ANTECEDENTES DE LA INVENCIÓN BACKGROUND OF THE INVENTION
Un objetivo fundamental en la mayoría de civilizaciones actuales, es disminuir el analfabetismo entre las personas. Para ello, es importante dedicar tiempo y recursos a la enseñanza de la lectura y la escritura. En este último campo, la etapa inicial de formación en escritura, suele conllevar problemas con la caligrafía debido a un desarrollo limitado de la motricidad fina, especialmente en niños. A fundamental objective in most current civilizations is to reduce illiteracy among people. For this, it is important to devote time and resources to the teaching of reading and writing. In this last field, the initial stage of writing training usually leads to problems with calligraphy due to a limited development of fine motor skills, especially in children.
Actualmente, la tarea de enseñanza de caligrafía requiere en muchos casos la toma de la mano del aprendiz por parte de un tutor, con el fin de guiar el movimiento en el seguimiento de la secuencia de líneas caligráficas hasta alcanzar la destreza necesaria. Esta actividad, en general, requiere una dedicación diaria por parte del tutor. Currently, the task of teaching calligraphy in many cases requires the apprentice to take the hand of the apprentice, in order to guide the movement in the follow-up of the sequence of calligraphic lines until the necessary skill is achieved. This activity, in general, requires a daily dedication by the tutor.
Las soluciones actuales del aprendizaje caligráfico en el momento de iniciación de la escritura se basan en la repetición continua de la secuencia de un patrón escrito en líneas discontinuas, impreso sobre una hoja de papel, consumiendo una o más hojas diarias e incrementando el costo ecológico y la economía familiar. Muchas soluciones actuales se dirigen a la localización mediante distintos medios de un dispositivo tipo bolígrafo en una superficie. Por ejemplo, se han desarrollado dispositivos tipo tableta que hacen uso de un lápiz electrónico para escribir, y permiten conocer la posición del lápiz electrónico con respecto a la superficie de la tableta en cada momento. The current solutions of calligraphic learning at the time of writing initiation are based on the continuous repetition of the sequence of a pattern written in dashed lines, printed on a sheet of paper, consuming one or more sheets per day and increasing the ecological cost and The family economy. Many current solutions are directed to the location by different means of a pen-type device on a surface. For example, tablet devices have been developed that make use of an electronic pen for writing, and allow to know the position of the electronic pen with respect to the surface of the tablet at any time.
Las soluciones encontradas, sin embargo, no permiten guiar y entrenar a un usuario de forma automática en el seguimiento de líneas. The solutions found, however, do not allow guiding and training a user automatically in line tracking.
