Specifically I want to ask if there's any wireless glasses that can be used be as a computer monitor (display the same video you would see on your standard desktop PC monitor), and can't seem to find a "tech exchange". Did a lot of searching and googling. I must be blind.
I think the only site coming close to what you want is the Hardware Recommendations beta. The problem is that recommendation questions don't do well on most sites.
From their help:
Hardware Recommendations is a community-run website to help you find a specific product for your needs. That means you can ask for a recommendation for hardware to perform a specific task.
Please note that because of the subjective nature of recommending hardware, your question must meet the community quality guidelines - please read them before posting.
Questions that are about "what is the current" are often problematic in that all the answers get obsoleted every time there is a new current.
They also tend to get poor quality and near-spam answers.
There's a new kickstarter with wifi VR goggles but its been suspended pending investigation on brain cancer.
This type of answer isn't that helpful and often attracts low quality answers that as a side effect of how Stack Exchange work (based on timeless good answers) get archived for perpetuity.
You may find it more useful to go to one of the sites (not within SE) that is more forum like and transient with its questions and thus able to handle the temporal now better.
Furthermore, such questions often take the form of "list" questions. Consider the situation where such technology does exist.
I am looking for a thing where you tap it and letters appear on the screen. Kind of like a TV Typewriter.
You are looking for a Logitech keyboard.
You are looking for a Epic Bluetooth Virtual Keyboard.
I use a corded keyboard. Here's a link...
And so on. As there are countless of these products, this type of question really starts to fall apart become less and less useful to future readers. Especially as some of the products may have been discontinued.
