Rob St. Amant
I'm an associate professor in the Department of Computer Science at North Carolina State University. My research can be summarized as targeting models of interaction, drawing on concepts in human-computer interaction, cognitive science, and artificial intelligence.
I've written a popular science book, Computing for Ordinary Mortals (Oxford University Press, 2012), and personal essays for Salon and the New York Times.

This is a brief summary of current research in my lab. Images for the different research areas are linked to representative videos.
Embodied cognitive models
In the intersection between computer science and psychology we find embodied cognitive models: computational simulations of human performance on specific tasks. Projects in my lab include modeling of vision, gesture, and interaction with mobile devices, based on existing and novel cognitive architectures; we are also exploring brain computer interfaces. Current students: Sina Bahram, Liang Dong, Huseyin Sencan.
Accessibility and intelligent user interfaces
Techniques from artificial intelligence and related areas have great promise for improving interactive systems. One project in my lab, TIKISI (Touch It, Key It, Speak It), helps blind users interact with graphical information such as maps; a past project, CAVIAR, uses a specialized wristband and computer vision algorithms running on a mobile phone to guide a blind person's hand toward specific objects. Other work focuses on magnifying interfaces for people with vision impairment and improving mobile recommender systems. Current students: Sina Bahram, Pat Cash, Jeff Wilson.
Tool-based user interfaces
Tool use is a hallmark of intelligent behavior, but current interactive systems do not fully exploit our abilities. A project called CAPTIVE began in the summer of 2013, in collaboration with Jae Yeol Lee at Chonnam National University, Korea. CAPTIVE is an augmented reality/tangible user interface system for dealing with 3D information: the user holds a physical cube, watching it through a display with a camera mounted on the back (a stereo configuration is in progress), and sees virtual objects that track the cube's movement. We have also built a tool-based user interface for managing documents on a large touch surface. Current students: Sina Bahram, Prairie Rose Goodwin.
