Abstract:
The author et al. are currently engaged in a project for an image displaying system with a screen from which smells are discharged for users, together with images, aiming at applying it to digital signage and for other purposes in order to enhance the realistic sensation of the food images. The author et al. conducted experiments in presenting food images and discharging smells from the same position, and analyzed the users’ psychological impact. A subject questionnaire and a cerebral blood-flow meter were used for the analysis. In the first experiment, it was clarified that when an airflow and a smell were discharged in conformity with the image of cooking with a steaming hot pot, an inhaling action occurred and smell perception rate was enhanced. In the second experiment, when a smell fit with a food image was discharged, the realistic sensation and the oxyhemoglobin rose in the vicinity of the temple because the salivation central nerves became active.
