An eye-tracking project in industrial design education: A case study for engaging in the research process

[EN] The practice of design is constantly evolving; new technologies have become a support for the implementation of disruptive proposals in diverse disciplines, including design products. A Paradigm shift are present in the design and engineering education related with support technologies and developing new products. The objective of this work is to present the novel process of a design project that incorporates a creative and objective process for designing and validating products in order to attract, engage and retain talent in design and engineering courses for research and technology implementation. The challenge was a project for create an novelty industrial tool board with a minimum number of tools validated by Eye-tracking (ET) technology. The ET technology is based on the study of eye movement, which provides an objective indicator of where a person's overt, and typically centered, attention is focused. Twenty-eight students from the third year of Industrial Design Bachelor's program were involved in this academic course and used a product design methodology to implement the technology and dynamics of the ET. The results of this education project revealed a novel dynamic in design education. The results reveled an improved interest in research and technology implementation. Students perceived the relevance of ET technology in a fundamental phase of product design. In addition, the students shared their enjoyment and interest in reusing this technology in similar processes. The students' perception of factors, such as utility, novelty and relevance of this technology, in their design processes was positive. Finally, the novel process became familiar to the students, even if it was their first-time using ET technology. This work reveals how technology becomes a fundamental part of the process and how to guide students to integrate rigid and meticulous processes in design products without neglecting the creative process.The authors would also like to acknowledge the financial support provided by the Novas grant (Laboratorio de disetio, exploracion y validacion de productos y cspacios), PEP No. PHHT002 18ZZ00041, as well as the support of the Writing Lab and TecLabs at Tecnologico de Monterrey, Mexico, throughout the production of this work.Márquez Cañizares, JC.; Rojas, J.; Higuera-Trujillo, JL.; Muniz, G.

Product Validation in Creative Processes: A Gender Perspective in Industrial Design Projects

[EN] Design education and practice are continuously evolving. Educational institutions must include intellectual complexities and new curriculum to support good design education. The design education future emerges multidisciplinary knowledge, teaching innovation and employment necessities. This paper describes a methodology centered in product validation with industrial design students. Focusing on discovering the student experience during the project execution, in addition to observing closely the female design student's perception on the methodology and process developed. The academic project was the design of a novel tool board. The students developed the proposed project in a period of eight weeks. Sixteen students participated as a sample of this research. The methodology consisted of eight phases that spanned from project brief to project conclusion, introducing two phases focused on validation exercises for the elements created to reach the solution of the tool board. During the end of the two evaluation phases, two surveys were applied asking for information on his previous experience during his design education and three elements that assessment the design methodology implementation: utility, novelty, and relevance. Using multiple choice and Likert scale answers the students answered the surveys. The survey's findings revealed relevant information on the project implementation focused on evaluation phases during the product design. The results revealed how students reflected on their previous experience developing projects, and how the design tool board integrate important phases like validation. Also, the students evaluated with a positive value the utility, novelty, and relevance of the developed project. However, the most important finding was the female perception comparing male students. The female assessment of novelty and relevance increased during project implementation, highlighting novelty as a perceived element to a greater range than men. This research results allowed us to discover more information about female students experience with creative and validation processes.The authors would also like to acknowledge the financial support provided by the NOVUS grant ID: N20-158-41 (Validación científica como herramienta educativa en proyectos de carácter creativo), as well as the support of the Writing Lab and TecLabs at Tecnologico de Monterrey, Mexico, throughout the production of this work.Rojas, J.; Higuera-Trujillo, JL.; Muniz, G.; Marín-Morales, J.
