Elevator system and operating terminal having graphical user interface

An elevator system, comprising:

• an elevator car configured to move between floors of a building;
• an elevator controller configured to control the elevator car to move between the floors of the building;
• and
• an operating terminal communicatively coupled to the elevator controller,
• wherein the operating terminal comprises a three-dimensional sensor system and a touch-sensitive screen system configured to generate a graphical user interface for display on a touch-sensitive screen of the touch-sensitive screen system, the graphical user interface comprising predetermined content,
• wherein the three-dimensional sensor system is configured to determine a surface area on the touch-sensitive screen to be touched by a user when selecting displayed content of interest, and to generate a control signal comprising at least one indication specifying the surface area when an object moved by the user is within a predetermined distance from the touch-sensitive screen;
• and
• wherein the touch-sensitive screen system is configured to generate a display region within the graphical user interface in response to the at least one indication, wherein the display region includes an enlargement of content related to the surface area and the displayed content of interest, and wherein the display region is sized to overlap at least a portion of the surface area.

An operating terminal, comprising:

• a communication terminal which is configured to communicate with an elevator controller of an elevator system;
• a central control and processing terminal which is communicatively connected to the communication terminal;
• a three-dimensional sensor system;
• and
• a touch-sensitive screen system configured to generate a graphical user interface for display on a touch-sensitive screen of the touch-sensitive screen system, the graphical user interface comprising predetermined content,
• wherein the three-dimensional sensor system is configured to determine a surface area on the touch-sensitive screen to be touched by a user when selecting displayed content of interest, and to generate a control signal comprising at least one indication specifying the surface area when an object moved by the user is within a predetermined distance from the touch-sensitive screen;
• and
• wherein the touch-sensitive screen system is configured to generate a display region within the graphical user interface in response to the at least one indication, wherein the display region includes an enlargement of content related to the surface area and the displayed content of interest, and wherein the display region is sized to overlap at least a portion of the surface area.

A method for operating an elevator system comprising an elevator car, an elevator controller and elevator operating terminals which are communicatively connected to the elevator controller and are configured for inputting an elevator call, wherein an elevator operating terminal comprises a three-dimensional sensor system and a touch-sensitive screen system comprising a touch-sensitive screen, wherein the method comprises:

• generating, by the touch-sensitive screen system, a graphical user interface for display on the touch-sensitive screen of the touch-sensitive screen system, the graphical user interface comprising predetermined content;
• determining, by the three-dimensional sensor system, a surface area on the touch-sensitive screen to be touched by a user when selecting displayed content of interest;
• generating, by the three-dimensional sensor system, a control signal comprising at least one indication specifying the surface area when an object moved by the user is within a predetermined distance from the touch-sensitive screen;
• and
• generating, by the touch-sensitive screen system, a display region within the graphical user interface in response to the at least one indication, wherein the display region comprises an enlargement of content related to the surface area and the content of interest, and wherein the display region is sized to overlap at least a portion of the surface area.
