Debugging Geo-Fence technologies with schoolchildren in a 19th century schoolhouse

On Wednesday May 7th, RIT MS HCI and Allendale Columbia School students and faculty ran our mobile pilot test at Genesee Country Village Museum. As pilot tests go, we ran into a few bugs. In particular, we run into bugs at geo-fences (a geo fence is a GPS coordinate with a mathematical virtual radius drawn around a latitude and longitude). When the physical visitor collides with this digital artifact, we deliver contextually relevant digital content to the visitor.

We were not sure why our video content wasn’t playing correctly at the geo-located schoolhouse. We took the opportunity to use the 19th century schoolhouse as a schoolhouse. The Allendale Columbia students sat with their 19th century tablets (hand held chalk boards) while RIT faculty began to explain the notion of the Geo-Fences and why we may be running into problems. After about fifteen minutes we came up with a number of reasons why our video content wasn’t playing with our hand-held chalk boards. Some potential bugs could be related to:

  • 4G video streaming issues
  • distance from 4G towers
  • AS servers may have been slower
  • GPS coordinate was off 15-20 feet
  • problems with the iOS code
  • Geo-Fence was too small, etc
  • Video mp4 format could be corrupted,

After collecting these possibilities we brought them to our development team at RIT the next day. Out of all the potential problems it was “problems with the iOS code”. The development teams fixed the bugs to have a successful usability test on May 14th with school students from Syracuse, NY.
