Rob St. Amant
I'm an associate professor in the Department of Computer Science at North Carolina State University. My CV is online. I study topics in human-computer interaction and cognitive modeling. I've also written a popular science book called Computing for Ordinary Mortals (Oxford University Press, 2012). From the catalog description:
Computing isn't only (or even mostly) about hardware and software; it's also about the ideas behind the technology. In Computing for Ordinary Mortals, computer scientist Robert St. Amant explains this "really interesting part" of computing, introducing basic computing concepts and strategies in a way that readers without a technical background can understand and appreciate. Each of the chapters illustrates ideas from a different area of computing, and together they provide important insights into what drives the field as a whole. St. Amant starts off with an overview of basic concepts as well as a brief history of the earliest computers, and then he traces two different threads through the fabric of computing...

Research in my lab can be summarized as targeting models of interaction, drawing on concepts in artificial intelligence, human-computer interaction, and cognitive science. (Our results have appeared in HCI, AI, and even animal behavior publications.) Some of the pictures on this page are linked to 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 both existing and novel cognitive architectures; we are also exploring brain computer interfaces. Students: Sina Bahram, Arpan Chakraborty, KyungWha Hong, Shea McIntee, 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. Students: Sina Bahram, Pat Cash, Arpan Chakraborty, Jeff Wilson.
Tool-based user interfaces
Tool use is a hallmark of intelligent behavior, but current interactive systems do not fully exploit our abilities. Projects in my lab include Google Glass apps and a tool-based user interface for large touch surfaces; we have even done research on animal tool use. 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. Students: Sina Bahram, Arpan Chakraborty, Prairie Rose Goodwin, Ryan Gross, KyungWha Hong, Shea McIntee.
Software: CAVIAR (Computer-vision Assisted Vibrotactile Interface for Accessible Reaching) is available for download. I maintain a set of AI planning systems written in Common Lisp intended for classroom use. (People may find the AI Planning Resources page useful too.) Two older systems may be of historical interest: G2A translates high-level procedural GOMSL models into detailed cognitive ACT-R 4 models. SegMan is a perceptual substrate that uses simple image processing techniques to "see" the Microsoft Windows graphical user interface.
