By default, panning (scrolling) and pinching gestures are handled exclusively by the browser. An application using Pointer events will receive a pointercancel event when the browser starts handling a touch gesture. By explicitly specifying which gestures should be handled by the browser, an application can supply its own behavior in pointermove and pointerup listeners for the remaining gestures. Applications using Touch events disable the browser handling of gestures by calling preventDefault(), but should also use touch-action to ensure the browser knows the intent of the application before any event listeners have been invoked.
Touch Blocker – Block screen touch v2.2.0
When a gesture is started, the browser intersects the touch-action values of the touched element and its ancestors, up to the one that implements the gesture (in other words, the first containing scrolling element). This means that in practice, touch-action is typically applied only to top-level elements which have some custom behavior, without needing to specify touch-action explicitly on any of that element's descendants.
A declaration of touch-action: none; may inhibit operating a browser's zooming capabilities. This will prevent people experiencing low vision conditions from being able to read and understand page content.
New coder here, I made a code for dragging/throwing an object and I wanted to know how to make it so that only part of the screen can be used for touch, i.e. only the bottom half of the screen can be touched. This is my gamescene code, and I'm using Swift 2.0.
The new code I added checks that the Y position of the touch is less than half the height of the scene, assuming the origin is at the bottom left. If the check fails, the function exits - you might want to add some code to cancel touch actions there.If you'd like a certain portion of the screen to be untouchable, you could make a CGRect and check that the touch location is always outside the rect, e.g:
Another approach is to use a "touch blocker". Since SpriteKit only registers the topmost touch, you could place a SKSpriteNode that uses the UIColor.clear color and set its isUserInteractionEnabled to true and its z position high enough that it's above the other touchable content. This will make a transparent region that "eats" touches on it.
This has the advantage of being simpler, and making it easy to turn the functionality off and on or easily change the affected area. But it also has some differences from Alessandro's approach. For instance, it doesn't block drags that would go up into its area; once the drag is established outside the area of the touch blocker, it will continue to receive touchesMoved events even if you drag your finger over the touch blocker's area. Either method would work. You just need to choose the one that works best for your particular needs.
The MacBook Pro "Core i5" 2.3 13-Inch (Mid-2018 True Tone Display, Touch Bar, Four Thunderbolt 3 Ports) is powered by a 14 nm, 8th Generation "Coffee Lake" 2.3 GHz Intel "Core i5" processor (8259U), with four independent processor "cores" on a single silicon chip, 128 MB of eDRAM embedded on the processor die, and a 6 MB shared level 3 cache. This notebook also packs 8 GB of onboard 2133 MHz LPDDR3 SDRAM (which could be upgraded to 16 GB at the time of purchase, but cannot be upgraded later), 256 GB or 512 GB of flash storage, and an integrated Intel Iris Plus Graphics 655 graphics processor that shares memory with the system.Externally, this notebook has an integrated 720p FaceTime HD webcam, a thin, backlit "third generation" butterfly mechanism keyboard with an integrated "Touch Bar" with a touch-sensitive control that adapts for different applications and provides Touch ID login support in lieu of traditional function keys, and a gigantic "Force Touch" trackpad.Additionally, it has a high-resolution LED-backlit 13.3" widescreen 2560x1600 (227 ppi, 500 nits) "Retina" display with True Tone technology, and a integrated battery that provides an Apple estimated 10 hours of runtime.This notebook is offered in either silver colored aluminum or a darker "Space Gray" colored aluminum housing (but not other colors) and weighs just a bit more than 3 pounds (1.37 kg).Connectivity includes 802.11ac Wi-Fi, Bluetooth 5.0, four "Thunderbolt 3" ports (USB-C connector), and a 3.5 mm headphone jack.Compared to its predecessor, this model has an improved display and keyboard as well as a more advanced processor and architecture.Also see:What are all the differences between the 13-Inch and 15-Inch "Mid-2018" MacBook Pro models?

In this project of we will learn How to design Touch-Based Door Lock System Using Arduino & Touch Sensor TTP223. Door Lock System using Arduino & TTP223 Capacitive Touch Sensor Switch is a simple project for switching circuit, i.e switching the servo motor on/off with the help of simple touch. The door can be locked or unlocked just by simply touching. We are using Touch Sensor TTP223 as a switch and LCD to display the status of door lock and LED to indicate on/off status as well.
The application area of this project is home and office where a simple touch can open and close the door. Interfacing touch sensor TTP223 with Arduino acts as a switch for unlocking the door.

In case of a saved contact, you can also unblock it directly from that contact's screen. All you need to do is to open the contact from your contacts list, tap the two-dot menu button, and then select Remove from Blacklist option.
Alternatively, you can unlock a previously blocked number/ contact directly from the call log. All you need to do is follow the steps that you took to block the number and then just tap the Unblock option from the number screen. 2ff7e9595c
