An empirical evaluation of a graphics creation technique for blind and visually impaired individuals

Making Information Graphics Accessible for Visually Impaired Individuals

We propose a system that automatically extracts substantial information from graphics and generates multi-modal accessible representations for visually impaired individuals. Introduction Information graphics (line graphs, bar charts, pie charts, etc.) are increasingly pervasive in digital scientific literatures and business reports. Such visual depictions present a wide variety of quantitative ...

A Wearable Indoor Navigation System for Blind and Visually Impaired Individuals

A Tactile Palette to Translate Graphics for the Visually Impaired

Spatial haptic displays, such as electrostatic vibration (electrovibration) based friction displays, augment flat panels and surfaces with spatially arranged tactile content. Such devices can be useful for the visually impaired to translate visual images to tactile ones on demand. In this paper, we explore a tactile palette that consisted of a set of six perceptually distinct tactile stimuli co...

Evaluation of a world wide web scanning interface for blind and visually impaired users

1. Introduction This paper is concerned with the evaluation of a speech output Web browser for the blind and visually impaired, with special reference to how it supports users in building conceptual models of the World Wide Web in the way that sighted users do. The browser named BrookesTalk reads out the Web page, using speech synthesis, in word, sentence and paragraph mode and offers different...

development and implementation of an optimized control strategy for induction machine in an electric vehicle

in the area of automotive engineering there is a tendency to more electrification of power train. in this work control of an induction machine for the application of electric vehicle is investigated. through the changing operating point of the machine, adapting the rotor magnetization current seems to be useful to increase the machines efficiency. in the literature there are many approaches wh...
