PURPOSE: A braille-based learning mat is provided to prevent the occurrence of safety accidents by installing an alarming unit at the edge of the mat. CONSTITUTION: A section coordinate generating unit is buried in a mat. If pressure is applied to one section on the front side of the mat, a coordinate contact point signal for each section is generated. A controlling box receives the coordinate contact point signal for each section from the section coordinate generating unit. A learning content corresponding to the coordinate contact point signal for each section is output.
