In This Issue

As computer technology continues to make inroads into our lives, the man/machine interface assumes greater importance in the total system design. Human-factors engineering, our theme this month, is the discipline concerned with the need for friendly computers. Our cover, photographed by Paul Avis, features a new, user-friendly product, the IXO Telecomputing System. For a detailed description of this hand-held terminal see Chris Morgan's editorial.

To help you make your systems user-friendly, we present "A Human-Factors Style Guide for Program Design" by Henry Simpson and "Designing the Star User Interface" by Dr. David Canfield Smith, Charles Irby, Ralph Kimball, Bill Verplank and Eric Harslem. In "A Human-Factors Case Study Based on the IBM Personal Computer," Robert G. Cooper Jr., Paul Thain Marston, John Durrett, and Theron Stimmel discuss the Personal Computer from a human-factors perspective. Steve Ciarcia demonstrates how to use infrared systems, William Barden Jr. presents a collection of projects for the TRS-80 Color Computer, Gregg Williams treats us to a sneak preview of Epson's new portable computer, and Bob Katz reviews the Hewlett-Packard Interface Loop.
