This contribution deals with preliminary studies for touchless interaction based on capacitive sensor technologies. An existing approach in combination with additional capacitance measurements is used for position estimation. For that a measurement system is utilized which is able to measure capacitances in a range of a few fF to several pF. The main focus is the 3D position estimation of a human finger through spatial capacitance distributions caused by its movements. A grounded metallic test object is used as an abstract model of a finger. The capacitance modeling is based on a 2D simplification by considering properties of symmetry. This new model, combined with complex data processing algorithms, should ensure precise finger gesture recognition in future research.
