ABSTRACT
Social aging is an important global issue, and care for the elderly has become the focus of attention from all walks of life. With the increase of age, the articular cartilage has obvious changes in structure, molecules, cells and mechanical mechanics, which increases the vulnerability of tissue degradation. In addition to the inconvenience of walking in life, the elderly have difficulty in sitting up which is a big problem. At present, there are not many mobile assistive devices with stand-up assistance on the market, and the evolution has been slow. This study asked 10 users with an average age of 90 years old, including 2 males and 8 females, to ask questions about the use of assistive devices through questionnaires to understand the needs of users. The question is mainly divided into 3 types of assistive devices, measured by 5 points Likert, to understand the user's opinions on technology acceptance (easy to use, useful, attitude, willingness to act), the results show that design A To reduce the burden, weight affects the use of these two needs to be improved. Design B is inferior in the simplicity of folding, but better in portability. Design C's attributes of assisting action, increasing willingness to use the product, feeling easy to use, being worth using, helping to do things, etc., all need to be improved. In the future, we will provide better design solutions for the elderly through participatory design methods at several meetings. Then, arrange comparative experiments to test the practicability of the new design.
