As part of a project to improve human computer interaction mostly for blind users, a survey with 50 blind and 100 sighted users included a questionnaire about their user habits during everyday use of personal computers. Based on their answers, the most important functions and applications were selected and results of the two groups were compared. Special user habits and needs of blind users are...

Recently, there has been extensive research and development in the field of smart cars, including technologies related to autonomous driving. Various industries are actively working towards creating efficient safe self-driving cars. Sensor emerging prevent traffic accidents support driving complex environments where human perception may be limited. One representative being researched is use Fre...

In this paper, we propose a fast time-frequency mask technique that relies on the sparseness of source signals for blind separation (BSS) to separate mixture two input sounds in single signal automatically. Due signals, can be distinguished when it is transformed into domain. Most previous methods did not mention effect different angles accuracy. To overcome such problems, first define features...

While graphical interfaces have provided a host of advantages to the majority of computer users, they have created a significant barrier to blind computer users. To meet the needs of these users, a methodology for transforming graphical interfaces into nonvisual interfaces has been developed. In this design, the salient components of graphical interfaces are transformed into auditory interfaces...

Subjek Mahasiswa Tunanetra ( Totally Blind) Semester II Jurusan Pendidikan Khusus Fakultas Keguruan Ilmu Universitas Sulta...

We describe an Action-by-Design-Component (ADC) framework to guide auditory interface designers for exploratory data analysis. The framework characterizes data interaction in the auditory mode as a set of Auditory Information Seeking Actions (AISAs). Contrasting AISAs with actions in visualizations, the framework also discusses design considerations for a set of Design Components to support AIS...

This paper integrates our contributions in the domain of blind source separation (BSS) and blind source deconvolution (BSD) both in static and dynamic environments. We focus on the use of the state space formulation and the development of a generalized optimization framework, using Kullback-Liebler divergence as the performance measure subject to the constraints of a state space representation....

Research on spatial cognition and blind navigation suggests that a device aimed at helping blind people to shop independently should provide the shopper with effective interfaces to the locomotor and haptic spaces of the supermarket. In this article, we argue that robots can act as effective interfaces to haptic and locomotor spaces in modern supermarkets. We also present the design and evaluat...

Independent grocery shopping is one of the most functionally challenging tasks for visually impaired and blind individuals. Many assistive shopping systems have been developed to address the problem of blind grocery shopping. In this article, we identify several design requirements for assistive shopping systems and analyze existing approaches to see how well they meet them. Our objective is to...
