Looking to create a wireless button for a windows 10 tablet.
The button needs to be programable/assignable to a keyboard button, wireless, as small/light as possible, and automatically connects to the tablet (similar to a wireless mouse).
The context for the idea;
I work as a surveyor, and my tablet is attached to a pole. I would like to attach a button on the pole so I can use the pole and the tablet with one hand. The button would only be required to hotkey z, which is the hotkey for storing a measurement.
Any ideas, suggestions, links, or existing products please let me know.
Thanks in advanced
