摘要： An interactive display in which alternating illuminators are used to reduce or cancel specular reflections. The interactive display includes multiple illuminators and at least one camera placed behind one or more display layers. The interactive display uses a phase management mechanism that controls alternation of phases of the interactive display. When in the first phase, the first illuminator is controlled to dominate over the second illuminator. When in the second phase, the second illuminator is controlled to dominate over the first illuminator. A consolidated image is then formulated using a combination of the first and second images. The consolidated image has reduced or eliminated specular reflections as compared to the first and second images alone.

摘要： A method of interacting with a computing device via one or more inking instruments to generate digital ink may include the steps of emitting light from a light emitting device to an inking instrument, receiving first user inputs from the inking instrument, and identifying the inking instrument based on sensed light reflected from the inking instrument. Another method may include the steps of simultaneously detecting first user inputs from a first inking instrument and second user inputs from a second inking instrument by receiving first light emitted from the first inking instrument and second light emitted from a second inking instrument that each have one or more identifying characteristics, identifying the inking instrument based on their identifying characteristics, and generating corresponding digital ink. These methods may be implemented via computer-executable instructions and may be used with a horizontally-placed display, tablet-based laptop computers, and passive or active digital inking instruments.

摘要： A light pointer is selectively activated to direct a light beam onto an interactive display surface, forming a pattern of light that is detected by a light sensor disposed within an interactive display table. The waveband of the light produced by the light pointer is selected to correspond to a waveband to which the light sensor responds, enabling the light sensor to detect the position of the pattern on the interactive display surface, as well as characteristics that enable the location and orientation of the light pointer to be determined. Specifically, the shape and size of the pattern, and the intensity of light forming the pattern are detected by the light sensor and are processed to determine the orientation of the light pointer and its distance from the interactive display surface. The pattern may comprise various shapes, such as circles, arrows, and crosshairs.

摘要： Embodiments are disclosed that relate to the correction of an image acquired in a rolling image capture system for ambient light. One embodiment provides a device comprising a screen, a rolling image capture system, a local light source, and a controller. The controller is configured to operate the local light source while acquiring first and second frames of image data to integrate each field of image sensor pixels for a duration of local+ambient light and for a duration of ambient light such that a sum tlocal+ambient+tambient for the first frame is different than a sum tlocal+ambient+tambient for the second frame for each field of pixels. The controller is further configured to determine an ambient light value, and to adjust one or more pixels based upon the ambient light value.

摘要： The present disclosure provides for a computing system having virtual keyboard functionality that can be selectively enhanced through use of a tactile keyboard overlay. The tactile keyboard overlay includes a plurality of depressible key portions, and is placed onto an operative surface of a touch interactive display. The computing system configures the virtual keyboard functionality, so that each of the depressible key portions is operable to produce a touch input on the touch interactive display that causes performance of a corresponding input operation. The virtual keyboard functionality is dynamically and automatically located on the touch interactive display based on user placement of the tactile keyboard overlay.

摘要： The correction of an image for ambient light in an optical touch-sensitive device is disclosed. For example, one disclosed embodiment comprises integrating a first field of pixels in an image data frame for a different duration of ambient light exposure than a second field of pixels in the image data frame. Intensity data is read from the first field of pixels and the second field of pixels, and an ambient light value is determined for one or more pixels in the image data frame from the intensity data. The ambient light value then is used to adjusting one or more pixels of the data frame for ambient light.

摘要： The determination of an apparent distance between an object and a surface is disclosed. One disclosed embodiment comprises illuminating the object with a spatially inhomogeneous irradiance from the surface, an intensity variation in the spatially inhomogeneous irradiance in a plane parallel to the surface responsive to a distance between the plane and the surface. Next, an image of the object is acquired while the object is illuminated by the spatially inhomogeneous irradiance, and the apparent distance of the object from the surface is determined based on a brightness contrast in the image of the object due to the spatially inhomogeneous irradiance.
