Stimuli were presented on a VIEWPIXX 3D monitor (VPixx Technologies, Saint-Bruno, QC, Canada), viewed from a distance of 96 cm. The monitor screen was 52 cm wide and 29 cm tall. The screen resolution was 1920 × 1080 pixels, with a refresh rate of 120 Hz. Each pixel subtended 1 arc min. Stimuli were presented at 8-bit resolution. Stereoscopic presentation was achieved using a 3DPixx IR emitter and NVIDIA 3D Vision LCD shutter glasses (NVIDIA, Santa Clara, CA, USA). Gauge settings were made using the computer mouse. Stimuli were generated and presented using MATLAB (Mathworks, Natick, MA, USA)and the Psychophysics Toolbox extensions [65 (link),66 (link),67 ].
3d vision lcd shutter glasses
Manufactured by NVIDIA
Sourced in United States
The 3D Vision LCD shutter glasses are a hardware component designed to work in conjunction with compatible NVIDIA graphics cards and displays to enable stereoscopic 3D visualization. The glasses use active-shutter technology to alternate the image presentation between the left and right eyes, creating a perceived 3D effect.

The phase, motion, and dOKN test were conducted for all subjects in the same dimly lit room (illumination of 100 lux). The visual stimuli were generated and controlled by MATLAB with Psychophysics Toolbox extensions (MathWorks, Inc., Natick, MA) displayed on an ASUS 3D monitor (VG278, 144-Hz refresh rate, 1,920*1,080 resolution, Taiwan). The subjects’ heads were fixed with the help of a chin rest, and the viewing distance to the monitor (597 mm*336 mm, background brightness of 35 cd/m2) was 57 cm. During stimulation, NVIDIA 3D VISION LCD shutter glasses (Santa Clara, CA) were used to create a dichoptic viewing state on the subjects. An extra pair of refractive-corrected glasses were used in the subjects with refractive errors.

Stereoscopic presentation was achieved using a 3DPixx IR emitter and NVIDIA 3D Vision LCD shutter glasses. The cross-talk between the left and right images, measured using a Minolta LS-110 photometer, was 0.12%. Participants’ responses were recorded using a RESPONSEPixx response box. Stimuli were generated and presented using MATLAB and the Psychophysics Toolbox extensions (Brainard, 1997 (link); Kleiner, Brainard, & Pelli, 2007 ; Pelli, 1997 (link)).

Stimuli were presented on a VIEWPIXX 3D monitor, viewed from a distance of 130cm. The monitor screen was 52cm wide and 29cm tall. The screen resolution was 1920x1080 pixels, with a refresh rate of 120Hz. Each pixel subtended 0.72 arc min. Stimuli were presented at 8-bit resolution. Stereoscopic presentation was achieved using a 3DPixx IR emitter and NVIDIA 3D Vision LCD shutter glasses. The crosstalk between the left and right eyes’ views, as measured with a Minolta LS110 photometer, was 0.12%. Participants’ responses were recorded using a RESPONSEPixx response box. Stimuli were generated and presented using MATLAB and the Psychophysics Toolbox extensions [60 (link)–62 ].
About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
