I’m excited to note that the Dell Latitude 7400 2 won a CES Innovation Award at CES 2019, partially because of the stellar features that I helped to design and implement at Intel as leader of the Intel Context Sensing team.
The Dell Latitude 7400 2 -in-1 is the world’s smallest commercial 14” 2-in-1 targeting up to 24 hours of battery life-first to feature a PC proximity sensor enabled by Intel Context Sensing Technology.
The Express Sign-In feature on the new Dell Latitude 7400 2-in-1 is a special security feature that makes use of Windows Hello technology in order to lock your device when you’re away from the computer, and then unlock it automatically when you come back to it.
The device’s IR camera, which is located above the screen, constantly checks for your face once you set up your Windows Hello facial recognition. If it stops detecting you, it will lock down your device after a certain amount of time (you can choose how long it takes in settings). Since the camera continues to remain active even in this locked, sleep mode state, it will immediately sign you back in and unlock your screen once it detects your face again. This is a fantastic feature if you need to get up for a bit, but don’t want anyone to see what you’re doing on your Dell Latitude 7400 2-in-1.
In Windows Central testing, the Express Sign-In feature worked flawlessly and the testing team had no issue with either the locking or unlocking functions. The camera itself is capable of detecting facial patterns wonderfully, so you can expect Express Sign-In to work great on your own Dell Latitude 7400 2-in-1.
