METHOD FOR FINE-TUNING THE PHYSICAL POSITION AND ORIENTATION ON AN ELECTRONIC DEVICE

摘要

An electronic data device programmed with a position and orientation calibration and adjustment program to visually display a two- or three-dimensional virtual representation of a user-selected physical space on the electronic visual display and to display a position indicator corresponding to an estimated initial location and orientation of the electronic data device in the user-selected physical space, and thereafter when a user makes a manual adjustment to the indicated location, the program causes the electronic data device to automatically adjust and correct the indicated location.

1. A method of fine-tuning the indication of the physical location and orientation of an electronic data device in a physical space, comprising:
(a) providing an electronic data device having a core processor, permanent memory for storing a program, temporary memory for loading and running a computer-executable program, means to load a computer-executable program onto the electronic data device, an electronic visual display, a visual display subsystem, at least one user input means for interacting with a computer-executable program, and a motion and/or rotation detection subsystem; (b) moving the electronic data device in a physical space; (c) loading a position and orientation calibration program with a device drawing coordinate system onto the electronic data device, which, when executed by the electronic data device, causes the device to visually display a two- or three-dimensional virtual representation of a physical space on the electronic visual display and an estimated initial location and orientation of the electronic data device in the physical space, and thereafter to update and correct the location according to user inputs; (d) initiating execution of the position and orientation calibration program; (e) defining an initial location point in the electronic device drawing coordinate system corresponding to the estimated initial location and orientation; (f) displaying on the electronic visual display a visual position indicator to indicate the initially estimated location and orientation; and (g) manually adjusting the placement of the position indicator on the device display to correct any observed inaccurate representation of the electronic data device physical location; wherein the position and orientation calibration program calculates an offset in drawing coordinates between the initial and corrected position points, and executes one or more transformations to determine the corresponding physical coordinates as well as the offset between the initially estimated location and orientation and the physical coordinates of the corrected location.
