Driving Faster or Slower? Speed Changes and Judged Effects on Fuel Consumption

Greenhouse gas emissions from the transport sector continue to increase. Lower speeds on roads would reduce fuel consumption and thereby emissions. Drivers choose the speed of their vehicles, but do they realize the full benefit of a reduced speed on fuel

Recent developments in the car industry have put Human Machine Interfaces under the spotlight. Developing gratifying human-car interactions has become one of the more prominent areas that car manufacturers want to invest in. However, concepts like

Correlation between safety assessments in the driver-car interaction design process

With the functional revolution in modern cars, evaluation methods to be used in all phases of driverecar interaction design have gained importance. It is crucial for car manufacturers to discover and solve safety issues early in the interaction design

Using naturalistic driving films as a design tool for investigating driver requirements in HMI design for ADAS

In recent years, there are many naturalistic driving projects have been conducted, such as the 100-Car Project (Naturalistic Driving study in United State), EuroFOT(European Large-Scale Field Operational Tests on Vehicle Systems), SeMiFOT(Sweden Michigan

Desirability in the development of In-Car Infotainment Systems

This paper describes a workflow for designing experiences whileinteracting with an advanced driver assistant system. Future driver assistancesystems that utilize sensors and Car2X-communication in order to detect threatsin the car environment can help the

Driving performance during visual and haptic menu selection with in-vehicle rotary device

An in-vehicle haptic rotary device developed to interact with secondary tasks can provide haptic support to a visual interface and reduce the need to look away from the road. However, added haptic information intended to support interaction may distract

Exploring the concept of Gist as a mean to find the Current Product Sign

In today’s competitive market it is essential for companies to have a clear brand identity towards it consumers and users in order to be successful. An important factor is recognition of a product and how it is conceived through our perception, which is

Effects on localization performance from moving the sources in binaural reproductions

A well-known problem for reproductions of binaural recordings and simulations using HRTFs other than those of the actual listener is decreased localization performance and increased front-back confusion. Previous studies have indicated that moving the

Judgments of mean speed and predictions of route choice

How are driving speeds integrated when speeds vary along a route? In a first study, we examined heuristic processes used in judgments of mean speed when the mean speeds on parts of the trip varied. The judgments deviated systematically from objective mean

Escaping the obvious: Skewing properties of interaction

Most design methods used within interaction design originate from other disciplines. As a result, there are few methods which can focus on designing or redesigning interaction in itself. In this paper we present a structured ideation method called Skewing

Countermeasure Drowsiness by Design - Using Common Behaviour

This study takes a starting point in what drivers do to avoid drowsiness while driving instead of starting with what researchers know is efficient (Take a short nap). It is concluded that research is missing when it comes to how efficient common behavior

Evolving the Modular Layered Architecture in Digital Innovation: The Case of the Car's Instrument Cluster

Digital innovation entails the combining of digital and physical components to produce novel products.  The materiality of digital artifacts, particularly the separation between their material and immaterial  features, which is expressed through a layered

Designing multimodal stimuli for in-vehicle information systems

The amount of complex information while driving is constantly increasing, leading to driver inattention and traffic accidents. Since the majority of this information is visual, the driver´s visual attentnion is deflected away from driving the vehicle. The
