Question

Melisa Ulutas ISLE 7.8 1. What does the horopter represent? 2. What happens to objects in front of or behind the horopter in terms of how they are mapped on to the retina (e.g., what is crossed/uncrossed disparity?) 3. What happens to the eyes as the fixation point moves closer or farther? (describe how the eyes change position)

Answer 1

ANSWER ;-

1.THE HOROPTER IS THE LOCOUS OF POINTS IN SPACE THAT HAVE THE SAME DISPARITY AS FIXATION .THIS CAAN BE DEFINED THEROTICALLY AS THE POINTS IN THE TWO RETINAS , THAT IS AN ANAMATICALLY IDENTICAKL POINTS . THE HOROPTR CAN BE EXTENDED AS A GEOMETRICAL LOCUS OF POINTS IN SPACE WHERE A SPECIAL CONDITION IS MET

2 .WHEN WE LOOK AT AN OBJECT WITH TWO EYES , WE PERCEIVE IT AS SINGULAR LIKE WE DO OTHER PARTS OF THE VISUAL SCENE STIMULATING POINT ON OUR RETINA THAT SHARE A COMMON VISUAL DIRECTION

3. OUR EYES WILL CONVERGE LESS OR FARTHER OBJECTS AND COVERAGE MORE FOR CLOSER OBJECTS ... DURING A SACCADE . IF THE NEW FIXATION , THEN NEW VERGENCE MOVEMENT WOULD ALSO OCCUR TO CORRECT THE ANGLE BETWEEN THE EYES TO FOCUS THE ANGLE BETWEEN THE EYES TO FOCUS ON THE RIGJT DEPTH
