I have a GPS device with a solely touch interface. From the beginning, I noticed I was having a hard time using it and I eventually realized why.
Whenever the UI asks me to write something (like a town or street name), it offers a keyboard. In this context, there are two behaviors which, when combined, happen to confuse me:
- Very often, the key I tapped is not recognized (although I haven't figured out why) and I have to press it again for it to be registered.
- The device makes a beeping sound every time anything on the screen is pressed, even it doesn't correspond to a valid action.
These, when combined, create a situation where the device beeps exactly the same way every time it's touched, regardless of whether it considered the keystroke valid or not. This makes typing extremely hard for me (even though I'm very efficient at typing on a computer keyboard), which got me thinking.
Is this a known UX design pattern that I haven't heard of (and if yes, what's its name and its advantages)? Or is it simply very poor UX design?
