Preattentive Test
CompletedThis is a small project developed to create a website that tests preattentive vision. The website aims to explore how preattentive processing functions in the human visual system.
The Preattentive Test project is a simple web app made to help people learn how our eyes and brain quickly notice things without us trying. Preattentive processing means the brain sees and understands some visual information automatically before we focus on anything.
Background: Preattentive vision helps us quickly find patterns, differences, or unusual things in what we see.
Purpose: This app is made to teach and show how preattentive processing works. It is useful for students learning about how we see, designers who want to make clear and easy-to-use interfaces, researchers studying how people use computers, and anyone curious about how our vision works.
Interactive Tests: The website has different simple tests where users spot color, form, and a combined test of form and color called the conjunctive test. Users can change settings like how many distractors appear and how long the screen blinks to find the target. Each test helps explain how we quickly notice certain features and why they catch our attention.
