Multi-Zone Touch Counter

How the Multi-Zone Touch Counter Works

The Multi-Zone Touch Counter splits the screen into separate regions and keeps a separate total for each region. The tool reads the X and Y position of every tap and adds 1 to the zone that contains that point.

1. Choose a zone layout: Pick 2, 4, 6 or 9 zones. A 2 × 2 grid gives 4 equal quarters of the screen.
2. Label each zone: Name zones by what they count, such as Adults, Children, Bikes and Cars.
3. Tap the right zone: Tap inside a zone to raise that zone's total by 1. The other zones stay the same.
4. Read the grand total: The tool adds all zone totals into one overall figure.

Multi-Zone Touch Counter Formula

The Multi-Zone Touch Counter zone index equals the row number multiplied by the column count, plus the column number. Each tap adds 1 to that zone.

x, y

Tap position in pixels

W, H

Counter width and height in pixels

R, C

Number of rows and columns

floor( )

Rounds down to a whole number

Example: A 400 × 400 px surface uses a 2 × 2 grid. A tap at (300, 100) gives floor(100 ÷ 400 × 2) × 2 + floor(300 ÷ 400 × 2) = 0 × 2 + 1 = Zone 1, the top-right quarter.

About the Multi-Zone Touch Counter

A Multi-Zone Touch Counter is a screen divided into tap regions, with each region acting as its own tally counter. One device replaces several hand clickers.

Zone counting suits jobs where items fall into fixed groups. A traffic survey records cars, trucks, buses and bikes in 4 zones, and the counter keeps all 4 numbers plus a combined total.
