Towards computer-based visual perception test for Korean patients with brain injury

Up to now, several tools to evaluate visual perception tests have been introduced for different purposes. However, they were mostly manual tools, paper books in which the therapists would turn the pages while working together with patients. This paper discusses a potential plan to develop motor-free visual perception test software for Korean patients with brain injury, and to construct a centralized database for their evaluated data in a client/server environment. Through its development, we eventually hope to achieve effective management of the data for better understanding of patients' visual perceptual skills and the standardization of the evaluation for Korean patients. With the help of the computerized environment, we also expect some advantages such as acquisition of reliable results from patients with brain injury, automation for storing and accessing patients' data, construction of the patients' database and the management of a vast amount of the data within it and the provision of a foundation to promote further development of various perceptual-cognitive rehabilitation programs.

I. Introduction

Brain injury badly affects human visual perceptual ability. From psychological approaches, visual perceptual skills are taken into account in terms of visual closure, figure-ground discrimination, form consistency, spatial relations, and position in space. Visual perception test tools aid to evaluate visual perceptual skills for patients having brain injury and compare the resulting data with normal persons'.
