An operational support apparatus for supporting operation of a display apparatus, the display apparatus including a plurality of input terminals that each receive image information and a display section that displays image information received by an activated input terminal of the plurality of input terminals from an apparatus connected to the activated input terminal, comprising:
- a speech recognizer that converts speech data into text information;
- and
- a command generator that generates a control command that corresponds to a content of the text information,
- wherein in a case where the text information contains a keyword that indicates first application software, the command generator determines which of the plurality of input terminals of the display apparatus is associated with the first application software,
- the command generator generates, as the control command, a switching command to activate the input terminal thus determined and a start-up command to start the first application software associated with the input terminal thus determined,
- the command generator identifies a certain input terminal of the input terminals of the display apparatus according to a keyword that indicates first application software associated with the certain input terminal, and identifies a certain different input terminal of the input terminals of the display apparatus according to a keyword indicating first application software associated with the certain different input terminal, and
- first application software associated with an input terminal of the input terminals activated by the switching command is installed on an apparatus connected to the input terminal activated by the switching command,
- after the first application software associated with the input terminal activated by the switching command is started by the start-up command, the apparatus connected to the input terminal activated by the switching command transmits image information generated by the first application software associated with the input terminal activated by the switching command to the input terminal activated by the switching command.
