Loading data in the background?

I have a set of code that does the following:
  1. Load a set of data
  2. Display the data
  3. Wait for the operator to make a judgement on the data.
  4. Record the user's judgement
  5. Repeat steps 1-4 for the next set of data (hundreds of datasets).
I have found that it takes about 5-10 seconds to load each dataset, and about 10-15 seconds for the user to make the judgement call. Unfortunately, the user is sitting idle while waiting for the data to load between sets.
Does anyone know how to load a .mat file in the background so that the next dataset can be loading while the user is in the process of making his/her judgement?
Thanks in advance.

AFAIK: it's in the Parallel Toolbox

TIMER objects seem to run in an own thread. Therefore you could load the data in a TIMER callback. But as usual for parallel programming, you have to be smart to avoid collisions between read and write access to the data.

I had the same thing happen when using the timer.
