User-Interface Modelling for Blind Users

Abstract

Abstract. The design of a user interface usable by blind people sets specific usability requirements that are unnecessary for sighted users. These requirements focus on task adequacy, dimensional trade-off, behaviour equivalence, semantic loss avoidance and device-independency. Consequently, the development of human-computer interfaces (HCI) that are based on task, domain, dialog, presentation, platform and user models has to be modified to take into account these requirements. This paper presents a user interface model for blind people, which incorporates these usability requirements into the above HCI models. A framework implementing the model has been developed and implemented in an electronic speaking bilingual software environment for blind or visually impaired people and in an educational system for children with special educational needs.

Asistované prostredie pre nevidiacich : bývanie, pracovisko a počítač

“…Osobné počítače, tablety a mobilné telefóny sa stali neoddeliteľnou súčasťou života moderného človeka. Preto je vývoj pomôcok pre nevidiacich orientovaný aj na asistenčný softvér, sprístupňujúci operačné systémy (ďalej OS) pomocou syntetickej reči alebo hmatového výstupu [86,88,89,90,91]. Mobilné počítačové stanice vybavené asistenčným softvérom nevidiacim otvárajú priestor sprostredkovaný internetom, čím sa podieľajú aj na ich sociálnom začleňovaní [82,83].…”

“…Nové technické možnosti využitia hlasových a hmatových výstupných periférií otvorili pre nevidiacich v oblasti informatiky ďalšie smerovania ich profesionality. Vykonali sa viaceré štúdie, ktoré poukazujú na sofistikované rozhrania umožňujúce nevidiacim v tejto oblasti plnohodnotné uplatnenie [88,89,90,91,100,101,102,103,104].…”

RUDO: A Home Ambient Intelligence System for Blind People

“…This representation of the world in which they live and interact can be transformed into general principles and reflected in computer-generated virtual environments. That is why in the case of the blind there are specific approaches to the design of user interfaces based on specific usability requirements that are unnecessary for sighted users [ 57 , 58 ].…”

Adapting modeling environments to domain specific interactions

“…One would expect that user interfaces and interaction be explicitly part of the development of modeling environments. For instance, works such as [17,106] strive to expand user interactions beyond that of traditional means, in ways to tackle UX issues and grasp other requirements and ways of expressing user interactions. Still, very little effort has been done in tackling how to describe interaction and its influence on the productivity of modeling environments, as discussed during the panel session of the MoDELS 2016 conference [9].…”
