Case studies — Augmented reality (AR)

The «Green Time Machine» is an interactive 3D presentation based on the «living 3D markers» augmented reality system by EligoVision.

The project was ordered by the All-Russia Exhibition Centre (GAO VVC) for the Vorobyovy Gory Nature Reserve Environmental Education Centre.

This stationary installation was set in the Environmental Education Centre on the Andreyevskaya embankment — an educational museum for pupils.

The «living 3D markers» system is a part of a large educational exposition.

It tells pupils and their parents about Vorobyovy Gory (Sparrow Hills) with the help of stereoscopic 3D visualization.

3D content

The project software includes three-dimensional virtual interactive environment — Vorobyovy Gory Nature Reserve.

The interactive area of the «living 3D markers» augmented reality system is the horizontal part of the model where the «Green Time Machine» augmented reality album is placed, or alternatively 12 plastic markers.

A camera that recognizes markers is placed on top.

The first challenge of the project was to assure «continuity» of the 3D presentation since the installation had to be open every day during working hours of the Environmental Education Centre, and be easily accessible both for organized excursion groups and private visitors with children.

For this purpose we created a 3D screensaver, which displays a virtual fly-through to Vorobyovy Gory, and also twelve 3D photos of the reserve.

You can stop the screensaver at any time by laying down a «living 3D marker» into the interactive area and working with it. The screensaver starts playing automatically 30 seconds after a user takes a «living 3D marker» away from the camera’s field of view.

The project was designed as an illustrative material for four thematic sections, which describe the life of the nature reserve.

They are:

  • Vorobyovy Gory — geological structure;
  • Vorobyovy Gory — flora and fauna;
  • Vorobyovy Gory — architectural heritage;
  • kaleidoscope of Eco-Projects.

Every spread of the album has an augmented reality marker.

All in all we created twelve 3D models. Each of them is linked to its own marker and audio track. Almost all models are animated.

They include:

  • rotating 3D model of the Vorobyovy Gory’s relief;
  • our 30-second 2D cartoon representing all peculiarities of landslides formation on the steep banks of Moscow River; it is shown on a mini TV set on a marker;
  • three colorful slideshows («Red List», «Kaleidoscope of Eco-Projects», «History of Vorobyovy Gory») displayed on mini TV sets;
  • 3D model of a kashubian buttercup flower with animation that shows four stages of the flower's life: from the sprout growth to blossoming and fading;
  • animated 3D model of a tawny owl;
  • Vitberg’s architecture project — 3D model of the Cathedral of Christ the Saviour restored from 1830s drawings;
  • 3D model of the Institute of Librarianship created by a renowned architect I. Leonidov; it was planned to be built on the site of the current ski jump.

Each marker has its own audio file with information about peculiarities of every 3D model in the project.

You can use several markers at the same time, rotate them and move within the interactive area.

EligoVision uses its own software to recognize the augmented reality markers.

The «living 3D markers» augmented reality system by EligoVision allows modeling any theme-based application.

Installation

The project hardware is an interactive visual 3D solution, which includes:

  • interactive «living 3D markers» system: a camera, a set of markers, a graphics workstation equipped with a professional video card such as NVIDIA Quadro FX 5800, a 28-pages album; created according to the Brand book of the Vorobyovy Gory Nature Reserve;
  • autostereoscopic Philips WOWvx display (42').
