| Outline of Final Research Achievements |
Recent advances in three-dimensional (3D) display technology have contributed significantly to society. For example, digital signage is popular. According to the 3D Consortium Safety Guidelines in Japan, a comfortable visual parallax with 3D images is less than ±1.0 degree. However, 3D text must be shown in front of its associated content. We carried out an experiments to verify the permissive limits of cognition in participants regarding the parallax of 3D images. We used 94 participants aged 18 to 81 viewed a 3D flat Maltess cross image having no depth and projected outward from a screen at a large parallax of 1.0 degree to 6.0 degrees. Eighty-six percent of the subjects recognized the 3D flat image even when it protruded at a 2.0 degrees parallax. These subjects viewed the image comfortably and without visual problems. We can conclude that people can cognitively recognize a 3D telop at a 2.0 degree parallax without feeling fatigued.
