Tobias Weinberg

I am a CS PhD Student at Matter of Tech Lab with Prof. Thijs Roumen at Cornell Tech, dedicated to advancing augmentative and alternative communication (AAC) technologies. My research centers on developing systems to seamlessly integrate non-informative speech such as humor, interjection words/sounds, reading poetry, etc., enhancing expressivity for individuals with speech and motor impairments.

Areas of interest: accessibility, AAC, expressive communication, LLMs, human-AI interaction, and HCI.

CAMeleon: Interactively Exploring Craft Workflows in CAD
Shuo Feng , Lavenda Yifan Shan , Xuening Wang , Ritik Batra, Tobias Weinberg, and Thijs Roumen
(pre-print)  

Designers of physical objects make assumptions on the material and fabrication workflow early in the design process. Recovering from bad assumptions is hard, because the design and resulting CAD model are locked-in to those assumptions. We present CAMeleon, a software tool to interactively explore fabrication workflows at any stage of the CAD process.
