Claim 14:
15. The interaction device according to claim 14, wherein the sound outputting component is specifically used for,
invoking the display apparatus to highlight a plurality of direction ranges in a first direction selection interface in turn, when receiving a starting active interaction electroencephalogram signal of the user through the electroencephalogram electrode array;
determining a currently highlighted direction range as a direction range specified by the user, when receiving a determination electroencephalogram signal of the user through the electroencephalogram electrode array;
invoking the display apparatus to display an interaction information inputting interface; and
invoking at least one speaker corresponding to the direction range specified by the user to output a sound based on the interaction content electroencephalogram signal, when receiving the interaction content electroencephalogram signal fed back by the user with respect to guiding of the interaction information inputting interface, through the electroencephalogram electrode array.
