A visual approach for driver inattention detection
Monitoring driver fatigue, inattention, and lack of sleep is very important in preventing motor vehicles accidents. A visual system for automatic driver vigilance has to address two fundamental problems. First of all, it has to analyze the sequence of images and detect if the driver has his eyes open or closed, and then it has to evaluate the temporal occurrence of eyes open to estimate the dri...
متن کاملInattention and the perception of visual feature conjunctions.
Visual processing of objects in the absence of focused attention appears to be limited. We varied the degree of attention, or visual processing, that observers paid to objects using an instruction set manipulation. In 2 experiments, subjects performed tasks that required superficial or detailed visual analysis of the objects involved. In subsequent recognition tests, information about conjuncti...
متن کاملVisual acuity development of children with infantile nystagmus syndrome.
PURPOSE Infantile nystagmus syndrome (INS) can be idiopathic or associated with ocular or systemic disease. The ocular oscillation of INS directly contributes to loss of visual acuity. In this study, visual acuity development in patients with INS was examined. METHODS Children with INS were classified as having idiopathic INS (n = 84) or INS with an associated sensory deficit: INS and albinis...
متن کاملVisual hemispatial inattention: stimulus parameters and exploratory strategies.
Patients with unilateral hemispheric lesions were given visual target cancellation tasks. As expected, marked contralateral and less severe ipsilateral visual inattention were observed in patients with right-sided cerebral lesions whereas those with left-sided lesions showed only mild contralateral neglect. Stimulus material (shapes vs letters) and array (random vs structured) interacted in a c...
متن کاملInfantile nystagmus adapts to visual demand.
PURPOSE To determine the effect of visual demand on the nystagmus waveform. Individuals with infantile nystagmus syndrome (INS) commonly report that making an effort to see can intensify their nystagmus and adversely affect vision. However, such an effect has never been confirmed experimentally. METHODS The eye movement behavior of 11 subjects with INS were recorded at different gaze angles w...
