Conventional canes for the visually impaired cannot help their users identify the scale of unknown objects in the walker’s path, thus presenting a potential danger to the walker. By changing the shape of the cane, Triangle Freedom uses simple geometric lines to probe small spaces and improve the safety of visually impaired walkers while providing an intuitive way for determining the location of obstacles.

Through observation and experimentation, conventional canes are found to have the following problems:
1. Cane movement in the path creates a triangular blind spot
2. The position of the cane tip is different than that of the foot
