The aim of this thesis is to create a functional application for the Android environment that allows the user to do simple virtual drawings without the use of the touch screen, but rather through hand motions caught by the camera.
There is a variety of approaches to this end, which vary by complexity and performance. This piece of work attempts to find a middle ground among the existing algorithms, as well as to build on and improve them specifically for this particular task. The idea is based in sci-fi books and movies, as well as the current global trend and human desire to simplify their work with the help of virtual reality. This type of technology, in conjunction with augmented reality, could be used in a variety of fields, such as architecture, for easier real life model sketching, internal design, for virtual showcasing of furniture inside a room, etc. A similar technology could be used in the future for hologram manipulation.
The application was entirely created in the Eclipse IDE with the Android SDK and the OpenCV library. It can be run on smartphones running Android version 4.2.2 or newer.
