Multisensory Analysis of Consumer-Product Interaction During Ceramic Tile Shopping Experiences

[EN] The need to design products that engage several senses has being increasingly recognised by design and marketing professionals. Many works analyse the impact of sensory stimuli on the hedonic, cognitive, and emotional responses of consumers, as well as on their satisfaction and intention to purchase. However, there is much less information about the utilitarian dimension related to a sensory non-reflective analysis of the tangible elements of the experience, the sequential role played by different senses, and their relative importance. This work analyses the sensorial dimension of consumer interactions in shops. Consumers were filmed in two ceramic tile shops and their behaviour was analysed according to a previously validated checklist. Sequence of actions, their frequency of occurrence, and the duration of inspections were recorded, and consumers were classified according to their sensory exploration strategies. Results show that inspection patterns are intentional but shifting throughout the interaction. Considering the whole sequence, vision is the dominant sense followed by touch. However, sensory dominance varies throughout the sequence. The dominance differences appear between all senses and within the senses of vision, touch and audition. Cluster analysis classified consumers into two groups, those who were more interactive and those who were visual and passive evaluators. These results are very important for understanding consumer interaction patterns, which senses are involved (including their importance and hierarchy), and which sensory properties of tiles are evaluated during the shopping experience. Moreover, this information is crucial for setting design guidelines to improve sensory interactions and bridge sensory demands with product features.The Spanish Ministry of Culture and Education funded this research with Grant No. PSE-020400-2007-1.Artacho Ramírez, MÁ.; Alcantara Alcover, E.; Martínez, N.

Design specifications to develop a pilota valenciana protection glove

[EN] This paper covers the first phase of a project aimed at developing a protective glove for pilota valenciana. At present, players do not use specific equipment to protect their hands, and the lack of scientific knowledge for the development of specific materials is notable. Within this context, we present a study based on questionnaires administered to 100 pilota valenciana players (51 playing professionally). The purpose is to establish the design specifications of a future protective glove as well as to determine a standard protection. Some results show that 64% of the players believe their protections to worsen performance and 84% of them spend one hour or more to make them. The need to overcome the disadvantages of the current protections has been proved, and design specifications by players must be kept in mind.[ES] El presente artículo se corresponde con la fase inicial de un proyecto que tiene como objetivo desarrollar un guante de protección para jugar a pilota valenciana. Actualmente, los jugadores no tienen un equipamiento específico de garantía para protegerse las manos y existe una ausencia general de conocimiento científico para desarrollar materiales específicos. En este contexto, se presenta un estudio de encuestas sobre 100 jugadores de pilota valenciana, 51 de ellos profesionales, acerca de las protecciones tradicionales que utilizan. El objetivo es definir las especificaciones de diseño de la futura protección así como definir una protección tipo. Algunos de los resultados más destacables indican que el 84% de los jugadores emplean una hora o más en confeccionarse la protección y que 64% de los jugadores consideran que sus protecciones empeoran el rendimiento. Se ha comprobado que las actuales protecciones resultan ineficaces en términos de rendimiento y confort.Montaner, C.; Llana, S.; Gamez Paya, J.; Alcantara Alcover, E. (2012).

Standardization process for paddle facilities

[EN] During the last years, the number of players of paddle has increased enormously in Spain and it has caused an increase in the number of facilities for this sport. In this sense, the Spanish Paddle Association (FEP) has decided to count with IBV as technical partners to start a standardization process of this kind of facilities and the elements included on them. The IBV will be the only laboratory accredited by the FEP to approve this facilities according the FEP¿s standards.[ES] En los últimos años el aumento de la práctica del pádel en España ha sido enorme y también la cantidad de nuevas pistas instaladas, en muchos casos sin ningún control en aspectos tan importantes como la seguridad de los usuarios. En este sentido, la Federación Española de Pádel ha decidido contar con el Instituto de Biomecánica (IBV) como socio técnico para poner en marcha un proceso de homologación de instalaciones destinadas a la práctica de este deporte, así como de los elementos que las componen. El IBV será el único laboratorio acreditado por dicha federación para llevar a cabo la homologación de pistas.Ávalos Brunetti, H.; Sanchís Almenara, M.; Magraner Llavador, L.; Alcantara Alcover, E.

El césped artificial en instalaciones deportivas municipales. De la licitación al mantenimiento

[ES] Desde los años 60 los campos de hierba artificial han evolucionado notablemente. La mejora en materiales y su montaje ha acercado su rendimiento al de los campos de hierba natural, mejorando aspectos como el mantenimiento y uso intensivo de las instalaciones. Para minorar problemas en la realización de una instalación nueva o la renovación de una existente es clave la ejecución de sus diferentes fases, desde una redacción correcta de los pliegos para la licitación, la ejecución y supervisión de las obras o el momento de la aceptación de la misma. Eso, sin olvidar la necesidad de hacer un mantenimiento que nos permita alargar la vida útil del campo en condiciones óptimas.

Influence of age, gender and obesity on pressure discomfort threshold of the foot: A cross-sectional study

[EN] Background: Foot pain is a highly prevalent health problem for which measures such as a pattern of Pressure Discomfort Threshold of the foot plantar surface can provide valuable information for orthosis design. This study aimed to describe such pattern as a tool for the assessment of painful conditions of the feet and to analyse how it modifies according to age, gender and obesity. Methods: A cross-sectional study was performed with participants allocated in: Group 1 people aged 20 to 35 years, Group 2 aged 50 to 65 years and Group 3 aged over 65. Pressure Discomfort Threshold on twelve points of the foot plantar surface was measured with an adapted manual dynamometer. Inferential analyses of the data were performed using one-way analysis of variance (ANOVA) considering foot areas, age group, gender and obesity. Findings: 36 participants were analysed. The pattern of Pressure Discomfort Threshold for all individuals showed a significantly higher threshold on the heel and external foot (P < 0.001, eta(2) = 0.124) and was statistical significantly influenced by age (P < 0.001, eta(2) = 0.17), especially in participants aged over 65; by gender, with women having higher values (P < 0.001, eta(2) = 0.13), and by obesity (P < 0.001, eta(2) = 0.19). Interpretation: A Pressure Discomfort Threshold pattern exists in the foot plantar surface. The characteristics of the discomfort pattern of the foot and its association with aging, gender and obesity may have considerable implications for orthosis and footwear design.Dueñas, L.; Arnal-Gómez, A.; Aparicio, I.; Balasch-Bernat, M.; López-Bueno, L.; Gonzalez Garcia, JC.; Solves Camallonga, C....

Tatami laboratory for the world karate federation

[EN] The sports flooring is a key element in sports practice, both from the point of view of safety and performance. In sports such as karate, this importance is heightened given the speed of movement that this sport demands and falls suffered by sportsmen during the course of it. In this sense, the World Karate Federation has carried out a study with the Biomechanics Institute of Valencia to work on a tatamiapproval process to ensure appropriate behavior and homogeneous thereof.[ES] El pavimento deportivo es un elemento clave en la práctica deportiva, tanto desde el punto de vista de la seguridad como del rendimiento. En deportes como el karate, esta importancia se acentúa dada la rapidez en los movimientos que exige esta disciplina deportiva y las caídas sufridas por los deportistas durante el desarrollo de la misma. En este sentido, la Federación Mundial de Karate ha llevado a cabo un estudio junto con el Instituto de Biomecánica para trabajar en un proceso de homologación de tatamis que garantice un comportamiento adecuado y homogéneo de los mismos.Gomez Sendra, F.; Sanchís Almenara, M.; Pereira Carrillo, IM.; Alcantara Alcover, E.; Magraner Llavador, L.; Piza Padial, M.; Prat Pastor, JM.

Safety tennis courts ensuring performance of players

[EN] Shoe surface interaction is a key factor in tennis due to this is a very quick play. A poor friction normally will mean slips and lost points, and an excessive friction will probably cause injuries due to high loads in joints like knee and ankle. In this sense, the objective of the project coordinated by ITF and developed in collaboration with IBV, Sheffield University and INCOTEC, is to develop a device to evaluate shoe-surface interaction in tennis courts and to identify the optimum friction of clay surfaces.[ES] El tenis es un deporte que se desarrolla a una velocidad considerable y en el que la interacción entre el calzado y la superficie de juego tiene un papel fundamental. Un agarre insuficiente de la pista implicará, en la mayoría de los casos, la pérdida de un punto por parte del jugador y un agarre desmesurado puede provocar lesiones articulares por cargas excesivas. En este sentido, el proyecto coordinado por la Federación Internacional de Tenis (ITF), en el que colabora el Instituto de Biomecánica (IBV) junto con INCOTEC y la Universidad de Sheffield, tiene por objetivo desarrollar un sistema de medida de la interacción calzado-pavimento, así como los criterios a tener en cuenta para determinar si una pista es apta o no para la práctica del tenis.Sanchís Almenara, M.; Alcantara Alcover, E.; Gimeno Peña, S.; Magraner Llavador, L.; Parrilla Bernabé, E.; Moraga Maestre, R.; Matey González, FJ....
