37 results about "Operational display system" patented technology

Operational Display Systems refers to systems used for tracking the status of multiple objects in avionics. Operational Displays Systems are usually being developed by large countries' civil aviation authorities (such as the Federal Aviation Administration in the United States, or the main Service Providers in Europe, such as DFS, NATS, DSNA, AENA, MUAC, etc., coordinated by Eurocontrol in Europe), with inputs from technology companies and air traffic controllers associations.

The invention discloses an operation method for electronic information equipment. The operation method comprises the following steps of: determining the coordinates of an operation point in a display interface of a system; acquiring the limb movement information of an operator to obtain the space coordinate information and image data of a limb, and outputting the obtained image data in a mirror form by using a display screen; calculating the coordinates of a mirror point of the limb in the display screen; and identifying limb movement, judging whether the mirror point of the limb corresponds to the operation point or not, performing operation in response to the limb movement by using the system if the mirror point of the body corresponds to the operation point, otherwise not responding to the limb movement. In addition, the invention also provides a corresponding stereoscopic-vision-based operation display system. The coordinates of an image on the display screen correspond to the space coordinates of the limb of the operator on the basis of a mirror display technology and a machine vision technology, and a user can see own operating position relative to the screen on the display screen under a second-dimensional (2D)/three-dimensional (3D) display condition, so that the electronic information equipment can be accurately operated at a distance.
