We sought to understand the basis of performance variability and perceptual learning in saccadic visual search. Four subjects searched for a target based on its shape in a linear array of densely packed, regularly spaced items, a configuration used to simplify the analysis of performance and to minimize search strategy variability. We measured the dependence of performance-search speed-on the o...

OBJECTIVE To investigate the relationship between silent reading performance and visual field defects in patients with glaucoma using an eye tracking system. METHODS Fifty glaucoma patients (Group G; mean age, 52.2 years, standard deviation: 11.4 years) and 20 normal controls (Group N; mean age, 46.9 years; standard deviation: 17.2 years) were included in the study. All participants in Group ...

It has recently been found that adult native readers of Thai, an alphabetic scriptio continua language, engage similar oculomotor patterns as readers of languages written with spaces between words; despite the lack of inter-word spaces, first and last characters of a word appear to guide optimal placement of Thai readers' eye movements, just to the left of word-centre. The issue addressed by th...

The purpose of the present study was to examine in 7 years old normal children who just learnt to read, saccade and fixation characteristics during reading single words. Eight children were studied and their results were compared to those of eight normal adults doing the same task. For each group word reading data were also compared with data in a task requiring saccades and fixations to target...

PURPOSE To conduct a prospective randomised controlled study to compare the stability and risk of nerve injury between fractures treated by medial-lateral pin fixation and those treated by 2-lateral pin fixation. METHODS Patients with displaced supracondylar fractures admitted between May 2000 and December 2001 were recruited into the study. They were randomised to treatment either with media...

Previous studies have found that words are identified most quickly when the eyes fixate near the word center (the Optimal Viewing Position, OVP) in alphabetic languages. Two experiments were performed to determine the presence of OVP effects during the processing of isolated Chinese words. Participants' eye movements were recorded while they performed a lexical decision task. The results sugges...

BACKGROUND Appropriate treatment of acromioclavicular joint dislocation is controversial. Acroplate fixation is one of the most common treatment methods of acromioclavicular joint (ACJ) dislocation. Based on the risk of re-dislocation after Acroplate fixation, we assumed that combined fixation with an Acroplate and a coracoclavicular screw helps improve the outcome. OBJECTIVES The main purpos...

Websites are the important interfaces in HCI (Human–Computer Interaction). Website design significantly affects online shopping behavior. This research used eye-tracker to track the eye-movement proce...

OBJECTIVE This study aimed to demonstrate that the lengthening technique of an external fixator associated with locked intramedullary nail is an efficient method that decreases the duration of the external fixation and improves the rehabilitation period. METHODS From January of 2005 to May of 2014, 31 patients with mean lower limb discrepancy of 5.31 cm were treated. The etiologies of the def...
