摘要:
A layer that assumes either opaque or transparent state depending on the applied voltage is utilized to secure printed matter. The layer may also require an electrical or optical switching signal to switch between the opaque and transparent states. The layer is provided above the document to be secured and is set to the opaque state so as to obscure the contents of the document. When a prescribed voltage is applied, the layer turns to its transparent state. However, the voltage can only be applied to the security layer in the presence of a security key. A recording system may be employed to log all key-enabled access to the document.

Described is a method and a system for providing user interaction with various devices that incorporates adaptable visual and haptic stimuli. Both the visual and tactile elements of this user interface are aligned with each other and are animated in such a way as to convey more information to the user of such a system than is possible with traditional user interfaces. An implementation of the inventive user interface device includes a flexible and/or stretchable two-dimensional (2D) display membrane covering a set of moving parts, forming a hybrid two-dimensional (2D) and three-dimensional (3D) user interface. The flexible display membrane provides detailed imagery, while the moving parts provide a low relief tactile information to the user. Both the detailed imagery and the low relief tactile information are coordinated together as to the timing, to enable a coordinated user interface experience for the user. Optionally, various sound affects may also be provided, in a time-synchronized manner with respect to the imagery and the tactile information.
摘要:
A multi-function device that prints information images onto sheets of photo-addressable media is described. The multi-function device is comprised of an image acquisition component, an image generation component, optional image transformation components and an image projector to illuminate the photo-addressable medium with the optionally transformed information images. The effects of ambient light on the photo-addressable medium are reduced by tuning the response characteristics of the photo-addressable medium to respond to the wavelength of the projected light and/or to interpose band-pass filters that reduce non-projected light incident on the photo-addressable medium. Programmable characteristics of the photo-addressable medium are adjustable to compensate for ambient light. Registration marks on the photo-addressable medium allow the alignment of the projected image with the photo-addressable medium. Additional optional image transformations are applied to adjust the size of the information image, increase clarity and the like.
摘要:
Described is a system and method for controlling the state and capabilities of a meeting room automatically based on the content being presented. The system can detect certain states (such as transitions to a demo, or question-and-answer sessions) based on content of slides, and can automatically switch displays and other devices in a meeting room to accommodate these new states.
摘要:
The system enables novice teachers to leverage the expertise of other more experienced teachers who are distributed across geographical areas covered by similar teaching standards (usually states). By leveraging the vast body of knowledge contained within their peer group, the system is designed to help teachers produce better lesson plans. This is accomplished by providing teachers with suggestions based other teachers' plans for similar lessons.
摘要:
A system and method for accessing content provided by a presenter during a presentation is described. The system and method includes a presentation module used by a presenter to display presentation materials to audience members during a presentation. Also included is a selection module that allows a display of a representation of the presentation materials that have been displayed. When activated, the selection module enables an audience member to select for redisplay by the presentation module a particular one of the presentation materials.
摘要:
A method and system for delivery of targeted advertisement via multifunction document imaging devices. Imaging devices used for copying, scanning, faxing and printing documents are used to deliver advertisements, coupons, and other promotional material to users. The imaging device is capable of delivering targeted promotional material based on analysis of the documents content passing through the device. Targeting is based on device history, user history or user demographics. Device history and user history are compiled from the contents of the documents processed respectively at a device and by a user. Demographics are inferred from a demographics model using user identity or document content input to the model. Advertisements may be delivered via paper, the device display, and other means.

摘要:
A system and method for determining a presence state of a person. A plurality of data feeds is received. A subset of the plurality of data feeds that includes data regarding presence states of a first person is identified. The subset of the plurality of data feeds are analyzed to determine a plurality of presence states of the first person, wherein a respective presence state of the first person is determined from a respective data feed in the subset of the plurality of data feeds. One or more presence states of the plurality of presence states are reported to subscribers via the network.
摘要:
A method and system for additively, manually sequentially or manually in parallel, selecting multiple points or regions of interest in the analog or digital viewfinder of a photo or video camera with automatic controls like auto-focusing, auto-metering and auto white-balancing. Points or regions capable of being selected, within a grid of elements comprising a camera's evaluative matrix and represented to the user in a viewfinder or other display, may be hard-coded (pre-defined, selectable regions) or any point, pixel, or group of pixels. Data from the selected regions is used to simultaneously, dynamically adjust focus related parameters, light metering and white balancing of the camera and is tied into these features. Point selection may be via touch screen or by holding down a lock button. The selected points or regions may be applied to focus and aperture related adjustments or for any other camera function related to measurement of the scene.
