触摸支持^{(Touch Support)}是 Windows 11/10 的一项功能，仅适用于与触摸屏功能兼容的设备。如果您的机器没有触控功能，则此程序不适合您。让我们了解一下这个程序到底是什么以及如何使用它。2、5、10、20等触控点的^(Touch)触控^(Touch) 支持^(Support)是什么意思？什么是触摸屏上的^{(Touch Screen)}触摸^(Touch)点？这篇文章解释了一切。

我们将在这篇文章中介绍以下几点-

1. 全触控支持是什么意思？
2. 什么是屏幕上的触控点？
3. 支持 10 个触控点的触控
4. 支持 20 个触控点的触控
5. 我如何知道我的设备是否是触控式的？

触控点的^(Touch)触控^(Touch) 支持^(Support)是什么意思？

全触控支持是什么意思？

如果设备通过了 ( THQA )触控硬件质量保证^{(Touch Hardware Quality Assurance)}测试，则称该设备具有完整的触控支持。此测试验证您的 Windows Touch设备是否满足要求。

什么是屏幕上的触控点？

触摸屏中的触摸点^{(Touch Points)}基本上决定了设备如何同时感知触摸输入。例如，如果您有一个带有 2 个触控点的触控显示器，这意味着您的设备的显示器可以同时感应到两个触控输入，或者说，两个触控点可以在显示区域内检测到两个触控点的存在和位置。同样，带有 5 个触摸点的 Touch Support可以一次感应或检测 5 个手指的运动。

支持 10 个触控点的触控

10点触控支持^(Support)，也称为多点触控屏，是指可以同时感应和响应10点或20点接触的触摸屏。这种多点触控点的设置基本上是用来提高缩放、旋转、滑动、按下、轻弹和其他此类手势的准确性。因此，如果您的设备有 10 个触摸点，您可以一次在屏幕上使用全部十根手指。

支持 20 个触控点的触控

如果您想知道我们只有十个手指，那么支持 20 个触控点的触控是什么意思，让我来解释一下。这实际上意味着我们的设备支持手写笔输入（笔），一次可以输入 20 个输入。这种 20 个触摸点的设置通常用于绘图应用程序中，您需要在各个点上触摸屏幕。

我如何知道我的设备是否是触控式的？

要检查您的设备是否兼容触控，请转到设备管理器^{(Device Manager)}并打开人机界面设备^{(Human Interface Device)}。如果您看到任何启用或禁用 HID 兼容触摸屏的设置，则您的设备是触摸兼容的，如果不是，则不是。

我在设备管理器中没有看到符合 HID 的触摸屏设置^{(Device Manager)}

如果您知道自己有HID 触控投诉设备，但在^{(HID touch-complaint device)}设备管理器^{(Device Manager)}中看不到设置，则可能是您设备上安装的Windows不支持触​​控功能。

我如何知道我的设备支持多少个接触点？

转到Settings > System。向下滚动^(Scroll)并单击关于^(About)。

这将为您提供设备的详细规格，包括有关触控点触控支持的信息。

我没有触控兼容设备，但我的系统^(System)设置显示“支持 2 个触控点的触控”^(Touch)

如果您没有兼容触控的机器，并且在设置中仍然看到 Touch Support with 2 Touch Points，则表示您的机器上安装的Windows版本支持触控功能。它不适合你，你可以忽略它。

我们希望这篇文章澄清了这个主题。

What is is Touch Support with Touch Points in Windows 11/10?

Touch Support is a Windows 11/10 feature only for devices compatible with touchscreen functions. If your machine is not touch-enabled, this program is not for you. Let’s learn what exactly this program is and how to use it. What does Touch Support with 2, 5, 10, 20, etc Touch Points mean? What are Touch Points on a Touch Screen? This post explains all.

We will cover the following points in this post-

1. What does Full Touch support mean?
2. What are Touch Points On Screen?
3. Touch Support with 10 Touch Points
4. Touch Support With 20 Touch Points
5. How do I know if my device is touch?

What does Touch Support with Touch Points mean?

What does Full touch support mean?

A device is said to have full touch support if it passes the (THQA) Touch Hardware Quality Assurance test. This test verifies that your Windows Touch device meets the requirements.

What are Touch Points On Screen?

Touch Points in a touch screen basically determines how touch inputs a device can sense simultaneously. For example, if you have a touch display with 2 Touch Points, it means that the display of your device can sense two touch inputs at a time, or say, two can detect the presence and location of two touch points within the display area. Similarly, Touch Support with 5 touch points can sense or detect the motion of 5 fingers at a time.

Touch Support with 10 Touch Points

Touch Support with 10 points, also referred to as multi-touch screens refer to the touch screen which can sense and respond to 10 or 20 points of contact simultaneously. This setting of multi-touch points is basically used to give better accuracy with zoom, rotate, swipe, press, flick, and other such gestures. So if you have a device with 10 touch points, you can use all ten fingers on the screen at a time.

Touch Support With 20 Touch Points

If you are wondering that we have only ten fingers, what does a touch support with 20 Touch Points mean, let me explain. It actually means that our device supports a stylus input (pen) which can put 20 inputs in one go. This setting of 20 touch points is generally used in drawing applications, wherein you need to touch your screen on various points.

How do I know if my device is touch?

To check if your device is touch-compatible or not, go to the Device Manager and open Human Interface Device. If you see any settings to enable or disable HID-compliant touch screen, your device is touch-compatible and if not, it’s not.

I don’t see HID-compliant touchscreen settings in my Device Manager

If you know that you have an HID touch-complaint device and yet can’t see the settings in Device Manager, maybe the Windows you have installed on your device doesn’t support touch function.

How do I know how many touch points my device support?

Go to Settings > System. Scroll down and click on About.

This will give you the detailed specifications of your device including the information about touch support with touch points.

I don’t have a touch-compatible device but my System settings show ‘Touch support with 2 touch points’

If you don’t have a touch-compatible machine and still seeing the Touch Support with 2 Touch Points in settings, it means that the version of Windows installed on your machine supports the touch function. It’s not for you, you can just ignore it.

We hope that this post clarified the subject.
