Abstract
Believable 3D animation of walking or running characters still requires complex motion capture technology or
extensive skills in manual keyframing. We present an inexpensive, yet natural input method: The user “walks” on
a digital graphics tablet, striding over the surface with two pens in his or her hands, where each pen represents
one leg. This technique leverages the popular graphics tablets that can track two drawing tools at the same time.
We implemented recording software and a plug-in to use the data in off-the-shelf 3D animation software.

1. Introduction
The input of gait animation is notoriously difficult, due to its
complexity and the sensitivity of human perception concerning
implausible motion. Character animators rely on a huge
amount of expertise and on motion capture methods, which
often are expensive and require lots of space and setup. The
method presented here is based on a digital graphics tablet
that can track two tools at the…
