AUGMENTED REALITY AND VIRTUAL REALITY WITH MOBILE DEVICES

The continuous development of the digital three-dimensional representation now offers new tools and techniques to display and “tell” the cultural heritage. Mobile systems and interactive applications, indeed, allows to interact with the goods showing details, hardly perceptible with a two-dimensional representation as well as information impossible to obtain in the visible range. Virtual reality applications able to guide the user in “worlds” explorable via paths arranged to urge the various interests of a varied public. This work shows a Virtual Reality (VR) and Augmented Reality (AR) applications obtained from 3D data collected with a Z+F 5006h laser scanner. A modern real-time 3D engine lets researchers manage complex three-dimensional models on mobile devices too, giving the ability to navigate data interactively and immersively. The collected data are immersively visualized using a Google Cardboard head-mounted display and a real-time 3D mobile VR or augmented reality application. The project examines the Cappellone degli Spagnoli in the Santa Maria Novella Church in Florence. Users can turn their head 360 degrees and examine every detail of the frescoes as if they were standing in the centre of the chapel. As the application, apart from head orientation, has no other input, this work explores a specific selection mode: by clicking particular points in the chap
