During my time at Strictly Business Computer Systems, we developed a few mobile games for Heritage Farm Museum & Village where attendees would categorize various items by whichever simple 6 machines they were.
Another project we helped work on where the attendees would walk around with a QR code scanner and they had to scan items that would have helped them survive as a pioneer.
We wanted to have a technological incentive for people to come to the museum, have activities that would engage children in learning about history and science.
