视野计是用于在临床环境中测量视野的各种属性的市售仪器。与传统的基于实验室的系统相比，它们在进行视觉实验方面具有几个优势，包括内置的凝视跟踪和校准，抛光的外观以及增加参与者舒适度的属性。在这项工作之前，没有标准来控制这些仪器，这使得将它们用于新颖的心理物理实验变得困难和耗时。本文介绍了开放式视野计接口（OPI），这是一套可用于控制视野计的标准功能。目前，该标准在两种商业上可用的仪器上部分地以开源编程语言R实现：Octopus 900（由瑞士Haag-Streit生产的基于投影的碗周界）和Heidelberg Edge Perimeter（由德国Heidelberg Engineering生产的基于CRT的系统），允许这些仪器用作心理物理实验的平台。
Perimeters are commercially available instruments for measuring various attributes of the visual field in a clinical setting. They have several advantages over traditional lab-based systems for conducting vision experiments, including built-in gaze tracking and calibration, polished appearance, and attributes to increase participant comfort. Prior to this work, there was no standard to control such instruments, making it difficult and time consuming to use them for novel psychophysical experiments. This paper introduces the Open Perimetry Interface (OPI), a standard set of functions that can be used to control perimeters. Currently the standard is partially implemented in the open-source programming language R on two commercially available instruments: the Octopus 900 (a projection-based bowl perimeter produced by Haag-Streit, Switzerland) and the Heidelberg Edge Perimeter (a CRT-based system produced by Heidelberg Engineering, Germany), allowing these instruments to be used as a platform for psychophysical experimentation.
