      In Peru, the Instituto Nacional de Rehabilitación (INR) is one of the centers that treats people with disabilities. In 2013, 49.88% of its attended patients had ages between 0 and 9 years, and 0.81% from 18 092 patients have been diagnosed as children with Cerebral Palsy (CP). Given such demand and despite the efforts to solve this problem, access to a number of analyses to treat this disability is hindered, particularly, the knee kinematics analysis of children with CP, which is the subject of our research. To perform this analysis, the INR uses its gait laboratory; the problem is that it requires complex equipment, a big budget, and highly-trained personnel. This study proposes a tool, implemented in a gait reeducation center, that allows to quantify the measurement of angles of the kinematic analysis of the knee, based on Image Processing and Kinect, which is a device for simple, portable and economical use.The characteristics of this application have been raised with the support of Ítala Zegarra, physical therapy specialist, who laid the foundation for its development. Likewise, the reports of the patients' progress, obtained from the application, were established with the help of a team of specialists in physiotherapy led by Ítala Zegarra.For the validation of the tool’s accuracy, one subject with normal gait has been evaluated in terms of kinematic analysis of the knee. The analysis was simultaneously developed between the Vicon System, 3D gold-standard in the market, and the present tool, 2D system, over the same patient. The measurement results were very similar between both systems, obtaining a R2 of 0.93, approximate value to those obtained by the Vicon system. Later, the tool was applied in children with Cerebral Palsy, proving that it helps to increase the accessibility of its treatment. In conclusion, Kinect is a low cost alternative for capturing knee angles of children with CP, which offers a 2D kinematics analysis.

      El presente proyecto se basa en el diseño e implementación de un prototipo e interfaz hombre-máquina que permite, a las personas con discapacidad de miembros superiores, utilizar Entornos de Mensajería Instantánea (EMI) como Telegram, mediante el uso de los músculos oculares. En ese sentido, se desarrolló hardware y software adecuado para la adquisición y procesamiento de señales electrooculográficas, originadas por el movimiento ocular de las personas. Asimismo se implementó un teclado virtual que permite, a los usuarios, seleccionar, mediante guiños, los botones que deseen para construir mensajes que, luego, son transmitidos por el EMI empleado. Para su correcto entendimiento, este informe se divide en cinco capítulos. En el primer capítulo se presenta la problemática y justificación del desarrollo del proyecto. El segundo, trata los conceptos y teorías utilizadas. En el tercero y cuarto, se explican las características del diseño e implementación de la etapa de hardware y software, respectivamente. Finalmente, en el último capítulo se muestran los resultados obtenidos, y sus validaciones. Al finalizar el proyecto se concluyó que este prototipo puede ser adaptado a las personas con limitaciones motoras en miembros superiores, con el fin de hacerlas partícipes de las diversas aplicaciones de comunicación a distancia desarrolladas en la actualidad.

    • EPOC

      Pérez Pichis, Roy; Sifuentes Palomino, Piero Rodrigo; Alarcón Morales, André Jesús (Universidad Peruana de Ciencias Aplicadas (UPC), 2015-06-01)
      Although Information Technology and Communication (ICT) are now a regular feature in the daily activities of most people, it is people with disabilities which have found various barriers to interact with the technology that surrounds them, so some of them need assistance either to use a television or manipulate a computer. The company Emotiv presented a novel means of interaction between humans and computers, the Emotiv EPOC, with which you can perform different actions through applications that connect with this tool. These actions are characterized by being controlled or managed by impulses produced by the brain to capture thoughts, feelings and expressions of a person; ie through certain thoughts you can control the functions of the applications. The "EPOC" project was created to address a solution to the constraints that people with disabilities found interacting with different technologies. To implement the above, a series of investigations will be made about the BCI technology, how they work, existing types, definitions and tools available. Then, we are going to investigate the Emotiv EPOC to understand its operation, what is the state of the art, what they are your technical requirements and a thorough investigation of its software development kit (SDK). We analyze the current context, behaviors, daily tasks performed by people with disabilities and their current interaction with technology. Finally, based on information collected, we will make three applications that connect the Emotiv EPOC with various technologies. All this, with the main objective to investigate the potential of Emotiv EPOC as a means of controlling various technologies.

    • Proyecto Iris

      Since year 2011, there is a quest for social inclusion of all people within the country. Part of this inclusion also considers people who have a disability that hinders them perform common activities of daily life. The search for a greater share of this population has been boosted further with the statement of the Law No. 29973, enacted on 2012, Ley de Personas con Discapacidad, which promotes the inclusion of people with disabilities, which represents nearly 6% of the total population of Peru, in the political, economic, social, cultural and technological aspects. This creates the need to know and find out what options are on the market to ease the adaptation and inclusion of these people in the various aspects mentioned and enhance their lifestyle. People with visual disabilities have many ways of communicating like the Braille system. Thanks to the massification of instant messaging on social networks and the mobile explosion, we can create new ways of interacting and make communication more accessible for this people using the Braille system. In this project we propose the develop of an application that allows these people with disabilities to communicate via a tablet. This will be possible, thanks to an Instant Messaging system and a braille keyboard. The visually impaired person can navigate the application thanks to the Screen Reader technology, which enables the person to understand how to navigate without seeing the screen. This document describes the development of the project with five chapters: description of the declaration and project planification – Descripción del Proyecto –, the principal concepts on which the project is based on – Marco Teórico –, the investigation of related past projects - Estado del Arte -, the project architecture – Arquitectura del Proyecto –, the methodologies and technology used in the project – Desarrollo del Proyecto –, and the results of the project and it's management – Gestión del Proyecto –. Finally, conclusions and recommendations are detailed.

      Although education is recognized as a fundamental human right, many e-learning platforms are not easy to use for people with visual impairment. Certainly there are a lot of accessibility tools that allow people with partial or total blindness to interact with computers and other devices, but e-learning platforms like Moodle have not included support tools for people with total blindness in their systems, especially in the mobile version. The “Adaptive Solution for people with visual impairment to participate in the learning process through Moodle platform” project seeks to provide easy access to content resources that teachers give to their students, besides to facilitate communication with their classmates and teachers. To perform the above, many interviews and investigations will be conducted to understand how people with visual impairment use mobile devices. Then, based on gathered information, prototypes specially designed for people with visual impairment will be made. Finally, the solution, which will be tested with real users with visual impairment to ensure that the application has the expected quality, will be implemented. All of these with the main goal of ensure that the student with visual impairment can be part of the learning process with the same opportunities as any other student. The implementation of the solution will include the development of a mobile application for iOS 7 platform and above, since it is one of the most advanced platforms in accessibility terms, in addition to web services that will provide information to the mobile application. Those services will be integrated with Moodle and will expose the information in a suitable format to be directly consumed by the mobile application.
