Smart Walkers are robotic devices used to improve physical stability and sensorial support for visually impaired people with lower limb weakness or poor balance. Such devices offer support for people with cognitive disabilities and who cannot safely use conventional walkers. This work proposes an admittance controller to guide visually impaired people. Physical interaction between user and Smart Walker is used to haptically indicate the path to be followed. The user experience is evaluated through variation of control parameters and the predetermined path, which are used to improve the Human-Robot-Environment interaction.
