Graphical configuration of signal strength range

A method of controlling user access to a first device, comprising:

• displaying on a screen a distance range icon, the distance range icon having a width in a direction extending away from a position on the screen representing the first device, the width indicative of a range of distance from the first device;
• displaying a device icon on a screen relative to the distance range icon based on a correlation between a strength of a signal being received at the first device from a second device and a distance of the second device from the first device;
• displaying on the screen, a distance range icon control for receiving user input;
• receiving a first user input, via the distance range icon control, indicative of a desired range of signal strength of a signal received at the first device from another device for which to allow the other device to log-in to the first device or an application on the first device;
• defining a signal strength range based on the first user input and adjusting the width of the distance range icon based on the signal strength range;
• detecting, at the first device, a first signal from a third device;
• determining whether a first signal strength of the first signal is within the defined signal strength range;
• and
• based at least in part on the determination of whether the first signal strength is within the defined signal strength range, determining whether to log-in a user of the third device to at least one of the first device and an application on the first device.

A system for managing access control to a first device, comprising:

• a display screen;
• and
• at least one processor coupled to a memory, the memory storing processor executable instructions that configure the at least one processor to:
• display on the display screen a distance range icon, the distance range icon having a width in a direction extending away from a position on the display screen representing the first device, the width indicative of a range of distance from the first device, the range corresponding to a signal strength range that is indicative of a range of signal strength of a signal received at the first device from another device for which to allow the another device to log-in to the first device or an application on the first device;
• for each of one or more second devices, display a device icon on the display screen at a position relative to the distance range icon indicative of an estimated current distance of the second device from the first device;
• display on the display screen, a distance range icon control configured for receiving user input indicative of a change to the range of distance;
• receive a first user input, via the distance range icon control, indicative of a change to the range of distance corresponding to a change in the signal strength range;
• and
• adjust the width of the distance range icon based on the first user input, wherein access of devices to the first device is controlled based on the signal strength range.
