摘要：
Device for determining the near vision for reading / graphics recognition texts of a subject test with a surface (3, 3a) of presentation that can represent a plurality of text / graphics (7) of different font sizes or size and a microphone (9) for recording the expressions of the subject test to read or recognize the text / graphics and a computer system that is configured to monitor the process of reading or recognition based on the records of the microphone and determine depending on the size of text or size used near vision of the subject test used a means to measure the reading distance, which can freely choose the subject of test, from the text or graphic (7) represented wherein the computer system it is configured so that based on a mathematical relationship using the reading distance thus measured and the logarithm of the size of text reaches the reading subject test near vision is corrected to a corrected distance value being the means for measuring the distance of reading a photogrammetric stereo system with two video cameras (11, 11a) and which is designed to determine the position of a reference point in the test subjects face that, then in relation to the position of the display surface, it can be set to calculate the reading distance.Dispositivo para determinar la visión de cerca durante la lectura/reconocimiento de textos gráficos de un sujeto de test con una superficie (3, 3a) de presentación en la que se puede representar una pluralidad de textos/gráficos (7) de distintos tamaños de letra o tamaño y un micrófono (9) para registrar las expresiones del sujeto de test al leer o reconocer el texto/gráficos y con un sistema de cómputo que está configurado para monitorizar el proceso de lectura o reconocimiento en base a los registros del micrófono y determinar dependiendo del tamaño de texto o tamaño utilizado la visión de cerca del sujeto de test utilizándose un medio para medir la distancia de lectura, que puede elegir libremente el sujeto de test, desd
