Keynote Speaker
Jeff Higginbotham PhD
Director of the Communication and Assistive Device Lab, University at Buffalo, Buffalo, NY, USA
- Looking at AAC Through Time and Interaction: Jeff Higginbotham discusses a simple but powerful idea: communication technologies don’t just help people say things—they shape how quickly, smoothly, and naturally people can take part in everyday conversation. He asks, if conversation is central to being human, how have AAC tools evolved to support better real-time connection with partners—and what priorities should guide what comes next?
About Jeff Higginbotham PhD
I earned my PhD in Comparative Studies of Human Social Interaction from the University of Wisconsin–Madison in 1985. Since then, I have spent most of my career at the University at Buffalo studying the conversations of people who use communication aids, with the goal of developing more socially responsive communication technologies. In recent years, my work has focused on the use of artificial intelligence in augmentative and alternative communication (AAC) and its potential to better support real-time interaction.
