In the optical member, a Signal/Noise ratio is high which is a ratio of a reflectance of the wavelength selective reflection portion to a reflectance of the underlayer in a wavelength range where the wavelength selective reflection portion has wavelength selective reflecting properties.

The optical member of the present invention includes: a substrate; and a dot that is in contact with a surface of the substrate, in which the dot has wavelength selective reflecting properties, the dot is formed of a liquid crystal material having a cholesteric structure, the cholesteric structure has a stripe pattern including bright portions and dark portions in a cross-sectional view of the dot when observed with a scanning electron microscope, the dot includes a portion having a height which continuously increases to a maximum height in a direction moving from an end portion of the dot to the center of the dot, in the portion, an angle between a normal line perpendicular to a line, which is firmed using a first dark portion from a surface of the dot, and the surface is in a range of 70° to 90°, and the liquid crystal material includes a surfactant.

Disclosed are an infrared touch screen bezel for installing a functional assembly and a display terminal including the same. The infrared touch screen bezel (10) includes a frame body (11), a first infrared base panel (12), and a second infrared base panel (13); the first infrared base panel (12) and the second infrared base panel (13) are both arranged in a cavity (101) of the frame body (11), and a functional assembly (30) is arranged in a gap between the first infrared base panel (12) and the second infrared base panel (13); the first infrared base panel (12) and the second infrared base panel (13) are electrically connected through a first flexible circuit board (14). The above-mentioned infrared touch screen bezel (10) may greatly reduce the width of the frame required to install a functional assembly without affecting the infrared touch function.

A touch field is created around a touchscreen display, the field is in front of a touch surface of the display and the field maps to locations on the display. An operator of a terminal during a transaction is presented with transaction interface screens that are visually rendered on the display. The operator makes interface options selections, performs screen navigation, and provides date entry field inputs by placing the operator's hand within the field without touching the touch surface of the display and making hand poses, hand movements, and/or hand gestures. The poses, movements, and/or gestures are translated into touch actions and touch inputs recognized by the transaction interface and processed as operator-provided input during the transaction.

A stereoscopic display device comprising: a stereoscopic display unit; a space sensor; a determination unit for determining whether the instruction position detected by the space sensor is within a detection area corresponding to the instruction stereoscopic image, and accepting an instruction corresponding to the instruction stereoscopic image; a disparity amount decision unit for deciding a disparity amount between the instruction left-eye image and the instruction right-eye image displayed by the stereoscopic display unit, and decreasing the disparity amount between the instruction left-eye image and the instruction right-eye image according to a decrease in the interval detected by the space sensor; and an image processing unit for displaying the instruction stereoscopic image on the stereoscopic display unit by the disparity amount decided by the disparity amount decision unit.

According to an illustrative embodiment, an information processing apparatus is provided. The apparatus is used for processing a first image projected toward a target. The apparatus includes a processing unit for detecting that an object exists between a projector unit and the target, wherein when an object exists between the projector unit and the target, the apparatus determines an area of the object and generates a modified first image, based on the area of the object, for projection toward the target.

The present application discloses systems and methods for a virtual input device. In one example, the virtual input device includes a projector and a camera. The projector projects a pattern onto a surface. The camera captures images that can be interpreted by a processor to determine actions. The projector may be mounted on an arm of a pair of eyeglasses and the camera may be mounted on an opposite arm of the eyeglasses. A pattern for a virtual input device can be projected onto a “display hand” of a user, and the camera may be able to detect when the user uses an opposite hand to select items of the virtual input device. In another example, the camera may detect when the display hand is moving and interpret display hand movements as inputs to the virtual input device, and/or realign the projection onto the moving display hand.

There is provided a displacement detection device including a light source, an image sensor and a processing unit. The light source provides light to a finger with a light source parameter. The image sensor receives reflected light from the finger, outputs valid images when the light source is being turned on and outputs dark images when the light source is being turned off. The processing unit determines a contact status according to one of the dark images and one of the valid images, and calculates a displacement according to two of the valid images to accordingly adjust the light source parameter.

This disclosure relates to an interactive display, having a front surface including a viewing area, and providing an input/output interface for a user of an electronic device. A planar light guide (PLG) disposed substantially parallel to the front surface, has a periphery at least coextensive with the viewing area. A light-emitting source (LES), disposed outside the periphery of the PLG, is optically coupled with a PLG input. The PLG outputs reflected light, in a direction substantially orthogonal to the front surface, by reflecting light received from the LES. A light collecting device (LCD) collects scattered light that results from interaction of the reflected light with a user-controlled object. The LCD redirects the collected scattered light toward one or more light sensors. A processor recognizes, from outputs of the light sensors, an instance of a user gesture, and controls the interactive display and/or electronic device, responsive to the user gesture.
