Abstract

Probing the subjective response to a five-parameter electrocutaneous stimulus has revealed a noisy perceptual space. A method for reducing the noise is hypothesized and experimentally tested by comparing the intensity discrimination thresholds along and off the energy gradient. Preliminary results show a reduction of the threshold of up to 60% when stimulating along the gradient. The method is exploited to implement an optimal intensity control in an electrotactile vision-substitution device.

摘要

对五参数电皮肤刺激的主观反应进行探究后发现了一个嘈杂的感知空间。通过比较沿能量梯度和偏离能量梯度的强度辨别阈值，提出并通过实验测试了一种降低噪声的方法。初步结果表明，沿梯度刺激时阈值降低高达60%。该方法被用于在电触觉视觉替代设备中实现最佳强度控制。
