Jim Joula is a cognitive psych professor/researcher and is one of the early pioneers in HCI research. He published like 40+ papers on the topic in the course of first 10 years of personal computing. Jim just headed back to Philips in Europe to do some more research early this year. Philips is not afraid to invest aggressively in R&D and are becoming more and more user/customer focused. I would expect to see more great things from them in coming years.
