In this post, I list a set of products that I wish existed, I think are technically feasible with some R&D, have a potential market, and I will never create myself — though I am open to being added to the patent application.
Smarter Glasses - Smart glasses that change prescription focus based on gaze distance. I don’t mean progressive lenses that have different focal lengths as you move your eye up and down the lens, but glasses that could see where I was looking and focus on that. I have no idea how to make them, but I imagine AR glasses that have a small camera looking at my eyes are part of the solution.
Photocalorie - I take a picture or short movie of a meal, and an app uses AI to analyse its caloric and nutritional content. I may need to include something to scale the photo like a credit card.
Alibi - Link GPS tracking to calendar, an app that would track me and load that into a calendar so I know where I (or anyone else who shared) was at any given time, providing me a convincing alibi for any crimes I may be accused of committing.
House mapper - An app which you take video of your house and generates an accurate 3-D plan suitable for CAD etc.
Electric circuit mapper - Some convenient (and low cost, non-intrusive) way of mapping with high precision the location of all the electrical circuits in the walls of a building, and knowing which circuits were connected to each other and on the same circuit at the switchboard, without turning everything on and off again. This map could be turned into a 3D digital file. Ideally this could be done using existing sensors on smart phones, or a very small add on, possibly using Internet over home powerline wires.
StuffID - An app that uses the camera to take photos or video in high resolution, along with AI, of any parts of your house, and catalog all of the possessions therein (including books by their spine, toys, games, sporting equipment, clothes, records by their spine, tools, small appliances, etc.) for insurance purposes, warranty and instruction manual management (the product would be identified and the warranty and manuals linked in an online database) as well as easy sharing in a Distributed Physical Library, rent, sale or trade.
Distributed Physical Library - People are often willing to share in high trust communities. The nature of sharing increases trust. We have as a society far more copies of various things than we actually need because of the friction of borrowing or buying it on-demand. It would be better if you need a particular tool, book, record, clothing, art work, etc, you could easily coordinate with neighbours who have it to lend. This requires a database of all the stuff everyone has at their home, geolocated with high resolution GPS coordinates so you know where that stuff is within the home. It could even be connected with smart locks and cameras so you could go to your neighbours house, and collect the item without bothering them, just like Amazon delivers into your home.
Outraged - A single point of truth where I could figure out who was boycotting, cancelling, ostracising whom and why, and if such boycotts, cancellations, and ostracisms had ended. (There are small versions of this, but they don’t seem comprehensive or complete). (Obviously there would be at least two of these sites, as the first one would be cancelled by someone).
I am not actually going to build any of these, but someone should.
