In relation to the projection vs LCD, the advantages of LCD is that you can build a thinner/smaller “box"/setup since you don’t need the space for the projector to get the size intended.
Regarding the optic sensing vs frame overlay, with optic sensing you can get fiducials/object recognition/finger recognition, depending on the method you choose.
Finally, the frame overlay gives you a good finger tracking and it is the easiest of the three options to setup. However, you won’t be able to recognize fiducials or objects
