### Effects of Users' Prior Experience on Agreement  
In our study, 33 participants were asked to perform gestures for HAR applications. We found that there was more agreement for users who have no prior experience with HAR for the tasks \"Long press on the target\" (0.343 vs. 0.124, _V_\({}_{\text{I0(2,N=33)}}=370.806\), \(p=0.003\)), \"Select the target\" (0.295 vs. 0.144, \begin{table}

Table 2: Agreement rate for 27 tasks in two categories: discrete and continuous with effects of users’ prior experience (experience with HAR application and using a wearable device). The highest agreement rates are highlighted in dark gray, while lowest are shown in light gray. Significance is highlighted in green. \(V_{b(2,N=33)}=177.859\), \(p=0.020\)), and \"Uniform scale up\" (0.171 vs. 0.052, \(V_{b(2,N=33)}=110.071\), \(p=0.052\)), while users with HAR experience achieved higher agreement for the tasks \"Move right\" (0.301 vs. 0.133, \(V_{b(2,N=33)}=217.095\), \(p=0.012\)), \"Move left\" (0.255 vs. 0.152, \(V_{b(2,N=33)}=81.504\), \(p=0.088\)), and \"Scroll down\" (0.229 vs. 0.124, \(V_{b(2,N=33)}=85.409\), \(p=0.082\)); see Table 2. Similarly, there was more agreement for participants who do not use a wearable device for the tasks \"End recording\" (0.275 vs. 0.105, \(V_{b(2,N=33)}=202.604\), \(p=0.019\)) and \"Select next section\" (0.392 vs. 0.2645, \(V_{b(2,N=33)}=18.881\), \(p=0.057\)) than those who use at least one wearable device.
