Users of traditional white canes are predominantly blind or have some sort of vision loss. Also, a large number of users have both vision loss and hearing impairment to some extent. The only information gathered by users of traditional canes is that of what they can feel through contact of the cane with their environment. However, a traditional cane does not convey to the user knowledge of which direction to move when an obstacle is in the way. A seeing-eye dog is a common but expensive solution to this problem.
The solution is developing a cane that would serve the functions of a seeing-eye dog but would not incur the costs. The Smart Cane is an innovative solution that provides haptic feedback to the user that indicates the direction in which a user should move in avoidance of impending obstacles.

The Roller Sub-Assembly was designed with the intent of providing the most effective haptic communication to the user. The design converged after acquiring data from a variety of user tests regarding the optimal ‘bump’ height and ‘bump’ rotational speed .
A series of multiple tests were conducted to ensure that each of the engineering requirements were met. The final test results confirmed that the design met the specifications.
