Abstract

Disclosed is a process through which the applications in liquid crystal display devices at point of sale stations in a retail environment can automatically determine whether to operate in a manned or self-checkout mode. The solution utilizes a built-in magnetic field sensor which provides updates to the system software when the relative position of the screen changes compared to magnetic North. The position of the screen indicates whether it is facing the point of sale operator or the customer, and the application initiates the appropriate operating mode.

Using Earth's magnetic field to control application in transaction based terminals

Many retail outlets now have liquid crystal display (LCD) monitors as point of sale (POS) devices. Many retailers offer self service lanes for customer use; lanes without customer service associates are self checkout lanes. The application software required is completely different for manned vs. self checkout lanes. Software to automatically determine in which mode, manned [Figure 1] vs. self checkout [Figure 2] it should run serves to increase efficiency at the POS station [Figure 3]. This disclosure describes a process for directing the application in which mode to run.

The display contains a built-in magnetic field sensor [Figures 4a and 4b], similar to the magnetic field sensor built into automobile mirrors that indicate direction to the driver. This sensor provides updates to the system software when the relative position of the screen changes compared to magnetic North [Figure 5]. The software then determines whether the display is facing the operator or the customer and run the appropriate application.

The solution provides a high level of granularity on display position. This allows the operator, customer, or installer to determine screen position as well as areas of screen position for manned vs. unmanned operation. In addition, it does not require the installation of positioning hardware (magnets, optical marks, etc.) in the mount for the display; everything needed for position detection is inc...
