low-level touch events as input to the application. Applications such as "Piano" or complex controls, such as multiple sliders for users to manipulate at the same time, are good examples. Run MS Paint, select a drawing tool from the toolbox, and then draw with your 4 fingers (if supported by hardware): In this hands-on experiment, we'll use the "good" approach. The "good" approach is the easiest way to get touch events for your application, and can be used to customize scaling, rotation, and

On Ubuntu, you can install fprint-demo and fingerprint-gui as the fingerprint recognition software for ThinkPad. I tried fprint-demo, which can be used with the Ubuntu SYSTEM account, but the recognition effect is poor. Fingerprint-gui runs as an independent fingerprint software, and the recognition effect is good. The

As long as the algorithm is well designed, the fingerprints of any two pieces of information are hard to duplicate, just like human fingerprints. Information

Use iOS 8 SDK to add Touch ID fingerprint recognition The iOS 8 SDK exposes the Touch ID fingerprint recognition feature to developers, allowing apps to locally verify user identities. It is very easy to use Touch ID. It only takes two steps: 1. Check whether the Touch ID is available. 2. Obtain the fingerprint verification result. The following is a simple examp

Apple launched a new version of the IOS8 system at the WWDC2014 Opening ceremony on June 3, 2014, with little change in the interface between IOS8 and IOS7, but only in functional terms. The IOS8 notification Hub is more powerful, supports message direct reply operations, and supports QuickType and third-party input methods. SMS features improved significantly, support group chat. Send voice, video, share locations, and more. From the point of view of the end user. Many of the new features of IO
