A “Concurrent Projector-Camera” uses an image projection device in combination with one or more cameras to enable various techniques that provide visually flicker-free projection of images or video, while real-time image or video capture is occurring in that same space. The Concurrent Projector-Camera provides this projection in a manner that eliminates video feedback into the real-time image or video capture. More specifically, the Concurrent Projector-Camera dynamically synchronizes a combination of projector lighting (or light-control points) on-state temporal compression in combination with on-state temporal shifting during each image frame projection to open a “capture time slot” for image capture during which no image is being projected. This capture time slot represents a tradeoff between image capture time and decreased brightness of the projected image. Examples of image projection devices include LED-LCD based projection devices, DLP-based projection devices using LED or laser illumination in combination with micromirror arrays, etc.

The invention relates to a control device (1) for automotive vehicle comprising:—a tactile surface (2) intended to detect a contact of a finger of a user, and—a haptic feedback module (4) configured to vibrate the tactile surface (2), characterized in that it comprises a drive unit (5) configured to drive the haptic feedback module (4) so as to generate a haptic feedback in response to a press on the tactile surface (2), the haptic feedback being composed:—of the repetition of at least two identical individual haptic patterns (M1, M2, M3 . . . Mn), generated successively, and—of a period with no haptic feedback (B1, B2), intercalated between two successive individual haptic patterns (M1, M2, M3 . . . Mn). The invention also relates to a method of control for the control of such a device.

An image display control device according to the present invention includes a display control unit, an obtaining unit, a drawing unit, a deleting unit, and an operating unit. The display control unit displays an image on a display device. The obtaining unit obtains contact position information or proximity position information of a drawing device, which is relative to a display area of the display device. The drawing unit generates a drawn image, compose a display image of an information processing apparatus with the drawn image, and displays the composite image on the display device. The deleting unit deletes the drawn image from the displayed image, and display on the display device. The operating unit operates the information processing apparatus. The drawing device switches and specifies a generation and deletion of the drawn image, and an operation of the information processing apparatus.

Examples are directed to detect screen contact using total internal reflection. One example involves detecting contact on a screen, the screen comprising total internal reflection of light; and determining, via at least one processor, a location of the contact on the screen based on a disturbance of the total internal reflection, the disturbance caused by the detected contact.

A system includes a sensor to capture multiple images of a portion of a first object illuminated by coherent illumination and a time of capture of each of the images; and a processor to compare two images of the multiple images to identify one or more touch points. Each touch point has a difference in value between the two images that is greater than a threshold. Upon determining a spatial shape formed by the identified touch points that corresponds to a pointing end of a pointing object, the system provides at least one of: i) a touch location of the pointing end relative to the first object, where the touch location is based on the spatial shape formed by the identified touch points, or ii) the time of capture of a second image of the two images that produced the spatial shape.

An example system includes a camera to capture an image of an object on a surface, and a projector unit, communicatively coupled to the camera, to project the image of the object on the surface. The camera simultaneously generates a first trigger to the projector unit to switch display modes and a second trigger to a lighting source to disable light being projected onto the surface in response to an instruction to initiate capture of the image of the object.

A projection display unit (1) includes a body (10) and an invisible light application unit (30). The body (10) includes a projection optical system and a detection optical system. The projection optical system projects an image onto a projection surface (110). The detection optical system acquires an imaging signal based on invisible light. The invisible light application unit (30) applies the invisible light along a surface in vicinity of the projection surface while being placed on a surface that is an extension of the projection surface. The body (10) is movable with respect to an output opening (31) of the invisible light application unit, and a position of the body is adjustable with respect to the projection surface.

The present seam visually suppresses a gap defined between two adjacent reflective surfaces. The seam comprises a strip of light propagating material and a plurality of lighting units. The strip of light propagating material defines a front surface, two side surfaces and a back surface. The side surfaces of the strip of light propagating material is adapted for being positioning in the gap defined between the adjacent reflective surfaces. The lighting units are positioned along the back surface of the strip of light propagating material and are adapted for propagating light in the strip of light propagating material. When light is propagated in the strip of light propagating material, the gap between the two adjacent reflective surfaces is visually suppressed.

An electromagnetic touch panel includes a total-reflection light guiding plate and a side frame surrounding the total-reflection light guiding plate. The side frame includes a first side frame, a second side frame opposite to the first side frame, a third side frame, and a fourth side frame opposite to the third side frame. The first side frame and the second side frame are respectively configured with a plurality of first infrared (IR) emitters and a plurality of first IR receivers, and the third side frame and the fourth side frame are respectively configured with a plurality of second IR emitters and a plurality of second IR receivers. Polarized directions of IR rays emitted from the first IR emitters and the second IR emitters are different.
