The plaque

For the AR application to work, we could either use marker based or marker less tracking. Marker less would find and track a plane visible in the viewport to project the UI onto. While marker based would only project the UI onto a specific preprogrammed image. To provide additional context following feedback from one of the crits we reintroduced a marker and used it as an understanding aid for the user. This both provides additional information for the concept being illustrated, plus provides an extended user journey. Thus rather then having the AR UI fully self explanatory for the whole concept, the AR marker plaque provides some progressive disclosure.

The plaque is divided into three portions. The first being some simple copy to describe the concept. Second, this copy aided by a simple illustration to tie it to the AR experience. And thirdly, a small instruction to guide the user from the plaque to the AR app.

This was my first attempt. AR markers, like QR codes tend to hand distinct darker patches in the four corners, thus I followed this pattern. Plus, Will showed me an AR app on his phone that does not track to a specific marker, but to any surface and worker very well with a cutting mat with a strongly contrasting white grid on top. A warped grid is also used to illustrated the concept of space-time where they are bonded together.

The main content is divided in three, with some copy I tried to simplify while staying true to the concept, an illustration to help aid the copy and a small CTA effectively to guide the user to the app AR experience.

Throughout there has been a constant play with the sliding scale of accuracy. If we were to visualise this concept accurately with any objects relatable to any given audience, the effect would be so small as to be imperceivable, rendering it useless. In this latest turn we thought we could abstract the whole UI away from any sense of accuracy, to purely present the principle. Simply the sense of changes in one factor influence another. Rather than just skewing the data for the same audience, we thought we would change the audience to force us to explain this concept as simply as possible, then, maybe we could communicate this to successfully to a broader audience. This did not work.

The Vuforia developer kit provides a star rating system for markers users upload. The previous thee only got 1 out of 5 stars. This next one got wapping 3. I assumed that a greater star rating would make the UI less flickery and more stable attached to the marker, but at appears the star rating only applies to the recognisability for Vuforia to identify it.

Will thought it best we drop the grid pattern from the marker. We still needed a distinctive image for the app. I experimented with a few new layout options and adding space related elements. In the end I stuck with some additional stars. Dis not bode well with my partner, another scrapped idea.

During this time we also negotiated various objects to have in the UI. These ranges form black holes, to a single space man. We needed something that the user could relate to, something that Alistair Mcclymont made clear in a previous class. As of now we have the earth and a space shuttle, reflected in the marker above.
