For blind individuals who wish to live independently, this study develops an automatic generation tool for tactile graphics of characters. The tool is developed by using the tactile graphics production system BPLOT. The tool generates character ...

We have devised a novel “Point-and-Tap” interface that enables people who are blind or visually impaired (BVI) to easily acquire multiple levels of information about tactile graphics and 3D models. The interface uses an iPhone’s depth and color ...

Blind and visually impaired (BVI) people primarily rely on non-visual senses to interact with a physical environment.  Doing so requires a high cognitive load to perceive and memorize the presence of a large set of objects, such as at home or in a ...

Tactile Graphics (TG) are raised line diagrams to represent pictorial content for People with Visual Impairments (PVI). While shapes may be simple to depict, objects often appear disjunctive when represented in graphics. Researchers have evaluated the ...

Graphical representation of mathematical functions is often inaccessible to blind people. There are methods to convert graphs into a tactile form, but this requires assistance, apart from manufacturing time and cost. In this paper, we present a ...

Accessing graphical information is a challenge for persons with individuals with blindness and visual impairment (BVI). The primary method for making graphical information more accessible to BVI is to translate visual graphics into tactile ...

In this article a collaborative workstation for creating audio-tactile graphics is presented. The system is based on a common open source office suite and supports a transcriber for tactile graphics with several tools. In addition the system ...

Graphic contents are important resources to communicate information and their use is fundamental in the teaching process. Visually impaired people do not have easy access to this resource owing to their impairment. They mainly use tactile graphics ...

Most of the braille embossers incorporate a mode for the creation of braille embossed graphics (BEG). Some of them can produce dots in different elevations, but also various dot densities. Dot elevation and dot density constitute the main ...

The visually impaired must obtain shape information in a tactile manner. However, existing conventional graphics are static. We prepared a more useful, dynamic tactile display; we aimed to allow the visually impaired to recognize and draw figures ...

The conventional tactile diagrams for the visually impaired people are usually limited to a finite number of annotations and its associated Braille legend can extend to several pages. This in turn makes the tactile books bulky and cumbersome. To address ...

Tactile graphics play an essential role in knowledge transfer for blind people. The tactile exploration of these graphics is often challenging because of the cognitive load caused by physiological constraints and their complexity. The coupling of ...

Consistency over multiple images is a central requirement in most guidelines for creating tactile graphics. By contrast, tactile consistency over multiple production media for tactile graphics is not very common. In this article, we describe a user-...

We describe the novel BrailleDis 9000 pin-matrix device. The refreshable device allows to present tactile graphics on a matrix of 60 times 120 pins. The pin-matrix device is made up of a newly developed type of vertical Braille module allowing for a ...

Information on the World Wide Web becomes more and more important for our society. For blind people this is a chance to access more information for their everyday life. In this paper we propose novel methods to present web pages including graphical ...
