Abstract: 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.

Abstract: The present invention relates to a thermal imaging system capable of tracing a specific portion in a thermal image and a method of tracing a specific portion using thereof. The thermal imaging system includes a thermal imaging camera; an imaging camera installed to be adjacent to the thermal imaging camera; and a position measurement apparatus installed to be adjacent to the thermal imaging camera in order to measure photographing positions of the thermal imaging camera and the imaging camera. Therefore, a specific portion of the subject that is difficult to recognize in the thermal image with naked eyes is recognized by contrasting the specific portion in the thermal image with a corresponding portion in the normal image, and thus a correct temperature can be extracted by tracing the specific portion in the thermal image in real-time.
