"Design a futuristic smart cane for visually impaired users, focusing on high-tech features for safety and mobility. The cane should include sensors for traffic environment recognition like zebra crossings, tactile paving, traffic lights, stairs, and elevator signals, with real-time voice alerts. Show the cane’s ability to detect obstacles within 50 cm, emitting beeping sounds, and alerting 'person ahead' if a person is detected. LED lights flash in dim conditions for visibility, and the GPS feature allows family members to monitor location via a smartphone app. The buttons should be labeled with Braille, and it provides vibration or sound feedback for low battery warnings."
