Progress Report I – AR for Participation with Outdoor Art

By on March 11th, 2013

Brief overview:

We are running a bit behind schedule due to certain issues revealed in prototyping, requiring us to try out different alternatives as opposed to our initial plans. As we see it,  should not affect the overall deliverable time-schedule, but we might have to rethink the user interaction so as to provide a best-possible experience in line with technical considerations.

Tasks laid out: 

  1. Prototype/explore registration issues, gather media, begin IRB approval process for User Studies.
  2. Registration of images in lab setting (backend, client side code, image placement). Meet with stake-holders for interaction ideation and wants/needs analysis, level of detail viewing.

Tasks completed: 

  1. Prototype/explore registration issues, gather media.
  2. Registration of images in lab setting. Meet with stake-holders for interaction ideation and wants/needs analysis, level of detail viewing .

Prototypes: http://cc.gatech.edu/~msati3/argon/multiMarkers/basic.html (multiple image markers simultaneous tracking) and http://cc.gatech.edu/~msati3/argon/frameMarkerTransform/index.html (explorations into using the rotation angles of the phone to determine viewing frustum in case of absence of frame-markers). As things stand, we believe we will be able to get the desired interaction we want using a multi-image target, as demonstrated by the prototype @ http://cc.gatech.edu/~msati3/argon/multiImage/basic1.html. Initial mural media @ https://www.dropbox.com/sh/epslvenxgcm4xip/HSodB1c-tP. Initial sync up with people involved scheduled.

Tasks not completed/still in progress:

IRB approval – pushed back till prototyping complete.

Risks update:

1.   Prototyping has informed us that the primary risk is figuring a way to track a large image target, which might not be completely in view all the time. We have approached this problem via subdivion of the target, sensor fusion, and presently, using a single multi-image target. We need to nail this work-item before proceeding.
