“…In most studies, interactive tactile drawings were made by the research teams. Some tools automatically generate printable tactile maps with audio annotations [18,23,36], but it can be complicated to modify them. Authoring tools for interactive tactile media have been proposed, but only few systems were tested by end users (e.g.…”

Figure 1.A teacher draws interactive zones directly on a tactile map with his finger and records the associated audio-feedback using a microphone. Touching the same zone will later launch the recorded audio-feedback. ABSTRACTInteractive tactile graphics have shown a true potential for people with visual impairments, for instance for acquiring spatial knowledge. Until today, however, they are not well adopted in real-life settings (e.g. special education schools). One obstacle consists in the creation of these media, which requires specific skills, such as the use of vector-graphic software for drawing and inserting interactive zones, which is challenging for stakeholders (social workers, teachers, families of people with visual impairments, etc.). We explored how a Spatial Augmented Reality approach can enhance the creation of interactive tactile graphics by sighted users. We developed the system using a participatory design method. A user study showed that the augmented reality device allowed stakeholders (N=28) to create interactive tactile graphics more efficiently than with a regular vector-drawing software (baseline), independently of their technical background.

“…It appears that access to graphical information (maps, schemas, mathematical graphs, drawings, etc.) is impaired due to difficulties in popularizing tactile adaptations of visual graphics (which process is based on methods mastered by professionals called tactile documents makers [35]). Therefore, apart from special education centers, tactile graphics are rare and expensive.…”

Visual graphics are widely spread in digital media and are useful in many contexts of daily life. However, access to this type of graphical information remains a challenging task for people with visual impairments (VI). In this study, we designed and evaluated an on-hand vibrotactile interface that enables users with VI to explore digital graphics presented on tablets. We first conducted a set of exploratory tests with both people with VI and blindfolded (BF) people to investigate several design factors. We then conducted a comparative experiment to verify that on-hand vibrotactile cues (indicating direction and progression) can enhance the non-visual exploration of digital graphics. The results based on 12 participants with VI and 12 BF participants confirmed the usability of the technique and revealed that the visual status of the users does not impact graphics identification and comparison tasks.  CCS Concepts: • Human-centered computing → Accessibility; Empirical studies in accessibility; • Human-centered computing → Human computer interaction (HCI)

“…), car ce matériel doit être adapté sous forme tactile. Ce!e adaptation repose sur des méthodes de transcription maitrisées par des professionnels [33] et les graphiques produits ne peuvent pas être modifiés facilement [17], ce qui les rend relativement rares. Le manque de confrontation à des représentations graphiques peut alors porter a!einte à la capacité à conceptualiser et à apprendre à partir de données graphiques, ce qui a un impact sur l'éducation et la mobilité, et donc sur l'autonomie et la qualité de vie des personnes ayant une déficience visuelle.…”

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.
