HumTouch是一种触摸感应方法，可以将物体表面变成触摸传感器。该传感方法利用人体的电流泄漏，因此，定位性能表现出个体差异。在本文中，我们研究的本地化性能的HumTouch涉及多个参与者。实验中使用了一张标有49个点的半导体纸。5名参与者参与实验，定位结果通过留一法交叉验证进行评估，其中使用从4名参与者收集的样本建立估计模型来定位最后一名参与者的触摸。对于五名参与者中的四名，平均估计误差小于或等于1厘米，这与指尖的大小相当。这表明HumTouch有可能应用于多个参与者，而无需针对特定人员进行事先校准。
HumTouch is a touch sensing method that can turn object surfaces into touch sensors. The sensing method utilizes the current leak from the human body; therefore, the localization performance exhibits individual differences. In this paper, we research the localization performance of HumTouch involving multiple participants. A semi-conductive paper marked with 49 points was used for the experiment. Five participants participated in the experiments and the localization results were evaluated via leave-one-out cross validation, in which an estimation model was established by using the samples collected from four participants to localize the touch of the last participant. For four out of the five participants, there were mean estimation errors smaller than or equal to 1 cm, which is comparable to the size of a fingertip. This indicates that HumTouch has the potential to be applied to multiple participants without prior calibration conducted for a specific person.
