  1. large touch screens usable while driving Sonja Rümelin | Andreas Butz

  2. Motivation Related work Concepts Study Results

  3. Recent development: LARGE touch screens • Tesla Model S 2012

  4. Concepts: Large Interactive cockpits • Toyota Fun Vii 2012 • Daimler DICE 2012 • Opel Monza Concept 2013

  5. Why touch? Harvey et al. (2011), Ergonomics: Touch screens (compared to rotary controllers) provide advantages regarding • visual distraction (less) • interaction time (less) • driving performance (better) • usability (better)

  6. Why NOT touch? No haptic feedback like buttons • Visual attention required! • Decreased interruptability! Noy et al. (2004) • Increased crash risk! Klauer et al. (2006)

  7. So How touch? Bach et al. (2008), CHI : Ecker et al. (2009), AutoUI: Touch (gestures) can enable blind interaction at the expense of interruptability Touch buttons= fast Touch gestures = reduced visual attention

  8. So How touch? El-Glaly et al. (2013), TEI: Haptic elements to enhance touch screens for eyes-free use Pielot et al. (2012), MobileHCI: Make use of existing hardware elements to ease orientation

  9. concept Precondition: Use a large touch screen in the center stack (17´´) Approaches: Make things as large as possible (Fitt‘s law!) Make use of available haptic elements Make use of position-independent controls Goal: Show that large screens can be used while driving!

  10. USE CASE • Music player control • commonly performed task • like Bach et al. (2008), Döring et al. (2011) • Functionality • play/pause • skip song forward/backward • skip playlist forward/backward ID4 SmallTouch

  11. realization • Make things as large as possible (Fitt‘s law!) • Make use of available haptic elements • Make use of position-independent controls SpaceTouch KnobTouch SwipeTouch

  12. Study design • 40 participants, within-subjects design, 90 minutes • comparison to two standard interfaces • driving in fixed-based simulation (car following task) > 3500 tasks performed overall BMW iDrive SmallTouch

  13. results Task completion time: best for SpaceTouch Error rate: overall low, confusion of gesture directions Learnability: SpaceTouch and KnobTouch easiest to learn Complexity: rated low for SpaceTouch and SmallTouch Confidence: best with remote control of iDrive system SpaceTouch KnobTouch BMW iDrive SmallTouch SwipeTouch ? !!!

  14. results Visual distraction: least for SwipeTouch, followed by remote control User experience: High hedonic quality for SwipeTouch and KnobTouch No negative effect of any touch interface on driving performance compared to remote control SpaceTouch KnobTouch BMW iDrive SmallTouch SwipeTouch UX

  15. Direct touch: easy to learn & quick to use & the larger the better (Our) large was not large enough Haptics (knob, border) did help Swipe works without having to look, but design is critical
