Note: This is a VR-based experiment; in the simulation, you can learn from scratch how to download the APK and use VR, while the Procedure section explains the actual lab experiment steps as performed in the Virtual Reality (VR) Lab.

Actual vs Virtual Reality Lab Procedure

1. Setup & Transportation :

Actual (Physical Microscope)
Carry the microscope with both hands and place it gently on the lab bench. Plug in the light source.

Virtual Reality (VR) Lab Procedure
The user appears in the virtual lab with the microscope ready on the bench. Using the VR controller, they can click each labeled part (e.g., Nose Piece, Stage, Fine Adjustment) to view its description.

2. Slide Placement :

Actual (Physical Microscope)
Lower the mechanical stage, place the prepared slide, and secure it with the stage clips.

Virtual Reality (VR) Lab Procedure
The user uses the VR controller’s grip to grab and place the slide on the virtual stage, where it snaps correctly into position.

3. Initial Focus (Low Power) :

Actual (Physical Microscope)
Rotate the nose piece to position the Low Power (10x) objective. Use the Coarse Focus Knob to bring the specimen into rough focus.

Virtual Reality (VR) Lab Procedure
The user points at the virtual Coarse Focus Knob and rotates it using a grip/trigger gesture, observing the stage move and the image come into focus.

---

4. High Power Focus :

Actual (Physical Microscope)
Without using the Coarse Focus Knob, rotate to the High Power (40x) objective and use the Fine Focus Knob for clarity.

Virtual Reality (VR) Lab Procedure
The user rotates the virtual nose piece and adjusts the Fine Focus Knob to sharpen the image in the virtual eyepiece.

5. Visualizing the Light Path :

Actual (Physical Microscope)
(Cannot be performed — the concept is unobservable physically.)

Virtual Reality (VR) Lab Procedure
The user clicks the “See Light Path” button to view a red light ray traveling from the light source, through the specimen, and into the eyepiece.

---

6. Illumination Adjustment :

Actual (Physical Microscope)
Adjust the Iris Diaphragm or rheostat to improve image contrast and brightness.

Virtual Reality (VR) Lab Procedure
The user interacts with the virtual intensity knob or slider to adjust light levels and observe brightness changes on the specimen.
