| Popis: | In a previous study, we have developed a directional volumetric display that handles multiple directional images. To realize a multilingual digital signage system, we implement a language identification function on the directional volumetric display. The language identification (English, Spanish or French) is performed using a convolutional neural network. The discrimination accuracy of the three languages is 91.9%. Combining the language identification function with the directional volumetric display, an image can be directed toward a specific speaker. The result is a multilingual digital signage system that adapts the image presentation to the spoken language. |
