CHARACTER INPUT DEVICE USING EVENT-RELATED POTENTIAL AND CONTROL METHOD THEREOF |
摘要 |
The present invention relates to a character input device using an event-related potential (ERP) and a control method thereof, and more specifically, to a character input device using a sub-block paradigm (SBP), which is a novel stimulus presentation paradigm capable of solving adjacency-distraction errors and double-flash problems while using a 6×6 character matrix. The character input method using an event-related potential in relation to an embodiment of the present invention includes the steps of: determining a first character to be input by a user among thirty six characters included in a 6×6 matrix; randomly flashing once for each of a plurality of sub-matrixes configured as a 2×3 matrix including six different characters among the 6×6 matrix; counting the number of times of flashes by the user when a first sub-matrix including the first character flashes among the plurality of sub-matrixes; generating the event-related potential (ERP) by the counting operation of the user; and extracting the first character using the generated ERP. |

1. A character input method using an event-related potential (ERP), the method comprising the steps of:
determining a first character to be input by a user among thirty six characters included in a 6×6 matrix; randomly flashing once for each of a plurality of sub-matrixes configured as a 2×3 matrix including six different characters among the 6×6 matrix; counting the number of times of flashes by the user when a first sub-matrix including the first character flashes among the plurality of sub-matrixes; generating the event-related potential (ERP) by the counting operation of the user; and extracting the first character using the generated ERP. |
