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…
Measuring Distraction at the Levels of Tactical and Strategic Control: The Limits of Capacity-Based Measures for Revealing Unsafe Visual Sampling Mod…
2011
The control theory of driving suggests that driver distraction can be analyzed as a breakdown of control at three levels. Common approach for analyzing distraction experimentally is to utilize capacity-based measures to assess distraction at the level of operational control. Three driving simulation experiments with 61 participants were organized to evaluate which kind of measures could be used to analyze drivers' tactical visual sampling models and the related effects of distraction while searching textual information on in-car display. The effects of two different text types were evaluated. The utilized capacity-based measures seemed to be insufficient for revealing participants' tactical…
Visual Distraction Effects between In-Vehicle Tasks with a Smartphone and a Motorcycle Helmet-Mounted Head-Up Display
2018
Besides motorists, also motorcyclists need safer user interfaces to interact with useful applications on the road. In this paper, distraction effects of in-vehicle tasks conducted with a head-up display (HUD) for motorcyclists were compared to smartphone tasks with 24 participants in a driving simulator. Compared to the smartphone tasks, the head-up display tasks decreased the percentage of inappropriately long glances by 45 percent. The head-up display tasks were also experienced as less demanding than the smartphone tasks. Additionally, the use of head-up display for navigation did not lead to gaze concentration effects compared to baseline driving. The head-up display is concluded to be …
Driver Distraction Detection Using Bidirectional Long Short-Term Network Based on Multiscale Entropy of EEG
2022
Driver distraction diverting drivers' attention to unrelated tasks and decreasing the ability to control vehicles, has aroused widespread concern about driving safety. Previous studies have found that driving performance decreases after distraction and have used vehicle behavioral features to detect distraction. But how brain activity changes while distraction remains unknown. Electroencephalography (EEG), a reliable indicator of brain activities has been widely employed in many fields. However, challenges still exist in mining the distraction information of EEG in realistic driving scenarios with uncertain information. In this paper, we propose a novel framework based on Multi-scale entrop…
Formatiivinen arviointi ja siihen vaikuttavat häiriötekijät yläkoulun biologian opetuksessa
2018
Uuden suomalaisen perusopetuksen opetussuunnitelman myötä vuorovaikutuksen merkitys korostuu yhä enemmän opetuksessa. Oppilaita aktivoivat tutkivan oppimisen työtavat ovat yleistyneet tavanomaisen opettajajohtoisen opetuksen rinnalla ja lisäksi painotetaan opetusmenetelmien monipuolisuutta sekä opetuksen eriyttämisen tärkeyttä. Viimeisimpien tutkimustuloksien tukemana formatiivisen arvioinnin nähdään vaikuttavan sekä opettamiseen että oppilaiden oppimiseen positiivisesti. Formatiivinen eli jatkuva arviointi mahdollistaa opetuksen kohdentamisen ja muokkaamisen jo oppimisprosessin aikana. Tutkimuksen tavoitteena oli selvittää keskustelusyklien esiintymistä ja laatua opettajajohtoisessa sekä t…
