• μGraph: Haptic Exploration and Editing of 3D Chemical Diagrams

  Cristian Bernareggi, Dragan Ahmetovic, Sergio Mascetti · 2019 · Proceedings of the 21st International ACM SIGACCESS Conference on Computers and Accessibility (ASSETS 2019)

  This paper presents μGraph (Multimodal Graph), a system that combines haptic force feedback and speech to enable people who are blind or visually impaired (VIB) to explore and edit three-dimensional structural chemical formulae. Chemical diagrams represent molecular structures…
