Creación de un sistema inclusivo adaptado a las personas con discapacidades en las extremidades superiores.

Abstract

According to the World Health Organization. WHO, about 15% of the population has a disability, either physical or intellectual, these people somehow face inequalities in the workplace, health, education, etc. In the case of having physical disabilities such as problems in their hands that prevent them from performing tasks either temporarily or permanently due to accidents or health problems, this prevents the manipulation of technological tools such as telephones, computers, etc. This project begins with the investigation of relevant information that helps to solve the problem posed, which is based on the lack of an operating system that provides tools to the user so he can manipulate the computer without using his hands. To carry out this project we used different free software tools such as, Linux Mint, Enable Eviacam, Google Assistant Desktop, Systemback, Virtual Keyboard. This project is important because it allows users with disabilities in the upper limbs access to technology by manipulating the operating system equipped with inclusive tools in this way can perform various activities such as surfing the web, watch news, videos etc. Thus, integrating themselves into modern life. The base system configurations consist of changing logos, starting applications at boot time and configuring views. One of the main tools is Enable Viacam which works as a mouse emulator through a webcam, this application allows to use the pointer by head movements, this allows to perform any operation, select, left and right click, move elements, select texts. Google Assistant is capable of answering questions asked by the user, informing about news, weather, etc. The virtual keyboard allows the user to write texts with the help of the virtual mouse. All these tools are configured to start automatically when the computer is turned on, especially eviacam since without this functionality the user will be unable to manipulate the computer. Finally, Systemback is used to create a virtual image of the operating system that can be started on different computers. For the development of this prototype the RAD. Rapid Application Development, methodology was used, which consists of 4 main phases. In the first one the prerequisites such as user stories are defined, 2, then the structure of the prototype schematics and tools to be used are defined and the implementation and configuration of the system is proceeded. 3, changes and improvements are made, 4, testing and delivery, in this last phase the relevant tests are performed, which consists of two phases, measuring the performance of the installed tools and user satisfaction when using the operating system. In the first phase, the system is found to be efficient as long as the equipment meets the following requirements, CPI of 1GHz, 2 GB of RAM, 20 GB of space, Resolution higher than 1024 x 768, it should be considered that it must be equipped with a webcam, for the operation of the virtual mouse. The second part of the evaluation used the Likert survey, which consists of ten questions, the respondents are people with problems in their hands that prevent them from manipulating a computer, the results that were found were satisfactory in general, however a weakness of the system is the writing because when using the virtual keyboard with the mouse, the writing process becomes slow so if they are long texts it becomes tedious, however when opening applications, play videos, send short messages is very efficient.
