Cars Must Be Considerate of the Driver When Talking

26.10.2015

Smart telephones and TVs are well-established technical gadgets in today’s society. The same cannot be said about smart cars with dialogue systems that can understand you and communicate as if they were a person sitting in the seat next to you. A PhD thesis in linguistics from the University of Gothenburg presents the theory that cars should consider both the driver and the traffic situation when communicating.

By putting real persons in regular cars and letting them drive around in Gothenburg while talking to each other, Jessica Villing has explored how the interaction between the driver and modern in-vehicle dialogue systems, such as navigation systems, can be improved in order to reduce the driver’s cognitive workload and therefore increase traffic safety.

Most experiments of this type are conducted in simulators, where drivers are given mathematical problems to solve while driving. But since this is not how it happens in real life, Villing wanted to know how a real conversation with a passenger affects us when driving a car.

‘Humans are good at reading people they’re talking to, so looking at how passengers and drivers interact provides a perfect model for tomorrow’s dialogue systems,’ she says.

The Dico project (dico is Latin for ‘I speak’) is a collaboration between the University of Gothenburg, Volvo, Telia Sonera and Veridict. In her research, Villing has looked specifically at how Dico can be made aware of and understand the cognitive burden imposed on a person while driving a car. As well as whether the burden can be attributed to the driving task as such or something else, like the driver’s interaction with a dialogue system.

‘The theory I propose is that it should be possible to interact with a dialogue system as if it were a passenger in your car who is able to see what you see and therefore can take external factors into account when communicating. Such as keeping quiet if heavy traffic makes the driver notably stressed and having a good feel for when it is a good time to talk and give instructions.’

The current systems are unaware of the traffic situation and will keep talking regardless of how ready the driver is to listen. Navigation directions are blurted out with a certain frequency but should perhaps instead be given when the driver actually needs the information, which can vary depending on both traffic and the driver.

‘When driving a car, you shouldn’t have to focus on anything but the actual driving task,’ says Villing, who often turns off the sound of the navigation system in her own car because she feels it can be distracting.
‘I would like to do the opposite, turn off the screen and only listen to the sound, if the interaction feels natural and the information is given when I’m ready to listen.’

Villings hopes that her study will help improve the voice control in cars by making it more intuitive and safer to use.
‘So that drivers will want to use the system and feel that it helps them, instead of forcing them to push buttons and look at a screen. This type of safety-oriented system would lead to fewer accidents,’ says Villing.

Im Focus: Designing Architecture with Solar Building Envelopes

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.

As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...

Im Focus: How to inflate a hardened concrete shell with a weight of 80 t

At TU Wien, an alternative for resource intensive formwork for the construction of concrete domes was developed. It is now used in a test dome for the Austrian Federal Railways Infrastructure (ÖBB Infrastruktur).

Concrete shells are efficient structures, but not very resource efficient. The formwork for the construction of concrete domes alone requires a high amount of...

Im Focus: Bacterial Pac Man molecule snaps at sugar

Many pathogens use certain sugar compounds from their host to help conceal themselves against the immune system. Scientists at the University of Bonn have now, in cooperation with researchers at the University of York in the United Kingdom, analyzed the dynamics of a bacterial molecule that is involved in this process. They demonstrate that the protein grabs onto the sugar molecule with a Pac Man-like chewing motion and holds it until it can be used. Their results could help design therapeutics that could make the protein poorer at grabbing and holding and hence compromise the pathogen in the host. The study has now been published in “Biophysical Journal”.

The cells of the mouth, nose and intestinal mucosa produce large quantities of a chemical called sialic acid. Many bacteria possess a special transport system...
