- Blueeyes : easing the navigation and orientation of blind peoplePublication . Silva, Marta; Gomes, Anabela; Teixeira, Ana; Orvalho, JoaoAs reported by the World Health Organization (WHO), of the 7 billion people alive today, an estimated 253 million live with visual impairment that cannot be corrected with glasses or contact lenses. From these, 30 million blind or partially sighted persons live in Europe. Over the past years, blindness that is caused by diseases has decreased due to the success of public health actions. However, the number of blind people that are over 60 years old is increasing by 2 million per decade. Unfortunately, all these numbers are estimated to be doubled by 2020. With these facts, is necessary to bring awareness and understanding of the challenges blind people face and help to motivate research into new technology to answer those questions. This document starts to identify the challenges people with visual disabilities face in their life. The problem of navigation and orientation as well the different possibilities to deal with the locomotion situation is also addressed in this paper. It describes the traditional navigational solutions as well other which involves more sophisticated technological devices and their multimodal interfaces. The paper ends with the description of the BlueEyes project (Orvalho, 2016), consisting in a solution to help blind people moving in a city. The first phases of the project are described, and the actual research situations is also slightly explained.
- E-learning multimodal system for teaching and learning programmingPublication . Teixeira, Ana; Gomes, Anabela; Orvalho, JoaoThe high failure rates and abandonment are common in introductory programming courses in many higher education institutions worldwide. Different solutions have been proposed in literature trying to solve the problem but the situation remains virtually unchanged. Some members of this group also contributed with computer-based tools and different studies to understand and reduce this problem. Among the works carried out, the importance of investing in motivational aspects and the ability to solve problems is highlighted. This paper describes a new approach in order to contribute in solving this problem. The idea is to investigate the psychophysiological response of individuals during testing. The goal is to measure aspects of interest like the ability of abstraction, emotions, concentration, frustration, immersion, load/stress and cognitive level, in complex scenarios such as the resolution of programming problems. Thus, we intend to use new forms of interaction as Brain Computer Interfaces (BCI), eyetracking and other low-cost instruments (e.g.: BITalino) using body signals to extract information of interest. This information will be included in an e-learning system adapting its interface according to the users actions.
