Focus Meter

The Focus Meter measures sustained attention and visual search accuracy through a progressive target detection task. It evaluates how consistently a specific target can be identified within a dense visual field as complexity increases over a fixed duration.

How It Works

A 10x10 grid of random digits is displayed. You identify and click all instances of a specified target digit before it changes. The target changes every 15 seconds. Visual complexity increases across 6 levels over 90 seconds through higher digit density and faster target changes.

What Gets Measured

Accuracy per level — proportion of target instances correctly identified within each 15 second interval.

Consistency across levels — degree to which accuracy is maintained as visual complexity increases.

Performance trajectory — accuracy change from early levels to later levels, indicating how sustained attention holds under progressive load.

Understanding Your Results

Stable accuracy across all six levels suggests sustained attention capacity is maintained under increasing visual complexity. Declining accuracy in later levels is common and reflects increasing attentional load rather than a fixed capacity ceiling. Accuracy drops concentrated in specific levels may correspond to particular complexity thresholds rather than general attention difficulty.

Limitations

This test measures sustained visual attention within a digit detection task specifically. It does not assess auditory attention, reading concentration, or sustained attention in conversational or task-switching contexts. Performance is sensitive to screen size, display quality, ambient lighting, and visual fatigue at time of testing. The 90 second duration captures short-term attention consistency and does not reflect sustained attention capacity over longer work periods.
