Although simple, the white cane continues to be the primary tool for obstacle avoidance and navigation for the blind.
We wanted to improve this often overlooked utility, by developing a product that provides enhanced feedback from the environment.
Our design utilizes sensors and light. A water sensor located in the tip of the cane identifies potentially hazardous conditions (e.g.
puddles and slippery floor surfaces). When a detection is made, the user is alerted through vibration in the handle.
LEDs are strategically located at the end of the cane to catch the attention of pedestrians distracted by cellphones. Light output increases in intensity when the cane is actively in use (tapping). This increases awareness and minimizes the potential for collision.
