The proposed system was used to implement a cognitive training program in users' homes, which was developed to be a low-cost tool with a high degree of user interactivity. The results of this preliminary study indicate that this user-friendly system could be adopted as a form of cognitive training for the elderly.

This paper presents a technical solution to improve accessibility in e‐learning platforms. The guidelines for the solution were concluded from the analysis of literature with the goal of achieving scalable, reusable, and easily manageable platforms. The method has been tested through a case study conducted on Moodle where a sample of the target population experimented it through several Engineering Education courses resulting in a high degree of perceived usefulness. We also found out that deaf students encountered less problems accessing the information than blind students due to different reasons.

Lighting is an essential element for modern life, promoting a sense of wellbeing for users. However, bad illumination may produce health problems such as headaches and fatigue, among other vision problems. For that reason, this paper proposes the development of a smartphone-based application to help in lighting evaluation to guarantee the compliance of illumination regulations and to help increase illuminance efficiency, reducing its energy consumption. To perform this evaluation, the smartphone can be used as a lighting measurement tool, evaluating those measurements through an intelligent agent based in rules capable of guiding the decision-making process. As a result, this tool allows the evaluation of the real working environment to guarantee lighting requirements, helping in the prevention of health problems derived from bad illumination and improving the lighting efficiency at the same time.
