Virtual Med Trainer

Maya . Unity | Developed for Oculus Quest 2 | This project was finalized in September 2020

This Virtual Reality project aimed to create a realistic and immersive simulation of a surgery room for laparoscopic procedures. Laparoscopic surgery is a minimally invasive technique that uses small incisions and specialized instruments to perform various operations inside the body. It requires a high level of skill and precision, as well as a good understanding of the anatomy and physiology of the organs involved. Therefore, it is essential to provide adequate training and education for laparoscopic surgery residents, medical students, and healthcare professionals who want to learn or improve this technique.

The main goal of this Virtual Reality project was to build a virtual surgery room to train laparoscopic surgery residents, medical students, and healthcare professionals and to build a virtual surgery room that resembles a real one as much as possible.

The secondary goal of our project was to provide some educational content and feedback for the user. We designed some scenarios that simulate different laparoscopic procedures. Each scenario consists of several steps that guide the user through the procedure using voice instructions and visual cues. The user can follow the steps using the virtual instruments and performing the required actions on the virtual fetus. At the end of each scenario, the user can receive some feedback on their performance based on some criteria such as accuracy, speed, errors, etc.

We (Ali Taheri and I) chose Unity because it is widely used in the VR industry and has a large and active community of developers and users who provide support and feedback. I used 3D models, textures, sounds, and lighting to create a realistic environment that includes various elements such as surgical tables, monitors, lamps, instruments, a fetus, etc. Ali also implemented some interactive features that allow the user to manipulate some objects in the scene, such as opening drawers, picking up instruments, adjusting the camera angle, etc.

The target platform for our project was Oculus Quest 2, a standalone VR headset that does not require a PC or a smartphone to run. We chose Oculus Quest 2 because it is affordable, portable, easy to use, and offers a high-quality VR experience.

Due to some problems on the part of the client, this project remained unfinished.

By manually reducing the level of detail in the 3D models we bought from Evermotion, I have successfully optimized the models for our specific needs. This will not only enhance the overall performance of the models but also save us valuable time and resources.

Retopologized 3D model of a fetus that was created in zBrush, I suppose, to get it better suited to use in Unity.
