Wearable
Gestural Interface

What is WUW?


WUW is a wearable gestural interface
that projects information onto surfaces
or objects, and allows the user to
interact with the information through
different gestures and movements.
The system consists of a pocket
projector and small camera attached to
the users hat, color markers on the
users fingertips, and a laptop carried in
the users backpack.
The camera captures a video stream,
the software running on the laptop
processes the stream using simple
computer-vision techniques, and tracks
the color markers on the users
fingertips.
All of the information from the system
is displayed through the projector,
projected onto a wall or other surface
for the user to see.
What can WUW do?


The main purpose of this system is to allow the use of
gestural commands to interface with the system.
There are three main categories that WUW focuses on:

Gestures supported by multi-touch systems.
This category includes popular touch
commands like zooming with two fingers,
flipping through images with one finger, and
drawing using a finger as a pen.

Freehand gestures. These gestures include
creating a rectangle or frame shape with
both hands to activate a picture taking
application, and putting both hands together
palm to palm, which with navigate back to a
home page.

Iconic gestures, or in-the-air drawings. These
gestures are symbols drawn in the air that
the system can then recognize as
instructions.
WUW Applications

One application is an interactive maps app. A map is
displayed on a nearby surface by the projector, and the
user can interact with it with hand gestures that they are
familiar with, such as zooming in, zooming out and
panning the map.
Another application that WUW supports is a drawing app.
This allows the user to draw on any surface they want,
using their finger as a pen.
Another application is a camera/photo gallery. By making
a frame shape with their hands, the user can take pictures
without taking a camera out. The user can then project
their photo album onto a surface, and flicks through all
their photos.
There is an analog watch application also. If the user
draws a circle on their wrist, the system will project an
analog watch.
