The idea for MARK emerged when I moved into a new house and struggled with tasks like hanging picture frames and installing shelves in perfect alignment. With just a tape measure, manually marking the walls at different heights felt tedious and inefficient. During the fourth week of my XR Bootcamp, I was tasked with choosing a solo project idea to prototype for my portfolio. Out of five concepts I brainstormed, my mentor selected WallAlign, recognizing its potential to solve a common real-world problem.

During the bootcamp, I developed the app's two key features, and after the program ended, I was motivated to expand its functionality further. Testing the app with friends—especially artists and carpenters—yielded overwhelmingly positive feedback, confirming its practical utility and inspiring further development.

Precise Alignment Assistance : Enables users to project and mark precise points for hanging items or creating level surfaces.

Line Drawing Tools : Users can draw, adjust, and mirror lines on walls, ensuring symmetry and alignment.

Dot Projection : Instantly place and adjust dots for marking positions on walls.

User-Friendly Menu : The menu UX was thoughtfully designed by analyzing the natural resting position of the human hand, optimizing for minimal movement and comfortable access angles.

Meta SDK Proficiency : Prior to this project, I had no experience with the Meta SDK or developing for Mixed Reality. I quickly adapted by completing the XR Bootcamp’s Udemy course, "Build Your MR Game & Publish it on Meta's Horizon Store," which enabled me to confidently work on this prototype.

Line Renderer Mastery : Overcame challenges with local and global coordinates in line rendering, gaining in-depth knowledge about Unity's line renderer.

Menu UX Design : Designed a menu optimized for comfort by analyzing the natural resting position of the hand and minimizing movement and angle requirements.

Canvas Layering : Resolved complex issues with managing canvas layers and UI element hierarchies, further improving my Unity UI skills.

AI Image Search Integration: Allow users to project AI-generated images onto walls for creative tracing, enhancing artistic projects.

Extended Object Detection: Utilize the camera API to detect object planes like wood, paper, and other materials, expanding functionality beyond walls.

Tool Expansion Based on Feedback: Incorporate additional tools and features based on user feedback from artists and carpenters to better suit their needs.

Shared Collaboration: Implement shared experiences, enabling multiple users to collaborate in real-time on projects for enhanced interactivity and usability.

A Virtual Reality Educational Prototype As part of the second 2-week MVP sprint during XR Bootcamp, my team and I developed Labify VR, an innovative VR app designed to make learning cell biology engaging and interactive. Labify VR immerses users in a fully virtual world where they can explore various types of cells, navigate their parts, and learn about their functions through interactive labeling, gamified quizzes, and a welcoming 3D guide. This experience leverages the spatial and immersive capabilities of VR to provide a deeper understanding of cell biology.

Teacher Talking Head : A 3D guide helps users understand the objectives and steps.

Interactive Learning :

   - Explore different types of cells, including plant cells, animal cells, bacteria cells, and blood cells.

       - Interact with organelles (e.g., plant cell organelles) by selecting different parts to learn their names and functions.

Video & Audio Learning : Educational videos with audio explain key concepts.

Gamified Quiz : Engages users by familiarizing them with organelles and their functions.

User-Friendly Design : Includes a main menu and tutorial for easy navigation.

The MVP was brought to life through the collaborative efforts of:

Me :

     - Implemented grabbable organelles for an interactive experience.

     - Developed socket interactions with haptics for tactile feedback.

     - Worked on the quiz logic to create engaging gamified assessments.
