Grandma's Telephone
95% of the elderly will get "Presbyopia", also known as "老花眼" in Chinese. The symptoms and drawback of this aging of the eyes include worsening ability to focus clearly on close objects. This will increase the difficulty of reading small print, having to hold reading material farther away, headaches, and eyestrain. Plus, memory loss, is also one of the symptoms of aging. In my experience, most of the elderly has a lot of free time; most of them choose to chat and chill to kill time. However, with COVID-19, they cannot meet up, nor they do not know how to use more advance technology such as facetiming, causing some to feel depression and anxiety. Combining all the reasons, I want to make a device that can show the phone number of the person the elderly wants to chat with by lighting up the LED, number by number, to tutorial them the correct phone number on a tradition telephone when they press the button. The LED's sequence helps the elderly to show/remember the phone number of the person he wants to chat with, in which solves the problem of memory loss. Second, the LED glowing at the position of the number solves the Presbyopia problem because through the position of the lighting, the elderly will be able to know where to press. Third. the device is espically for traditional telephones to suit the elderly's needs because they might not know how to use a smart phone. At last, the activation buttons are big and reachable, with clear icons showing the purpose of the call; one is for emergency usage(when the elderly is not feeling well), one if for chatting usage.
PS: My grandma will be my target audience for this product since she had been faing these difficulities, so the phone number will be a friend of hers in Pingtung, Taiwan: 0811656067
