I'm looking for a small touchscreen that I can strap onto my wrist like a smartwatch. I simply want to send text (maybe even small images) to it via Bluetooth. I'd like to be able to update the display about 2 times per second.
And I want the Arduino to receive very simply touch input.
Instead of a tochscreen it could also just have 2 buttons or more...
Does something like this exist? Or does anyone of you know a very cheap smartwatch that could be used for this?
I'd like to have around 6 hours screen-on time if possible. I wouldn't really care if it is a bit bulky.
Design also doesn't matter too much. Something like this would do http://www.aliexpress.com/item/SainSmart-New-Electronic-Crystal-Table-Watches-DIY-Kit-for-SCM-LED-Watch-Digital-Watches-for-Arduino/32557520171.html
But it needs a lipo battery, a bluetooth interface and a proper screen.
Edit:
Has anyone experience remote controlling something like this? www.aliexpress.com/item/Bluetooth-Smartwatch-U8-U-Smart-Watch-for-iPhone-6-6-Plus-5S-Samsung-S6-Note-4/32494080470.html
