NEC has developed remote gaze detection technology that enables real-time detection of the direction in which an individual is looking, even when using existing camera technology.
“Based on this technology, NEC can evaluate the line-of-sight of pedestrians and help to optimise the placement of important announcements on public streets,” said Akio Yamada, GM, Data Science Research Laboratories, NEC Corporation.
“Moreover, the technology can contribute to the safety and security of our communities by helping to monitor the behaviour of suspicious individuals. This is in addition its business potential, where the technology can help retailers learn more about which products are attracting the most attention from visiting customers.”
Traditionally an individual’s line-of-sight is estimated using specialised devices equipped with infrared lights and advanced cameras that detect light as it is reflected from an individual’s eye.
NEC's technology, developed as part of its portfolio of artificial intelligence (AI) qqtechnologies, NEC the WISE, uses face feature point detection algorithms to accurately identify characteristics in and around the eye in images taken with conventional cameras. These devices can include web, surveillance, tablet and smartphone cameras, and additional specialised equipment is not required.
The technology even works with low resolution images and a range of lighting, and when the person is as much as 10m away from the camera. Furthermore, the line-of-sight of multiple individuals can be detected simultaneously, without compromising the accuracy of results.
Detection of line-of-sight can be determined with a measurement error of less than 5 degrees from the left, right, top and bottom, NEC says.
