This article mainly introduces how Windows 10 21H2 automatically unlocks the computer by detecting the presence of people, which has a certain reference value. Interested friends can refer to it. I hope you will gain a lot after reading this article. Let's take a look at it.

The code of Windows Preview Build 22353 shows that it can detect artificial memory and Windows is about to introduce new locking and unlocking options.

The latest version of Windows10 Beta has the ability to unlock PC as you approach it, and you can set PC to unlock when you are at a distance from your computer.

If multiple devices that can measure distance are connected, Windows will allow you to select a sensor to detect the distance between you and the PC.

Windows can use Bluetooth and infrared cameras to detect human presence.

Currently, there is no information on which sensors Windows will use to detect human presence.

However, considering that the operating system provides the ability to lock and unlock PC based on distance, it may use a Bluetooth device, such as a smartphone, to measure distance.

Once you feel that you are near the PC, you can use an infrared camera to authenticate the computer.

3. Some laptops already provide HPD-based locking / unlocking

Automatic locking and unlocking is not a new feature. Some brands such as Dell, Hewlett-Packard, Lenovo and Sony have recently launched laptops with human presence detection (HPD) capabilities.

Dell's Latitude 7400 2-in-1 uses its infrared camera to detect human presence. Once the user is detected, it uses the same camera to scan the face and verify the PC identity.

4. This feature may make its debut in the Windows 10 Sun Valley update.

Currently laptops with HPD-based authentication use custom software. If HPD is integrated into Windows, laptops with compatible hardware can take advantage of this feature without any additional steps.

The launch date of the Windows HPD feature is currently unknown. The upcoming Windows 10 Sun Valley update may be a great opportunity for Microsoft to introduce this feature.
