11 results about "Eye detection" patented technology

There are two purposes of eye detection. One is to detect the existence of eyes, and another is to accurately locate eye positions. Under most situations, the eye position is measured with the pupil center. Current eye detection methods can be divided into two categories: active and passive eye detection [11].

A method for ultra-high sensitivity and specific naked-eye detection of trace aromatic compounds

ActiveCN117054345BAnalyteChemical compound
This invention relates to a method for ultra-high sensitivity and specific naked-eye detection of trace aromatic compounds. The method utilizes the long afterglow induced by the specific interaction between the analyte and a matrix as the output signal to achieve naked-eye detection of the analyte. The aromatic compounds are aromatic pollutants and aromatic organic metabolites. This invention utilizes the organic long afterglow induced by mixing the analyte G with the host molecule H through methods such as heating and melting, solvent evaporation and crystallization, matrix adsorption, and paper chromatography as a monitoring signal to achieve ultra-high sensitivity and specific naked-eye detection of trace aromatic compounds. The afterglow induced by the analyte G is highly dependent on the type and content of the analyte and matrix, which gives this detection method extremely high sensitivity and selectivity. The method is simple to operate, rapid, visible to the naked eye, requires inexpensive and readily available materials, and provides stable results.

Artificial intelligence gaze interface sensor (ai GIS): personalized biometric dual-camera foveal gaze tracking system with device-adaptive architecture for precise human gaze localization on digital and projected view planes

PendingUS20260194973A1PersonalizationAlgorithm
An Artificial Intelligence Gaze Interface Sensor (AI GIS) system and method for precisely tracking human gaze on a digital or projected view plane without head-mounted hardware. A context camera detects a user's face and matches it against stored biometric profiles using AI facial recognition, automatically loading personalized eye geometry, inter-pupillary distance and gaze calibration data. A conditional activation controller initializes a second Peregrine Foveal Camera (PFC), modeled after the dual-fovea retina of the Falco peregrinus, only upon confirmed eye detection. An AI algorithm triggers visual effects, hidden content, animations, gaze-based engagements and semantically mapped audio on the digital or projected plane based on gaze coordinate outputs, from a dedicated computational pipeline, correlated to the digital or projected plane. This invention serves as the sensing layer for U.S. application Ser. No. 18 / 395,290.
