Instrumentation and algorithms for electrostatic inverse problems

Thesis (M. Eng.)--Massachusetts Institute of Technology, Dept. of Electrical Engineering and Computer Science; and, (S.B.)--Massachusetts Institute of Technology, Dept. of Physics, 2001.Includes bibliographical references (leaf 89).This thesis describes tracking objects with low-level electric fields. A physical model is presented that describes the important interactions and the required mathematical inversions. Sophisticated hardware used to perform the measurements is described in detail. Finally, a discussion of the myriad applications for electric field sensing is described. The main application goal for this thesis is to make an efficient 3D mouse using electric field sensing technology.by John Paul Strachan.S.B.M.Eng
