Neotrie VR

Here’s the same summary with links removed:

What it is

NeoTrie VR is a software that enables users to create, manipulate, and interact with 3D geometrical objects and 3D models of several types. It allows teachers to easily design 3D mathematical activities incorporating text, photos, videos, and sounds.

Who made it

The development team is multidisciplinary, comprising the “Virtual Dor” spin-off and its software engineers, a mathematician specialising in geometry and topology, and two researchers in Mathematics Education. It originates from the University of Almería, Spain.

Platform availability

It is available on Meta Quest and via Steam (as Neotrie VR Multiplayer), and supports mixed reality as well as fully immersive VR.

Key features

Subject coverage includes 2D and 3D geometry (parallels, perpendiculars, angles, lengths, areas, volumes), multiview projection planes and scanner for studying sections and figures, manipulation of round bodies and curved intersections, and construction and study of polyhedra (Platonic solids, pyramids, prisms, antiprisms, Archimedean, Johnson, Kepler, etc.).

It includes a multiplayer tool that enables users to create, play, and learn together in the same scene, plus photo camera and video recording inside the VR scene.

Educational aims

The app aims to develop handicrafts and 3D visual skills, stimulate deductive and inductive reasoning, highlight cooperative work and positive interdependence, and motivate pupils through recreational, collaborative, and competitive games.

Research backing

The software has been developed through a dynamic, continuous feedback process involving a software development company, university researchers, and schools — producing improvements in geometric content, representations, and mathematical activity available to students. It has been trialled in primary and secondary schools across Spain and Poland, and also in undergraduate and postgraduate settings.

Teacher reception

Teachers from the Netherlands report that students aged 12–18 gain a better understanding of 3D mathematics through the VR environment and are able to coach each other during tasks.

Awards

It was awarded at the Science on Stage festival in both 2016 and 2017.
