You can find the center point of the target in screen space using the method described in this thread: http://ar.qualcomm.at/node/2000570

If you want to render the text in 3D on the target you'll need to use OpenGL. Unfortunately the OpenGL API doesn't support text directly, so you'll have a bit of work to do. See this thread for some ideas: http://stackoverflow.com/questions/1339136/draw-text-in-opengl-es-android
