Resumen
This paper study the visual sphere based on a visual surface from a patients' point of view in immobile condition. Capturing image and calculating region were used to identify visual sphere as a collected scene, that established a coordinate system, based on visual degrees in seeing capacity. Coordinate system reveals the most effective of series of the scene in a coordinate mapping of the visual sphere. The most effective of series of the scene will identify the maximum level of seeing capacity. These findings provide new evidence to improving interior design for inpatients in the hospital.
