How the Per-Finger Touch Counter Works
The Per-Finger Touch Counter keeps a separate count for each touch identifier, so every finger on the screen gets its own tally. The browser assigns a pointer ID to each contact, and the tool adds 1 to the matching tally on each touch start.
- Touch with several fingers: Each finger gets a numbered label such as Finger #1, Finger #2 and Finger #3.
- Tap in turn: Lift and tap each finger. The tool assigns the contact to a finger slot by order of arrival and screen position.
- Compare totals: Read each finger's count side by side to see which finger taps most often.
- Reset slots: Press Reset to clear all finger tallies and pointer slots.
Per-Finger Touch Counter Formula
The Per-Finger Touch Counter value for one finger equals the number of touch starts linked to that finger's slot. The overall total equals the sum of all finger tallies.
- f
- Finger slot number, such as 1 to 10
- Starts
- Touch-start events
- slot
- Finger slot matched to the pointer ID
Example: Finger #1 taps 30 times, Finger #2 taps 22 times and Finger #3 taps 18 times. The total is 30 + 22 + 18 = 70. Finger #1 holds 30 ÷ 70 = 42.9% of all taps.
Per-Finger Touch Counter Reference Table
The Per-Finger Touch Counter conversion table converts finger tallies into shares of the total. The example uses a 100-tap session.
| Finger | Tap count | Share of total | Taps per 10 s session |
|---|---|---|---|
| Thumb | 28 | 28% | 2.8 per s |
| Index | 32 | 32% | 3.2 per s |
| Middle | 21 | 21% | 2.1 per s |
| Ring | 12 | 12% | 1.2 per s |
| Little | 7 | 7% | 0.7 per s |
| All fingers | 100 | 100% | 10.0 per s |
About the Per-Finger Touch Counter
A Per-Finger Touch Counter is a multi-touch tool that splits tap totals by individual contact. Each pointer ID represents one finger for as long as that finger stays on the screen.
Browsers reuse pointer IDs after a finger lifts, so the tool matches new contacts to finger slots by position. The result is a per-finger breakdown that shows finger balance, finger strength and finger independence.
Ways to Use the Per-Finger Touch Counter
There are 5 main uses of the Per-Finger Touch Counter, including hand therapy and piano finger drills.
- Hand therapy: Therapists track tap counts for a weak finger during rehabilitation after injury or stroke.
- Piano finger drills: Pianists balance tap counts across all 5 fingers of each hand.
- Typing practice: Typists find which fingers take on too much work.
- Multiplayer tablet games: Each player keeps one finger on the screen and gets a separate score.
- Touch controller testing: Engineers confirm pointer IDs stay stable while fingers move.
