Co-curation of virtual exhibition at Ars Electronica Festival 2020 In Kepler’s Gardens (September 9-13, 2020). The exhibition involved 21 artists and consisted of 11 virtual environments developed in Mozilla Hubs.

Exhibition text

WADS (↑ ← → ↓) speaks of plurality and plentifulness, of conjoining principles, disciplines and possibilities. As a virtual space compiled of local artists, it sets out to explore the potential of digital hubs as grounds of artistic and technological co-creation. It imagines a garden of commoning where artists pollinate the digital by employing a technique derived from gardening: namely, grafting.

In this spirit and following its own mission, RISE invites local artists to pollinate the digital by employing a technique derived from gardening: namely, grafting. WADS, a digital garden of commoning formed by 21 local artists, sets out to explore the potential of digital hubs as grounds of artistic and technological co-creation. The digital exhibition is created and experienced in the online environment of Mozilla Hubs and will be accessible through the Ars Electronica Digital Platform.

Project presentation

WADS was exhibited at the Thinker Maker Space in Nicosia, on October 15-16, 2020.

Sound Spatialisation in Immersive VR Environments

Fri, 06 May 2016 16:30:42 +0300

Duration: May 4-6, 2016.

Exhibition: 16:00 May 6 2016, Le Commun, Geneva.

Workshop brief
Translating sound from the auditory to the spatial domain, and shifting between perceptive forms and media, we intend to explore the manifestation of sound in space. The workshop will focus on the spatialisation of sound in a Virtual Reality setting. The setup includes head-mounted displays to create the -illusory- perception of presence in a virtual space, and Kinect sensors to scan and correlate one’s position from the real to the virtual space. The workshop aims in creating spatial duals of sound as distinct perceptual perspectives or modalities of the same object. We intend to challenge participants to think of how sound could be transferred and experienced in a different medium, as a modulating or formative force on space.

Shifting perspectives

Mon, 10 Nov 2014 11:03:03 +0300

Shifting perspectives is an interactive kinetic installation prototype for projection mapping developed in 2014 between Zurich and Delft with Demetris Shammas, Achilleas Xydis, and Mariana Popescu (as PUNCH Collective).

The installation is a kinetic 6×4 grid structure used as a canvas for interactive projection mapping. The structure consists of 24 square panels assembled with rotary joints, so that when pulled appart the panels rotate individually and the whole structure expands. The movement of the structure is controlled by stepper motors that pull the structure from 2 external points. The three custom software developed for the installation were: a Processing-Java program for real-time sound analysis (FFT); an Arduino-based software for controlling the stepper motors; and a Unity program for projection mapping, all synchronized with each other via OSC. Using real-time sound analysis the installation projected audio-responsive graphics mapped on the continuous movements of the grid structure.

Shifting perspectives was developed in Zurich, fabricated and assembled in Delft for the event 7 Sins, in November 2014.

project Anywhere

Fri, 07 Nov 2014 18:04:19 +0300

The ultimate display would, of course, be a room within which the computer can control the existence of matter.
(Ivan E. Sutherland, The Ultimate Display 1965)

project Anywhere is a framework and proof-of-concept prototype for full-body interactive wireless VR, developed at the Chair for CAAD, ETH Zurich in 2014, to investigate notions of virtual space and time, and to explore designing synthetic spatiotemporal sensory experiences. The project was initiated in mid-2014, following the release of the first commercial VR devices that featured limited bodily involvement and capacity for movement. Addressing these limitations, this project developed a VR framework consisting of a mobile application, custom wireless VR HMDs and data glove prototypes as well as skeleton tracking, to produce a vivid real-time interactive presence in a virtual reality environment In that, project Anywhere demonstrates the potential of virtual space as a valid architectural medium in itself (instead of its use as an intermediary form for design or visualization), that allows experimenting with synthetic kinaesthetic, visual and auditory sensory experiences. Concurrently it explores the capacity of designing spatiotemporal environments with an embedded dimension of time. The project’s title, “Anywhere”, refers to the generic nature of the digital-virtual environment that can be made to simulate any physical context: real or imaginary.

Project description

The project consists of the following bespoke software and hardware prototypes:

a mobile multiplayer VR app,
Omnimask: a 3D printed mobile VR head-mount ,
Inteligloves: a pair of custom wireless data gloves, and
Omnitracker: a sensor fusion software.

The main component of the project is a custom mobile application (1) developed in Unity as a multiplayer VR videogame. Mounted on a VR mask (2), the app provides a stereoscopic viewport for each individual user, through the point of view of their avatar in the shared virtual environment.

Each user’s spatial presence is tracked in real-time by their head-mount, data gloves, and a Kinect skeleton tracking sensor. Cumulatively, head, gesture and skeleton tracking provide 86 degrees of freedom, fused together by the Omnitracker (4), a software written in Java/Processing. These data are synchronized with a web cloud and are use to animate the user’s avatar in real-time (see image13).¹ Thus, any movement of the subject in physical space, such as walking, or even head tilting and finger movement correlates 1:1 to movements of their avatar.

Hardware prototypes developed for this project include a 3D printed VR head-mount (2) and a pair of data gloves (3). The VR head-mount was designed for an iPhone 5, and featured adjustable inter-pupillary distance, and focal length.
The data gloves (3) were developed using Arduino microcontrollers. Each glove features an XBEE transceiver module, a 9 DoF sensor, and up to 6 flex sensors (for tracking individual finger movement). These were mounted on a lightweight elastic 3D printed glove base, easily adjustable for different hand sizes. The framework was programmed to recognize hand gestures, used for performing various contextual virtual actions (see for example image 8), proving that a virtual presence can also be an active one.
