The results obtained from the surveys, considering the usability of the chatbot and the accuracy of the responses, show that the level of satisfaction of using the chatbots is high, therefore, it is recommended to use this type of systems for the attention of users.</span></span><br /><br /><b style="color: #323232; font-family: Arial, Tahoma, Helvetica, FreeSans, sans-serif; font-size: 13px;">Keywords:</b><span style="color: #323232; font-family: Arial, Tahoma, Helvetica, FreeSans, sans-serif;"><span style="font-size: 13px;"> chatbot, higher education, usability, ICT</span></span><br /><br /><b style="color: #323232; font-family: Arial, Tahoma, Helvetica, FreeSans, sans-serif; font-size: 13px;">Link:</b><span style="color: #323232; font-family: Arial, Tahoma, Helvetica, FreeSans, sans-serif; font-size: 13px;"> </span><span style="color: #323232; font-family: Arial, Tahoma, Helvetica, FreeSans, sans-serif;"><span style="font-size: 13px;"><a href="https://ieeexplore.ieee.org/abstract/document/9141108">https://ieeexplore.ieee.org/abstract/document/9141108</a></span></span></div></div>Jorge Corderohttp://www.blogger.com/profile/05051222944654787679noreply@blogger.com0tag:blogger.com,1999:blog-5485113492557482320.post-67732626289527022962020-02-10T16:29:00.001-05:002022-11-07T16:34:34.419-05:00Recognition of the driving style in vehicle drivers<p><span style="color: #323232; font-family: Arial, Tahoma, Helvetica, FreeSans, sans-serif; font-size: 13px;">Authors: </span><span style="color: #323232; font-family: Arial, Tahoma, Helvetica, FreeSans, sans-serif;"><span style="font-size: 13px;">J Cordero, J Aguilar, K Aguilar, D Chávez, E Puerto</span></span></p><div style="background-color: white; color: #323232; font-family: Arial, Tahoma, Helvetica, FreeSans, sans-serif; font-size: 13px;"><b>Abstract:</b></div><div class="post-body entry-content" id="post-body-2369135227340120173" itemprop="description articleBody" style="background-color: white; line-height: 1.4; position: relative; width: 566px;"><div class="post-body entry-content" id="post-body-1949088186443264008" itemprop="description articleBody" style="line-height: 1.4; position: relative; width: 566px;"><span style="color: #222222; font-family: Arial, sans-serif; font-size: 13px;">This paper presents three different approaches to recognize driving style based on a hierarchical-model. Specifically, it proposes a hierarchical model for the recognition of the driving style for advanced driver-assistance systems (ADAS) for vehicles. This hierarchical model for the recognition of the style of the car driving considers three aspects: the driver emotions, the driver state, and finally, the driving style itself. In this way, the proposed hierarchical pattern is composed of three levels of descriptors/features, one to recognize the emotional states, another to recognize the driver state, and the last one to recognize the driving style. Each level has a set of descriptors, which can be sensed in a real context. Finally, the paper presents three driving style recognition algorithms based on different paradigms. One is based on fuzzy logic, another is based on chronicles (a temporal logic paradigm), and the last is based on an algorithm that uses the idea of the recognition process of the neocortex, called Ar2p (Algoritmo Recursivo de Reconocimiento de Patrones, for its acronym in Spanish). In the paper, these approaches are compared using real datasets, using different metrics of interest in the context of the Internet of the Things, in order to determine their capabilities of reasoning, adaptation, and the communication of information. In general, the initial results are encouraging, specifically in the cases of chronicles and Ar2p, which give the best results.</span><span style="color: #323232; font-family: Arial, Tahoma, Helvetica, FreeSans, sans-serif;"><span style="font-size: 13px;">.</span></span><br /><br /><b style="color: #323232; font-family: Arial, Tahoma, Helvetica, FreeSans, sans-serif; font-size: 13px;">Keywords:</b><span style="color: #323232; font-family: Arial, Tahoma, Helvetica, FreeSans, sans-serif;"><span style="font-size: 13px;"> pattern recognition, driving style, intelligent techniques, advanced driver-assistance systems</span></span><br /><br /><b style="color: #323232; font-family: Arial, Tahoma, Helvetica, FreeSans, sans-serif; font-size: 13px;">Link: </b><span style="color: #323232; font-family: Arial, Tahoma, Helvetica, FreeSans, sans-serif;"><span style="font-size: 13px;"><a href="https://www.mdpi.com/1424-8220/20/9/2597/pdf?version=1588415475">https://www.mdpi.com/1424-8220/20/9/2597/pdf?version=1588415475</a></span></span></div></div>Jorge Corderohttp://www.blogger.com/profile/05051222944654787679noreply@blogger.com0tag:blogger.com,1999:blog-5485113492557482320.post-11362969623533237032020-02-04T16:35:00.001-05:002022-11-07T16:37:40.522-05:00Advanced Driver Assistance System for the drowsiness detection using facial landmarks<p><span style="color: #323232; font-family: Arial, Tahoma, Helvetica, FreeSans, sans-serif; font-size: 13px;">Authors: </span><span style="color: #323232; font-family: Arial, Tahoma, Helvetica, FreeSans, sans-serif;"><span style="font-size: 13px;">LDS Cueva, J Cordero</span></span></p><div style="background-color: white; color: #323232; font-family: Arial, Tahoma, Helvetica, FreeSans, sans-serif; font-size: 13px;"><b>Abstract:</b></div><div class="post-body entry-content" id="post-body-2369135227340120173" itemprop="description articleBody" style="background-color: white; line-height: 1.4; position: relative; width: 566px;"><div class="post-body entry-content" id="post-body-1949088186443264008" itemprop="description articleBody" style="line-height: 1.4; position: relative; width: 566px;"><span style="color: #323232; font-family: Arial, Tahoma, Helvetica, FreeSans, sans-serif;"><span style="font-size: 13px;">This paper presents the development of a solution to detect a driver's drowsiness in real time and issue alerts to avoid possible traffic accidents.

In addition to cars, the application count pedestrians. Frameworks used are: SSD Mobilenet retrained, SSD Mobilenet pre-trained, and GoogLeNet pre-trained. The evaluation data set has a total duration of 60 minutes and comes from three different cameras. Images from the real deployment videos are included when training to enrich the detectable cases. Traditional detection models applied to vehicle counting systems usually provide high values for cars seen from the front. However, when the observer or camera is on the side, some models have lower detection and classification values. A new data set with fewer classes reach similar performance values as trained methods with default data sets. Results show that for the class cars, recall and precision values are 0.97 and 0.90 respectively in the best case, making use of a trained model by default, while for the class people the use of a re-trained model provides better results with precision and recall values of 1 and 0.82.</div><div class="post-body entry-content" id="post-body-1949088186443264008" itemprop="description articleBody" style="line-height: 1.4; position: relative; width: 566px;"><br /></div></div><div class="post-body entry-content" id="post-body-1949088186443264008" itemprop="description articleBody" style="line-height: 1.4; position: relative; width: 566px;"><b style="color: #323232; font-family: arial, tahoma, helvetica, freesans, sans-serif; font-size: 13px;">Keywords:</b><span face="arial, tahoma, helvetica, freesans, sans-serif" style="color: #323232; font-size: 13px;"> </span>Convolutional Neural Networks, learning transfer, automatic counter, classification, tracking, Single Shot Detector, Mobilenet<br /><br /></div></div></div><p><b style="background-color: white; color: #323232; font-family: arial, tahoma, helvetica, freesans, sans-serif; font-size: 13px;">Link:</b><span face="arial, tahoma, helvetica, freesans, sans-serif" style="background-color: white; color: #323232; font-size: 13px;"> <a href="https://ieeexplore.ieee.org/abstract/document/8781795">https://ieeexplore.ieee.org/abstract/document/8781795</a></span></p>Jorge Corderohttp://www.blogger.com/profile/05051222944654787679noreply@blogger.com0tag:blogger.com,1999:blog-5485113492557482320.post-41106965013498977052019-08-06T15:47:00.000-05:002022-11-07T15:51:37.349-05:00Approaches to identify student learning styles through emotions in a classroom<p><span style="color: #323232;"><span style="font-size: 13px;">Sistema de Gestión de las emociones en un salón de </span></span><span style="color: #323232; font-size: 13px;">clases inteligente basado en Modelos de confianza y </span><span style="color: #323232; font-size: 13px;">reputación</span></p><p><span face="Arial, Tahoma, Helvetica, FreeSans, sans-serif" style="color: #323232; font-size: 13px;">Authors: </span><span face="Arial, Tahoma, Helvetica, FreeSans, sans-serif" style="color: #323232; font-size: 26px;"><span style="font-size: 13px;">J Cordero, J Aguilar, K Aguilar, M Martinez</span></span></p><div class="post-body entry-content" id="post-body-3957973509620868694" itemprop="description articleBody" style="background-color: white; line-height: 1.4; position: relative; width: 566px;"><div style="color: #323232; font-family: Arial, Tahoma, Helvetica, FreeSans, sans-serif; font-size: 13px;"><span face="arial, tahoma, helvetica, freesans, sans-serif"><br /></span></div><div class="post-body entry-content" id="post-body-2369135227340120173" itemprop="description articleBody" style="line-height: 1.4; position: relative; width: 566px;"><div class="post-body entry-content" id="post-body-1949088186443264008" itemprop="description articleBody" style="line-height: 1.4; position: relative; width: 566px;"><b style="color: #323232; font-family: arial, tahoma, helvetica, freesans, sans-serif; font-size: 13px;">Abstract:</b><br /><div class="post-body entry-content" id="post-body-1949088186443264008" itemprop="description articleBody" style="line-height: 1.4; position: relative; width: 566px;">In this article, we propose a model of trust and reputation, for the
management of emotions in a Smart Classroom (SaCI). In general, a SaCI can
model its different hardware and software components as agents. On the other
hand, in intelligent environments modeled with agents, it is necessary to define
the interaction mechanisms used in conversations between agents. In addition, the
conversations should be enriched with models of trust and reputation of the agents involved in them, so that each agent can decide what information coming from
the different agents, to consider when executing their decision-making processes.
In particular, this paper defines models of trust and reputation for the SaCI
agents. These models are used in a conversation that performs the management
of emotions in SaCI, which allows to define the emotion that prevails at a given
moment in it, which we call social emotion. The conversation is tested in several
cases of study, in order to validate its ability to establish the social emotion of SaCI.
The experimental results with the emotion management system based on models of
trust and reputation, demonstrate that it is able to determine the social emotion in
SaCI regardless of the characteristics of its context and learning from the behavior
of agents, which gives it great robustness.</div><div class="post-body entry-content" id="post-body-1949088186443264008" itemprop="description articleBody" style="line-height: 1.4; position: relative; width: 566px;"><br /></div></div><div class="post-body entry-content" id="post-body-1949088186443264008" itemprop="description articleBody" style="line-height: 1.4; position: relative; width: 566px;"><b style="color: #323232; font-family: arial, tahoma, helvetica, freesans, sans-serif; font-size: 13px;">Keywords:</b><span face="arial, tahoma, helvetica, freesans, sans-serif" style="color: #323232; font-size: 13px;"> trust model, reputation model, emotion management, social emotion,

style of students in a classroom, which is composed of two levels, one to recognize
the emotional state, and another to identify the learning style. Each level is defined
by different types of descriptors, which are perceived from a multimodal approach.
In addition, using the hierarchical pattern, two approaches are analyzed to model
the learning style, which can be visual, auditory, reading/writing, kinesthetic.
One of the approaches is based on fuzzy logic, and another based on chronicles,
which exploit the idea of recursion and learning in the recognition process.
Finally, considering the dynamic environment of a classroom, the approaches are
compared, in terms of their abilities to learn and to determine the learning styles; and to communicate that information clearly in a smart classroom, based on the
recognized emotions.</div></div><div class="post-body entry-content" id="post-body-1949088186443264008" itemprop="description articleBody" style="line-height: 1.4; position: relative; width: 566px;"><span face="arial, tahoma, helvetica, freesans, sans-serif" style="color: #323232;"><span style="font-size: 13px;"><div class="post-body entry-content" id="post-body-1949088186443264008" itemprop="description articleBody" style="line-height: 1.4; position: relative; width: 566px;"><br /></div></span></span><b style="color: #323232; font-family: arial, tahoma, helvetica, freesans, sans-serif; font-size: 13px;">Keywords:</b><span face="arial, tahoma, helvetica, freesans, sans-serif" style="color: #323232; font-size: 13px;"> Hierarchical patterns, learning style, emotion recognition, fuzzy logic,

It uses the OpenFace algorithm based on neural networks, taking input from two-dimensional images of the student from time to time during the participation on the exam. We present a system for face recognition using an image database of faces in classroom setting to demonstrate the improvement using this OpenFace algorithm for the preprocessing approach. The preliminary results indicate a high accuracy in the recognition of students, in terms of brightness, size and quality of the image of the face.</span></span></div><div class="post-body entry-content" id="post-body-1949088186443264008" itemprop="description articleBody" style="line-height: 1.4; position: relative; width: 566px;"><span face="arial, tahoma, helvetica, freesans, sans-serif" style="color: #323232;"><span style="font-size: 13px;"><div class="post-body entry-content" id="post-body-1949088186443264008" itemprop="description articleBody" style="line-height: 1.4; position: relative; width: 566px;"><br /></div></span></span><b style="color: #323232; font-family: arial, tahoma, helvetica, freesans, sans-serif; font-size: 13px;">Keywords:</b><span face="arial, tahoma, helvetica, freesans, sans-serif" style="color: #323232; font-size: 13px;"> </span><span face="arial, tahoma, helvetica, freesans, sans-serif" style="color: #323232;"><span style="font-size: 13px;">Computational intelligence, Computer vision, Face authentication, Neural networks, OpenFace algorithm</span></span><br /><br /><b style="color: #323232; font-family: arial, tahoma, helvetica, freesans, sans-serif; font-size: 13px;">Link:</b><span face="arial, tahoma, helvetica, freesans, sans-serif" style="color: #323232; font-size: 13px;"> </span><span face="arial, tahoma, helvetica, freesans, sans-serif" style="color: #2988d4;"><span style="font-size: 13px;"><a href="https://link.springer.com/chapter/10.1007/978-3-030-05532-5_37">https://link.springer.com/chapter/10.1007/978-3-030-05532-5_37</a> </span></span></div></div></div>Jorge Corderohttp://www.blogger.com/profile/05051222944654787679noreply@blogger.com0tag:blogger.com,1999:blog-5485113492557482320.post-39579735096208686942017-10-27T15:00:00.000-05:002017-10-30T08:19:55.403-05:00Specification of the Autonomic Cycles of Learning Analytic Tasks for a Smart Classroom<h3 class="post-title entry-title" itemprop="name" style="background-color: white; color: #d52a33; font-family: arial, tahoma, helvetica, freesans, sans-serif; font-size: 26px; font-stretch: normal; line-height: normal; margin: 0px; position: relative;">

<span style="color: #323232; font-family: "arial" , "tahoma" , "helvetica" , "freesans" , sans-serif;"><span style="font-size: 13px;">In this article, we propose the concept of ‘‘Autonomic Cycle Of Learning Analysis Tasks’’ (ACOLAT), which defines a set of tasks of learning analysis, whose objective is to improve the learning process. The data analysis has become a fundamental area for the knowledge discovery from data extracted from different sources. In the autonomic cycle, each learning analysis task interacts with each other and has different roles: Some of them must observe the learning process, others must analyze and interpret what happens in it, and finally, others make decisions in order to improve the learning process. In this article, we study the application of the autonomic cycle in a smart classroom, which is composed of a set of intelligent components of hardware (e.g., smart board) and software (e.g., virtual learning environments), which must exploit the knowledge generated by the ACOLAT to improve the learning process in the smart classroom. Moreover, we present the set of ACOLATs present in a smart classroom and the implementation of some of them.</span></span><br />

<span style="color: #323232; font-family: "arial" , "tahoma" , "helvetica" , "freesans" , sans-serif;"><span style="font-size: 13px;">Learning Analytic is a useful tool in the context of the learning process, in order to improve the educational environment. In previous works, we have proposed autonomic cycles of learning Analytic tasks, in order to improve the learning process in smart classrooms. One aspect to be considered by the autonomic cycles is their adaptability to the formation of competences, assuming that a student has competences that must be strengthened during the learning process. In this paper, we propose the utilization of competences to guide the adaptation process of a learning environment. Particularly, we propose the extensions of the autonomic cycles for smart classrooms, using the idea of competences. In this case, we define the competences as a service, to help the autonomic cycles in their processes of adaptation.</span></span><br />

Additionally, we analyze three techniques to recognize the style of driving, using our hierarchical pattern, one based on fuzzy logic, another based on chronicles (a temporal logic paradigm), and another based on an algorithm that models the functioning of the human neocortex, exploiting the idea of recursivity and learning in the recognition process.

On the other hand, the learning analytics tasks are a set of tools that can be used to collect and analyze the data accumulated in a smart classroom. In this paper, we propose the definition of the learning analytics tasks as services, which can be invoked by the components of a smart classroom. We describe how to combine the cloud and multi-agent paradigms in a smart classroom, in order to provide academic services to the intelligent and non-intelligent agents in the smart classroom, to adapt and respond to the teaching and learning requirements of students. Additionally, we define a set of learning analytics tasks as services, which defines a knowledge feedback loop for the smart classroom, in order to improve the learning process in it, and we explain how they can be invoked and consumed by the agents in a smart classroom.</span></span></span><br style="background-color: white; color: #323232; font-family: Arial, Tahoma, Helvetica, FreeSans, sans-serif; font-size: 13px;" /><br style="background-color: white; color: #323232; font-family: Arial, Tahoma, Helvetica, FreeSans, sans-serif; font-size: 13px;" /><b style="background-color: white; color: #323232; font-family: Arial, Tahoma, Helvetica, FreeSans, sans-serif; font-size: 13px;">Keywords:</b><span style="background-color: white; color: #323232; font-family: Arial, Tahoma, Helvetica, FreeSans, sans-serif; font-size: 13px;"> </span><span style="color: #323232; font-family: Arial, Tahoma, Helvetica, FreeSans, sans-serif;"><span style="font-size: 13px;">Learning analytics as service, Smart classroom, Cloud computing, Ambient intelligences</span></span><br style="background-color: white; color: #323232; font-family: Arial, Tahoma, Helvetica, FreeSans, sans-serif; font-size: 13px;" /><br style="background-color: white; color: #323232; font-family: Arial, Tahoma, Helvetica, FreeSans, sans-serif; font-size: 13px;" /><b style="background-color: white; color: #323232; font-family: Arial, Tahoma, Helvetica, FreeSans, sans-serif; font-size: 13px;">Link:</b><span style="background-color: white; color: #323232; font-family: Arial, Tahoma, Helvetica, FreeSans, sans-serif; font-size: 13px;"> </span><a href="http://link.springer.com/chapter/10.1007/978-3-319-48024-4_13" style="background-color: white; color: #17507c; font-family: Arial, Tahoma, Helvetica, FreeSans, sans-serif; font-size: 13px; text-decoration: none;">http://link.springer.com/article/10.1007%2Fs10209-017-0525-0</a><br />

<b><br /></b>
<b>Abstract:</b><br />
In this paper, we propose a recognition model of emotional state using multi-modal perception, a temporal logic paradigm (in particular, we use chronicles), and dynamical patterns. In this way, our recognition approach is based on chronicles to model the patterns, a definition of the emotions as dynamic patterns, and the idea that they are perceived in a multi-modal way (sound, vision, etc.). In this paper, we present these elements of our approach, and give one example of an application for the recognition of the emotions of the driver of a vehicle.<br />

<b>Abstract</b>. In this paper, we propose the utilization of the “Learning Analytics” paradigm in a Smart Classroom, a classroom that integrates artificial intelligence technology on the educational process. Learning Analytics can extract knowledge from the Smart Classroom platform, to better understand students and his/her learning processes. In this way, a Smart Classroom can understand and optimize<br />
the learning process and the teaching environments proposed. The smart classroom can adapt its components to improve students’ performance, among other aspects. Particularly, this paper proposes a framework about how the Learning Analytics paradigm can be used in a Smart Classroom, in order to provide knowledge about the activities taking place within it. The framework is defined like a closed cycle of Learning Analytics tasks, which generate metrics used like feedback to optimize the pedagogical model proposed by the smart Classroom. The metrics evaluate the learning process and pedagogical practice provided by the smart Classroom. So, our main contribution is about how the Learning Analytics paradigm can be used in a Smart Classroom in order to improve the students’<br />
performance.<br />

<b>Autores</b>—Jorge Cordero, Jose Aguilar<br />
<br />
<b>Resumen</b>—En este trabajo se presenta un modelo de reconocimiento multimodal de emociones en tiempo real, para un salón de clases inteligente, basado en crónicas. En nuestro modelo se analizan las emociones a reconocer que están relacionadas con el proceso de aprendizaje, como son: felicidad, tristeza, ira, miedo, y sorpresa. El reconocimiento es multimodal por considerarse diferentes tipos de eventos y formas sensoriales en el proceso de reconocimiento: facial, acústico, lenguaje corporal, y otras variables propias del salón de clases inteligente, como la temperatura, el ruido la luminosidad, entre otros. Este enfoque multimodal permite modelar más precisamente las emociones del usuario, respecto a sistemas de reconocimiento de emociones unimodales.<br />

<br />
<b>Abstract</b><br />
For the development of distributed applications, it is required to define a formalization of the process of implementation. Particularly, we are interested in one type of Ambient Intelligence (AmI), the Smart Classroom. In this paper we propose the implementation of a Smart Classroom, called SaCI, using the concept of communities of agents. With this concept, we carry out the definition and implementation of sets of agents according to their roles, functionalities, characteristics, among others, in SaCI. Each community can be designed and implemented independently and later be integrated in SaCI. In this paper we present this approach and its implementation in SaCI.<br />

<br />
<b>Abstract</b>:<br />
This work aims to implement business intelligence strategies in an educational institution based on the distance education, particularly in the online tutoring process. In this paper we propose to use the business intelligence paradigm to analyze the online tutoring process, based on the data collected on the interactions of students and teachers in a virtual learning environment, and the results recorded in the institutional academic system of evaluations. This analysis should answer the following questions: 1) Can we define a model of online tutoring that can adapt to each student profile? 2) Can we predict the success of an online tutoring process for a course and a student given? To this purpose, this paper presents three aspects: characterize and determine the key elements in an online tutoring process, build a descriptive model of the online tutoring process, and build a predictive model of the success of the online tutoring process. The models to be defined will be based on data mining techniques, and will be obtained from the current data stored in transactional databases of the University. This data is preprocessed with ETL techniques to build a multidimensional model, and the key elements are obtained through operations OLAP.<br />

<b>Abstract </b>- The smart environments have been used in different domains: home, educational and health centers, etc. Particularly, a smart environment in education must integrate different aspects linked to virtual and presencial education, the profile of the students, to the pedagogical paradigm used, etc., in real time. In this paper we characterize a smart classroom considering these aspects, using the multiagent systems paradigm. Particularly, we define the different components of a smart classroom with their properties. Based on that, we describe these components like agents using MASINA, a methodology to specify multiagent systems. We define two frameworks of agents which describe the different types of components in a smart classroom (of software and of hardware), and give examples of applications of these two frameworks in a device and a software of a smart classroom. Finally, we show an example of conversation in a smart classroom based on our multiagents approach, specifically in a work session.<br />

<br />
Resumen—En la literatura se han venido especificando ambientes inteligentes para diferentes ámbitos basados en el paradigma de sistemas multiagentes, como por ejemplo para salones<br />
inteligentes. Por otro lado, los componentes de un salón inteligente necesitan permanentemente comunicarse, interactuar, entre otras cosas, ya que muchas de las tareas deben realizarse colaborativamente. De esta manera, los procesos de coordinación son vitales en estos entornos. En este artículo analizamos el problema de coordinación en un salón inteligente modelado usando agentes, en particular, si es posible formalizarlos matemáticamente; además, presentamos varios casos de estudio. Su formalización matemática es fundamental para poder definir modelos de aprendizaje colectivo en el salón inteligente.<br />

</span><br />
En Excel cuando hacemos usos de fórmulas y funciones es seguro que hagamos referencias a celdas.<br />
Las referencias son enlaces a un lugar, es decir, cuando en una formula escribimos =SUMA(A1;B1) nos estamos refiriendo a que sume el contenido de A1 y el contenido de B1.<br />
<span style="font-weight:bold;">Referencia Relativa:</span><br />
Las referencias de filas y columnas cambian si se copia la formula en otra celda.<br />
<br />
Por ejemplo:<br />
Si copiamos la celda A7 en B8, como la copiamos una columna hacia la derecha y en una fila hacia abajo, la fórmula cambiará por: =B7+2.<br />
<br />
Lo que variará es la referencia a la celda A6, al copiarla una columna hacia la derecha se incrementará el nombre de la columna en uno, es decir, en vez de A pondrá B<br />
y al copiarla una fila hacia abajo en vez de fila 6 pondrá 7, resultado =B7+2.<br />
<span style="font-weight:bold;"><br />
Referencia Absoluta:</span><br />
Las referencias de filas y columnas no cambian si se copia la formula a otra celda, las referencias a las celdas de la formula son fijas.<br />
<br />
Por ejemplo:<br />
<br />
Si copiamos la celda A7 en B8 , aunque la copiemos una columna hacia la derecha y en una fila hacia abajo, como delante de la columna y delante de la fila encuentra en signo $ no variará la fórmula en B8<br />
<br />
El resultado es igual, porque no he variado la referencia.<br />
<br />
Para hacer una referencia absoluta se utiliza el signo de dólar $ antes de la columna y de la fila así: =$A$1+2<br />
