At the CeBIT show in Germany, researchers have shown off an array of cutting-edge inventions, incorporating facial recognition and gesture-control tech
As sensors and cameras become smaller, new ways are being dreamt up for humans to interact with computers. ZDNet UK's sister site silicon.com rounds up everything from facial recognition to eye-tracking technologies on show at CeBIT 2011 in Germany.
Detecting changes in a person's mood when carrying out market research can be tricky and imprecise.
The Shore facial-detection system, from the Fraunhofer research organisation, is designed to identify and catalogue people's changing emotions using facial-recognition software.
The system works by looking for people's faces in a video and then suggesting their age, gender and facial expression. It is able to count the number of different people in shot, detect the expressions of multiple people in the same frame, and assess the expressions of people not directly facing the camera.
In the CeBIT demo, Shore categorised expressions as angry, happy, sad or surprised — with the system reportedly able to detect changes in facial expression between individual frames of video.
The institute suggests the system would be suited to judging audience reaction to signs, videos and products.
