I saw how big the font was on a friends iMessage and thought big buttons. Why?
Ease of Use: Larger buttons would be easier to press accurately, reducing the chance of hitting the wrong key. Especially important for people with larger fingers or those who may have difficulty seeing a small font.
Visibility: Big buttons are easier to see, obviously, which can help reduce typos. This is particularly beneficial for individuals with visual impairments or those who are working in low-light conditions.
Speed: With larger buttons, users can enter numbers and operations quickly without the need for careful precision. This can enhance efficiency, particularly in environments where quick calculations are frequently required.
Ergonomics: Calculators with big buttons are often more comfortable to use, reducing strain on the fingers and hands during extended use.
Accessibility: For older adults or people with disabilities, large-button calculators can be a crucial tool to maintain independence and accuracy in managing tasks that require numerical input.
Overall, calculators with big buttons can improve accuracy, speed, comfort, and accessibility, making them a better choice for many users.
