An assembly for holding and controlling curvature of a glass plate for an optical touch sensitive system is described. The assembly comprising a first frame element extending in a first plane and configured to extend at least partially around a panel; at least one second frame element extending in a second plane and forming a support portion for the plate, and at least one spacing element positioned at least partially between the support portion and the first frame element. The spacing element us configured to control a curvature of the first frame element and wherein the at least one second frame element is configured to engage the plate at the support portion, is attached to the first frame element, and is tiltable, by controlling the curvature of the first frame element with said spacing element, to control a curvature of the plate.

A touch sensing apparatus is disclosed comprising a panel that defines a touch surface, a plurality of light emitters and detectors arranged along a perimeter of the panel. The light emitters are arranged to emit a respective beam of emitted light that travels above the touch surface, wherein the light detectors are arranged to receive detection light from the emitted light. The plurality of light emitters and detectors are arranged above the touch surface and are connected to a substrate extending in a direction parallel with a normal axis of a plane in which the panel extends. A method of assembling a touch sensing apparatus is also disclosed.

A projection video display device includes: a projection unit projecting a display video upon a projection surface; an image capture unit; detection units detecting the states of manipulation objects which carry out actions for the input manipulation; a manipulation instruction information generating unit, on the basis of the states of the manipulation objects which the detection units have detected, generating manipulation instruction information indicating a description of the input manipulation; and a communication unit connecting to the information processing device. The detection units detect movements of manipulation objects and attributes which represent the states of manipulation objects other than the movements. The manipulation instruction information generating unit generates, first control information for carrying out the pointer manipulation input upon the information processing device, and, on the basis of the attributes of the manipulation objects, second control information for carrying out a prescribed key input upon the information processing device.

A projection display unit includes, in a housing (120), a visible light illuminator, a light valve that modulates a first polarized component included in light outputted from the visible light illuminator, on a basis of an image signal, a projection lens that projects light modulated by the light valve onto a projection plane, a detection light-source section (30) that outputs invisible light for detection, and an imaging device that receives a second polarized component included in light that is based on the invisible light. The detection light-source section (30) is movable relative to the housing (120), and outputs the invisible light in a direction parallel to or a direction forming a fixed angle with respect to the projection plane (110).

An example system, including a projector unit, an all-in-one computer attachable to the projector unit, a camera communicatively coupled to the all-in-one computer, and a touch sensitive mat communicatively coupled to the all-in-one computer. The projector unit projects an image on to the touch sensitive mat, and the touch sensitive mat comprises an optical pattern used to track a handheld device interacting with the image.

The disclosure relates to a method for the contactless shifting of visual information, in which at least one viewing direction, a movement of a hand and/or a movement of a head of a user are detected. After the detection of the visual information in a first display area, and after a motion indicating a shift, the visual information is shown in the second display area upon the completion of the pivoting movement or movements.

An input device includes an input surface, at least one first detector which detects a touch and/or an activation of the input surface, a second detector which includes a detection range which covers the input surface, and an evaluation unit. The second detector detects a no-touch of the input surface. The evaluation device assigns a switching or control function to the at least one of the touch and the activation of the input surface upon the detection of the at least one of the touch and the activation by the first detector. The evaluation unit excludes the assignment of the switching or control function upon detecting the no-touch by the second detector.

A non-contact elevator control system having a control panel with multiple buttons, an image processor, a first and a second camera module, wherein the first and second camera modules are arranged at two adjacent corners of the control panel, is disclosed. When an object enters a detection range, the image processor obtains a first imaging position of the object based on a first image taken by the first camera module and a second imaging position of the object based on a second image taken by the second camera module. The image processor calculates the corresponding position of the object in the control panel according to the first and the second imaging positions, and the relative position information of the first and second imaging positions with respect to the first and second camera modules. The image processor triggers a corresponding button in the control panel based on the position.
