Purpose

The objective of this work is to evaluate the performances of a novel integrated device, based on passive head-mounted display (HMD), for the pattern reversal visual evoked potential (PR-VEP) clinical test.

Methods

Google Cardboard® is used as passive HMD to generate the checkerboard pattern stimuli through an Android® application. Electroencephalographic signals are retrieved and processed over 20 subjects, 12 females and 8 males between 20 and 26 years. Morphological PR-VEPs and frequency response were compared with previous literature results, to test the reproducibility and the efficacy of the proposed solution.

Results

PR-VEPs evoked by our novel prototype showed typical triphasic waveforms in moderate agreement with those obtained with other more expensive HMDs and standard commercial devices. Statistical analysis did not highlight strong differences among the systems over the features analyzed except for the P100 amplitude and peak time (**p < 0.005).

Conclusion

The proposed solution opens the door for a new generation of non-invasive first-level diagnostic devices of optic nerve pathologies inexpensive and easy to access.

一种用于测量由被动头戴式显示器刺激器诱发的视觉电位的新系统

目的

这项工作的目的是评估一种基于被动头戴式显示器 (HMD) 的新型集成设备在模式反转视觉诱发电位 (PR-VEP) 临床测试中的性能。

方法

Google Cardboard® 用作被动 HMD，通过 Android® 应用程序生成棋盘图案刺激。在 20 至 26 岁之间检索和处理 20 名受试者、12 名女性和 8 名男性的脑电图信号。将形态 PR-VEP 和频率响应与以前的文献结果进行比较，以测试所提出解决方案的重现性和有效性。

结果

我们的新型原型诱发的 PR-VEP 显示出典型的三相波形，与其他更昂贵的 HMD 和标准商业设备获得的波形适度一致。除了 P100 幅度和峰值时间（** p  < 0.005）外，统计分析并未突出系统之间在所分析特征上的强烈差异。

结论

所提出的解决方案为新一代廉价且易于访问的视神经病理学非侵入性一级诊断设备打开了大门。
