Auditory signals are used for various purposes; e.g. signaling danger, warning of malfunction, notification of an incoming message, operational feedback, and indicating the beginning and end of an operation. These sounds should be designed to convey messages. Auditory signals are useful for people with normal senses and are essential for the blind. The universal design of auditory signals would...

This paper proposes a concept to use a 2D tactile mind map tool for a better integration of blind people into co-located meetings with the goal of structuring and organizing ideas during ideation. We mainly focus on presentation techniques to present mind maps to blind users. We discuss problems of existing analogue and digital tools, which support structuring and organizing ideas, for blind me...

The proliferation of graphical user interfaces has had a dramatic impact on the ability of the blind to work as programmers. It is particularly difficult for the blind to design forms for programs written in Visual Basic. A scripting language is introduced that enables the blind to create Visual Basic forms without the need to specify all the detailed information that Visual Basic requires and ...

Absract Introduction: Blindness is among the most severe of all forms of physical disability. Without vision, blind people are cut off from a major segment of the social and physical environment to which they must adapt. This creates problems for mobility and everyday skilled activities for which vision is important. At the same time, in relating to other people, the blind can only guess at the...

Abstract The screw-blind riveting combines direct screwing with the blind riveting. novel joining element can be integrated into every injection-molded component like a standard screw boss without significantly increasing processing time. screw-blind-rivet (SBR) consists of connected to substrate by thin sleeve. process screw-blind-riveting divided two phases. first is screw-in phase. secured S...

Top-down and bottom-up processing are two distinct yet highly interactive modes of neuronal activity underlying normal and abnormal human cognition. Here we characterize the dynamic processes that contribute to these two modes of cognitive operation. We used a blind source separation algorithm called second-order blind identification (SOBI [1]) to extract from high-density scalp EEG (128 channe...

iii The methodology exploited to evaluate the performance of the framework involves the development of algorithms, their implementation in software, and their assessment using welldesigned experiments anchored on quantitative performance measurement methods. The goodness-of-fit coefficient (GFC) is used to evaluate the performance of the framework, by measuring the degree of similarity between ...

We used magnitude estimation to determine preferred datato-display mappings, polarities, and psychophysical scaling functions relating perceptual and conceptual data values to underlying acoustic parameters for blind and visually impaired listeners. We compare the resulting scaling functions to previous findings with sighted participants [1]. The findings have implications for the design of fut...
