Abstract: Smartphone AR presentations with automatic camera tracking [DE]
Emre Yalcinkaya, Smartphone AR presentations with automatic camera tracking, Hochschule Düsseldorf, Bachelor thesis, 28.11.2024.
This thesis describes and explores implementation concepts of combining automatic camera
controls and augmented reality with the help of a smartphone for the purpose of giving
lectures and presentations as a one-man show. It is assessed how augmented reality systems
compare to rather traditional methods of giving presentations with conventional presentation
software. To realize this a concrete system has been developed which can be operated by just
the one user alone. A smartphone that is running an AR application is attached to a gimbal
or a motorized smartphone holder and keeps via an automatic person tracking algorithm a
person or an AR object in frame. The AR application is used for loading and displaying
virtual presentation slides and 3D objects. The user can additionally pre-plan camera angles
for every presentation slide or save preferred angles to a remote control. A framing algorithm
is responsible for finding a fitting image composition. Finally the image output can be
recorded and shared over common video conference software. As an alternative the usage of
a PTZ-camera and a computer is being considered. The system is evaluated qualitatively
using expert interviews regarding its performance and how it stands out in comparison to
traditional presentation methods.
