چکیده
A symbolic language called Blissymbolics has been gaining in popularity in recent years as an alternative means of com munication 63 for verbally impaired, cerebral palsied children. Since m any of these children are also severely physically handicapped, some m eans of indicating and storing symbol selections must be provided . This paper describes a collaborative project to develop a graphics te rminal which will display Blissymbol messages on a home television set . The microprocessor-based equipment is being designed to accep t a variety of input controls and output devices in order to match indiv idual needs. The user makes selections interactively from a "page" of symbols displayed on two-thirds of the TV screen. The remaining one-th ird of the screen is available for the user's message, which can then be transmitted to other terminals in a classroom, for exampl e, or over the telephone. The rationale for selection of the SOo-symbol vocabulary, and its division into pages, will also be described. D~VELOPPEMENT D'UN TERMINAL POUR BLISSYMBOLES: AFFICHAGE ~L~V IS~ INTERACTIF POUR ~HAUSSER LES COMMUNICATIONS POUR PERSONNES PHYSIQUEMENT HANDICAP~ES Dans les annees courantes, un langage symbolique surnomme "Blissymbolics" a atteint une hausse en popularite comme un moyen alternatif de communication pour les enfants aphysiques a tteints d'infirmite motrice cerebrale. Puisque plusieurs de ces enfants sont gravement handicapes physiquement, des moyens pour indiqu er et emmagasiner des selections de symboles doivent etre prevus. Ce tte communication decrit un projet, execute en collaboration, qui a pour but de developper un terminal graphique qui affichera des messag es en "fHi9symbols" sur un ecran de television. Le systeme qui est entrain d'etre mis A point est base sur un micro-processeur. Celui-ci acceptera une variet~ de controles d'entree et des appareils a la sortie afin de satisfaire aux besoins individuels. L'Operateur fait des selections reciproquement A partir d'une page de symboles affichee sur les deux tiers de l'ecran de television. Le dernier tier de l'ecran sert a l'affichage du message selectionne par l'operateur qui peut ensuite etre transmis I d'autres "Blissterms" dans la sal le de classe ou meme encore par telephone I des usagers eloignes. La raison fondamentale pour la selection du vocabulaire comportant 500 s ymboles ainsi que sa pagination seront aussi decrits dans cet ouvrage.
