<p>Based on the results, we argued that:</p>
<ol>
<li>As it stands, the only tradition in HCI is that of having no tradition in terms of research topics.</li>
<li>The accumulated knowledge in HCI is almost exclusively grounded on very specific technological contexts. In addition, due to the rapid pace of technology designed for humans, knowledge in HCI tends to be highly contextual instead of universal like in the field of biology or physics.</li>
<li>By nature, HCI research is like nomads chasing water and grasslands, making it challenging for the community to accumulate knowledge.</li>
<li>Therefore, current HCI research is lacking motor themes and will also lack motor themes in the near future.</li></ol>
