I could not find the information online. There are many laser Rangefinder that comes with Bluetooth and an application. But I wonder if those device are/could be seen like a regular keyboard. I mean getting a distance will send it to the smartphone as if the user had typed it (what most barcode scanner does).
Is it the most common behavior ? Does only some of them do that? Or not any?
I'm working on a webapp and getting dimensions from real world directly into the app would be nice.
Please answer only if you have seen one working. Thx.
