Design of the 3D Input Method Based on Touch Device for Mobile

This thesis describes the technology to express 3D gesture as an input from common 2-dimension touch input panel without additional hardware development or change to provide near real 3D UI and algorithm to implement such technology. It introduces how 3D user interface has become the major issues among the major mobile vendors and briefly describes existing touch devices which can be divided into resistive and capacitive touch panels. It also introduces Open GLES which takes a major role in graphical presentation of 3D user interface. Algorithm to achieve the 3D gesture in 2D space is presented at last.
