Intuitive user interface (UI) for the Tactonom



Research on 2D multi-line tactile devices continuosly advances but the design of tactile UI design and their interaction possibilities does not progress likewise. Following a user-centered design methodology, the fellow will perform contextual inquiry (CI) analysis to collect efficiency reference values of common working practice (e.g. with single-line Braille displays) as well as general requirements. An accompanying longitude experiment will give more insights in haptic stimulation and perception. Usability tests will be applied to validate the UI design and the interaction methods with end users. Based on the results, strategies for presentation of different media types (diagram, tables, maps etc.) combined condensing, translating, iteratively presenting or navigating their information content will be developed.

Expected Results

Intuitive user interface for tactile display based on state-of-the-art understanding of haptics.

Presentation of ESR15

My name is Gaspar Ramôa, and I am from Portugal. I hold a master’s degree in Computer Science and Engineering at the University of Beira Interior, Portugal. I am passionate about health and fitness. Most of my personal and technical skills were obtained, in the last five years, as a young swimming and Modern triathlon athlete and as a university student. During my bachelor and master studies, I have worked in the fields of Robotics, Artificial Intelligence and Computer Vision. I built a portable low-powered system to help visually impaired people navigate in indoor environments in my master dissertation, entitled “Artificial Vision for Humans”, where I developed a specific ability to build user interface systems for blind people. I always had a great desire to take a PhD course in a European country other than mine, and thanks to the INTUITIVE H2020-MSCA-ITN project, I can finally fulfil my dream. I am confident that I can complete the research project successfully since I believe on my hardworking ability to achieve goals, I believe in my suitable background in computer engineering, and I have the motivation to improve visually impaired people’s life quality.
