His research examines mobile and smartwatch interface development, with a focus on tracking and support software for people with disabilities. He’s also the father of three and is involved with them in sports and scouting in the Blacksburg VA area. In the 2011-2012 academic year, he was on sabbatical at the University of Colorado, Boulder, with his family. He used the sabbatical to write a book about claims and design rationale in HCI, using this blog to pilot ideas. He also used his time in Colorado to foster an enjoyment of walking, hiking, and bicycling. He continues to update this blog irregularly, balancing posts on work, family, travel, and fun. He also blogs about Technology on the Trail, his latest research (and personal) endeavor.
