Ameliorating Visual Field Disturbance by Adaptive Alpha Blending of Full View and its Evaluation in Terms of Visual Field Characteristics

Abstract

As of this moment，it is argued that there are about 285 million patients with visual impairment in the world and about 60 million patients among them suffer from visual field disturbance. The prior approaches to assisting the patients with visual field disturbance rely mostly on non-visual sensation. In contrast，a vision assistance method proposed in this research attempts to superimpose judiciously processed surrounding scene onto the limited visual field of the patients. This article reports main results of preliminary evaluation experiments on the proposed method. The design of sophisticated experiments focusing on the characteristics of ameliorated visual field is also discussed.
