Dynamic Text overlay on live camera feed

Please can anyone suggest if they have attempted to have camera on and dynamic text overlaying done depending on what is identified in the view.

Eg. point a camera to the fruit and i should be able to identify the fruit and display text over the camera feed. The moment i move to next object it should ask me if ii want to save this or discard to move to new object.
