The radius is the intensity of the earthquake.  Using a 3D camera as an input device I can move my hand left and right I move through time.  This highlights in magenta the earthquakes nearest to the current time.  When I close my hand I can rotate and zoom the earthquake points.<\/p>\n<p>\n\t\t\t\t\t\t\t<P><br \/>\n\t\t\t\t\t\t\t<iframe width=\"720\" height=\"455\" src=\"http:\/\/www.youtube.com\/embed\/2zl9tPkjfak\" frameborder=\"0\" allowfullscreen><\/iframe><\/p>\n<p>\n\t\t\t\t\t\t\tOne of the really interesting things you can see in this style of interaction is that we are using quite a natural grab and drag interaction when you want to manipulate the camera.  While moving your hand with your fingers relaxed allows you to navigate the temporal space.<\/p>\n<p>\n\t\t\t\t\t\t\tHaving that natural control of the 3D space turns out to be important as visualising the depth of the strike would have required using a different visual trick (like opacity) &#8211; yet with the fluid rotation provided by the gesture the human brain is easily able to establish the deep versus shallow earthquakes.<\/p>\n<p>\n\t\t\t\t\t\t\tIt would be interesting to provide the ability to dynamically change the use of the &#8216;spatial axis&#8217; where the user could gesture up and down through a series of options such as position, relative size, time, depth etc to hunt for patterns in the way the data is organised.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Using your hand to visualise earthquake data in 3D Using UMAJIN here we can see earthquake strikes in x\/y location [&hellip;]<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[40],"tags":[3,16,18,22],"class_list":["post-226","post","type-post","status-publish","format-standard","hentry","category-umaijn","tag-umajin","tag-3d","tag-perceptual-computing","tag-earthquake"],"_links":{"self":[{"href":"https:\/\/davidbrebner.com\/index.php?rest_route=\/wp\/v2\/posts\/226","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/davidbrebner.com\/index.php?rest_route=\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/davidbrebner.com\/index.php?rest_route=\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/davidbrebner.com\/index.php?rest_route=\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/davidbrebner.com\/index.php?rest_route=%2Fwp%2Fv2%2Fcomments&post=226"}],"version-history":[{"count":4,"href":"https:\/\/davidbrebner.com\/index.php?rest_route=\/wp\/v2\/posts\/226\/revisions"}],"predecessor-version":[{"id":489,"href":"https:\/\/davidbrebner.com\/index.php?rest_route=\/wp\/v2\/posts\/226\/revisions\/489"}],"wp:attachment":[{"href":"https:\/\/davidbrebner.com\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=226"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/davidbrebner.com\/index.php?rest_route=%2Fwp%2Fv2%2Fcategories&post=226"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/davidbrebner.com\/index.php?rest_route=%2Fwp%2Fv2%2Ftags&post=226"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
