The elderly and disabilities usually can't move fast on street. It is Dangerous if they are making a turn while a car or rider coming behind them. Based on the problem, we design a cane with direction light.While making a turn, the user can simply press the directional buttons in the concave to project the turn signal, which can help others around aware that the user is about to make a turn. If users decide to turn right and press the corresponding buttons, the projection will be casted on the right front of the cane, and vice versa.
