Infield was a programming language for handheld computers in the 1990s.
It was originally developed by National Training Services, a Sydney-based company. They later shortened their name to NTS and later still, became Infield Solutions.
The language grew out of an idea from the Managing Director, Peter Mottlee. He wanted a Generic Capture Module that would run on a handheld device and which could be used by different users for different purposes. What was common was data entry and storage.
GCM was further genericised and became Infield.
The following are some screenshots from Infield back then.
This one is a sample screen showing just some of the things that were possible. It could also integrate with a GPS receiver and store geo-coding information along with information entered by the user. This was a pretty good trick at the time as GPS was still primarily a military system with negligible civilian use back then.
Infield software ran on a range of handhelds including, Symbol, Norand, Husky, and TouchPC.
