A plurality of algorithms for interpreting and displaying point cloud data are disclosed. Typically, a virtual grid is constructed over point cloud data, with intersections of the grid at a predetermined spacing that may be dependent on density of the point cloud. Several methods are implemented that utilize tuple data from tuples near a respective intersection to populate intersections of the grid with data. In most embodiments, the intersections of the grid correspond to pixels in a raster image. The tuple data may be manipulated to determine Nyquist spacing of points in a point cloud and portions thereof, develop monoscopic and stereoscopic images, and enhance selected features of an image. Additional algorithms are disclosed that reduce storage and computational requirements during processing of point clouds. Such algorithms use a tiled grid structure wherein processing and data storage proceeds in one or a few of the tiles at a time.

A tactile feedback switching mechanism having a plurality of switching states. The tactile feedback switching mechanism includes a plunger switch having a plunger. When the plunger is displaced a given distance the switch changes state. A covering lies at least over the plunger switch and includes a border section and a deformation section. The covering may be formed from an elastic material such as an elastomer. When a user depresses the plunger, confirmation of a change in the state of the switch can be tacitly sensed by a change in resistance provided by the covering. The resistance of the covering changes by deformation of the deformation portion of the covering while the plunger is depressed.
