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 method for generating an integrated circuit (IC) is provided wherein signal delays are transferable across two synthesis libraries where each library is associated with a different IC fabrication process. The method initiates with describing an IC design through a hardware description language (HDL). The method includes identifying logic signal delay points within the HDL. Then, technology-independent logic signal delay code is inserted within the delay points of the HDL representation. A system for designing an IC is also provided.

Method and apparatus for generating technology independent delays

A graphics controller providing flexible access to a graphics display device by a host. The controller includes an input bus for coupling to an output bus of the host, an output bus for coupling to the input bus of the graphics display device, a video processing circuit having an input coupled to the input bus of the graphics controller and an output coupled to the output bus of the graphics controller, and a bypass switching circuit adapted to switchably couple the input bus of the graphics controller to the output bus of the graphics controller so as to bypass the video processing circuit.
