I am investigating the mechanisms of human visual perception using the techniques of psychophysics and brain activity imaging.

In recent decades, information and communication technologies (ICT) have developed markedly. However, electronic devices are not always designed to be human-centric. I am trying to find how to optimize such devices for humans by investigating the human visual mechanisms.

For instance, humans can judge glossiness of objects instantly. We found that humans judge glossiness based on inter-ocular luminance differences and luminance changes accompanying head movements (Sakano & Ando, 2010). In addition, by using this finding, we found that multi-view 3D displays, which present different images depending on the eye locations, are advantageous in glossiness reproduction (Sakano & Ando, 2012). Furthermore, we found that for accurate glossiness reproduction, such 3D displays should have a small viewpoint interval and moderately small crosstalk.

I believe that studying human vision will help ICT designs become human-centric.
