Advanced driver assistance systems (ADAS) and driver information systems (DIS) do not always comply with the intended driver safety enhancement. Even if they aim to augment the driver's awareness of the surrounding environment, perceiving this information requires the occasional attention diversion from the road, which could lead to a loss of vehicle control if the total eyes-off-road time exceeds the National Highway Traffic Safety Administration (NHTSA) recommendation for glances away from the roadway. Additionally, technologies that can be found in other mobile environments, smartphones, and tablets are increasingly being integrated into cars, providing a necessary facet of study and continued research in their effects. We addressed this question by analyzing differential preferences for the layout of DIS and ADAS compared with existing ones through a card-sorting experiment. To validate our data, we additionally studied the drivers' performance and gaze with the preferred locations for in-vehicle information through gaze location and speed metrics measurements.Our validation process showed that the time the drivers needed to find the conveyed information in the preferred layout was within the recommended time of the NHTSA Guidelines. Drivers' preferences with regard to the functional layout of current DIS and ADAS compared with existing ones did not essentially differ from the layouts that are currently on the market. However, including mobile applications and social media in a vehicular context was not considered necessary.Index Terms-Information visualization, in-vehicle displays, vehicular user interfaces.
In User Centered Design (UCD) approaches within software development processes, understanding of users, tasks and environments identifying needs and establishing requirements for a positive user experience (UX) is essential to achieve a high usability. The quantitative measurement of UX relies on the fulfillment of psychological needs that can be addressed in storyboards in order to create a context for a certain experience with a particular application. To facilitate the process of capturing software products functionality, we present in this work a framework based on Intelligent Agent (IA) systems to semi-automatically generate user stories. A strong story line is guaranteed by a character-centric approach and additional supportive agents that are defined through characters' properties in form of needs, behaviors skills and goals. Moreover, we allow for the storage of the created characters into a database, so that they can be reused for further stories and we perform a usability evaluation on the user interface to ensure that it meets users' expectations. The system was classified as easy to use and suitable to perform the intended tasks and it also met users' expectation.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
