Innovations in Geometry Teaching with MiritiBoard VR 2.0 Glasses: Customizations and Usability Evaluation

The use of Virtual Reality (VR) headsets has rapidly expanded into various areas, going beyond entertainment and electronic games. These devices provide immersive experiences that simulate three-dimensional environments, allowing for greater user interaction and engagement. Given the growth of mobile VR, this study presents MiritiBoard VR, a low-cost headset made from miriti, a plant native to the Amazon, focusing on sustainability, promotion of the local bioeconomy, and geometry education for basic education students in Brazil. The device was used in the educational application GeoMeta, enabling the visualization of 360-degree content, Augmented Reality, and gamification for geometry teaching. In order to improve the user experience of the MiritiBoard VR, two prototypes with controllers were developed to offer more features and comfort to the glasses, as it has limitations in mobility and interactivity. One prototype has a control integrated into the viewer and the other uses an external GamePad, both connected via Bluetooth, which is housed inside the headset. The evaluation, conducted using the System Usability Scale (SUS), showed that although the conventional model achieved the highest overall score, the MiritiBoard with integrated control was the users' preferred choice. The results indicate that MiritiBoard VR offers an immersive experience comparable to more expensive devices, with potential for expansion through new sensors. In addition to contributing significantly to mathematics education, the project reinforces responsible consumption practices and supports the local Amazonian economy.
