Circular Image Selector
For a recent web project I've have been looking into a intuitive
solution to let people select an image from a huge set. Our goal
is to create an image selector that let users select an image for
a grid based poster. We tried using a rectangular widget with a
horizontal scrollbar that can be used to navigate through all the
images; just like the current Flickr image selector. The user can
drag an image from the list and drop it onto a droppable area in
the post (which is visualized in the web app). The image below
shows this rectangular image selector:
The good thing about this selector is that the user has a good
idea of where he is in the collection due to the visual cue of
the scrollbar and the know. He can quickly jump to a particular
section in the set by clicking on the bar. The downside about
this is that it decoupled the action and the goal (both
phychologically and spacially): the user had to drag and drop the
image to the droppables. Also, the amount of visible photos is
limited. A solution to this was using a list with multiple rows
as shown in the image below.
Although this vertical list works a lot better, we still had the
issue that the image selection used drag and drop which can be a
good solution though we didn't find this solution a fun way to
fill a grid-like poster with images. After some thinking and
brainstorming, my colleague pointed me to a jQuery class which
creates circular numeric sliders. This gave us the idea of
creating a circular slider as shown in the image below:
We implemented the idea with jQuery and it gives us a fun, quick
and intuitive solution to select an image from a huge set. We
started with only the inner circular slider without the ring of
images on the outside. Though this didn't work well because the
user does not have a hint of where he is in the total set.
Besides this ring we added a small line (in green below) around
the center image to show the user where he the selected location
is found in the complete set.
