"Invisible" dog fences are Baked and WKTE;this takes the concept a little further, and will be particularly useful to those with wayward pets.
The device consists of a pair of lightweight goggles that the dog wears, connected to a backpack, which contains an image generation processor and a data library, a battery, and a GPS unit.
The owner sets up one or more "geofences"; as the dog approaches the geofence, the system generates a virtual reality image of a very deep trench - like a haha - with a very high, blank wall on the other side. The image is sufficiently real that the dog will not proceed any further.
The DeLuxe version has an option to generate imaging such that the dog percieves itself to be between very high fences, which route it back to the owner's location, controlled by an app on their cellular phone handset. They can also pick up the view from a webcam on the pet's collar.
It is a relatively simple task for the owner to set up "safety" fences along the kerbs of all the roads in their home area.
A version for cats is being developed which works in the same way, except that on a coded command sent by the Borg Collective the cat hears (and sees) a pack of slavering dogs pursuing it, and busy major highways appear as nothing more than an area of open parkland ...-- 8th of 7, Jul 21 2019 Virtual fetch from the person's perspective. https://www.youtube...watch?v=AZpfvqjMEIANot the most popular video on Youtube. 12 views.

Or a much bigger dog. Dogs would probably need olfactory augmentation-- theircompetitor, Jul 21 2019 I don't know, ever try to put a hat on a dog? Goggles would be the next step up in canine headgear securing challenges.-- doctorremulac3, Jul 21 2019 Dogs who ride on motorbikes (usually in a special rear carrier) often wear goggles. There are numerous images if you care to search.-- 8th of 7, Jul 21 2019 Fair enough, but you're rewarding them with a nice ride.
That being said, I'm sure the problem could be worked out even if the solution involved duct tape.
On the other hand, maybe you get them to like it by throwing some games in there like virtual fetch.
OK, criticism cheerfully withdrawn contingent on the addition of the incentivizing virtual fetch thing. [+]-- doctorremulac3, Jul 21 2019 You know, fairly easy to try out the virtual fetch concept. Show this video to a dog and see what it does. (link)-- doctorremulac3, Jul 21 2019 random, halfbakery
