| Remarks: |
Typographical errors in the ACM version of "W-Air: Enabling Personal Air Pollution Monitoring on Wearables": All CO2 concentrations and RMSE metrics are measured in ppm and not ppb as stated
in the published version. (Table 2, 3, 4, 5, 6 and Figure 5.c, 5.d) The errors have no effect on the results and conclusion of the paper and have been fixed in the version available here.
Additional factors creating human interference: In Section 3 we list different VOC emssision sources that cause human interference on the two MOX sensors used in the measurement study. There are
potentially more factors causing notable interference on the sensors. Namely, 1) humidity and temperature changes due to the closeness to the body and 2) hydrogen (H2), which is a component of
human breath and a cross-sensitivity of the sensors. |
