Hand-Held texting is less distracting than texting with the phone in a holder: anyway, don't do it

2015

We studied the effects of texting while driving and the effects of mobile phone position (hand-held, holder) on drivers' lane-keeping performance, experienced workload, and in-car glance durations in a motion-platform driving simulator with 24 participants. Overall, we found the known negative effects of texting on lane-keeping performance, workload, and visual attention on road, suggesting that texting on the road in any manner is not risk-free. As a novel finding, we found that hand-held texting led to fewer lane-keeping errors and shorter total glance times off road compared to texting with the phone in a holder. We suggest the explanation is that the drivers had considerably more experi…

Browsing the information highway while driving: three in-vehicle touch screen scrolling methods and driver distraction

2012

Distraction effects of three alternative touch screen scrolling methods for searching music tracks on a mobile device were studied in a driving simulation experiment with 24 participants. Page-bypage scrolling methods with Buttons or Swipe that better facilitate resumption of visual search following interruptions were expected to lead to more consistent in-vehicle glance durations and thus, on less severe distraction effects than Kinetic scrolling. As predicted, Kinetic scrolling induced decreased visual sampling efficiency and increased visual load compared to Swipe, increased experienced workload compared to both Buttons and Swipe, as well as decreased lane keeping accuracy compared to ba…

Käyttöliittymäkehitys kosketuskäyttöisille älypuhelimille

2012

Kosketusohjauksen ja sovelluskauppojen läpimurron seurauksena älypuhelinvalmistajat ovat viime vuosina panostaneet entistä enemmän laitealustojensa käytettävyyteen sekä kolmansille osapuolille tarkoitettuihin kehitystyökaluihin. Samaan aikaan markkinoille on ilmestynyt lukuisia ratkaisuja sovellusten alustariippumattomaan toteutukseen. Tässä työssä tutustutaan sovelluskehittäjille tarjottuihin vaihtoehtoihin käyttöliittymäkehityksen perspektiivistä ja selvitetään ovatko yleistyvät web-pohjaiset alustariippumattomat ratkaisut varteenotettava vaihtoehto natiiveille kehitystyökaluille. Following the rise of app stores and touch user interface driven smartphones in the recent years, practically…

Critical Analysis on the NHTSA Acceptance Criteria for In-Vehicle Electronic Devices

2014

We tested a commercial in-car navigation system prototype against the NHTSA criteria for acceptance testing of in-vehicle electronic devices, in order to see what types of in-car tasks fail the acceptance test and why. In addition, we studied the visual demands of the driving scenario recommended by NHTSA for task acceptance testing. In the light of the results, NHTSA guidelines and acceptance criteria need to be further developed. In particular visual demands of the driving scenario and for different simulators need to be standardized in order to enable fair testing and comparable test results. We suggest the visual occlusion method for finding a driving scenario that corresponds better wi…

Impacts of Touch Screen Size, User Interface Design, and Subtask Boundaries on In-Car Task's Visual Demand and Driver Distraction

2020

Visual distraction by secondary in-car tasks is a major contributing factor in traffic incidents. In-car user interface design may mitigate these negative effects but to accomplish this, design factors’ visual distraction potential should be better understood. The effects of touch screen size, user interface design, and subtask boundaries on in-car task's visual demand and visual distraction potential were studied in two driving simulator experiments with 48 participants. Multilevel modeling was utilized to control the visual demands of driving and individual differences on in-car glance durations. The 2.5” larger touch screen slightly decreased the in-car glance durations and had a diminis…
