Turning points in interaction with computers

The development of interfaces by which humans and computers interact has brought about some of the most significant turning points in computing in the last 38 years. The work on interfaces in programming languages, office automation, and human factors has enabled more and more people to interact effectively with computers, but there is more work to do. The IBM Systems Journal has published many papers that reflect results of work in this area, and readers can see a representative selection of those papers in this section of this issue.
