On the Time Constants of Tachistoscopes*
The time constants of commercially available, electronic tachistoscopes are shown to be much poorer than is widely assumed. When a band near the centre of the visible spectrum is isolated, the output of a typical tachistoscope lamp takes approximately 18ms to reach 90% of its asymptotic value; the time to decay to 10% is also typically 18 ms and we demonstrate conditions under which the decayin...
متن کاملAn LCD tachistoscope with submillisecond precision.
Tachistoscopes allow brief visual stimulation delivery, which is crucial for experiments in which subliminal presentation is required. Up to now, tachistoscopes have had shortcomings with respect to timing accuracy, reliability, and flexibility of use. Here, we present a new and inexpensive two-channel tachistoscope that allows for exposure durations in the submillisecond range with an extremel...
متن کاملComparing Different Layouts of Tag Clouds: Findings on Visual Perception
With the emergence of social tagging systems and the possibility for users to extensively annotate web resources and any content enormous amounts of unordered information and user generated metadata circulate the Web. Accordingly a viable visualisation form needs to integrate this unclassified content into meaningful visual representations. We argue that tag clouds can make the grade. We assume...
متن کاملVisual Perception in Computer Graphics Education
Computer graphics education is increasingly important to supply the growing needs of the film, games and virtual reality industries. These industries are demanding ever more realistic computer generated environments. Despite the ready availability of modern high performance graphics cards, the complexity of the scenes being modelled and the high fidelity required of the images means that synthe...
متن کاملSteady-state visual evoked potentials to computer monitor flicker.
In the present study, steady-state visual evoked potentials (S-VEP) in response to amplitude-modulated light from a computer monitor (colour sVGA, 15-inch tube) have been examined. S-VEPs to computer monitors with different refresh rates (60 Hz or 72 Hz) and screen brightness (65 cd/m2 or 6 cd/m2) were recorded in 13 subjects with normal or corrected-to-normal vision. EEG samples were amplified...
