Abstract

A walker is a device that is prescribed to help a certain user such as a lower limb disabled, elderly, or blind person move. Nowadays, technological advancements have the potential to improve the quality of life of the lower limb disabled or elderly by developing various types and functions of walkers to assist with their daily life activities; however, these walkers have limitations that may be harmful to the user's body. The aim of the research work described in this report is to design and phototype development of walker for IoT device monitoring analysis using Blynk application. Additionally, evaluating the performance of the variable device monitor, which is heart rate, step count and fall detection monitor. The QFD is a technique for gathering consumer feedback and converting the needs of the responders into technical specifications. In accordance with the information gathered from the interview session, the House of Quality (HOQ) of walker was constructed, which was then used to examine the product's features and its connection matrix. Besides, the standard walker will cause users to present a forward-leaning posture which will cause them to suffer from back or neck pain. The user's requirements were satisfied and the issues they ran into while using the walker were resolved via modification and enhancement of the device. In addition, the QFD integrated model is developed and validated via analysis of the design process and results. Simultaneously the next step is engineering drawing and 3D modelling. By utilising the QFD integration, the walker might be improved with a workable solution. By using the integration on QFD could help in improving the walker with a suitable solution. After do the 3D modelling, the process of prototype the walker has conducted. And the lastly is doing the testing on the walker. Usability test is the method that used in the testing product.
