Crescere a Trento. Indagine sui servizi socio-educativi per la prima infanzia
No full textNel primo semestre del 2010, il Dipartimento di Sociologia e Ricerca Sociale e il Servizio servizi all’Infanzia, Istruzione e Sport del Comune di Trento - in collaborazione con numerosi altri soggetti – hanno avviato e svolto l’indagine Crescere a Trento, sui servizi socio-educativi per la prima infanzia nel Comune di Trento. La ricerca era orientata a raccogliere dati utili per un’analisi su come le famiglie con bambine e bambini piccoli si organizzano per la loro cura ed educazione, sul bisogno di servizi e interventi per la prima infanzia, sui livelli di soddisfazione per i servizi esistenti, sulle ragioni della non frequenza dei nidi d’infanzia. La rilevazione ha coinvolto un campione probabilistico di famiglie, rappresentativo della popolazione di interesse. Il ricorso a un disegno di ricerca mixed-mode (questionario auto compilato via web, intervista telefonica, intervista faccia-a-faccia) fa di questa indagine anche un interessante esperimento metodologico. Questo quaderno presenta i principali risultati della ricerca e la metodologia adottata per l’indagine
Investigating mobile learning and accessibility for blind users
No full textMobile devices are increasingly used for multiple purposes in everyday activities such as business, study and learning, entertainment and games. Blind people especially may benefit from distance learning, which removes mobility constraints allowing interaction anytime, anywhere, at any pace. In this process the user interface plays a key role. Interaction should be operable, simple and satisfying for anyone including persons with special needs who rely on assistive technology. In this paper we analyze accessibility issues encountered by blind users when interacting with learning applications on mobile devices, with special attention to touch screen technology, specifically oriented to visual information. Examples show issues and possible solutions to support the learning process, and alternative interaction modalities are discussed
Playing with geometry: a multimodal Android App for blind children
No full textGeometry is a traditionally difficult subject to teach to visually impaired subjects. This paper investigates tools to help blind children learn geometry. An accessible vibro-tactile-based android application has been designed to allow children to make freehand drawings and play with geometry, recognizing common geometric shapes or topological configurations. An initial usability test of the application, performed by a blind researcher, has revealed some limitations of the proposed approach that could soon be overcome thanks to current technological innovation in the mobile world
Making Wikipedia editing easier for the blind
No full textA key feature of Web 2.0 is the possibility of sharing, creating and editing on-line content. This approach is increasingly used in learning environments to favor interaction and cooperation among students. These functions should be accessible as well as easy to use for all participants. Unfortunately accessibility and usability issues still exist for Web 2.0-based applications. For instance, Wikipedia presents many difficulties for the blind. In this paper we discuss a possible solution for simplifying the Wikipedia editing page when interacting via screen reader. Building an editing interface that conforms to W3C ARIA (Accessible Rich Internet Applications) recommendations would overcome accessibility and usability problems that prevent blind users from actively contributing to Wikipedia
Improving interaction via screen reader using ARIA: an example
No full textAn interface conforming to W3C ARIA (Accessible Rich Internet Applications) suite would overcome many accessibility and usability problems that prevent blind users from actively contributing to collaborative knowledge. In a previous phase of our study we identified problems of interaction via screen reader with Wikipedia, then proposed an ARIA-based modified Wikipedia editing page. The new user interface (UI) is functionally equivalent to the original Wikipedia editing page, and its appearance is very similar (apart from an additional combobox instead of a list of links), but usability is greatly enhanced. In this demo we will show interaction via Jaws screen reader using both the original and the proposed Wikipedia editing pages
Interacting with mobile devices via VoiceOver
No full textIn this paper we analyze the interaction of blind users with Apple touchscreen devices iPad, iPhone and iPod touch, accessible to the visually-impaired thanks to their pre-installed VoiceOver screen reader or magnifier. Specifically, we focus on the gestures offered by VoiceOver to simplify interaction for blind users. A usability inspection of the devices? user interfaces has been performed and integrated with user feedback collected via an online survey taken by 55 totally blind users. Results confirm that VoiceOver makes the Apple devices basically accessible to blind users, but there are still some issues related to usability. Users normally believe that accessibility integrated with VoiceOver is an important innovation, but some operations, such as the writing of long text, take too long or are not comfortable. Results suggest that a multimodal approach on mobile touchscreen devices does not offer a simple and satisfactory interaction paradigm for all and it deserves further investigation. Three possible solutions for improving user interface interaction and offering a simpler and more comfortable experience for blind individuals were proposed to the survey participants, gathering their positive feedback
Enhancing Wikipedia editing with WAI-ARIA
No full textNowadays Web 2.0 applications allow anyone to create, share and edit on-line content, but accessibility and usability issues still exist. For instance, Wikipedia presents many difficulties for blind users, especially when they want to write or edit articles. In a previous stage of our study we proposed and discussed how to apply the W3C ARIA suite to simplify the Wikipedia editing page when interacting via screen reader. In this paper we present the results of a user test involving totally blind end-users as they interacted with both the original and the modified Wikipedia editing pages. Specifically, the purpose of the test was to compare the editing and formatting process for original and ARIA-implemented Wikipedia user interfaces, and to evaluate the improvements
Accessing e-Learning Systems via Screen Reader: An Example
No full textThe evolution of the Information and Communication Technology (ICT) and the rapid growth of the Internet have impelled the pervasive diffusion of e-Learning systems. This is a great opportunity for visually-disabled people provided that both the interactive environment, created by the Learning Management Systems, and the Learning Objects, created by teachers, are properly designed and delivered. In this paper we investigate interaction of the blind user with an open source Virtual Learning Environment (Moodle) and discuss how the use of the W3C Accessible Rich Internet Applications (ARIA) suite may improve the experience of navigation via screen reader
