Keep looking at the center cross while watching for an edge signal.
Keyboard: Arrow keys · Touch or mouse: use the four labeled buttons · Pressing early counts as a miss
HOW TO PLAY
Start the test, sit comfortably, and keep your eyes on the center cross.
After a random wait, a labeled arrow appears at the top, right, bottom, or left edge.
Press the matching Arrow key or touch button. Standard mode always ends after 15 total trials.
SPATIAL AWARENESS
This game combines peripheral signal detection, direction recognition, and response selection. Holding your gaze on the fixation mark makes the edge cue a peripheral target.
Average time uses correct responses. Accuracy uses all trials, so wrong directions and early presses lower the result and still advance standard mode.
CONSISTENT TESTING
Keep the same viewing distance and screen size between attempts. Move the whole game into view before starting, then avoid following the signals with your eyes.
Keyboard, mouse, and touchscreens have different input delays. Compare runs made on the same device and treat this as a game, not a medical vision exam.
QUESTIONS
The average and best times use correct responses only. Accuracy is the percentage of all completed trials answered correctly. Every standard run contains exactly 15 trials.
No. Keep your gaze on the center cross and identify the labeled arrow without moving your eyes toward it. That is the core challenge of the game.
Each correct answer grows your streak and shortens the response deadline. A wrong direction, early press, or timeout ends the run.
Yes. Use the four large labeled touch buttons below the vision field. For a fair comparison, keep your viewing distance and device consistent.
