Augmented reality visualisation system

As explained in Chap. 3, the aim of the development of the tactile interface is to allow users to perform the tactile evaluation together with the visual one. Thanks to the desktop and portability features of the developed tactile display, the user can use as a visualisation device the monitor of the PC/Laptop, which he/she is using in order to create the digital model. However, Augmented Reality (AR) technology can be used and exploited to create a more immersive experience. AR technology allows us to superimpose a 3D visual representation of the digital model directly onto the tactile interface. In this way, the user can interact at the same time with the tactile interface, in order to perform the tactile evaluation, and with the digital representation of the model shape, thus performing the visual evaluation.
