Abstract: A video manual generation device includes a document analysis unit, a video analysis unit, a link information generation unit to collect first sets each being a set of a noun and a verb from text information data, to collect second sets each being a set of an object and an action from object information data and action information data, to search those sets for a first set and a second set in which the noun and the object correspond to each other and the verb and the action correspond to each other, and to generate link information data indicating correspondence between a position in the work procedure where the first set obtained by the search is described and a scene in a video that includes the second set obtained by the search, and a video manual generation unit to generate video manual data based on the link information data.

Abstract: A driver assistance device to assist in giving a more appropriate stimulus to a driver is obtained. The driver assistance device includes an acquisition unit to acquire temporal change information indicating a change of a driver's arousal state over time, and a stimulus determination unit to determine a stronger stimulus as a stimulus to be given to the driver as an absolute value of the change over time indicated by the temporal change information acquired by the acquisition unit is larger.

Abstract: A receive terminal includes a quality information determining unit for comparing a value of a quality management parameter group of quality information with threshold data of quality control information stored in a quality control information management unit, and for, when the value of the quality management parameter group exceeds the threshold, carrying out transmission control on the quality information, and a quality management device includes a quality control information management unit for, when determining that a quality evaluation value does not satisfy a predetermined quality level, changing the quality control information.
