探索对五参数电刺激的主观反应揭示了一个嘈杂的感知空间。假设了一种降低噪声的方法，并通过比较沿能量梯度和离开能量梯度的强度区分阈值进行了实验验证。初步结果显示，沿梯度进行刺激时，阈值最高可降低60%。利用该方法实现了电触觉视觉替代装置中的最优强度控制。
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.
