Job aids, digital videos, audio, Learning, mLearning, augmented reality, QR-code triggered learning, desktop toys, ILT, virtual learning, gamification, mostly. I've developed training in each of those modes and enjoy it. My extra-curricular project is the development of a system that verbally delivers step-by-step directions on demand to a wireless headphone, then reports the time used to complete each step. When that's finished, I'd likely use it to train the staff, too.
