Small UI elements such as buttons and links are difficult to operate, but the inability to quantitatively study operability has been a problem for designers. Using our tool suite “Tappy,” we can estimate tap success rates with high accuracy based on the size of UI elements, and identify areas where links are too small or buttons are unnecessarily taking up too much screen space. This talk includes the following contents.
- How to use Tappy
- Examples of Tappy applications
- Theoretical background of the tap success rate calculation method.
