CoughDrop tries to accommodate different motor capabilities with various button sensitivity options. You can trigger button selection immediately, only after a minimum amount of time, or after a delay even without releasing the touch or click. For individuals with fine motor control concerns you can specify whether to select the button where the user started selection, or where they ended up. Button sensitivity and response settings are configured as a per-device setting.
Access to the Preferences page by hitting the profile icon in the top right corner and selecting "Preferences".
