Interaction technologies for mobile devices became an important
research sector, over the past years. A great number of inspiring
work concerning different concepts and investigations about the
humans abilities to interact has been done.
mobile interfaces are still based upon input technologies, which have
been established for desktop scenarios. Pointing on touchscreens
and performing input on keyboards demand the user’s attention, yet
only represent secondary tasks in mobile scenarios. People being on
the go desire to fulfil a primary task, such as getting to the office or
relaxing in the park. Hence the Distraction caused by mobile devices
is unneeded and sometimes even dangerous.
This system proposes
thumb on hand gestures for interacting with mobile devices. Our
concept address the following contradictory need. The user’s hand
should be exempted from a physical device. At the same time we
want to enable the user to have his device "at hand" at all times.
Our main focus was to implement
rich input options generated from the thumb interplaying with the
corresponding hand. We suggest gestures like pinching fingers or
moving the thumb across the palm as appropriate for quick interactions
in mobile scenarios and present the corresponding realization
techniques. Our design involves a chest mounted camera system,
enabling the detection and analyse of the users hand as it is held in
front of the body. The tracking of the thumb’s position and motion in
reference to the users empty hand enables the possibility to control
imaginary widgets like sliders,dials or buttons placed along our
