Yesterday I put the finishing touches into my latest article, Motion capture-aided mobile user interface analysis. Those interested can view and download the document.
Motion capture nodes on a Nokia N95
In the course of the past year, I researched the viability of using a motion capture lab for performing user interface analysis.
My method relies on recording motion capture data synchronously with the device's video and accelerometer stream using a on-board application for Symbian. With a OpenCV-based application, the motion capture data can then be projected onto the video after camera calibration. This allows for analysis of the sensory information, using the motion capture data as a ground truth.
This technique has significant benefits over conventional computer vision techniques, and is elaborated in the article.
I'll put the source code of the various applications online after improving the documentation in the coming weeks.
