• On the Evaluation of Novel Sonification Techniques for Non-Visual Shape Exploration

  Sergio Mascetti, Andrea Gerino, Cristian Bernareggi, Lorenzo Picinali · 2017 · ACM Transactions on Accessible Computing (TACCESS)

  This paper proposes and evaluates six novel sonification techniques for enabling blind and visually impaired users to explore and recognize shapes on touchscreen devices, comparing them against two existing techniques from the literature. The motivation is that graphical…

• Producing Accessible Statistics Diagrams in R

  Donal Fitzpatrick, A. Jonathan R. Godfrey, Volker Sorge · 2017 · Proceedings of the 14th International Web for All Conference (W4A)

  This paper presents a system for making statistical diagrams accessible to blind users by generating semantically enriched SVG graphics from the R statistical computing environment. The core problem is that statistical graphics — bar charts, histograms, box plots, scatter plots,…

• Multimodal Perception of Histological Images for Persons Who Are Blind or Visually Impaired

  Ting Zhang, Bradley S. Duerstock, Juan P. Wachs · 2017 · ACM Transactions on Accessible Computing

  This research addresses a critical barrier preventing blind or visually impaired (BVI) students and scientists from participating in STEM laboratory work: the inability to perceive real-time visual scientific data from instruments like light microscopes. While tactile graphics…
