“…The range of these methods is vast, extending from auditory encoding techniques, such as textual descriptions conveyed through speech [91], [95]- [97], to sonification, the use of non-speech sounds [42], [91], [98]- [101]. Other methods involve advanced haptic feedback systems [87], [88], [102], and physicalization for tactile representations [69], [89], [103]- [107].…”

The increasing ubiquity of data in everyday life has elevated the importance of data literacy and accessible data representations, particularly for individuals with disabilities. While prior research predominantly focuses on the needs of the visually impaired, our survey aims to broaden this scope by investigating accessible data representations across a more inclusive spectrum of disabilities. After conducting a systematic review of 152 accessible data representation papers from ACM and IEEE databases, we found that roughly 78% of existing articles center on vision impairments. In this paper, we conduct a comprehensive review of the remaining 22% of papers focused on underrepresented disability communities. We developed categorical dimensions based on accessibility, visualization, and human-computer interaction to classify the papers. These dimensions include the community of focus, issues addressed, contribution type, study methods, participants, data type, visualization type, and data domain. Our work redefines accessible data representations by illustrating their application for disabilities beyond those related to vision. Building on our literature review, we identify and discuss opportunities for future research in accessible data representations.

“…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.…”

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.

Audio-tactile charts have the potential to improve data analysis with tactile charts for blind people. Enhancing tactile charts with audio feedback can replace Braille labels and provide more structured information than pure tactile graphics. Current approaches lack especially in support of gestural interaction to develop useful interaction concepts for audio-tactile charts. Many approaches make use of non-standard hardware or are less mobile. That is why we investigated digital pens and their capability to increase data analysis with tactile charts. We compared two digital pens, in particular, the TipToi pen and the Neo SmartPen M1. First, we evaluated the implementation and feasibility of five basic gestures. While the TipToi is not suitable to support rich touch gestures, the Neo SmartPen showed in a pilot study good support of single-tap, double-tap as well as hold and line gestures. On that basis, we implemented the first prototype to demonstrate the potential of digital pens to support data analysis tasks with audio-tactile scatterplots. Afterwards, we evaluated the prototype in a pilot study with one participant. The study shows high indications for the usefulness of the presented system. The usage of the digital pen can improve the readability of a tactile chart. Our system provides audio-feedback for given tactile scatterplots in an accessible and automatic way. As a result, blind users were able to produce and use audio-tactile charts on their own by using an Android application and the Neo SmartPen.
