摘要: A graphical representation (302) representing at least a portion of an observable three-dimensional space is presented. user can select location (314) on the to direct moveable item (136) within corresponding selected by user. Calibration operations be performed, and error correction information generated avoid mechanical error. Manipulation devices using non-orthogonal coordinate systems supported. Multiple items positioned specimen viewed under microscope (110), such as electrode living biological specimen.
