The increasing diffusion of augmented reality applications, fostered by the commercial availability of see-through enabled head mounted displays, is opening new opportunities to exploit the potential of this technology to aid subjects with visual impairments in their everyday tasks. The capability of showing a corrected version of the visual field by means of real-time processing of a video stream representing the surrounding environment, is the foundation of the proposed method to compensate a serious visual deficit, known as metamorphopsia, resulting in a geometrical deformation of part of the subject's visus. To this regard, we describe an approach for interactive measurement of user's impaired visual biometrics and for real-time compensation or reduction of this deficiency. This goal is achieved by mapping the video streams acquired from the stereoscopic video see-through cameras each onto a 2D polygonal mesh and offsetting its vertices until the correct vision, for each eye, is restored.

Abstract
The increasing diffusion of augmented reality applications, fostered by the commercial availability of see-through enabled head mounted displays, is opening new opportunities to exploit the potential of this technology to aid subjects with visual impairments in their everyday tasks. The capability of showing a corrected version of the visual field by means of real-time processing of a video stream representing the surrounding environment, is the foundation of the proposed method to compensate a serious visual deficit, known as metamorphopsia, resulting in a geometrical deformation of part of the subject's visus. To this regard, we describe an approach for interactive measurement of user's impaired visual biometrics and for real-time compensation or reduction of this deficiency. This goal is achieved by mapping the video streams acquired from the stereoscopic video see-through cameras each onto a 2D polygonal mesh and offsetting its vertices until the correct vision, for each eye, is restored.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
