Is there a way to continue operation during input()?

So what I'm essentially trying to do is, I have a switch statement in a while loop. Using an input() function, MATLAB will take the user input and put it through the switch cases. Pretty simple. But now, I want to modify it such that if MATLAB does not receive a command during input() for X number of seconds, it will continue the code, instead of waiting for user input. Ineveitably, it will go to the default switch case becuase a null input will not match any of the cases, and then the while loop will take me back to input(). So is there a way to "unpause" the code during input() automatically without me having to press ENTER?

The below two mostly rely on Psychtoolbox

Something like
%% a script named cssm.m
while true
user_input = waitinput( 'prompt: ', 5, 's' );
if isnan( user_input )
user_input = 'default';
disp(' ')
end
switch user_input
case 'default'
disp('default')
case 'poi'
disp('poi')
case 'abc'
disp('abc')
case 'quit'
disp('good bye')
break
otherwise
error('failure')
end
end
And a little test
>> cssm
prompt:
default
prompt:
default
prompt: poi
poi
prompt:
default
prompt: quit
good bye
