5 Sketches of Class room scene required

Scene 1 (total 3 sketches) Standard class room scene, as seen from the vantage point of a sitting student. The teacher is teaching through 'smart class room'. There is a big screen (along with projector) facing the students, and the teacher is partially facing the screen and partially the sitting students. Let the screen be mounted in right half of the wall facing the students. There is a teacher's desk in the middle. The teacher is standing sideways, next to the teacher's desk, such that to his left diagonal is the screen (and possibly the black board), teacher's desk right in front (with a chess board sized board, having random QR code kind of drawing, on top of the table), and student's on the entire right hand of the teacher. The teacher would be holding a 3D mouse (something midway between a gun and kitchen gas lighter) in his hand and pointing to an invisible object on the board. Three variants of teacher may be required - (a) Teacher looking at the board and wearing a google cardboard virtual reality box, or (b) Teacher looking at the screen and not wearing anything, but having a small camera pinned at his shirt button, with wire connected to his smart phone kept in his pocket, or (3) The teacher holding the smart phone in one hand while trying to look at the 'chess board' through the phone. The holding and pointing of 3D mouse remains the same in all the three cases. All the equipments mentioned above, namely - screen, 3D mouse, VR box, button camera, connecting wire, and smartphone should be schematically visible and are to be numbered 1, 2, 3, etc., just as different parts are illustrated in a user manual. Scene 2 (2 sketches) A school lab kind of set up, seen from a bird's eye, with a teacher standing next to (say) a round table, with students gathered around the table. Again the teacher has a board on the table, and pointing to an invisible 3D object hovering over the board. The teacher can function in two modes - (a) Seeing the invisible object through a mobile phone held in the other hand, or (b) Wearing the same smart phone in a VR box and seeing at the board through it. All the students, are looking at the invisible object on the board through a mobile phone held in each person's hand. Some of them are wearing the same in their VR box. We can also show some students to be holding 3D mouse of their own, thereby depicting that multiple person can operate on the invisible object simultaneously.
