This study aimed to reveal normative precautionary observation for crossing bicycles when turning left at signalized intersections. We analyzed eye movement data of a driving instructor when he drove a vehicle equipped with a driving recorder and four cameras, Through conducting hearing survey with the recorded images and analyzing the experimental data, we concluded that the instructor assumed crossing bicycles closed to a pedestrian crossing from four directions and he checked the existence of crossing bicycles by three steps. Finally, we revealed the sequence of normative precautionary observation which could prevent the accidents with crossing bicycles in all directions.

We compared 3D image quality of the three different types of 3D televisions by the method of paired comparison. Three 3D video clips were used for evaluation. The results indicated that the lenticular glassless 3D television was the lowest total image quality. In two of three video clips, there were no significant differences between the polarized glasses and the active shutter glasses. Factors affecting subjective image quality of 3D televisions were discussed.
