What is Search the Screen?

Search the Screen is a visual scanning game that trains peripheral vision and divided attention. The screen is divided into four quadrants, each filled with a grid of letters, numbers, or icons. One target is chosen at the start — your task is to click every instance of that target across all four quadrants while keeping your eyes fixed on the red dot in the centre. This forces your peripheral visual system to identify and locate targets rather than relying on foveal (central) vision scanning, which is the core skill used in reading line-by-line, driving, and many sports.

How the game works

Configure your session by choosing the target type (letters, numbers, or icons), the grid density for each quadrant (2×2 to 16×16), the number of targets to place per quadrant, and whether to show grid lines. Press Start to generate the grids; a preview overlay shows you what to look for and how many instances are hidden. Click OK to begin the timer. Click every target you find — correct clicks are circled in green, wrong clicks in red. The session ends automatically when all targets have been found.

Peripheral vision and visual attention

The human retina has two functional zones: the fovea, which provides sharp detail but covers only about 5° of visual angle, and the peripheral retina, which covers a wide field but at lower resolution. Most everyday visual tasks — driving, sport, navigating a crowd — rely heavily on peripheral detection followed by rapid foveal confirmation. Fixation training, where gaze is anchored to a central point while attention is directed outward, has been shown in sports-science and rehabilitation research to measurably expand the usable field of peripheral detection. Regular practice with increasing grid densities progressively extends this working range.

Tips to improve your scanning

Resist the urge to move your eyes off the centre dot — this defeats the purpose of the exercise and trains the wrong skill. Start with a small grid (4×4 per quadrant) and a high-contrast target type (letters or numbers) before progressing to denser grids or icon targets. Use quadrant-level scoring in the results to identify which part of your visual field is weakest, then set that quadrant to a higher difficulty while keeping the others smaller. Short sessions of three to five minutes at high concentration are more effective than long inattentive ones.

FAQ

Why do I have to keep my eyes on the centre dot?

The game is specifically designed to train peripheral vision, not central scanning. Moving your eyes to each target defeats the purpose of the exercise. The challenge — and the training benefit — comes from detecting and clicking targets using the edges of your visual field while your gaze stays fixed.

What does the Random fill option do?

By default each quadrant uses the same pool of distractor characters repeated to fill the grid. Enabling Random fill draws distractors from a larger varied pool so the grid looks more varied, which is harder because the target is less salient by contrast.

Does a harder grid (16×16) always mean a harder game?

Yes, for peripheral detection — more items per quadrant means a denser visual scene and smaller individual elements, both of which challenge peripheral resolution. You can also increase difficulty by reducing targets per quadrant (harder to spot with fewer in a dense grid) or by using icons instead of letters.
