“…Ducasse et al [10] ont proposé une classification des dispositifs interactifs perme!ant de parcourir des graphiques numériques. Ils ont distingué les dispositifs hybrides, incluant des composants physiques et numériques [6,11], et les dispositifs uniquement numériques [1,4]. Une des conclusions de ce!e revue de la li!érature est que les graphiques uniquement numériques sont ne!ement plus faciles à manipuler et à afficher, mais souffrent de l'absence d'indices tactiles.…”

“…Concernant les modalités d'interaction utilisées, différents types de retour, par exemple auditifs [4], haptiques (y compris vibratoires) [25,31,32], ou multimodaux [14], ont été étudiés afin d'améliorer l'utilisabilité des graphiques numériques. Excepté [26] qui a utilisé des icônes tactiles dynamiques sous le doigt pour transme!re des informations directionnelles, aucune étude ne porte sur la présentation de la direction d'un segment numérique basée sur des indices vibrotactiles.…”

“…Ces dernières années, de nombreuses études ont montré qu'il était possible de perme!re aux PDV d'accéder aux informations graphiques numériques au moyen de techniques d'interaction haptiques et/ou sonores, ce qui permet de profiter des avantages des informations numériques (facilement modifiables [10] et interactives [4]). Parmi ces études, plusieurs travaux ont été menés pour concevoir des techniques d'interaction perme!ant de rendre les graphiques numériques accessibles [4], mais aussi pour étudier les stratégies utilisées pour explorer les graphiques physiques [5]. Les découvertes ont montré qu'il existe notamment des indices tactiles particulièrement importants lors de l'exploration de graphiques physiques.…”

Graphics are useful in many contexts of daily life (education, mobility, etc.) and spread widely in digital media. However, accessing to digital graphical information remains a challenging work to people with visual impairments. In this study, we were interested in the transmission of vibrotactile cues allowing users to explore digital graphics more easily and faster. We have designed a vibrotactile matrix fixed on the hand for presenting directional information. Two vibrotactile displays-Spatiotemporal Vibrotactile Pattern (SVP) and Apparent Tactile Motion (ATM)-were compared. A study with sixteen blindfolded participants examined the efficiency and user preferences of proposed interaction techniques and showed that the recognition accuracy with SVP is significantly better. Final study involving six participants with visual impairments confirmed the improvement of digital graphics exploration with vibrotactile directional cues.

“…For example, Kane et al [31] designed innovative interaction techniques called access overlays that enable VI users to locate a landmark on a map (edge projection), retrieve the name of the nearest landmark (neighborhood browsing) or initiate guided directions to nd a landmark. Other techniques involve, for example, the use of a virtual grid [1,78] or of tactile overlays [32,61]. The main advantage of digital maps is that they can be instantly refreshed and can even be used in mobility when displayed on a tablet.…”

The development of novel shape-changing or actuated tabletop tangible interfaces opens new perspectives for the design of physical and dynamic maps, especially for visually impaired (VI) users. Such maps would allow non-visual haptic exploration with advanced functions, such as panning and zooming. In this study, we designed an actuated tangible tabletop interface, called BotMap, allowing the exploration of geographic data through non-visual panning and zooming. In BotMap, small robots represent landmarks and move to their correct position whenever the map is refreshed. Users can interact with the robots to retrieve the names of the landmarks they represent. We designed two interfaces, named Keyboard and Sliders, which enable users to pan and zoom. Two evaluations were conducted with, respectively, ten blindfolded and eight VI participants. Results show that both interfaces were usable, with a slight advantage for the Keyboard interface in terms of navigation performance and map comprehension, and that, even when many panning and zooming operations were required, VI participants were able to understand the maps. Most participants managed to accurately reconstruct maps after exploration. Finally, we observed three VI people using the system and performing a classical task consisting in finding the more appropriate itinerary for a journey.

Digital Interactive Maps on touch surfaces are a convenient alternative to physical raised-line maps for users with visual impairments. To compensate for the absence of passive tactile information, they provide vibrotactile and auditory feedback. However, this feedback is ambiguous when using multiple fingers since users may not identify which finger triggered it. To address this issue, we explored the use of bilateral feedback, i.e. collocated with each hand, for twohanded map exploration. We first introduced a design space of feedback for twohanded interaction combining two dimensions: spatial location (unilateral vs. bilateral feedback) and similarity (same vs. different feedback). We implemented four techniques resulting from our design space, using one or two smartwatches worn on the wrist (unilateral vs. bilateral feedback respectively). A first study with fifteen blindfolded participants showed that bilateral feedback outperformed unilateral feedback and that feedback similarity has little influence on exploration performance. Then we did a second study with twelve users with visual impairments, which confirmed the advantage of two-handed vs. one-handed exploration, and of bilateral vs. unilateral feedback. The results also bring to light the impact of feedback on exploration strategies.
