A method, apparatus and computer program are provided. The method comprises: performing a first detection of at least one bio-signal from at least one user; controlling a user output device to initiate a user alert, after performing the first detection of the at least one bio-signal; performing a second detection of the at least one bio-signal from the at least one user, after initiating the user alert; and processing the first detection of the at least one bio-signal and the second detection of the at least one bio-signal to determine whether one or more changes in the at least one bio-signal pass a significance test. |
