International audience ; For almost ten years, the marketing of low cost motion capture devices such as the Microsoft Kinect sensor has enabled numerous studies in real-life settings (Mousavi Hondori & Khademi, 2014; Webster & Celik, 2014; Springer & Yogev Seligmann, 2016). Whereas most of this work with elderly people is studying gait and fall risks (see Rougier, Auvinet, Rousseau, Mignotte, & Meunier, 2011 for example), in the present paper we propose to focus on the building of the SignAge corpus dedicated to the study of signing in elderly deaf participants with low cost motion capture devices. Up to now, a (preferably multi-)camera setup was considered a basic requirement in sign language studies, sometimes completed with much more intrusive or expensive equipment such as data gloves, optical motion capture systems (Channon, 2015, p. 132–133). But latest technology advancements allow us to quantify 3D-motions and their time derivatives at a reasonable price. Our newly built SignAge corpus1 of interactions between elderly deaf signers in LSF takes advantage of such advancements. The SignAge corpus combines data acquired by: - 2 digital video cameras, with a plan on the signing interviewee’s upper body and a plan on the whole interaction (similarly to the protocol developed in CorpAGEst, Bolly & Boutet, 2016) - 2 Noitom Perception Neuron body straps, each equipped with 25 IMU (Inertial Measurement Units), recorded with Axis Neuron software - 1 Kinect for Windows v2 (also known as Kinect for Xbox One) depth sensor centered on the interviewee, recorded with Brekel Pro Body v2. Thus, for each participant, our 5 timed data flows are: 2 video streams at 25 fps – synchronised, visualised and annotated in the ELAN software (Sloetjes & Seibert, 2016) –, and BioVision Hierarchy (BVH) files (see Meredith & Maddock, 2001). These BVH files are visualised in Motion Inspector, and the following descriptors are computed in Matlab for the three age groups in our sample: the global quantity of ...
