My name is Lawrence Obiuwevwi, and I am from Nigeria. I had my bachelor’s degree in electrical engineering from the  University of Nigeria, Nsukka (UNN)   in Nigeria. My bachelor’s thesis was on “design and implementation of a wireless electrical doorbell.” I proceeded to publish its  journal version . After completing my bachelors, I did an engineering fellowship with Engineering for Change  (E4C) ,  an  Autodesk Foundation  sponsored program for young engineers, where I worked with a Spain-based company,  Solaris Offgrid ,  on building a smart reusable battery module to help power rural homes across the globe. The technology aims to revolutionize the use of rechargeable battery modules through hardware design and programming. My love for computer science is fueled by the ease with which we can build some wonderful products from readily available computing systems like computers, software, and data. I love the idea of interacting with comput...

How we portray and engage with the world around us is fundamentally influenced by our sense of vision. The visual area is located in about one-third of the cortical surface of the primates. Vision loss, either at birth or much later in life, affects how we perceive the world. It is intriguing to know how the brain of sighted and blind individuals differ. In the  paper  "The nature of consciousness in the visually deprived brain," the authors  Ron Kupers ,  Pietro Pietrini ,  Emiliano Ricciardi , and  Maurice Ptito  discuss various topics pertaining to the nature of consciousness in those without vision. This research answered an important question: What can we learn about the functional development of the human brain in physiological conditions by studying blindness?    (Source:  https://doi.org/10.3389/fpsyg.2011.00019 ) There are some findings from research on animals as well as from psychophysical and functional brain imaging studies ...

The research work addressed in the paper "Methodology for heuristic evaluation of the accessibility of statistical charts for people with low vision and color vision deficiency," published by Rubén Alcaraz Martínez , Mireia Ribera , Toni Granollers Saltiveri (2021), focuses on formulating a set of heuristics to assess statistical chart's usability while concentrating on the requirements of those with low vision (LV) and color vision deficiency (CVD). To do this, the authors created a set of heuristics based on the methodology defined by Quiñones et al.  in the paper "A methodology to develop usability/user experience heuristics". The authors conducted two evaluations after establishing the first version of the set of heuristics (17 indicators). Following the assessments, the authors expanded the list to 18 indicators, and other changes were made, including a more straightforward scoring system and additional documentation for evaluators. This study was the fi...
