Touch-and-Release Counter

How the Touch-and-Release Counter Works

The Touch-and-Release Counter adds 1 only when a contact both starts and ends on the counting surface, forming one complete touch cycle. A touch that starts on the surface and slides off before lifting does not count.

1. Touch the surface: A touch start opens a cycle for that finger's pointer ID.
2. Lift on the surface: A release inside the surface closes the cycle and adds 1.
3. Slide off to cancel: Lifting outside the surface leaves the cycle incomplete, and the count stays the same.
4. Compare open and closed cycles: The display shows completed cycles and abandoned touches.

Touch-and-Release Counter Formula

The Touch-and-Release Counter total equals the number of pointer IDs with a matched start and end inside the surface. Completion rate equals completed cycles divided by touch starts.

Start(id)

Touch start for pointer id

End(id)

Release for the same pointer id

Starts

All touch starts

Example: A user makes 60 touch starts, and 54 end on the surface. Cycles = 54. Completion = 54 ÷ 60 × 100 = 90%.

About the Touch-and-Release Counter

A Touch-and-Release Counter is a counter that tallies full contact cycles from touch start to touch end. The tool follows the same rule as a standard on-screen button, which fires on release, not on press.

Firing on release gives users a way to back out: sliding the finger off a button cancels the action. The counter measures how often users complete or abandon touches.

Ways to Use the Touch-and-Release Counter

There are 5 main uses of the Touch-and-Release Counter, including button behavior tests and cancel-rate research.

• ✓Button behavior tests: Developers confirm buttons fire on release inside the target.
• ✓Cancel-rate research: Designers measure how often users slide off a button to cancel.
• ✓Deliberate counting: Users count only complete presses and skip half touches.
• ✓Switch testing: Testers count full press-and-release cycles of touch buttons.
• ✓Motor assessment: Therapists track how many touches end on target.
