ShadowReaching: New Perspective on Wall Display Interaction

We introduce Shadow Reaching, an interaction technique
that makes use of a perspective projection applied to a
shadow representation of a user. The technique was designed
to facilitate manipulation over large distances and
enhance understanding in collaborative settings. We describe
three prototype implementations that illustrate the
technique, examining the advantages of using shadows as
an interaction metaphor to support single users and groups
of collaborating users. Using these prototypes as a design
probe, we discuss how the three components of the technique
(sensing, modeling, and rendering) can be accomplished
with real (physical) or computed (virtual) shadows,
and the benefits and drawbacks of each approach.

track any extension that has the most movement like a dog following shadows easy to control. with a shadow for calabration and a dot for motion. add to my comment

We supply parts needed for multi touch screen you see here, for example our rear projection films only start at 80USD per meter square.

come to our channel and see

nice! ;)

A large screen would be wanted by anybody with a lot of information to look at. For example somebody making a presentation to a large crowd, such as a lecturer to a class of 200 people.

yup, it was really working. The user is holding a device consisting of a button (for clicks) and a position tracker. The cursors jump around a bit because the tracking system was running on buggy firmware (since fixed)

who would have a touch screen too tall for the user to reach the top.

was the shadow reaching really working? pretty cool if it was...and not just someone on a mouse behind you moving the green dot =)
