However after studied these papers I still found them confusing and wasn't sure if this is relevant to my research and if these papers conclude that emotional detection is possible.

This is the best and clearest example which shows the mood detection technology has been available since 2006 and has been used by NASA. Exmocare  is designing the second model of this product which is said to be smaller, smarter, blue tooth enabled version. 

The BT2 is going to be produced in larger quantities and passed through the elderly care system which shows that the product is going to be accessible soon.

The relevance of this is that it determines  whether the user has to input their emotional state or whether it can be detected automatically.
