tScratch: Tangible Programming Environment Targeted for Students who are Blind or Visually Impaired
Introductory programming languages are overwhelmingly designed with sighted students in mind. Our goal is to expand and enhance scratch (https://scratch.mit.edu/), a block-based visual programming language and online community targeted primarily at children with Universal Design for Learning (UDL) concepts. The addition of tactile programming tiles, a specialized haptic coding grid, and an auditory interface will provide beginning programming instruction for students either as individual…
Tactile graphics use raised lines, textures, and elevations to provide individuals with visual impairments access to graphical materials through touch. Tactile graphics are particularly important for students in science, technology, engineering, and mathematics (STEM) fields, where educational content is often conveyed using diagrams and charts. However, providing a student who has a visual impairment with a tactile graphic does not automatically provide the student access to the graphic's educational content. Instead, the student may struggle to decipher subtle differences between textures or…

This project study the neural mechanisms of texture and motion based segmentation as basic inputs to object processing. This project used frequency-domain non-linear analysis of high-density EEG recordings in human infants. We also used fMRI-informed EEG source-imaging combined with psychophysics to study texture segmentation processing and the role of attention in normal adults and in adults with amblyopia.
