FAQ: What are the recommended Display PC specifications for Experiment Builder?
The requirements for the Display PC depend greatly on the type of experimental paradigms that the eye tracker will be used for. For example, gaze-contingent paradigms generally require more computing power and may require higher-end video hardware than simple cognitive paradigms because the computer display needs to be updated at higher refresh rates. Similarly, video and audio intensive experiments may need faster hard disks to support the transfer of large video file data to the computer in a timely manner.

The following requirements are suggestions for a Display PC configuration that should be able to handle most experimental requirements:
  • 64-bit Windows 10/11; or Mac OS X 10.6.8 or higher (note see footnote about Compatibility Limitations).
  • Recent Intel CPUs with duo-core/multi-core processor
  • 250 GB or larger hard disk with 7,200 or higher rpm, or solid-state hard drive
  • Video card that has 1 GB or more of dedicated video memory and supports a refresh rate of 100 Hz or higher.
  • At least 4 GB RAM
  • A dedicated Ethernet port to connect Display PC to the EyeLink 1000 Plus Host PC
  • A keyboard and mouse
  • Free USB port (for the EyeLink Data Viewer/SR Research Experiment Builder license USB-key, if using these applications)
  • Optional - ASIO compatible Soundcard for precision audio playback in Windows.
  • Optional - Ethernet card for use on local network or internet access
  • Optional - Parallel Port for sending/receiving synchronization pulses to/from EEG, MEG, MRI, or other third-party devices (only an option to consider if experiments require syncing with these other devices)

macOS - Compatibility Limitations
Experiment Builder 2.3.x adds support for recent versions of macOS (Sierra, High Sierra, Mojave, & Catalina). Please note that inconsistency in visual stimulus presentation timing / delayed stimulus onset has been observed in these recent macOS releases. While users can use macOS to develop and debug experiments, they are advised to use Experiment Builder on a Windows PC system for actual data collection when display timing is critical.
