      <abstract>
        <p>Due to the importance of primary education to acquire basic knowledge, it is necessary to use technological tools that allow students to provide their knowledge through educational games and that allows generating the necessary feedback to know the level they are. Using interactive toys implies developing basic skills in learning, necessary for the integral development of students. The present investigation develops an interactive toy that measures the attention, memory and logic of primary level students; Through the Sphero and the Neurosky MindWave, the speed will depend on the attention that the user has, instead the logic and memory measurement is developed with the help of a 6X4 track, the control panel and a mobile application showing the logic and memory questions. The results show that 5th and 6th-grade students of both genders have fun learning and take interest in interactive toy, strengthening logic, memory and attention through the use of technological equipment.</p>

        The training of primary education students is of the utmost importance due to the
rapid development of capabilities and abilities, mental, cognitive, psychomotive,
social and affective [
        <xref ref-type="bibr" rid="ref1">1</xref>
        ]. According to [
        <xref ref-type="bibr" rid="ref2">2</xref>
        ] the children like to play with someone or
have fun with a game that implies a challenge. In child psychology [

        ], mention the
importance of the interactive toy that will be able to develop the cognitive and
affective part of children.
      </p>
      <p>
        Currently, there is a great diversity of interactive and technological games that
allow activating different cognitive areas of children, constituting a key part in its
integral development [
        <xref ref-type="bibr" rid="ref4">4</xref>
        ]. Playing is no longer considered as a pastime, but allows the
child to discover, interact, explore and experience with movements, sensations that
form a concept in the world [
        <xref ref-type="bibr" rid="ref2">2</xref>
        ], [

        Since the mid-2014, the Arduino plate became well known because it allows to
develop several innovative projects and provide customized solutions according to the
situation raised, several projects have been created that allows to encourage the
education of children [

        ].
      </p>
      <p>The proposal aims to capture attention, strengthen the memory and logic of
students, through an interactive toy; Which, through a mobile application developed
on Android, answer the questions, return the attention values and, on the web page,
you will register to users and generate the appropriate reports. Additionally, the
proposal has a physical control command that allows to move the toy car by means of
a 6x4 track with obstacles. Finally, to capture attention to the Neurosky MindWave
will be controlled by the Sphero that is a device in the form of a sphere that has
wireless connection.

        Although E-Learning has many advantages for students and teachers, it brings
with many challenges also, since the teacher cannot monitor whether students are
paying attention, that is why [

predicts video based on emotion, by a Neurosky brain wave detector to predict
appropriate adolescents. Neurosky can also be used in areas of health and
entertainment as they report in [

      <title>Tests</title>
      <p>Project tests were made in three educational institutions with a total of 104
students, in two parts:
- The memory and logical of the students are evaluated through a 6x4 matrix,
which through a toy car is moving according to the orders that the students
provided on the control board (see Fig. 2).
- The level of attention of the students registered with the MindWave and eaters
as evaluated, is the Sphero sphere (see Fig. 2).</p>
      <sec id="sec-5-1">
        <title>5.1 Logic and Memory Test</title>
        <p>This type of test consists in controlling the 3D printed toy car to advance on the
obstacle track using the control board, and responding at the same time logic and
memory questions, the process is described in Fig. 3.</p>
        <p>The questions of this test are answered through the mobile application, it is given
4 options to the student for each question, so that he selects the opposition he
considers correct (see Fig. 4); To enable the response option, the student has to
continue to be mobilized by the obstacle track.</p>

        <title>5.2 Attention Test</title>
        <p>This second type of test is to measure the student's attention, the sphere (Sphero)
moves at a speed according to the student's attention level that captures the headband
of Mindwave. The steps to follow are (see Fig. 5).</p>
        <p>At the top of the mobile application (see Fig. 6) the student's attention and
meditation values is shown, in the central part a joystick to control the Sphero in case,
a clonomer that will start at the time of receiving signals of the Mindwave. The little
joystick serves to calibrate the Sphero.</p>

      <title>Results</title>
      <p>For this research, was experienced with the logic, memory and attention of 104
students of 5th and 6th primary (10-12 years) in three educational institutions, of
which 35 belong to a school of Misses, 35 to a college of males and the remaining 34
to a mixed school. For reasons of confidentiality, we will call them together School 1,
School 2 and School 3.</p>
      <p>
        In Fig. 7 shows that, the School 1 of Misses and the School 2 of Males have an
increase in logic, memory and attention according to the degree they are studying (5th
and 6th degree of primary), that because children are constantly development of their
brain over the years and technology promotes this [

        ].
      </p>
      <p>Respect to Fig. 8, it shows that in the Mixed School, it has the same trend as in
Fig.7, that the overview of years are higher percentages than their predecessor.</p>
      <p>Finally, the total of students had been made a set of questions linked to interactive
toy, in Fig. 9, shows that 58% seems very interesting, 38% interesting and only 4%
indifferent, the result reflects the interest it has on the game.

      <title>Discussion</title>
      <p>
        The results of this investigation are in a medium-high range, as well as research
[
        <xref ref-type="bibr" rid="ref17">17</xref>
        ], where participants reflect higher attention levels by interacting with a toy or a
digital object. Also regarding research [
        <xref ref-type="bibr" rid="ref18">18</xref>
        ], our averages of attention during the test
are between 60 and 70%, both projects are based on stage games, to maintain the
interest and high attention of the participants. Finally, it is verified that participants
who came to obtain better levels of attention have higher percentage of hits in logic
and memory tests, this is in relation to research [
        <xref ref-type="bibr" rid="ref19">19</xref>
        ], where students have a middle in
meditation and attention, so they get a smaller qualification in the exam.
      </p>
      <p>
        As noted in Fig. 9 our toy showed a high level of acceptance by participants as in
[
        <xref ref-type="bibr" rid="ref20">20</xref>
        ] that proposes a game using Arduino showing high level of enthusiasm in the
participants. Also, in [
        <xref ref-type="bibr" rid="ref21">21</xref>
        ] the results show the highest level of satisfaction in those
participants to make use of Sphero.
      </p>
      <p>
        Finally, [
        <xref ref-type="bibr" rid="ref16">16</xref>
        ] is in accordance with our results shown as it concludes that the
cognitive development of children with technology brings good results. This
conclusion is based on research [
        <xref ref-type="bibr" rid="ref22">22</xref>
        ] where repetitive sections in the participants
entail better results, as they are reflected in our research where the participants of
higher grades had better results compared to others.

      <title>8 Conclusions and future works</title>
      <p>Apply integrated games with technological objects in education, it is of great
benefit for students, as these compared to conventional games, are to be more
entertaining, increase motivation and managing to capture the attention and interest of
the students, so, it is a resource that must be taken advantage, since it contributes to
the development of intellectual skills and capabilities.</p>
      <p>With the Arduino plate, the toy car, the command board, the 6x4 track, Neurosky
MindWave EEG, and Sphero was achieved to develop an interactive toy that allowed
to attract attention and entertain the elementary students and improve their memory,
logical and attention.</p>
      <p>The evaluation of the 104 primary education students allowed to verify, that
students with better levels of attention, logic and memory are the superior years, due
to the development of the brain reached in school ages.</p>
      <p>The integration of the sphere (Sphero) was achieved with the Neurosky MindWave
EEG, so that, when the student reaches the level of concentration required, this is
reflected in the speed of the movement of the sphere, that is to say higher
concentration greater speed and vice versa, lower concentration lower speed.</p>
      <p>The didactic toy has an acceptance of 96% of the 104 students surveyed, in three
different educational schools of primary, showing that students have an entertaining
learning to develop memory, logical and attention.</p>
      <p>With the developed proposal, the schools are expected to adapt new learning
strategies to learn the deficiencies of the students in the different degrees, since it is
necessary for teachers and managers to use new technological tools to complement
the student's methodology.</p>
