    Keyboard Input acceptance delay

    Hello, I am a graduate student and for one of our experiments we would like to make it so we can control the number of keyboard inputs a person can do at a time.

    So for example they will be typing into a word document and we want to make it so that the program will only accept inputs after a certain amount of time has passed(say.37 seconds). So they hit one key, then any further key presses will not be recorded by the computer until a certain amount of time has passed.

    Is there any advice or products that you guys have or can recommend that will allow us to do this? The simplest way I would think is something that prevents the computer from receiving signals from the keyboard for a preset amount of time. Any help would be appreciated, we have been trying to do this for awhile now with no success.

    Well, you could use something like the PS2 keyboard library to read a keyboard, and then USB keyboard interface to send the keystrokes to the PC, with your code doing stuff in-between.

    Sorry I am not a programmer, would it be difficult to code what I am trying to do if someone had basic knowledge of coding?
