We've all experienced that uncomfortable feeling you get when you realise someone has been standing behind you, watching what you're up to on the computer – and you're not quite sure how long they've been there.
Lenovo has come up with a way to stop that from happening: a smart assistant that uses your device's cameras, microphones and artificial intelligence software to detect when someone is standing behind you, or when you've left the device unattended.
Demonstrated at CES in Las Vegas, Lenovo's Smart Assist will give you a silent cue when someone has appeared in the background, and will automatically switch off the screen if it notices you've been gone for a while.
The voice recognition software Cortana and Amazon Alexa can also be adapted so that the device only reacts to the owner's voice. During video calls, it can block out the background entirely, and can apparently live-translate if you're talking to someone speaking a different language.
Lenovo also plans to improve its Thinkpad devices used by professionals to protect clients from data leaks or cyberattacks. Companies will be able to purchase the software Think Shield, which enables more security features for employees' computers. – dpa
