Visual bio-feedback is a novel way to provide useful and real-time information to lower-limb (leg) amputees, regarding the gait speed, deviations, and impact forces of their prosthesis. The proposed visual feedback device described in this application, will allow amputees to monitor their gait in real-time, and respond accordingly. This should allow amputees to make corrective adjustments to their gait, ultimately leading to a healthier condition (less injuries, pain, or fatigue) through better gait performance. In addition, the proposed device could be used for training and rehabilitation for recent amputees. Alleles Design Studio is interested in expanding the services offered to their amputee clients. They have noticed a huge gap between current gait data collection and analysis by experts, vs. devices that could allow amputees to self-assess their gait. Although several technologies exist that gather gait information, this information is typically never seen by the end-user, and if it is, the information is not in a digestible form. The UVic team will work with Alleles to explore/develop a new device that gathers gait information, that is then immediately visually translated and interpreted by the user. This would be beneficial for recent amputees going through rehab to understand their gait, to have metrics to discuss with specialists, and to let them make immediate corrections to prevent bad habits from forming. Recent developments in microcontroller technology (low cost, low power, high computation, and small size), low cost inertial sensors, and modern manufacturing techniques, allow for the design of such a small, portable bio-feedback system.

视觉生物反馈是一种向下肢(腿)截肢者提供有用和实时信息的新方式， 关于他们假肢的步态速度、偏差和冲击力。建议的视觉反馈 本申请中描述的设备，将允许截肢者实时监测他们的步态，并做出反应 相应地。这应该允许截肢者对他们的步态进行矫正调整，最终导致 更健康的状态(更少的伤害、疼痛或疲劳)，通过更好的步态表现。此外，建议的 该装置可用于近期截肢者的训练和康复。设计工作室感兴趣的等位基因 扩大向截肢者客户提供的服务。他们注意到当前步态数据之间存在巨大差距 由专家收集和分析，而不是可以让截肢者自我评估步态的设备。虽然 存在几种收集步态信息的技术，该信息通常永远不会被终端用户看到， 如果是这样，信息就不是可消化的形式。UVic团队将利用等位基因 探索/开发一种新的设备，收集步态信息，然后立即进行可视翻译和 由用户解释。这将有助于最近接受康复的截肢者了解他们的 步态，有指标与专家讨论，并让他们立即纠正，以防止不良 养成习惯。微控制器技术的最新发展(低成本、低功耗、高性能 计算量大、体积小)、低成本的惯性传感器和现代制造技术 设计了这样一个小型、便携式的生物反馈系统。
