BRAIN: Pseudo-holographic Displays as Teaching Tools in Mathematics

A pseudo-holographic display is a display that creates a virtual three-dimensional image of an object, producing viewing experiences that are virtually indistinguishable from viewing a true hologram.

In the upcoming issue of BRAIN Journal the researchers Monica Ciobanu, Antoanela Naaji, Ioan Dascal, and Ioan Virag will present in their paper “Pseudo-holographic Displays as Teaching Tools in Mathematics” an innovative approach for the education system. This team of researchers came up with the idea of creating and implementing a set of interactive teaching tool packages (ITTPs) to help students grasp abstract mathematical notions by linking them to a specific physical representation.


Modern education led to the development of online courses which are highly advantageous in terms of flexibility, knowledge achievement and costs. Joining ICT with the learning process motivates learners and offers skills that sometimes lack resources in traditional education .

Given the potential and the benefits of e-learning platforms, the researchers created and implemented a set of courses for mathematical disciplines, containing both theoretical modules and applications. The courses were developed as interactive teaching tools packages and they cover topics like mathematical analysis, probability, numerical calculus, computational algebra, linear algebra and analytical geometry. Moreover, all of the developed applications are open-source.

For some applications they used an autostereoscopic display for visualizing 3D objects as pseudo-holographic images. This new approach differentiates their tools from other existing contributions and facilitates the understanding of mathematical abstract notions by combining theory with interactive applications.

The full article along with a more detailed insight on how this set of interactive teaching tool packages was designed will be published in the upcoming issue of BRAIN Journal.
