Answer
Although your intentions were good, you were trying to give them a private place to sleep, without meaning to you have provided them with a place to hide from the world.  And they are taking advantage of that.

Remove the houses for awhile. They need to get used to their surroundings, the smells, the sounds and the people. Handle them as much as you can so they learn that people are wonderful things. Once they've become acclimated to their surroundings you can put the houses back in. The idea is to give them no choice about hiding when people come near them.

Every pig will do this, they used their little houses as a hidey hole and refuse to come out except to eat and drink. Removing their means of escape forces them to get comfortable in the open.  It won't take long, but I would keep the houses out for about 3 or 4 weeks.  

Each time you approach them bring a piece of carrot or lettuce so they begin to think of you as the 'food person' and will be excited to see you. It doesn't take long, it just takes a bit of patience.

Please let me know how things go, and if there's anything else I can help you with don't hesitate to write me.
