VTT introduces unique, human voice-based guidance system for mobile phones


Route directions prove particularly useful for the visually impaired

VTT Technical Research Centre of Finland has developed a unique guidance system for mobile phones, directed and directing by voice. The system provides relief for the everyday life of the visually impaired, in particular for their use of public transportation, but is also suitable for guiding consumers with normal eyesight and people travelling a lot in their work.

The benefit of the guidance system developed by VTT is the introduction of a voice interface for a normal mobile phone. The system is of particular help when using public transportation, but it also contains a great number of other functions and data services.

The guidance system is constantly in touch with public and real time databases: bus, train and tram routes and schedules, information about roadworks, news and weather services, as well as other information useful for the visually impaired. In addition to planning your trip, the system is capable of guiding you to the bus/train/tram stop, informing you of the arrival of the vehicle and telling you where to get off, as well as guiding your path from the starting point to your destination. With the help of satellite positioning, a visually impaired person can also store walking routes that have already been tested and proven good, with precision of within a few metres. The system is not a replacement for the white cane or the guide dog, but serves as a complement and opens up new possibilities for the visually impaired.

This guidance system, developed by VTT, is currently undergoing a test run. The system can already utilise the walking and public transportation routes of the road works database of the city of Helsinki’s construction office. Useful information is also contributed by e.g. train schedules and real time data on domestic flight arrivals and departures.

The voice-based service, which utilises positioning, will become useful also for other parties in the future: companies, associations and individual consumers. Voice-guided queries while on the run have proved easy to use also for the seeing consumer.

Technically, the voice interface of VTT’s guidance system is based on voice synthesis carried out in the mobile phone, and an analysis and identification of speech made in the server computer. Voice recognition is independent of the speaker. The system server utilises textual data available on the Internet when making data searches, and also conducts searches from various databases. Results are sent to the user’s mobile phone. The voice interface is currently available only in Finnish.

Im Focus: Etching Microstructures with Lasers

Ultrafast lasers have introduced new possibilities in engraving ultrafine structures, and scientists are now also investigating how to use them to etch microstructures into thin glass. There are possible applications in analytics (lab on a chip) and especially in electronics and the consumer sector, where great interest has been shown.

This new method was born of a surprising phenomenon: irradiating glass in a particular way with an ultrafast laser has the effect of making the glass up to a...

Terahertz excitation of selected crystal vibrations leads to an effective magnetic field that drives coherent spin motion

Controlling functional properties by light is one of the grand goals in modern condensed matter physics and materials science. A new study now demonstrates how...

Im Focus: New 3-D wiring technique brings scalable quantum computers closer to reality

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.

"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...

Im Focus: Scientists develop a semiconductor nanocomposite material that moves in response to light

In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.

A research team at Worcester Polytechnic Institute (WPI) has developed a revolutionary, light-activated semiconductor nanocomposite material that can be used...

Im Focus: Diamonds aren't forever: Sandia, Harvard team create first quantum computer bridge

By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.

"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
