Leduc & Grenier (2015) examine the question of technology in relation to representations associated with deafness and aging. Their research contributes to challenging both the view of aging as a synonym for dependence or decline and the view of deafness as a disability. Their data include interviews with deaf seniors in Quebec Sign Language (LSQ) and in American Sign Language (ASL) (see http://actproject.ca/act/les-aines-sourds-et-latechnologie/). In parallel, the CLARe network proposes to contrast different approaches to the language of the elderly (Whitehouse 2013; Van der Linden & Juillerat Van der Linden 2014). Linguistic description, based on corpora of semi-guided interviews, focuses on the markers of typical aging and the compensatory and adaptive strategies used to achieve successful interactions (Bolly & Boutet to appear; Bolly & Thomas 2015). This approach takes into account the pragmatic dimension, including the multimodality of French, therefore considering a spoken language as an embodied language. Like Grenier and Leduc, this approach contests the view of aging as a decline (Baltes & Lindenberg 1997; Duboisdindien 2017). Work on sign languages was integrated into the data session of the 2nd CLARe workshop (Louvain), in connection with recently established corpora of LSFB (the sign language of French-speaking Belgium) and LSQ – both of which include data from elderly signers (Meurant 2015; Parisot & Rinfret 2015; Luna 2015). The SignAge project aims to create a corpus of interactions between elderly deaf signers (> 65 y.o) in French Sign Language (LSF) on the themes of the evolution of transport, access to care, culture and new technologies. As part of this project, we aim to test motion capture systems to complement analysis on the basis of video recordings. We expect motion capture to give us additional kinesiological information, allowing for articulatory measurements to study the use of space and the signers’ prosody, especially in interaction patterns. The literature indicates that the elderly use gestures with reduced amplitude (Carmeli, et al., 2003). We will also consider eye and hand coordination, which appears to be deficient for the elderly, as well as the forms of manual configurations. We will examine a possible link with peripheral dysarthria for co-verbal gestures or dyspraxia. Does reduced amplitude of gestures change their meaning? In the longer term, our aim is a more general study of (i) the linguistic specificities of LSF with respect to age in the productions collected in interaction (speech turn, signing space, lexical and morphosyntactic variations, prosody in LSF), (ii) the possible markers of aging, whether ordinary or disturbed, in connection with existing studies on the articulatory manifestations of language or cognitive disorders (Tyrone & Woll 2008; Tyrone 2014) and (iii) adaptive strategies of elderly signers. We follow some of the steps from the methodological protocol developed in the European project CorpAGEst (http://corpagest.org/): collection and processing of audiovisual data of the sample, annotation of segmental and suprasegmental markers (via the ELAN annotation software http://www.lat-mpi.eu/tools/elan), experimental study based on motion capture, functional linguistic interpretation of the results obtained. We had to adapt some of the recommendations to deafness. In the longer term, consideration will be given to adapting psychometric tests to deaf signers in order to diagnose participants’ risk of developing some cognitive impairment involving communication. We will present (i) our methodology and initial data (collected with two digital video cameras and a kinect, Figure1) and (ii) our adaptation of the original protocol to our research conditions (deaf participants) and the experimental issues. We also plan complementary tests with other types of sensors, such as accelerometers or digital gloves. We would like to take the opportunity of CLARe3 to submit these experimental tracks to the interdisciplinary expertise of the network members.
