“…These analogue drawing drawings cannot be digitally stored for later use, or used with other programmes or printers, lack system support such as undo, erase, retrieve, feedback, and are not efficient or suitable for complex drawing tasks. Some of the experimented digital drawing tools for graph, diagram, and drawing production as illustrated in Table 1 are SVG-Plott (Bornschein & Weber, 2017), AGC (Gardner et al, 2002), Maths Class (Cook & Polgar, 2015), BPLOT2 (Fujiyoshi et al, 2008) and BPLOT3 (Fujiyoshi et al, 2014), AHEAD (Rassmus-Grohn et al, 2007), Play with Geometry (Buzzi et al, 2015), Draw and Drag (Grussenmeyer, 2015), TactileView and TactiPad (Touch Graphics, 2016), and many more.…”

The representation of pictorial data by people who are blind and sight impaired has gathered momentum with research and development; however, little research has focused on the use of a screen layout to provide people who are blind and sight impaired users with the spatial orientation to create and reuse graphics. This article contributes an approach to navigating on the screen, manipulating computer graphics, and user-defined images. The technique described in this article enables features such as zooming, grouping, and drawing by calling primitive and user-defined shapes. It enables blind people to engage in and experience drawing and art production on their own. The navigation technique gives an initiative sense of autonomy with compass directions, makes it easy to learn, efficient to manipulate shape with a the simple drawing language, and takes less time to complete with system support features. An empirical evaluation was conducted to validate the suitability of the SETUP09 technique and to evaluate the accuracy, and efficiency of the navigation and drawing techniques proposed. The drawing experiment results confirmed high accuracy (88%) and efficiency among blind and visually impaired (BVI) users.

Abstract. In order to extend the usability of BPLOT, a new version BPLOT4 was developed. BPLOT is the first tactile graphics production system for the blind that enables the blind to produce tactile graphics by themselves. BPLOT4 has obtained the following four new features:(1) The usage of variables and mathematical formulas is supported for the description of plotter control commands. (2) The production of ink print graphics is possible at the same time as that of tactile graphics.

“…Cependant cette technique procure une représentation statique des schémas, et ne profite pas des avantages offerts par les systèmes informatisés. Les grands afficheurs braille peuvent potentiellement fournir une fonctionnalité similaire sur un système informatisé, mais leur coût est généralement prohibitif [3]. De plus, leur taille n'atteint pas celle d'une feuille A4.…”

RESUMENous proposons une nouvelle technique pour aider des personnesà explorer des formes géométriques sans l'aide de la vision. Cette technique est basée sur un guidage utilisant des icônes directionnelles affichées sur une matrice de picots. Il s'agit d'une alternativeà la méthode usuelle consistantà lever les picots correspondant aux pixels sombres autour du curseur. Dans cet article nous comparons deux méthodes d'exploration de formes géométriques avec notre nouvelle technique : en conditions unimanuelle et bimanuelle. D'après nos résultats, les utilisateurs ont fait peu d'erreurs dans les deux conditions. De plus les résultats montrent uneéquivalence des deux techniques en terme de temps de réponse et de confiance des utilisateurs en leur réponse. MOTS CLES :Interaction tactile, Tactons, Géométrie, Interaction non-visuelle. ABSTRACTWe propose a new technique to help people to explore geometric shapes without vision. This technique is based on a guidance using directional cues with a pin array. This is an alternative to the usual technique that consists of raising the pins corresponding to dark pixels around the cursor. In this paper we compare the exploration of geometric shapes with our new technique in unimanual and bimanual conditions. According to our results, the users made few errors in both conditions. Moreover the results show an equivalence for both techniques in answer time and users' confidence in their answer.
