How many fingers can ipad detect

Tap "Continue" when it's done. Alternatively, you could perform the two-finger scan by alternating the fingers throughout the whole process.

Scan one finger, wait for the buzz, pick it up, place the other finger on the scanner, wait for the buzz, pick it up, and repeat. It's a lot more confusing and doesn't seem to work any better than the first method, so we suggest sticking with that one. After you tap the final "Continue," iOS will save your two-finger scan alongside any other scan you might already have.

Tap the new scan to change its name to something more specific, such as "left and right pinky," so you don't get confused by which fingers you've scanned and which you still need to do.

But if you have, you've also learned that it's more difficult to use one when your fingers are wet. Touch ID was particularly prone to failing when you were cooking, or had just washed your hands, for instance. Now a newly-granted patent shows that Apple is looking at ways to compensate for moist fingertips and allow screens to react the way you want them to. Usually force is thought of as in the amount of pressure put on a screen, or the "more energy transfer out of the [screen] indicates more contact and, therefore, indicates more force being applied.

So if the screen can detect just how damp a person's finger is, it can recalibrate itself to better determine when a touch is a deliberate press or not. It could work on the basis that a damp finger pressed against the screen spreads out slightly more than a dry one does.

Although it also notes that regardless of environmental conditions, "certain users may have sweaty, moist or wet hands that may provide better wetting while others may have dry hands. The patent describes having a calibration device "aimed at determining a current state of a user's fingerprint.

Most of the rest of the patent examines different types of devices for which this may be of use, and specifics of how procedures would then vary. Overall, though, the aim is to figure out the degree of dampness on a user's finger. Then it's all about extrapolating from that dampness reading and the size of the person's fingerprint on the device, exactly when to react as if touched or tapped.

The patent is credited to two inventors, Duncan Kerr, and Steven P. The latter's previous related work includes a patent regarding biometric authentication techniques. This new patent is not the first time Apple has attempted to make touch screens more usable in damp conditions.
