Examining the sense of agency in human-computer interaction

Humans are agents, we feel that we control the course of events on our everyday life. This refers to the Sense of Agency (SoA). This experience is not only crucial in our daily life, but also in our interaction with technology. When we manipulate a user interface (e.g., computer, smartphone, etc.), we expect that the system responds to our input commands with feedback, as we desire to feel that we are in charge of the interaction. If this interplay elicits a SoA, then the user will perceive an instinctive feeling of “I am controlling this”. Although research in Human-Computer Interaction (HCI) pursuits the design of intuitive and responsive systems, most of the current studies have been focussed mainly on interaction techniques (e.g., software-hardware) and User Experience (UX) (e.g., comfort, usability, etc.), and very little has been investigated in terms of the SoA i.e., the conscious experience of being in control regarding the interaction. In this thesis, we present an experimental exploration of the role of the SoA in interaction paradigms typical of HCI. After two chapters of introduction and related work, we describe a series of studies that explore agency implication in interaction with systems through human senses such as vision, audio, touch and smell. Chapter 3 explores the SoA in mid-air haptic interaction through touchless actions. Then, Chapter 4 examines agency modulation through smell and its application for olfactory interfaces. Chapter 5 describes two novel timing techniques based on auditory and haptic cues that provide alternative timing methods to the traditional Libet clock. Finally, we conclude with a discussion chapter that highlights the importance of our SoA during interactions with technology as well as the implications of the results found, in the design of user interfaces

Uso de herramientas de integración continua para reducir el tiempo de despliegue de procesos de Big Data en una entidad financiera

Describe el uso de herramientas de integración continua en los despliegues de procesos de Big Data en una entidad financiera bajo el enfoque de la metodología Kanban. Debido a que la entidad financiera tiene una alta demanda de pases a producción se requiere que el flujo de despliegues sea adecuado y tome menos tiempo. Ante esta problemática, la entidad bancaria propone que se usen herramientas de integración continua y un flujo basado en la metodología Kanban. Dentro de las herramientas propuestas están el uso de Bitbucket como repositorio, Git para el control de versiones y Jenkins para la ejecución de pipelines automatizados, así como el uso de un tablero Jira que cuente con las etapas del desarrollo sugeridas por la metodología Kanban. Como resultado del uso de las herramientas mencionadas, se van a realizar despliegues en un menor tiempo, permitiendo eficiencia operativa. Además, el uso de pipelines automatizados pueden reducir los errores en los pases a producción. Otros beneficios de este nuevo flujo son: el uso sencillo y el tiempo de capacitación a nuevos integrantes es menor

Waste and recycled textiles as reinforcements of building materials

Se describe el panorama del impacto provocado por las fibras textiles provenientes de los pantalones de mezclilla, así como sus diferentes usos una vez recicladas, en particular en los materiales de construcción.Currently the use of composite materials in the construction areas has had a great impact on the society. Mainly, those related with sustainability and environment aspects. Daily proposals aimed at overcoming the properties of traditional materials arise; which includes emergent materials either from waste or recycled products. One of them is related to textile materials, which including fibers such as wool, hemp, linen and cotton. In the last decade, special attention has been focused on the used clothes, which represent a source of raw materials environmentally responsible and economically profitable. Textile materials are discarded daily around the world, representing approximately 1.5% of the generated waste. Blue-jeans are the most used clothing in the world, they are elaborated by one of the most commonly used natural textile fibers, cotton. Textile materials have been reused in different applications, for example, in the production of poor quality wires, crushed to manufacture insulating materials noise and temperature, and as fillers or reinforcements of concrete. In this chapter, different topics are describing, including: a) Environmental impact of textile waste a result of massive consumption of clothing; b) Recycling and resuse of textile waste, and c) Waste and recycled textile materials used as building materials

Agency in mid-air interfaces

Touchless interfaces allow users to view, control and manipulate digital content without physically touching an interface. They are being explored in a wide range of application scenarios from medical surgery to car dashboard controllers. One aspect of touchless interaction that has not been explored to date is the Sense of Agency (SoA). The SoA refers to the subjective experience of voluntary control over actions in the external world. In this paper, we investigated the SoA in touchless systems using the intentional binding paradigm. We first compare touchless systems with physical interactions and then augmented different types of haptic feedback to explore how different outcome modalities influence users’ SoA. From our experiments, we demonstrated that an intentional binding effect is observed in both physical and touchless interactions with no statistical difference. Additionally, we found that haptic and auditory feedback help to increase SoA compared with visual feedback in touchless interfaces. We discuss these findings and identify design opportunities that take agency into consideration

¿Inclusión real o simulación? Estudio exploratorio de una campaña publicitaria para la comunidad gay en México

The gay community has generally been stereotyped and excluded from spaces in our society. This is reflected in political or commercial advertising campaigns, with those that have been inclusive being very scarce at a global level. With the aim of analyzing the mechanisms in the current dynamics of advertising campaigns, the present case study makes a literature review and a reflection on this social fact, addressing the feasibility and need to give voice to this community, making a critical analysis of the importance of being inclusive in today's society, suggesting a proposal based on Gross (2001) model applied in advertising campaigns for the gay community in Mexico, and Moreno (2006), that could lead to a huge potential for both Mexican companies and advertising agencies to address this community, not only as a market element, but also as an element of social justice. The results suggest that the existing gap in advertising is evident both in Mexico and Latin American context and including these communities seems to be relevant for both its economies and societies.La comunidad gay generalmente ha sido estereotipada y excluida de los espacios en nuestra sociedad. Esto se refleja en las campañas publicitarias políticas o comerciales, y las que han sido inclusivas son muy escasas a nivel mundial. Con el objetivo de reflexionar sobre qué y cómo serían los mecanismos bajo la comunidad gay percibe su diversidad e inclusión en la dinámica actual de las campañas publicitarias, y qué diseño de estos podría implementarse para una posible modificación de este escenario, el presente estudio de caso hace una revisión de la literatura y reflexión sobre este hecho social, abordando la viabilidad y la necesidad de dar voz a esta comunidad, haciendo un análisis crítico de la importancia de ser inclusivo en la sociedad actual, sugiriendo una propuesta basada en el modelo de Gross (2001) y Moreno (2006) aplicado en campañas publicitarias para comunidad gay en México, que podría conducir a un gran potencial tanto para empresas y agencias de publicidad el también dirigirse hacia esta comunidad, no solo como un elemento de mercado, sino también como elemento de justicia social. Los resultados sugieren que la brecha existente en la publicidad es evidente tanto en el contexto de México como en América Latina, e incluir estas comunidades se sugiere relevante tanto para sus economías como para sus sociedades

Effects on mechanical properties of recycled PET in cement-based composites

Concretes consisting of portland cement (OPC), silica sand, gravel, water, and recycled PET particles were developed. Specimens without PET particles were prepared for comparison. Curing times, PET particle sizes, and aggregate concentrations were varied. The compressive strength, compressive strain at yield point, and Young modulus were determined. Morphological and chemical compositions of recycled PET particles were seen in a scanning electron microscopy. Results show that smaller PET particle sizes in lower concentrations generate improvements on compressive strength and strain, and Young’s modulus decreases when the size of PET particles used was increased

Characterization of recycled polycarbonate from electronic waste and its use in hydraulic concrete: improvement of compressive performance

Artículo asociado a un proyecto de Doctorado en Ciencia de MaterialesTransparency, excellent toughness, thermal stability and a very good dimensional stability make Polycarbonate (PC) one of the most widely used engineering thermoplastics. Polycarbonate market include electronics, automotive, construction, optical media and packaging. One alternative for reducing the environmental pollution caused by polycarbonate from electronic waste (e-waste), is to use it in cement concretes. In this work, physical and chemical characterization of recycled polycarbonate from electronic waste was made, through the analysis by Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), energy dispersive spectroscopy (EDS) and scanning electron microscope (SEM). Then cement concrete was made with Portland cement, sand, gravel, water, and this recycled polycarbonate. Specimens without polycarbonate were produced for comparison purposes. The effect of the particle sizes and concentrations of recycled polycarbonate within the concrete, on the compressive strength and density was studied. Results show that compressive strength values and equilibrium density of concrete depend on the polycarbonate particle sizes and its concentrations; particularly the highest compressive strength values were 20% higher than that for concrete without polycarbonate particles. Moreover, morphological, structural and crystallinity characteristics of recycled polycarbonate, are suitable for to be mixed into concret
