A system filters received messages (e.g., unsolicited advertisements) to determine if they are appropriate for a user based on the non-static, constantly evolving, context of the user. The system can track the user's context by monitoring various environmental parameters, such as related to the user's physical, mental, computing and data environments, and can model the current context of the user based at least in part on the monitoring. The system selects a set of one or more filters to apply to incoming messages based on the user's context, and the selected filters can be updated as the user's context changes. Messages that survive the filters are then evaluated against the user's context to determine whether they should be presented immediately or stored for delayed presentation.

Head-worn adaptive display

An eyepiece includes a mechanical frame adapted to secure a lens and an image source facility above the lens. The image source facility includes an LED, a planar illumination facility and a reflective display. The planar illumination facility converts a light beam from the LED received on a side of the planar illumination facility into a top emitting planar light source, uniformly illuminates the reflective display, and is substantially transmissive to allow reflected light to pass through towards a beam splitter. The beam splitter is positioned to receive the image light and to reflect a portion onto a mirrored surface. The mirrored surface is positioned and shaped to reflect the image light into an eye of a user of the eyepiece thereby providing an image within a field of view, the mirrored surface further adapted to be partially transmissive within an area of image reflectance.

A system for computer-based storing of information about a current state so that later recall of the information can augment human memories. In particular, when information about a current event of interest is to be stored, a variety of current state information of different types (e.g., video, audio, and textual information) about the environment and about a user can be acquired via sensors and other input devices. The variety of state information can then be associated together as a group and stored for later retrieval. Other information can also be associated with the group, such as one or more recall tags that facilitate later retrieval of the group, or one or more annotations to provide contextual information when the other state information is later retrieved and presented to the user. When information about a past event is to be recalled, one or more identifying recall tags can be received that are used to identify one or more state information groups that match the identifying tags. Some or all of the previously-acquired state information for the identified state information groups can then be presented to the user on appropriate output devices. Other information, such as annotations, can also be presented to the user in order to describe the state information and thus assist the user's recollection of the previous state when the information was stored.

Storing and recalling information to augment human memories

The present disclosure pertains to an image-processing device and method that make it possible to suppress block noise. A βLUT_input calculator and a clip processor determine βLUT_input, which is a value inputted to an existing-β generator and an expanded-β generator. When the value of βLUT_input qp from the clip processor is 51 or less, the existing-β generator determines β using a LUT conforming to the HVEC standard, and supplies same to a filter process determination unit. When the value of βLUT_input qp from the clip processor is larger than 51, the expanded-β generator determines the expanded β and supplies same to the filter process determination part. This disclosure, for example, can be applied to an image processing device.

PROBLEM TO BE SOLVED: To provide a video display device which provides a video image by superposing it on an image in an external world and by which observation of the video image is easy and it is hard to cause fatigue of eyes without depending on brightness of the external world. SOLUTION: The video display device (3) is provided with: a liquid crystal display element (11) which displays the video image; a light source (12) which provides the display element (11) with illumination light; a half mirror (15) which superposes video light (L1) from the display element (11) on light (L2) from the external world to guide it to the eyes (E); a liquid crystal shutter (16) which attenuates light from the external world; a control part (21) which controls emission luminance of the light source (12); a control part (22) which controls transmission of the shutter (16); a detection part (26) which detects luminance of the external world; and an interlocking control part (23) which controls the control parts (21, 22) according to a detection result of the detection part (26) to adjust the luminance of the video image to be provided and the image of the external world. The interlocking control part (23) makes difference between the luminance of the video image and the luminance of the image of the external world be always fixed without depending on the luminance of the external world.

Video display device

A camera with an automatic focusing device has an objective lens mounted on a camera. An image formed by the objective lens is divided into a plurality of zones. In each zone, a brightness distribution is obtained so as to detect a rough focusing condition in each zone, thereby producing a plurality of rough focusing condition data. Based on the result of the rough focusing condition data, one zone is selected. Furthermore, a precise focusing condition is detected in the selected zone based on the light contained in the selected zone, so as produce a precise focusing condition data. Based on the precise focusing condition data obtained from the selected zone, the objective lens is driven to an infocus condition.

A focusing lens for adjusting the dioptric power in accordance with the user's dioptric power is provided in each of right and left lens barrels. When a main switch dial is set at a normal position, a microcomputer sets the focusing lens at a dioptric power of 0 by controlling a motor so that the focusing lens moves to a position corresponding to a dioptric power of 0.

A screen image observing device and method provides the sensations of virtual reality to the observer and reduces, to the extent possible, the discrepancy that is perceived by the observer between the movement of the observer's head and the displayed screen image. The device has a head tracking means, which detects the movement of the observer's head, and a screen image generating means, which generates image data based upon the result of the detection performed by the head tracking means. Image data is supplied to a display means.
