I've always wanted to try this but is there a privacy implication? I guess it connects to an openstreetmaps account, which will then keep a public history of all the places you've been.
You can replicate that remotely. I've had days where 2-3 people joined a call to share something and then kept that call in the background for hours, chatting about random things while working.
The question is, is there a practical difference between lucid dreaming and dreaming about being lucid? I like to think it's the memory afterwards that counts.
I can bring my hands from the back of my body to the front (and the opposite) while holding them together. There might be a use for this if I ever get tied up.
But if you do see a normal keyboard and can type each letter isn't that the same as what autocorrect is doing now? If I type "spmrthjng" my keyboard already autocorrects to "something". If you only see the keyboard after it's guessed wrong then that would just be autocorrect with more steps.
Usually not and I always found it weird. In the rare occasion a smartphone appears in a dream it's always impossible to use, like nothing works correctly. I actually had a dream today where I was lost and Google Maps was giving some very bad instructions.
Strangely enough I don't think I've ever dreamt of a computer even though most of my day is spent in front of one.
