Karsten Schmidt<p>Seeing <span class="h-card" translate="no"><a href="https://merveilles.town/@neauoire" class="u-url mention" rel="nofollow noopener" target="_blank">@<span>neauoire</span></a></span>'s paper computing explorations, I was reminded of an old idea I proposed at PaperCamp LDN back in 2009: Originally this was vaguely about using origami to create multi-purpose AR markers, but I then extended it to other use cases, some of which could be adapted and be even relevant today, e.g. as a form of proof-of-work, protection against AI crawlers or other form of access control.</p><p>Some possible approaches for different use cases:</p><p>1) Ask users to perform or series of simple folds and then check results by validating fold lines in the flat sheet paper via computer vision<br>2) Same as #1, but perform shape recognition/validation of fully folded result<br>3) Unfold a pre-shared (and pre-folded) origami object to check result by validating fold lines via computer vision<br>4) Provide instructions for multiple origami creations to create uniquely identifiable objects for computer vision based interactive environments</p><p>Number 1-3 are more or less about forms of proving physicality, work, membership. Number 4 is more about using origimi as fiducial markers for general interactions</p><p>More ideas/summary from that event:<br><a href="https://adactio.com/journal/1546" rel="nofollow noopener" translate="no" target="_blank"><span class="invisible">https://</span><span class="">adactio.com/journal/1546</span><span class="invisible"></span></a></p><p>cc/ <span class="h-card" translate="no"><a href="https://mastodon.social/@adactio" class="u-url mention" rel="nofollow noopener" target="_blank">@<span>adactio</span></a></span></p><p><a href="https://mastodon.thi.ng/tags/PaperCamp" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>PaperCamp</span></a> <a href="https://mastodon.thi.ng/tags/Origami" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>Origami</span></a> <a href="https://mastodon.thi.ng/tags/ComputerVision" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>ComputerVision</span></a> <a href="https://mastodon.thi.ng/tags/InteractionDesign" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>InteractionDesign</span></a></p>
