Item type:Publication, Human–Object Interaction: Development of a Usability Index for Product Design Using a Hierarchical Fuzzy Axiomatic Design(2024) ;Mayra Ivette Peña-Ontiveros ;Balderrama Armendariz, Cesar Omar; ;Maldonado Macías, Aide AracelyCortés Sáenz, David<jats:p>Consumer product usability has been addressed using tools that evaluate objects to improve user interaction. However, such diversity in approach makes it challenging to select a method for the type of product being assessed. This article compiles the concepts used since the origin of usability in product design. It groups them by attributes to formulate a usability index proposal. Due to the nature of the data, fuzzy, hierarchical, and axiomatic tools were applied to a trial group of experts and users. Three questionnaires were designed and administered throughout a five-stage process to collect and select attributes, rank them in importance, assign fuzzy values, obtain their numerical representation of use, and assign a qualitative category. By analyzing a case study, this research demonstrates the value of the index by comparing the use of computer mice. Unlike other approaches to evaluating usability, the proposed index incorporates the hierarchical importance of attributes. It allows for participants to express their opinions, transforming subjective responses into linguistic values represented in triangular areas, resulting in a more accurate representation of reality. Additionally, the complexity of the human–object interaction is treated by an information axiom to compute the usability index on a scale from 0 to 1, which reflects the probability of the product meeting the desired usability attributes.</jats:p>16Scopus© Citations 3 - Some of the metrics are blocked by yourconsent settings

Item type:Publication, A low-cost instrumented vital signs testbed for efficient pet sterilization(2022)Advances in technology have changed the way we live. This change has even reached the pet industry. Humans have realized along time the importance of caring for animals. Within such care, sterilization is a very important point for domestic animals. The governments of different countries have created campaigns for mass sterilization of animals to improve their quality of life. However, in developing countries, there are limited budgets directly affecting the quality of the material and equipment for this purpose. Because of this, in this paper, we show the development of a low-cost sterilization bed that will reduce process time, increasing safety and quality. The prototype encompasses heart rate and oxygenation sensors, allowing the animal's vital symptoms to be always monitored. The experimental bed system has sensors to calculate the weight, temperature, and heart rate of the animal, without the need to move it to different places and to be able to monitor it continuously during surgery. Regarding the methodology, average response times of surgery in small animals (dogs and cats) are analyzed, vital signs measurement parameters are compared, and efficiency and cost are verified compared to conventional beds. It is concluded that the proposed measuring bed is an effective and economical alternative in surgical interventions in small animals. Key Words: Pets, Sterilization, Testbed, Vital signs.25
