Simulation for training, as we know it today, began back in 1934 when Ed Link sold his “Pilot Maker” to the (USA) Army Air Corps to help train people to fly the first airplanes. But simulation for training people to operate heavy equipment in forestry, construction, mining, and material handling, continues to be something “new”, and so this blog is meant to help you learn more.

The fact is, after over 20 years as Simlog’s President (and Founder), and 15 years of work before that in engineering and university research, I’ve developed a unique perspective on what’s really important (and what’s not), and so I hope that you’ll find these entries informative.

For example, the various parts of the simulated lift truck should have the right shapes and sizes, in the right proportions. And when the (simulated) sun shines, it should cast (simulated) shadows that look like real ones. (...)

Time was, it took real strength to operate the controls in the cabs of heavy equipment. But with everything computerized these days, anyone with two hands and two feet (and eyes and ears) can do just fine, male or female, big or small.

There is increasing interest in using “Virtual Reality” (VR) Headsets such as Meta’s “Quest” for video gaming [1] and simulator-based training. The idea is simple: when you turn your head, movement is detected by “head-tracking” electronics in the VR headset, and then what you see on the two small displays (...)

A recent article in Bloomberg Businessweek [1] noted that employers are increasingly working with their local high schools to develop new programs that combine classroom learning with on-the-job training. The objective: grow your own skilled workers. “With almost two openings for every person looking for work, US companies are increasingly (...)
