Abstract
Improvements in a line tracking cane for the vision impaired. The cane detects a line and notifies the user with a sound or vibration to indicate that is user is aligned with the line as the user passes the cane back-and-forth over the line. The detector can detect a direction of movement over the line to determine if the tip of the cane has completely passed over the line or has just moved half-way over the line. The cane is rechargeable and has a handle that orients the sensor on the tip of the cane to forward. The handle has an on-off or momentary power button. The cane can be collapsible as a folding cane or a telescoping cane. It is also contemplated that the tracking device can be an adapter for an existing cane to upgrade the functions of pre-existing cane.
Claims19
A line tracking cane for the vision impaired comprising:
- a cane having an optical sensor at a first end of said cane;
- said cane further having a power switch that is configured to power said optical sensor to detect a reflective surface;
- a vibration device connected between said optical sensor and said power whereby when said optical sensor detects said reflective surface, said vibration device is activated to produce a vibration to said cane and,
- a detection head that is wired to a separate control housing wherein said detection head is configured to be retained on a fixed portion of a rotatable tip.
