  • Designing the classroom of
  • tomorrow

The EXPLOAR project usingAugmented Reality Technology (AR)to connect formaland informal learning environments Inspiring Science Learning inScience Museums and Centres by 4. Aims & Objectives

  • Engage visitors of science museums & science centers inextended episodes of playful learning
  • Facilitate lifelong learning by providing a free-choice learning environment
  • Provide pointers for future developments for curators & developers of digital technologies for museum learning
  • Create virtual learning communities of museum visitors
  • Raise the wider publics interest and awareness in science


  • The EXPLOAR system is designed to provide3D graphics
  • superimposed on the users field of visiontogether with
  • other multimedia information, thusallowing to extending
  • the real exhibits with virtual objects.

The EXPLOAR system 6.

  • This is particularly powerful for visualizing complex concepts in physics
  • that are fundamental yet imperceptible (such as electric or magnetic
  • fields, forces, etc).

The EXPLOAR system 7. Virtual Science ThematicPark (VSTP)

  • Mobile Augmented Reality (AR) System
  • Possibility to: a) layer real objects with virtual ones
  • b) place information into real surroundings
  • The CONNECT Platform (CP)
  • Web-based application that enables the:
  • a) distribution of information and organization of educational activities (pre- & post visit activities)
  • b) coordination of educators, visitors and museum staff in the use of innovative technology

8. CONNECT EXPERIENCE 9. Visual Designer (VD)(authoring tool for AR Unit)

  • The VD allows the educator to specify (through a collection
  • of rules) the visual augmentations the visitor can see with
  • the AR unit.
  • The visitors actions indicate to the system when to react.
  • The reactions are presentations of multimedia content
  • (images, sound, text, video or 3-D objects)
  • Additional conditions (statements) might be built such that
  • the AR unit presents the info when the condition is true

The project's vision

  • We should point to a
  • hybrid classroomthat
  • builds on the strengths of
  • formal and informal
  • teaching and learning
  • strategiesin ways that can
  • supportlearning of all
  • students .
