatial capturing visually and sonically and integrate them into a VR environment. The visual volumetric capturing uses the new Azure Kinect depth-sensing cameras and Depthkit.

Hide and seek - VR Audio Multiplayer Game for Oculus Quest

Hide and Seek is an audio-based VR game strongly inspired by the minigames of Half+Half. The project is meant to be a technical proof-of-concept establishing a Unity VR multiplayer game with voice and sound communication.

Photogrammetry of Acoustics Labs

Goal Create photogrammetric scans of AcousticsLab facilities (10-15 rooms) in Otaniemi, Espoo. Work packages Make scans of the rooms with iPad Clean up scans with 3D modeling software, e.g., Blender Create VR-ready version: smoothing, decimation, re-texturing Hardware iPad Pro 2020 with LIDAR scanner

Ambisonics reproduction in different rooms

The same Ambisonics music can sound very different under different acoustic conditions. Specifically, it has been observed that many pieces sound better in slightly more reverberant rooms than in completely dry reproduction.

Encyclopedia of Artificial Reverberators

Over fifty years, researchers around the globe have developed countless artificial reverberators and among them prominently the Feedback Delay Network (FDN) and its many cousins. Although explicit system architectures are rarely published, nonetheless, there exists a set of notable examples.

Headphones for Mixed Reality

The aim of Mixed Reality (MR) technology is to overlay the physical reality with virtual stimuli indistinguishable from real stimuli. In the visual domains, the main technical paradigms of MR are see-through cameras or transparent glasses.

Optimized Feedback Delay Networks

Feedback Delay Networks (FDNs) are one of the most efficient methods to synthesize artificial reverberation. Although high-order FDNs can achieve high-quality results, they also tend to be too dense and have increased computational complexity.

Aalto Virtual Planetarium

The Aalto Virtual Planetarium is a tour of the inner Solar System, with the grand structures of planetary magnetospheres show through the eyes of a space physicist. Aimed at education and outreach, the immersive virtual reality experience demonstrates Aalto space research, including the plasma physics of the Sun, magnetosphere of inner planets, the Finland100 satellite and cometary environments.

Altered Space: Sound Piece for Virtual Acoustics

Virtual Acoustics (VA), also known as Reverberation Enhancement Systems, are an electro-acoustic setup of multiple loudspeakers and microphones to alter the sonic environment in-situ. While VAs are typically employed to adjust room acoustic parameters for musical performances, in this project, we explore the artistic potential of such systems for immersive storytelling.
