A Presentation Support System
Controlled by User's Body
Gestures using Kinect Devices
University of Aizu,
Our study is to develop a support system that PPT
slides can be controlled by the natural operation
easily, through body movement, such as postures
and gestures. We define several gestures to
operate the PPT, use Kinect to detect the gestures,
and control the PPT slides based on the detected
gestures and corresponding definition.
Compared with PPT operations by mouse,
keyboard, and pointer, presentation can be smarter
and smoother with the support tool of the study,
since vivid presentation using both hands is

The system realized the
function of sending back of the
slide, although the accuracy is
little lower than controlling by
The research is important because it
enables the presenter hand free during
a presentation. It is also possible to
realize a variety of functions by adding
the other operation.
