The 3D stereoscopic technique consists in providing the illusional perception of depth of a given object using two different images mimicking how the right and left eyes capture the object. Both images are slightly different and when overlapped gives a three-dimensional (3D) experience. Considering the limitations for establishing surgical…

Extant literature has preliminarily confirmed the potential benefits of holographic projections for educational purposes. Yet, students' experiences of learning by holographic projection have rarely been addressed. The main purpose of this study was therefore to explore students' conceptions of and approaches to learning by holographic projection.…

The article studies the holographic projection technology in an innovative music classroom during full-time education. The study addresses the influence of this technology on the effectiveness and efficiency of learning, as well as on the perception and memorisation of educational material by students. It describes an innovative music classroom…

Perspective is a rich area for mathematical work, and one that should be accessible to many students, since it is based on the everyday experience of viewing the 3D world directly and through familiar 2D representations (drawings, photographs, images on a television or cinema screen, etc). A nice feature of perspective tasks is that they can be…

Describes the development of a three-dimensional projection system used to present structural principles by means of slides. Polarization of images from two planar projectors and viewing through polarized lenses gives stereo results. Techniques used in producing the slides and constructing the equipment are given. (TS)
