  • Patent number: 10795038
    Abstract: An information presentation system according to the present disclosure makes a presentation unit present each of multiple different pieces of information such that an image displayed in a first form and a sound output in a second form are synchronized with each other on an individual basis. The information presentation system also makes the presentation unit shift, when presenting two different pieces of information, selected from the multiple different pieces of information, as two sounds in the second form, a timing to output one of the two sounds by at least a certain period of time with respect to a timing to output the other of the two sounds, in order to prevent the two sounds from overlapping with each other.
