The way drivers operate in-car systems is rapidly changing as traditional physical controls, such as buttons and dials, are being replaced by touchscreens and touch-sensing surfaces. This has the potential to increase driver distraction and error as controls may be harder to find and use. This paper presents an in-car, on the road driving study which examined three key types of input controls to investigate their effects: a physical dial, pressure-based input on a touch surface and touch input on a touchscreen. The physical dial and pressure-based input were also evaluated with and without haptic feedback. The study was conducted with users performing a list-based targeting task using the different controls while driving on public roads. Eye-gaze was recorded to measure distraction from the primary task of driving. The results showed that target accuracy was high across all input methods (greater than 94%). Pressurebased targeting was the slowest while directly tapping on the targets was the faster selection method. Pressure-based input also caused the largest number of glances towards to the touchscreen but the duration of each glance was shorter than directly touching the screen. Our study will enable designers to make more appropriate design choices for future in-car interactions.

“…Their findings indicate improved error rates and task completion times with haptic feedback enabled. The authors' own follow-up study [4] evaluated the effects of haptic feedback on the performance of an abstracted touchscreen task in an immersive simulated driving environment. Results showed reduced task completion time along with subjective preference for combined visual and haptic feedback.…”

“…Given that the purpose of the study was to evaluate the effectiveness of the feedback mechanism rather than the graphical user interface, an alternative, less demanding task may provide clearer results at the expense of physical validity. A subsequent study conducted by the authors [4] used an abstracted "search and select" touchscreen task requiring participants to locate and press a target button within a 3 × 3 array. This task featured a lower training threshold, and it was found that subjective workload, when measured using the same scales applied in this study, was lower and order effects nonsignificant.…”

“…As visual attention must be directed to the touchscreen during use, the interface imposes significant levels of visual workload upon the user; over 70% of the time taken to complete an invehicle touchscreen task can be spent looking away from the road [4]. This has implications for safety: accident risk is correlated to both the duration and frequency of glances away from the forward roadway [5], and large-scale studies have found that up to 60% of crashes, near-crashes, and incidents can be attributed to visual distraction from the primary driving task [6].…”

Touchscreen interfaces are widely used in modern technology, from mobile devices to in-car infotainment systems. However, touchscreens impose significant visual workload demands on the user which have safety implications for use in cars. Previous studies indicate that the application of haptic feedback can improve both performance of and affective response to user interfaces. This paper reports on and extends the findings of a 2009 study conducted to evaluate the effects of different combinations of touchscreen visual, audible, and haptic feedback on driving and task performance, affective response, and subjective workload; the initial findings of which were originally published in (M. J. Pitts et al., 2009). A total of 48 non-expert users completed the study. A dual-task approach was applied, using the Lane Change Test as the driving task and realistic automotive use case touchscreen tasks. Results indicated that, while feedback type had no effect on driving or task performance, preference was expressed for multimodal feedback over visual alone. Issues relating to workload and cross-modal interaction were also identified.

An in-car study was conducted to examine different input techniques for list-based scrolling tasks and the effectiveness of haptic feedback for in-car touchscreens. The use of physical switchgear on centre consoles is decreasing which allows designers to develop new ways to interact with incar applications. However, these new methods need to be evaluated to ensure they are usable. Therefore, three input techniques were tested: direct scrolling, pressure-based scrolling and scrolling using onscreen buttons on a touchscreen. The results showed that direct scrolling was less accurate than using onscreen buttons and pressure input, but took almost half the time when compared to the onscreen buttons and was almost three times quicker than pressure input. Vibrotactile feedback did not improve input performance but was preferred by the users. Understanding the speed vs. accuracy trade-off between these input techniques will allow better decisions when designing safer incar interfaces for scrolling applications.
