Abstract
A tool for a crossing aid on a mobile device. The tool determines a unique ID associated with a crossing signal, wherein determining the unique ID associated with the crossing signal includes scanning a machine-readable tag of the crossing signal via near field communication. The tool searches for a wireless access point (WAP) having the unique ID. The tool determines whether the WAP having the unique ID is found. Responsive to determining that the WAP having the unique ID is found, the tool determines haptic feedback.
Claims20
A method for a crossing aid on a mobile device, the method comprising:
- determining, by a first computer processor, a unique ID associated with a crossing signal, wherein determining the unique ID associated with the crossing signal includes scanning a machine-readable tag of the crossing signal via near field communication;
- searching, by the first computer processor, for a wireless access point (WAP) having the unique ID;
- determining, by the first computer processor, whether the WAP having the unique ID is found, wherein determining whether the WAP having the unique ID is found includes determining a service set identifier (SSID) of the WAP includes the unique ID extracted from a machine-readable tag of the crossing signal;
- responsive to determining that the WAP having the unique ID is found, determining, by the first computer processor, haptic feedback.
A computer program product for a crossing aid on a mobile device, the computer program product comprising:
- one or more computer readable storage media and program instructions stored on the one or more computer readable storage media, the program instructions comprising:
- program instructions to determine a unique ID associated with a crossing signal, wherein determining the unique ID associated with the crossing signal includes scanning a machine-readable tag of the crossing signal via near field communication;
- program instructions to search for a wireless access point (WAP) having the unique ID;
- program instructions to determine whether the WAP having the unique ID is found, wherein determining whether the WAP having the unique ID is found includes determining a service set identifier (SSID) of the WAP includes the unique ID extracted from a machine-readable tag of the crossing signal;
- responsive to determining that the WAP having the unique ID is found, program instructions to determine haptic feedback.
A computer system for a crossing aid on a mobile device, the computer system comprising:
- one or more computer processors;
- one or more computer readable storage media;
- and
- program instructions stored on at least one of the one or more computer readable storage media for execution by at least one of the one or more computer processors, the program instructions comprising:
- program instructions to determine a unique ID associated with a crossing signal, wherein determining the unique ID associated with the crossing signal includes scanning a machine-readable tag of the crossing signal via near field communication;
- program instructions to search for a wireless access point (WAP) having the unique ID;
- program instructions to determine whether the WAP having the unique ID is found, wherein determining whether the WAP having the unique ID is found includes determining a service set identifier (SSID) of the WAP includes the unique ID extracted from a machine-readable tag of the crossing signal;
- responsive to determining that the WAP having the unique ID is found, program instructions to determine haptic feedback.
