{"title":"An implicit research methodology to evaluate advertising effectiveness in Esports streaming based on viewers’ gaze, cognitive and emotional responses.","authors":"Frano Giakoni, M. López, F. Segado, Aarón Manzanares, Javier Mínguez","doi":"10.6018/sportk.485921","DOIUrl":"https://doi.org/10.6018/sportk.485921","url":null,"abstract":"It is difficult to assess the real effectiveness of the sponsorship of esports for a brand. An initial approach would be to calculate the visibility of the brands’ ads during a broadcast, which is usually characterized in terms of exposition time. Classically, this time was computed manually by visual inspection, but computer vision algorithms have recently automated this process, providing some sort of cost effectiveness parameter. This study goes a step further by proposing a new and complementary research methodology to assess the effectiveness of ads in esports, based on implicit research techniques such as electroencephalogram, galvanic skin response, eye-tracking, and analysis of the gaze behavior of the viewers, along with their emotional and cognitive states. Although there is no scarcity of studies on market investigation and advertising employing these research methodologies, these have not been applied to esports research yet. This study reports the implementation of this methodology in a case study with 48 participants during a given esports match. It is also demonstrated how these new metrics, which capture the non-conscious states of viewers, can be used to assess the performance of ads (in this case, brand logos). Additionally, it is shown how ad exposition time (widely accepted metric to assess ad effectiveness) presents an error of 60.18% with respect to real visualization, and how the methodology presented herein can be used to find the best placements for ad/brand exposure during esports broadcast.\u0000 Es difícil evaluar la eficacia real del patrocinio de los esports para una marca. Una primera aproximación sería calcular la visibilidad de los anuncios de las marcas durante una retransmisión, que se suele caracterizar en términos de tiempo de exposición. Clásicamente, este tiempo se calculaba manualmente mediante inspección visual, pero recientemente los algoritmos de visión por ordenador han automatizado este proceso, proporcionando algún tipo de parámetro de rentabilidad. Este estudio da un paso más al proponer una metodología de investigación nueva y complementaria para evaluar la eficacia de los anuncios en los deportes electrónicos, basada en técnicas de investigación implícitas como el electroencefalograma, la respuesta galvánica de la piel, el seguimiento ocular y el análisis del comportamiento de la mirada de los espectadores, junto con sus estados emocionales y cognitivos. Aunque no escasean los estudios sobre investigación de mercado y publicidad que emplean estas metodologías de investigación, aún no se han aplicado a la investigación de los deportes electrónicos. Este estudio informa de la aplicación de esta metodología en un estudio de caso con 48 participantes durante un partido de esports. También se demuestra cómo estas nuevas métricas, que captan los estados no conscientes de los espectadores, pueden utilizarse para evaluar el rendimiento de los anuncios (en este caso, los logotipos de las marcas).

This analysis was done according to the Theory of Planned Behavior. A survey was conducted on 100 older adults (more than 65 years old) of Central Taiwan. After eliminating the invalid questionnaires, 87 questionnaires were taken back successfully (valid response rate = 87%). Questionnaire data were analyzed by descriptive analysis, confirmatory factor analysis, and structural equation modeling. It was found that the ability to maintain exercise was the most important factor for engaging in health promotion activities. The participation in health exercise courses in a community care center can help older adults to maintain good physical health and can increase social interaction and participation in the community. Therefore, the community health exercise courses are an effective strategy to maintain the regular exercise behavior of older adults in Taiwan.\u0000 El propósito de este estudio fue analizar la conducta de ejercicio y de promoción de la salud en adultos mayores taiwaneses que participaban regularmente en cursos de ejercicio en un centro comunitario de cuidado de ancianos. Este análisis se hizo según la Teoría del Comportamiento Planificado. Se realizó una encuesta a 100 adultos mayores (más de 65 años) de Taiwán central. Después de eliminar los cuestionarios no válidos, 87 cuestionarios se recuperaron con éxito (tasa de respuesta válida = 87%). Los datos del cuestionario se analizaron mediante análisis descriptivo, análisis factorial confirmatorio y modelos de ecuaciones estructurales. Se encontró que la capacidad para mantener el ejercicio fue el factor más importante para participar en actividades de promoción de la salud. La participación en cursos de ejercicios para la salud en un centro de atención comunitario puede ayudar a los adultos mayores a mantener una buena salud física y puede aumentar su interacción social y su participación en la comunidad. Por lo tanto, los cursos comunitarios de ejercicios para la salud son una estrategia eficaz para mantener el comportamiento de ejercicio regular de los adultos mayores en Taiwán.","PeriodicalId":44430,"journal":{"name":"Sport TK-Revista Euroamericana de Ciencias del Deporte","volume":null,"pages":null},"PeriodicalIF":0.6,"publicationDate":"2022-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76343505","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The effective return rate is up to 95.8%. Followed by data collection, statistical analysis was done using various statistical tests which include, descriptive statistics, independent sample t test, single factor variance analysis and snow-fee method post-comparison, Pearson product difference correlation, multiple stepwise regression analysis and logistic regression. Conclusion: The overall consumption motivation of sports lottery consumers present a medium-level cognition situation. The sports spectators scale present a medium-to-low level situation, and the overall sports participation behavior-goal identity present a medium-to-high level cognition situation. Gender has a significant role with respect to entertainment factors and sports spectators in the consumption motivation factor dimension. Age has a significant role with respect  to the public welfare factor in the consumption motivation factor dimension; education degree is in the consumption motivation factor dimension of economic factor, public welfare factor and sports spectators and sports participation behaviors-goal identification were found to be significantly different. Marriage had a significant difference in consumption motivation factor in terms of entertainment factor, public welfare factor and sports spectators and sports participation behaviors-goal identification; occupation is in consumption motivation factors economic factor, public welfare factors have reached a significant difference; monthly income has a significant difference in consumption motivation and sports spectators. Significant correlation was found between consumption motivation and sports appreciation.

It was carried out by simple random sampling, with a sample of 16 athletes among 16-19 years. They were evaluated by means of an evaluation scale with indicators in the race phases: support, impulse and recovery, qualifying the athletes by means of a Likert scale when completing the 1000 m test. The Mann-Whitney test was applied for independent samples in the statistical software SPSS, comparing the pretest with the post test.
