Abstract
A walking stick includes a main part that is stick-like, a sensor that detects at least one of an acceleration of the main part and an angular velocity of the main part, a light emitter that emits light on a ground, a balance evaluator that evaluates a user's walking balance stability based on at least one of the detected acceleration and the detected angular velocity, and an emitting controller that controls a light emitting direction of the light based on a result of the evaluation and an inclination angle of the main part.
