’Sound icons’ to warn drivers of hazards

24.03.2004


Researchers have subjected volunteers to the sounds of cockerels, bells, babies crying and footsteps to find out how people perceive urgency and pleasantness.



The two-year EPSRC-funded project aims to find the most appropriate sounds – such as those of screeching tyres or car horns – to warn drivers of hazards on the road.

Researchers from the school of psychology are helping car manufacturers come up with the best ‘audible icons’ to convey alerts to drivers by discovering the appropriateness of different sounds.


In their tests the most unpleasant sound was found to be a horn blast and the least unpleasant the sea. The most urgent was an electronic warning pulse and least urgent the sound of a house martin singing. Highly urgent sounds were also judged least pleasant.

Car manufacturers are interested in the use of ‘realistic’ sounds as alerts because they cut reaction times and increase drivers’ awareness of what is going on around them.

Sounds do not interfere with the visual aspects of driving the car and reaction time is cut if meaningful sounds are made to indicate a specific hazard rather than simply indicating that something is amiss.

Over the next year Leeds researchers aim to find out exactly which types of sounds are most suitable as audible icons in cars using the University’s advanced driving simulator. The research is necessary to ensure that a sound is perceived as having a meaning but is not so annoying that car users disable it.

Dr Denis McKeown, who is leading the project, said the use of audible icons would be particularly useful for collision detection systems being developed by car makers. These use sensors to measure the speed and distance of a vehicle from the car in front and regulate braking so the two do not collide.

He said: “Audible icons may produce significantly faster response times than tone or speech warnings but we have to find out which ones convey the right degree of urgency and a commonly-understood meaning. While using such ‘realistic’ sounds as alarms conveys more meaning there is a possibility people can respond incorrectly and not take enough time to assess the road situation themselves.”

Im Focus: The geometry of an electron determined for the first time

Physicists at the University of Basel are able to show for the first time how a single electron looks in an artificial atom. A newly developed method enables them to show the probability of an electron being present in a space. This allows improved control of electron spins, which could serve as the smallest information unit in a future quantum computer. The experiments were published in Physical Review Letters and the related theory in Physical Review B.

The spin of an electron is a promising candidate for use as the smallest information unit (qubit) of a quantum computer. Controlling and switching this spin or...

UTokyo engineers develop a way to create high-capacity long-life batteries

Engineers at the University of Tokyo continually pioneer new ways to improve battery technology. Professor Atsuo Yamada and his team recently developed a...

Im Focus: Quantum Cloud Computing with Self-Check

With a quantum coprocessor in the cloud, physicists from Innsbruck, Austria, open the door to the simulation of previously unsolvable problems in chemistry, materials research or high-energy physics. The research groups led by Rainer Blatt and Peter Zoller report in the journal Nature how they simulated particle physics phenomena on 20 quantum bits and how the quantum simulator self-verified the result for the first time.

Many scientists are currently working on investigating how quantum advantage can be exploited on hardware already available today. Three years ago, physicists...

Im Focus: Accelerating quantum technologies with materials processing at the atomic scale

'Quantum technologies' utilise the unique phenomena of quantum superposition and entanglement to encode and process information, with potentially profound benefits to a wide range of information technologies from communications to sensing and computing.

However a major challenge in developing these technologies is that the quantum phenomena are very fragile, and only a handful of physical systems have been...

Im Focus: A step towards probabilistic computing

Working group led by physicist Professor Ulrich Nowak at the University of Konstanz, in collaboration with a team of physicists from Johannes Gutenberg University Mainz, demonstrates how skyrmions can be used for the computer concepts of the future

When it comes to performing a calculation destined to arrive at an exact result, humans are hopelessly inferior to the computer. In other areas, humans are...
