Carolane Mascle, « Le livre tactile illustré : influence de la technique d'illustration sur la reconnaissance des images par des personnes voyantes et non-voyantes », HAL-SHS : sciences de l'éducation, ID : 10670/1.53fo2z
From an early age, illustrated books play a role in the development of written awareness (Yaden, Rowe, MacGillivray, 19991999). However, children with visual impairments do not have access to illustrated books like sighted children do. Some children may enter school without ever having access to any book (Claudet, 20142014). In addition, there is no guarantee that tactile images can be easily recognized.In this thesis, we studied the influence of different illustration techniques on the recognition of tactile pictures. Based on the state of the art, we proposed to simplify the shape of tactile pictures. Indeed, simplification can facilitate the process of creating images. Moreover, it can limit the amount of exploration movements and the work of mental integration required in order to make the pictures more accessible to touch. In blind children we have observed that patches of textures are recognized as well and learned faster than pictures with textures frequently used in tactile books (recognition rate: 87.8%, 95% CI [81.3, .92.2] ). We also assessed the relevance of using new technologies such as retractable pin tablets (Zarate, Gu dozhnik, Ruch, Shea, 20172017) to display dotted pictograms. While the use of line pictograms seems to be a good illustration technique (recognition rate in blind children: 89.7, 95% CI [78.4, 94.8]), recognizing dotted pictograms can be more difficult. We have therefore proposed recommendations for the design of dotted pictograms that can be displayed on retractable pin tablets. Our studies focus on sighted and blind adults and children. We were able to provide additional data to better understand the factors involved in haptic perception such as visual status, haptic expertise, age (children or adults) or the size of the finger. In general, the studies carried out in this thesis provide a better understanding of the processes involved
