摘要： The universal input device provides a common user interface for a variety of different computing platforms including printed documents. Using the present system, one may use the universal input device to control various computing devices as well as capture handwritten electronic ink and have the electronic ink be associated with new or stored documents. The universal input device can be identified by a specific identification in order to allow for multiple users to operate on a document and/or within an application program simultaneously or not. An off-set optical system with infrared illumination handles perspective and helps detect positional encoding which can be covered by existing ink under common visible light illumination.

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： Interactive multi-view video presents a new type of video capture system. Many video cameras are allocated to capture an event from various related locations and directions. The captured videos are compressed in control PCs and are sent to a server in real-time. The compressed video can also be transcoded through an off-line compression approach to further reduce the data amount. Users can subscribe to a new type of service that allows users to connect to the servers and receive multi-view videos interactively.

A charging device as described herein can utilize a sensor-integrated resonating circuit with automatic frequency control to provide low-cost inductive charging functionality for electronic devices. As further described herein, a device to be charged can be equipped with a power receiver operable to receive power from the charging device via electromagnetic induction. The power receiver can additionally be utilized for initiation of charging such that charging for a device commences upon its associated power receiver being brought within range of an inductive charging surface at the charging device. Further, a charging device as described herein can have an inductive charging surface as well as a non-charging surface for providing other services such as information display. A charging device can integrate with an external information source to obtain items to be displayed at a non-charging surface thereon.

摘要： At least one image captured from a printed document and at least one image captured from a display surface other than a printed document are processed. A surface-type-identification module accepts as input both types of images and identifies, for a particular image, the type of surface from which the image was captured. A display-surface-preprocessing module preprocesses the at least one embedded-interaction-code image captured from a display surface other than a printed document. A printed-document-preprocessing module preprocesses the at least one embedded-interaction-code images captured from a printed document. An embedded-interaction-code-processing module outputs location information for at least one of the at least one image captured from a printed document and the at least one image captured from a display surface other than a printed document.

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.
