Transparency and imaginary colors.
Unlike the Metelli monochrome transparencies, when overlays and their backgrounds have chromatic content, the inferred surface colors may not always be physically realizable, and are in some sense "imaginary." In these cases, the inferred chromatic transmittance or reflectance of the overlay lies outside the RGB spectral boundaries. Using the classical Metelli configuration, we demonstrate this...

متن کاملSpectral reflectance and transmittance prediction model for stacked transparency and paper both printed with halftone colors.
When a transparency printed with a first halftone color is deposited on top of a paper printed with a second halftone color, we obtain a third color that we are able to predict in both reflectance and transmittance modes, thanks to a spectral prediction model. The model accounts for the multiple reflections of light between the printed paper and the printed transparency, which are themselves de...
متن کاملImaginary Devices
We propose Imaginary Devices, a set of freehand gestures that mimic the use of physical input devices. Imaginary Devices allow users to choose the input modality best suited for the task at hand, such as a steering wheel for a driving game or a joystick for a flight simulator. Exploiting the skills that users have acquired using physical input devices, they can instantly begin interacting with ...
متن کاملImaginary Worlds
Leaders today seem to be suffering from what might be called a failure of the imagination. We seem to be continually finding ourselves in situations where the leaders say something like “no one could have imagined that this would happen.” For example: Who could imagined that Hurricane Katrina would breach the levies in New Orleans; who could have imagined that an insurgency would arise from the...
