Claim 5:
6. The system according to claim 4, wherein the at least one program is further configured to,
invoke 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;
determine 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;
invoke the display apparatus to highlight a plurality of angular directions in a second direction selection interface in turn, after determining the direction range specified by the user;
determine a currently highlighted angular direction as an angular direction specified by the user, when receiving a determination electroencephalogram signal of the user through the electroencephalogram electrode array;
invoke the display apparatus to display the interaction information inputting interface; and
invoke at least one speaker corresponding to the angular direction 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.
