Patent attributes
Disclosed herein is a point determination and projection device configured to automatically detect the location of a point of interest, such as a midpoint or other intermediate point on a surface, and to project light or another image onto such point of interest to indicate its location to a user. In accordance with certain aspects of an embodiment of the invention, the device includes remote distance measurement devices, such as laser distance measurement devices, that measure the distance to, for example, corners of a wall surface, and a digital protractor that measures the angle between the two remote distance measurement devices. Based on those measurements, a processor calculates the location of a predesignated point of interest, such as a midpoint or other intermediate point between the two wall corners, and projects a light or other image toward the location of such midpoint or other intermediate point to indicate such location to a user.
