Automobile manufacturers are constantly trying to keep up with current technology trends and respond to today's societal challenges. Cars have become more than just a means for transportation, they are now a fully embedded technological 'multifunctional living space'. The increased complexity of automotive user interfaces, driven by the need for using consumer electronic devices in cars as well as improving comfort, and the overall user/driver experience, has sparked a range of new research within this field of study. The number of infotainment functions (controlled as tertiary tasks) with which a user can interact while driving has greatly increased, making the primary task of driving even more challenging. In creating a better automotive user experience, automobile manufacturers have unintentionally increased the cognitive load of the driver when they are performing these tertiary tasks. This research study aims to reduce the cognitive load of the driver/user by suggesting novel, simple menu design interfaces, which add design improvements in two function aspects (entertainment and comfort) by implementing visual, hands-free and gestural based interfaces. This research study will add to the body of literature aimed at improving driver safety and driving experience while performing a tertiary task.

Tactile displays are an actively studied means to convey large amount of spatial information in the car. Their advantage compared to conventional car navigation systems is their ability to free the driver's visual and auditory senses. Previously the tactile displays were integrated into the seat of a car to present multiple direction information to the driver. However, in the commercial cars the seat is used to provide the vibro-tactile warning signals, so driver might not differentiate between navigation and warning information. Furthermore, the amount of information presented with tactile displays can cause significant cognitive workload, performance degradation and distraction to the driver. In this paper, we explore different methods of encoding multiple directions information with a tactile belt in the car. We compare the vibro-tactile presentation of spatial turn-by-turn information with a conventional car navigation system to measure cognitive workload, performance and distraction of the driver. We found that drivers showed better orientation performance on the tactile display than with the conventional car navigation system. At the same time there was no difference in cognitive workload, performance, and distraction. Thus, a tactile interface can be useful to present more information than simple left or right directions in high load driving conditions in which drivers are required to observe the traffic situation with their visual and auditory senses.
This paper describes the design and preliminary test of a virtual reality driving simulator capable of conveying haptic and visual messages to promote eco-sustainable driving behavior. The driving simulator was implemented through the Unity game engine; a large street environment, including high-speed and urban sections, was created to examine different driving behaviors. The hardware setup included a gaming driving seat, equipped with a steering wheel and pedals; the virtual scenarios were displayed through an Oculus Rift headset to guarantee an immersive experience. Haptic stimulation (i.e., vibrations) was delivered to the driver through the accelerator pedal, while visual stimuli (i.e., icons and colors) were shown on a virtual head-up display. The sensory feedbacks were presented both alone and in combination, providing information about excessive acceleration and speed. Four different virtual scenarios, each one including a distracting element (i.e., navigator, rain, call, and traffic), were also created. Ten participants tested the simulator. Fuel consumption was evaluated by calculating a mean power index (MPI) in reference to the sensory feedback presentation; physiological reactions and responses to a usability survey were also collected. The results revealed that the haptic and visuo-haptic feedback were responsible for an MPI reduction, respectively, for 14% and 11% compared with a condition of no feedback presentation; while visual feedback alone resulted in an MPI increase of 11%. The efficacy of haptic feedback was also accompanied by a more relaxing physiological state of the users, compared with the visual stimulation. The system's usability was adequate, although haptic stimuli were rated slightly more intrusive than the visual ones. Overall, these preliminary results highlight how promising the use of the haptic channel can be in communicating and guiding the driver toward a more eco-sustainable behavior.

The today mainly incorporated sensory modalities vision and hearing are most often highly charged due to an increasing number, as well as a rising complexity of diversified assistance systems in vehicles. These systems, originally developed for "supporting" the driver in its tasks, increasingly directs to operation errors caused by cognitive overload. The sense of touch -as additional interaction channel -should have the ability to release cognitive load from visual and auditory channels by adapting in a natural, intuitive and non-distracting manner.
