Varmaan noita on aika paljon UI elementeistä ja käytettävyydestä.
Mutta tuossa nyt vaikka yksi esimerkki kosketusnäytön käyträminen vs. fyysiset näppäimet:
This paper investigates the usability of touch screens used in mass production road vehicles. Our goal is to provide a detailed comparison of conventional physical buttons and capacitive touch screens taking the human factor into account. The pilot test focuses on a specific Non-driving Related...

"The results of the comparative study are summarized as follows:
Visual distraction times and eyes-off-road distances clearly demonstrate the difference between the two types of interface design and high traffic safety risk of using IVIS in moving vehicle.
In all three driving speeds (50, 80, 130 km/h), the touch screen-based interface caused higher visual distraction (4.68–22.12%), resulting in a maximum of 20.34 m eyes-off-road distance difference.
Manual distraction times and single-hand drive distances showed a small degree of difference, but in some cases physical buttons could be used without visual attention. This is safer when performing a NDRT.
Clear differences between the examined different UI designs showed a higher distraction level when using the touchscreen.
Pupil diameter and saccades presented comparable values for showing higher cognitive load in controlled test circumstances and in the comparative study.
NASA-TLX and SUS tests coincided with the results measured by the eye-tracking system.
These results can explain the advantage of physical buttons and turning knobs. Physical buttons can be operated by the driver’s arm, hand, and fingers using “muscle memory” and complex haptic and tactile feedback without the need to focus the gaze."
Mitä keskinäyttö vs. edessä oleva näyttö, niin pään kääntö on eri kuin silmien kääntö. Myöskin väittäisin, että tilastollinen ero on varmasti löydettävissä edessä olevan näytön eduksi vaikka "molemmissa katse käännetään".
