Subjects were required to keep a cursor in alignment with a moving target on a visual display unit screen using a mouse.
Designed by a creative team led by Abby Portner, the psychedelic chamber incorporated visuals from Black Dice who conceived the jumbo-sized visual and display screens for the band's Coachella set.
While the most obvious innovations of the DS -- touch screens and a visual display across multiple screens -- are not cutting-edge, they are unexplored in video games.
The claim that visual display units (VDU -screen filters improVDU -screeny reducing exposure to electrical filtersand/or improveng screen legibility was investigated by introducing VDU screen filters into an office environment.
However, it remains possible that the visual display and the screen-edge luminance contribute to changes in occipital activity, specifically within the anterior parts of the calcarine representing eccentric parts of the visual field.
Several systems, including Microsoft's Kinect sensor and the LeapMotion, have pushed technology which monitors a user's hand and body motions to allow them to interact with a computer interface, but have lacked any sort of feedback, bar audio and visual alerts from a display screen.
A video-projector, with a refresh rate of 75 Hz, placed behind the screen and connected to a PC, back-projected the visual stimuli onto the display screen.
The visual display consisted of a screen with three white squares (each of 0.5° degree of visual angle) at a distance of 8° on black background with the central square located at the center of the screen (see Fig. 1A).
During scanning, the visual display was backprojected onto a screen viewed via a mirror mounted on top of the MR head coil.
When the onset of the horizontal –voluntary – saccade was detected (eye velocity reaching a 70 90°/sec threshold), the entire visual display was shifted horizontally toward the screen centre.
