The invention relates to a board for blind persons, which makes it easier to write, draw and learn shapes through positive relief elements that can be reused. When writing or drawing, it is possible to check what has been done and to correct errors detected with the fingertip (4). Said board has a grid (3) for picking up, putting down and storing small-size relief elements (1). Said relief elements are placed on a panel (2) with a matrix of holes, forming letters and drawings. There is a means for making copies of what was written or drawn. Drawing tools or stencils that can be attached with pins to the matrix of the panel are provided. Once the activity is finished, there is a means of collecting the relief elements and storing same in the container in the panel or the grid. |
