摘要： An embedded interaction code-enabled display includes: an outer transparency layer, an optional inner transparency layer, an optional infrared-reflection layer between the outer transparency layer and the inner transparency layer, an EIC dot pattern between the outer transparency layer and the infrared-reflection layer, and, optionally, transparency glue between the outer transparency layer and the infrared-reflection layer or the inner transparency layer. The outer transparency layer 1308 and the inner transparency layer may be glass, plastic, or a film. The EIC dot pattern may be printed on, or pressed onto, the inner side of the outer transparency layer. The EIC dot pattern may include an encoded surface identifier that identifies the embedded interaction code-enabled display. The encoded surface identifier may uniquely identify the embedded interaction code-enabled display.

摘要： A method and system for decoding data on a medium that is captured by an input device is described. The method decodes a symbol design, such as an embedded interaction code (EIC), on a display screen, such as a liquid crystal display (LCD). An image that is captured by an input device, such as a universal pen-type input device with a camera, is received. The captured image is processed to output an extracted bit stream. Position data and/or metadata information is decoded from the extracted bit stream and a position of the captured image with respect to a screen of the LCD is determined based upon the decoded position data. The EIC pattern may be recognized from LCD pixel grids and a bit stream of EIC bits may be extracted based upon the recognized EIC pattern.

摘要： A method and system for presenting data on a medium for capture by an input device is described. The method embeds a symbol design, such as an embedded interaction code (EIC), in an image on a display screen, such as a liquid crystal display (LCD). A grid with a plurality of pixels defines a size of an EIC pattern on an LCD. An area of the grid is used to embed position data and/or metadata information. The area may be defined by a sub-pixel of the plurality of pixels and/or the edges of the grid itself. The sub-pixel with the EIC pattern may be configured to have a grey value based upon a color of an underlying image associated with an application program being displayed on the LCD. The method also allows for decoding of the position data and/or metadata information in the EIC pattern on the LCD.

摘要： Techniques for providing camera based code reading are disclosed. In some aspects, a camera-readable code is generated which may be read by a code reading device. The code reading device may capture an image of the code, process the image, and decode the code. The code includes symbols arranged to form a pattern. According to one or more embodiments, an image with the code is cropped to remove extraneous information. The code image is manipulated by exact binary segmentation to remove background information from the code. The code is oriented to a grid using an interval value defined between the symbols. The symbols are decoded by comparing unique aspects of the symbols using a statistical analysis. The decoded symbols may be converted to a message for a user or be used for other purposes.

摘要： Embodiments of the invention relate to decoding encoded barcode information from a series of camera-captured images by generating binarized sequences from the series of camera-captured images and decoding the encoded barcode information from the binarized sequences. A series of preprocessed images is generated from the series of camera-captured images by removing non-uniform illumination, reducing noise, and enhancing contrast between bars and spaces of the series of camera-captured images. Barcode-image orientations are estimated for the series of preprocessed images. The series of preprocessed images are projected along their respective barcode-image orientations to generate a series of gray-sequence images that represent barcode information in one dimension. The binarized sequences, each of which contains partial barcode information, are connected into a concatenated sequence according to computed shift information of neighboring binarized sequences.

摘要： The projection display includes a light projector unit for generating and projecting light, an oscillator unit for oscillating light projected from the light projector unit, and a frequency generation and modulation unit. The frequency generation and modulation unit drives the oscillator unit and modulates the light projected by the light projector unit. In turn, the oscillator unit oscillates the light projected by the light projector unit in two dimensions, so that the projected light scans an incident surface in a raster pattern. At the same time, the frequency generation and modulation unit modulates the light produced by the light projector unit in synchronization with the scanning process and image data supplied so that the projected light produces images corresponding to the image data over a scanned area.

摘要： A user interface and techniques for presenting content in a panel-based layout are described. The user interface has one or more demarcation bars to define multiple panels on a screen area. Different subject matter (e.g., data, content, programs, etc.) may be placed in the various panels. A bar navigation element facilitates navigation of the bar(s) among preset positions. With the bar navigation element, a user can intuitively resize the panels using just a single actuation (e.g., a single click of a mouse, or a stylus tap). The panels remain in their original orientation and relative positioning, and remain visible in the user interface so that the user can track their location.
