Item type:Publication, Low-Cost Interfaces and Technological Accessibility: A Human–Computer Interaction Approach for the Inclusion of Individuals with Motor Disabilities(Springer Nature Switzerland, 2026); ; ; ; Cerebral palsy (CP) is a neurological disorder of prenatal or perinatal origin that affects motor control, posture, and frequently speech, thereby limiting autonomy and social participation among individuals who experience it. During the transition to adulthood, these limitations tend to intensify, highlighting the need for assistive technologies (AT) that effectively address real-world contexts of use. However, the high cost and limited adaptability of many existing solutions restrict their adoption, particularly in low- and middle-income countries. This study is situated within the field of Human–Computer Interaction (HCI) and aims to evaluate low-cost input devices based on principles of accessibility, ergonomics, and usability, to improve the work performance of individuals with motor disabilities. A qualitative methodology was employed, based on the think-aloud technique, applied to a case study involving an adult with cerebral palsy who interacted with three devices: a conventional trackpad, a MAKEY MAKEY-based interface, and a wireless keyboard with an integrated touchpad. The results indicate that, although the trackpad allows for a degree of progressive adaptation, it presents limitations in tasks requiring bimanual coordination. The MAKEY MAKEY interface provides greater discrete control but demands high levels of coordination and generates fatigue due to its physical configuration. In contrast, the wireless keyboard with an integrated touchpad emerges as the most efficient and ergonomic alternative, as it distributes functions between both hands and reduces physical effort. It is concluded that the adaptation of mass-market consumer technologies, under a user-centered design approach, can offer accessible, functional, and sustainable solutions for the digital inclusion of individuals with motor disabilities. © The Author(s), under exclusive license to Springer Nature Switzerland AG 2026. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Smart Signage with Augmented Reality: Inclusive CoworkingThis project focuses on the implementation of augmented reality signage designed to enhance user experience in a coworking space. The signage integrates 2D animations and virtual tours to provide an intuitive and immersive experience, from entry to the desired destination within the establishment. At the main entrance, a totem with a coworking directory features a QR code that visitors can scan to access an interactive directory. The 2D animations, thoughtfully designed with an inclusive approach, utilize validated corporate colors to ensure accessibility, especially for individuals with color vision deficiencies. Each business in the coworking space is identified by a unique corporate color, and internal business floor plans use analogous colors, adjusted to maintain aesthetic coherence and accessibility. In addition to being an effective navigation tool, these animations reinforce the visual identity of the coworking space. Each business within the establishment has an interactive virtual tour that guides visitors from entry to their final destination, providing real-time visual information for effective orientation. The signage system is based on WordPress to offer a seamless and efficient experience without the need to download a specific application. Upon scanning the QR code, users are redirected to a mobile-optimized web page. This page not only provides access to the 2D animations and virtual tours but also offers useful information such as business hours, links to the businesses’ and coworking space's social media, and other relevant details for the visit. This augmented reality signage approach not only enhances the functionality of the space but also ensures that all visitors, regardless of their needs, enjoy an inclusive and efficient experience in the coworking space.20 - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Promoting Water Culture Through Augmented Reality and Gamified Experiences(2025); ; ; Marcos Chacón-CastroThis article examines the design and development process of interactive and immersive learning environments focused on conservation, management and responsible use of water. Using the Game Thinking methodology, interdisciplinary groups were formed, consisting of students from three different Master’s programs, along with designers, programmers, experts from the Quito Metropolitan Public Water and Sanitation Company (EPMAPS), and members of Foundation for the Support of Sustainable Development in Ecuador (FADSE). A total of 135 participants contributed diverse perspectives in education, user experience, technology, and sustainability. The objective was to develop proposals that would connect with children, young people, and adults to raise awareness about responsible water use, the consequences of waste, the contamination of water sources and simulate the consequences of water decisions in urban and rural environments. The study demonstrated that master’s students can play a significant role in addressing real urban challenges and that, when properly guided, their ideas can lead to innovative solutions aligned with emerging technologies. The developed solutions were evaluated by the students themselves alongside their peers, revealing that interactive tools not only promote active participation but also strengthen the emotional connection with the new water culture. Furthermore, the project emphasized accessibility, scalability, and cultural relevance, ensuring inclusive and sustainable educational solutions. In the future, the study will aim to assess the impact of these initiatives on public awareness and behavior.24 - Some of the metrics are blocked by yourconsent settings
