I’ve an Amazon Alexa in my home connected to wifi enabled lightulbs so I can walk into, for instance, the master bedroom and say “Alexa, turn on the bedroom lamp” and it will send a message to the lamp to turn it on (or off). It’ll even turn it up or down or, with the right bulb, change the colour and therefore mood of the room with a voice command.
There is a problem with voice activated devices however which is that you need to learn the device names – and more than that, the syntax of the device name. So, “Alexa turn on the lamp” won’t work and indeed, if there’s another lamp into an adjacent room that you told Alexa was called ‘lamp’ then it will turn that one on. If you had a wifi connected lamp in every room you’d then need to teach Alexa, and everyone in the family that the this lamp is called “master bedroom lamp”, that one is called “back bedroom lamp” etc. etc.
You see the problem, the more connected home products you have the more you need to teach Alexa, yourself and other members of the family the names and syntax or each device.
Brilliant idea #360 is a ring (possibly a bracelet until the tech is miniturised enough) that can tell where you are pointing so you can say “Alexa, turn on (or off) and it will know what device you are pointing at. There’s likeley to be some limitations, at least to start with, so it will know the room you are in and that you are, for instance, pointing upwards (at the ceiling light) or which corner of the room then it will turn on the nearest device.
