An app that uses a camera mounted on your glasses /
lapel to spot gum on the footpath / sidewalk.
It then uses your smartphone to compare the image to
a database of known gum spots in that area.
If it identifies a new gum spot in your likely footfall
zone it sends a signal to a gyroscopic
device in the
heel of your shoe to move your foot slightly so as to
avoid stepping in the masticated mess.
