Headband with sensors ~

Could you make a headband with sensors and vibrating motors like in the ditto that could alert you to things that you may not sentence. Especially behind you.

Paint gun truck ~

Like an ice cream truck it could drive through the neighborhood and the kids and adults could come out with their paint guns and shoot at the truck with their paint pellets.

It could be a subscription thing where you get people to sign up online for a specific day to drive by their house in a certain hour. That way they don't know exactly when it's gonna happen but they can be ready.

AR info from badge ~

Why not make a AR augmented reality glasses that when you go in a store your devices read chips or network transmissions from an employee's badge and they put some sort of identifier over the head of that employee with their name and position in the store. And even when dealing with somebody at a register when you look at their face you see the store logo with the face, or the fees covered with the store logo.

That way you would know more than ever that you are dealing with the store and not the individual.

I could see where this could change the dynamic of interactions in a store. Instead of getting mad at a person because of their attitude and their take you would be focused on how the store is treating you. And the employee would know that they are being seen as the store and they would be reminded to do their best to represent the store in the best light.

AI sharing memories ~

Have in artificial intelligence that goes through all of the history and video and pictures of polio, the Spanish flu, and different pandemics.

And then have them go through a bunch of diaries from that time..

And then when you ask questions have it preface it's answers with phrases like "Well, I remember it being like this" or "from what I saw it was like this".

They could make a lot more personal and make it seem a lot more real.
