Orientation and Mobility: Techniques for Independence

Wellbeing, independence and mobility: an introduction

The Influence of the Olfaction, Audition and Tactile Senses in Mobility and Orientation of Blinds

Objectives: The aim of this study is to evaluate the effects of olfaction, audition and tactile senses in mobility and orientation of blinds. Methods: The statistical sample of this research included 100 blind persons aged between 16 and 75 years (61 males and 39 females) with different level of education (16 persons lower than the diploma, 26 persons diploma, 46 persons bachelor, 12 person ...

Techniques for computing with low-independence randomness

During the past two decades, randomness has emerged as a central tool in the development of computational procedures. For example, there are many well known problems for which randomness can be used to design an algorithm that works well with high probability on all inputs, whereas the best known deterministic algorithms fail miserably on worst-case inputs. Unfortunately, generating truly rando...

Guidelines for Designing Mobility and Orientation Software for Blind Children

We present a study about the use of current electronic travel aids to help blind people navigate through familiar and unfamiliar environments. We also discuss the main strengths and weaknesses of electronic travel aids and propose guidelines to design and use them adequately. We provide a proposal to develop and use traveling aids. As a result, this can be a first step towards defining major as...

Girth, minimum degree, independence, and broadcast independence

An independent broadcast on a connected graph $G$is a function $f:V(G)to mathbb{N}_0$such that, for every vertex $x$ of $G$, the value $f(x)$ is at most the eccentricity of $x$ in $G$,and $f(x)>0$ implies that $f(y)=0$ for every vertex $y$ of $G$ within distance at most $f(x)$ from $x$.The broadcast independence number $alpha_b(G)$ of $G$is the largest weight $sumlimits_{xin V(G)}f(x)$of an ind...
