Computers include video cameras, face recognition

Grader A: partial

Built-in webcams were common on 2009 notebooks, and Lenovo, Asus and Toshiba shipped face-recognition login. But the face login was not reliable: in February 2009 researchers defeated all three with a photograph of the owner. Reliable face identification of owners became mainstream only with Face ID in 2017.

Test: Two parts: built-in cameras on at least 50% of new notebooks (met or close in 2009); reliable face identification of owners (not met; below 5% in reliable form until 2017).

• Facial recognition fail (The Register) (2009-02-19): Lenovo Veriface III, Asus SmartLogon and Toshiba Face Recognition logins were defeated with photographs of the registered user.
• Webcam (Wikipedia) (retrieved 2026-09): Manufacturers began building webcams into laptop screens around the turn of the century.

Grader B: partial

Built-in webcams were common in 2009 notebooks. Reliable face recognition of owners was not routine: early laptop face-login was unreliable, and Kinect (2010) identified players only in one product; phone/PC face unlock became mainstream after 2014.

Test: Device test: webcams in >50% of new notebooks (hit); reliable owner face-ID well under 50% of new devices by 2014.

• Wikipedia: Webcam (accessed 2026-09-28): Makers began building webcams into laptop screens around 2000; no face-login data.
• Wikipedia: Kinect (accessed 2026-09-28): Kinect (Nov 2010) had facial recognition to identify users; 8M sold in 60 days.
