Nagoya University Miyao Laboratory 3D Related Literature Collection: Simultaneous Accommodation and Convergence in Natural Vision
Simultaneous measurement of accommodation and convergence in natural vision.
In recent years, three-dimensional imaging has rapidly spread in society, with opportunities for the general public to experience it through 3D movie screenings and the sale of 3D televisions becoming more common. Electronics manufacturers are strengthening their products by focusing on 3D-related features as a highlight of digital devices, anticipating market expansion. Despite this widespread adoption, the effects of stereoscopic vision on human visual function have not yet been fully understood. Considering the safety of three-dimensional imaging, it is extremely important and essential to examine its impact on the human body.

basic information
【Features】 ○Subjects: An experiment was conducted on seven young individuals (ages 20 to 37). ○Experimental Method: Subjects were either uncorrected or fitted with contact lenses, with refraction corrected to within ±0.25 diopters (1 subject uncorrected and 6 corrected with contact lenses). ○Measurement Equipment: The measurement was conducted using a transmissive accommodation measurement device manufactured by Grand Seiko (binocular auto-refractor keratometer WAM-5500) and a device capable of measuring reproduction distance manufactured by Nack Image Technology (EyeMark Recorder EMR-9). These two devices were combined as shown in Figure 3 to simultaneously measure the focal lengths of accommodation and convergence when the subjects were viewing an object. ●For more details, please contact us or refer to the catalog.

Company information
With the development of the information society, "information" has now become an important element that constitutes human society alongside material and energy. In this graduate school, we capture "information" from various perspectives such as engineering, natural sciences, computer science, humanities, social sciences, cognitive sciences, and life sciences, aiming to systematize "information" as an academic discipline and create new fields through the fusion of these areas. Our educational objective is to cultivate deep knowledge and exceptional abilities required for professions that demand high levels of expertise, through education and research on both the theory and application of information science, contributing to the advancement of culture, and training researchers, highly specialized technicians, and educators in information science. Furthermore, our fundamental policy is not only to develop the ability to conduct cutting-edge research in information science but also to nurture individuals who understand the characteristics of society and culture and possess a social ethical perspective, engaging in comprehensive educational and research activities that incorporate various new initiatives.
