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."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Self-service crossing aid for pedestrians","description":"A tool for a crossing aid on a mobile device.
