2 channel remote to HID Keyboard USB input

Hello,

I am looking for some project guidance.
What do I want to build?
A 2 button remote that gives HID keyboard input to a PC trough USB.

For example.
If I press button 1 on the remote, in a text field on the PC the text 'OK' appears, followed by an 'enter'.
If I press button 2 on the remote, in a text field on the PC the text 'NOK' appears, followed by an 'enter'

See the picture attached for a idea of the project.
The question I have: What Hardware do I need?

offcourse an Arduino Uno, but wich type op remote / receiver?
Also how do I code the input of a digital input to be translated to a string for HID input to en PC?

kind regards,
Jan

You need an Arduino that supports HID functionality; an Uno is not one of them (unless you hack it).

Arduino Leonardo. Micro, SAM based boards
SparkFun ProMicro
Teensy

For the remote I would get one that comes with the complementary receiver. Probably something like shown on this page. You must take a decision of you want IR or RF communication.
