nightlight solution needed

I need a custom home lighting controller for my disabled father. What
I want it to do is control track lighting that will be used like a
nightlight. The operation is this:

When the circuit is triggered (either by a pressure mat by the bed or
an IR device to sense when my father has gotten out of bed) it will
turn the track lights on. The lights will stay on until my father
gets back into bed and then pushes a bedside switch to turn the lights
off. If my father gets back out of bed the circuit will trigger
again.
