<span style="font-weight: 400;">he aim of our project is to create a proof-of-concept for a tool that can help blind and/or visually impaired (B/VI) individuals and orientation and mobility (O&M) instructors in their training. We are inspired by the Cane Game developed by Prof. Paul Ruvolo and the OCCaM Lab at Olin College [1].</span></b>
<br>Analyzing the frequencies of the cane sweep can help train a user to be more consistent with the sweep of their cane as they are learning to navigate.

<h3 class="u-text u-text-1">Why it matters.</h3>
<p class="u-text u-text-2"> W<b>
<span style="font-weight: 400;">e chose to focus on the importance of learning how to move the cane at a consistent rate. The speed should somewhat approximate that which will be reached during ambulation [2], and the cane user should walk out-of-step with their cane sweeping motion such that their forward foot is on the opposite side of their body as the cane tip [3]. The first step to this training is practicing sweeping the cane without moving, and the early stages of learning should be geared for accuracy and not speed [2].</span></b>

<span style="font-weight: 400;">ecause practice is important for mastery of a skill, we hope that this proof-of-concept can be used to help B/VI individuals in the early stages of learning how to use a white cane. Students can get objective, quantified feedback about the performance of their sweeps without the direct instruction of an O&M. Furthermore, O&M instructors may be able to use our tool to remotely help their students and get results without having face-to-face, active lesson time.</span></b>
