HOW TO PLAY
VisionHunt uses your device camera and YOLOv8 AI to detect real-world objects. Here's everything you need to know to start hunting.
STEP-BY-STEP GUIDE
Launch the Game
Open VisionHunt on your mobile device. Grant camera permissions when prompted — the game needs your camera to detect real-world objects.
Choose Your Difficulty
Select Easy (3 objects, 3 min), Medium (5 objects, 2 min), or Hard (8 objects, 90 sec). Harder modes give more points but require faster hunting!
Get Your Hunt List
The game generates a randomized list of everyday objects for you to find. These are common COCO dataset objects that YOLOv8 can detect.
Point & Detect
Point your camera at objects around you. YOLOv8 runs inference in real-time, drawing bounding boxes around detected objects with confidence scores.
Earn Points & Streaks
When a target object is detected with ≥70% confidence, it's marked as found. Higher confidence = more points. Find objects consecutively to build streaks for multipliers (×1.5 at 2, ×2 at 3+).
Complete the Hunt
Find all objects before the timer runs out! Completing the full list earns a completion bonus. Your final score is submitted to the global leaderboard.

TIPS & TRICKS
Good Lighting
YOLOv8 performs best in well-lit environments. Natural daylight or bright indoor lighting gives the highest confidence scores.
Proper Distance
Keep objects at a comfortable distance — not too close, not too far. About 1-3 meters works best for most objects.
Center the Object
Try to center the target object in your camera frame. The model detects objects across the full frame but centered objects tend to score higher.
Plan Your Route
Before starting, think about where you might find the objects on your list. A good plan saves precious seconds.
Build Streaks
Find objects in quick succession to build your streak multiplier. A ×2 multiplier doubles all your points!
Speed Matters
Finishing the hunt quickly earns a speed bonus. But don't rush so much that you miss objects — accuracy matters too.
THE TECHNOLOGY
VisionHunt is a capstone project exploring real-time computer vision in mobile gaming
YOLOv8 Model
You Only Look Once (YOLO) is a state-of-the-art, real-time object detection algorithm. YOLOv8 by Ultralytics processes images in a single forward pass, making it fast enough for real-time mobile inference. It can detect 80 object categories from the COCO dataset with high accuracy.
How Detection Works
Each camera frame is passed through the YOLOv8 neural network, which outputs bounding boxes, class labels, and confidence scores for all detected objects. The game checks if any detected object matches your hunt list with a confidence threshold of ≥70%.
