Abstract
We surveyed needs of elderly drivers by a questionnaire. The questions were “How do you feel you become elderly especially in driving?”, “Which scenes do you feel stress during driving?”, “Which driving assistance system do you need?”, and so on. From the results, it was revealed elderly drivers were conscious of visual depression, they felt stress in night driving, and they selected the night vision system as a key assistance. So we made elderly and non-elderly drivers experience one of the existing night vision system to obtain feedback. Despite non-elderly drivers assessing the device helpful, elderly drivers assessing it unhelpful. Elderly drivers couldn't use it because of their physical depression, especially in visual functions. Therefore, we examined the new night vision system that is adapted for characteristics of elderly drivers.
