Using Advisory 3D Sound Cues to Improve Drivers' Performance and Situation Awareness
Within vehicle Human Machine Interface design, visual displays are predominant, taking up more and more of the visual channel for each new system added to the car, e.g. navigation systems, blind spot information and forward collision warnings. Sounds however, are mainly used to alert or warn drivers together with visual information. In this study we investigated the design of auditory displays for advisory information, by designing a 3D auditory advisory traffic information system (3DAATIS) which was evaluated in a drive simulator study with 30 participants. Our findings indicate that overall, drivers' performance and situation awareness improved when using this system. But, more importantly, the results also point towards the advantages and limitations of the use of advisory 3Dsounds in cars, e.g. attention capture vs. limited auditory resolution. These findings are discussed and expressed as design implications.
Back-seat driver: Spatial sound for vehicular way-finding and situation awareness
Frontier of Computer …, 2006
We are exploring IDSS (intelligent driver support systems), especially including way-finding presented via spatial audio.(" Way-finding" refers to giving a driver directions, as via car navigation ['car-nabi"] GPS/GIS systems.) We have developed a networked driving simulator as a virtual-reality based interface (control/display system) featuring integration with the Sc haire rotary motion platform for azimuth-display, stereographic display for 3D graphics, and spatial audio (sound spatialization) way-finding cues. A design for a ...
Report on the In-vehicle Auditory Interactions Workshop: Taxonomy, Challenges, and Approaches
2015
As driving is mainly a visual task, auditory displays play a critical role for in-vehicle interactions.To improve in-vehicle auditory interactions to the advanced level, auditory display researchers and automotive user interface researchers came together to discuss this timely topic at an in-vehicle auditory interactions workshop at the International Conference on Auditory Display (ICAD).The present paper reports discussion outcomes from the workshop for more discussions at the AutoUI conference.
Automotive Audio Augmented Reality
HAL (Le Centre pour la Communication Scientifique Directe), 2020
Sound is everywhere. Manipulating complex sound material has never been so easy and achieved good quality audio has never been so accessible. In the broad variety of audio systems, automotive industry offers a very specific audio product which become the customer's choice criteria: Cars is becoming the best place to listen to music and offer outstanding / smart / emotional sound experiences through innovative technologies. In the meantime, augmented reality entertainment market is intensively growing in many fields. By combining auditory cues to reality, automotive audio augmented reality aims to extend the real world to propose a multisensorial object. By evolving toward electric, connected and autonomous vehicles, a new relationship is going to emerge between cars and their occupants. From entertainment to dynamic sound, acoustic experiences on board, experience will be immersive, proactive and contextual. This article proposes an exploration of audio augmented reality in the automotive fields from sound design to regulation with a focus on audio and NVH tools.
A dynamic binaural synthesis system for investigation into situational awareness for truck drivers
2016
Yearly, a number of accidents happen, where cyclists are injured by right turning trucks. In Denmark, the proposed solution has been to provide a higher number of mirrors to the truck driver in order to cover visual blind spots. However, this doesn't seem to eliminate the problem. Investigations into the reason for this point to cognitive phenomena such as change blindness, where more visual information won't help. For other professional vehicle operators such as pilots, auditory solutions adding to a higher situational awareness has proven valuable. This paper describes the development of a dynamic binaural synthesis system for investigation into situational awareness for truck drivers. The system is built around several software components enabling the 3D positioning of an auditory representation of a bicycle. The sound is played back over headphones to the truck driver whose head movements are monitored and taken into account in the binaural sound synthesis. To enable experiments in real traffic, the system facilitates an operator interface where the investigator can position the auditory objects according to real bicycles appearing in the traffic. The software is organized in a number of modules communicating over a network protocol (UDP) enabling distribution on several hardware devices. The modules are: Graphical user interface, head tracking server, truck tracking, and binaural synthesis module. The function of the individual modules as well as overall topology of the system will be presented, and initial practical experience with the system used in real driving situations will be discussed.
2006 IEEE/ACM International Symposium on Mixed and Augmented Reality, 2006
In cars, Augmented Reality is becoming an interesting means to enhance active safety in the driving task. Guiding a driver's attention to an imminent danger somewhere around the car is a potential application. In a research project with the automotive industry, we are exploring different approaches towards alerting drivers to such dangers. First results were presented last year. We have extended two of these approaches. One uses AR to visualize the source of danger in the driver's frame of reference while the other one presents information in a bird's eye schematic map. Our extensions were the incorporation of a real Head-up Display, improved visual perception and acoustic support. Both schemes were evaluated both with and without 3D encoded sound. This paper reports on a user test in which 24 participants provided objective and subjective measurements. The results indicate that the AR-based three-dimensional presentation scheme with and without sound support systematically outperforms the bird's eye schematic map.
Auditory interfaces in automated driving: an international survey
This study investigated peoples’ opinion on auditory interfaces in contemporary cars and their willingness to be exposed to auditory feedback in automated driving. We used an Internet-based survey to collect 1,205 responses from 91 countries. The respondents stated their attitudes towards two existing auditory driver assistance systems, a parking assistant (PA) and a forward collision warning system (FCWS), as well as towards a futuristic augmented sound system (FS) proposed for fully automated driving. The respondents were positive towards the PA and FCWS, and rated the willingness to have automated versions of these systems as 3.87 and 3.77, respectively (on a scale from 1 = disagree strongly to 5 = agree strongly). The re- spondents tolerated the FS (the mean willingness to use it was 3.00 on the same scale). The results showed that among the available response options, the female voice was the most preferred feedback type for takeover requests in highly automated driving, regardless of whether the respondents’ country was English speaking or not. The present results could be useful for designers of automated vehicles and other stakeholders.
Evaluating a vehicle auditory display
Proceedings of the 29th Annual European Conference on Cognitive Ergonomics - ECCE '11, 2011
This paper illustrates a method for the early evaluation of auditory displays in context. A designer was questioned about his expectations of an auditory display for Heavy Goods Vehicles, and the results were compared to the experiences of 10 listeners. Sound design is essentially an isolated practice and by involving listeners the process can become collaborative. A review of the level of agreement allowed the identification of attributes that might be meaningful for the design of future auditory displays. Results suggest that traditional auditory display design guidelines that focus on the acoustical properties of sound might not be suitable.
