Apparatuses and methods are provided for determining whether a user intends to provide an input using an image of a control appearing on a surface. An apparatus may include first and second cameras to capture set and second sets of two or more images of the surface, and a unit to determine whether various conditions are true. A first condition is that a particular number of skin-color pixels are present within one cell of the two or more images. A cell location substantially coincides with the image of the control. A second condition is that the skin-color pixels persist for at least a particular time period. A third condition is that a region of skin-color pixels has a substantially rectangular shape. A fourth condition is that corresponding edges of skin-color pixels in the first and second sets of images are within a predefined offset distance. Additional conditions are disclosed.

Detecting user input provided to a projected user interface

A calibration image including dots and scale points is projected at first and second display surfaces. A location of a scale point may be modified. A location for a registration point is determined and the registration point is added to the calibration image. The projected calibration image is captured. A location of the captured registration point and locations captured scale points are identified. Captured dots that are projected onto the first display surface and their locations are identified. Each of the captured dots identified as being projected onto the first display surface are mapped to a corresponding dot of the calibration image. Dots of the calibration image that are not projected onto the first display surface are identified, locations of each of the identified dots are determined, and a synthetic dot is added to the captured image for each identified dot. The captured image may be provided as input to a process for determining one or more inverse offsets.

Method and apparatus for calibrating a projector for image warping

The present invention is directed to a method and system to render an image that impinges upon a non-planar surface to attenuate, if not abrogate, distortions introduced by the surface that features mapping the image as a plurality of spaced-apart planar cells to coordinates of the non-planar surface to produce a plurality of the inverted planar cells, with each of the cells including multiple pixels of the image, minimizing a distance between the cells while minimizing a change in the distance of each of the plurality of cells with respect to the surface coordinates; and impinging the plurality of planar cells upon the non-planar surface.

Method and apparatus for rendering an image impinging upon a non-planar surface

A method for adjusting an image projected onto a warped surface is provided. The method initiates with capturing calibration points within a calibration image projected onto the warped surface. The method includes analyzing the calibration points to determine relative locations among the calibration points. In one embodiment, the method utilizes a pseudo origin for locating beginning points for successive rows of calibration points. The calibration points are ordered according to the relative locations. The ordered calibration points may be applied to alter the image data prior to projection of the image data onto the warped surface. A system for calibrating points so that an image projected onto a warped surface does not appear as distorted is also provided.

Calibration technique for heads up display system

A method for debugging including the steps of receiving code having a software breakpoint function therein, running the code for the purpose of debugging, monitoring the code to detect the presence of the software breakpoint function, recognizing the software breakpoint function, determining an action to be performed based on the software breakpoint function, and implementing the action. The present invention also includes an apparatus for implementing the method for debugging and a medium embodying a program of instructions for execution by a device to perform the method for debugging.
