1. An information display device comprising:
a component extraction unit configured to perform a principal component analysis or an independent component analysis to extract desired components from a plurality of signal waveforms based on detected biological signals;
a sorting unit configured to sort a plurality of extracted results obtained by the component extraction unit in descending order of periodicity and display the sorted results; and
a noise component selection unit configured to receive selection of one extracted result as a noise component from the extracted results obtained by the component extraction unit.
