چکیده
我々は 3次元眼球形状モデルを用いた視線測定法を 提案する.本手法は一般に視線を測定した場合に生じ る測定誤差発生要因を,モデルにおいてあらかじめ補 正しながら視線を算出する.そのため,算出された視 線と実際の視線との誤差が小さく,線形変換で補正が 可能である.一般には非線形補正をおこなうため,個 人キャリブレーションにおいて 5から 20点を用いるが, 本手法では最低 2 点で同等の測定精度が得られること を実験によって確認した.この結果,従来の視線測定 システムで問題であった,利用前に必要となる各種調 整の手間が大幅に軽減し,手軽に利用可能な視線測定 システムが実現された.

Estimation of Execution times for Tasks of Objects Counting and Localization Using the Ober2 Device
In the paper methodology is presented for eyetracking experiments, comprising human eyeball movements tracking during execution of objects counting and localisation tasks. The OBER2 device (based on infrared reflection method) has been used for registration of the eyeball movements. The algorithms for automatic estimation of observation times have been presented and evaluated. It was shown that...
متن کاملP58: Visual Working Memory Performance Based on Saccades in Children with and without Specific Learning Disorder: An Eye-Tracking Study
Some of the previous studies show that children with SLD have deficits in visual processing and working memory. Hence, the aim of this research was to investigate problems of visual working memory based on behavioral neuroscience method, using an eye tracker device. The method of present study was ex-post facto study. The participants included couple of twelve children with SLD (mean age=10.92)...
متن کاملOn Eye Gaze Determination via Iris Contour
We present a new approach for measuring the eye gaze using images that contains only one eye of a person. The model of the eye is investigated and gaze can be estimated by tracking the eyeball rotations. Iris contour is modeled as one planar circle and we estimate the ellipses of their projections onto a retinal plane. The unique solution of the orientations was obtained based on a geometric co...

متن کاملImproving Aviation Safety using Synthetic Vision System integrated with Eye-tracking Devices
. By collecting the data of eyeball movement of pilots, it is possible to monitor pilot’s operation in the future flight in order to detect potential accidents. In this paper, we designed a novel SVS system that is integrated with an eye tracking device, and is able to achieve the following functions:1) A novel method that is able to learn from the eyeball movements of pilots and preload or ren...
متن کاملA 3D Morphable Eye Region Model for Gaze Estimation
Morphable face models are a powerful tool, but have previously failed to model the eye accurately due to complexities in its material and motion. We present a new multi-part model of the eye that includes a morphable model of the facial eye region, as well as an anatomy-based eyeball model. It is the first morphable model that accurately captures eye region shape, since it was built from high-q...
