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

08.06.2004


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: Spider silk key to new bone-fixing composite

University of Connecticut researchers have created a biodegradable composite made of silk fibers that can be used to repair broken load-bearing bones without the complications sometimes presented by other materials.

Repairing major load-bearing bones such as those in the leg can be a long and uncomfortable process.

Im Focus: Writing and deleting magnets with lasers

Study published in the journal ACS Applied Materials & Interfaces is the outcome of an international effort that included teams from Dresden and Berlin in Germany, and the US.

Im Focus: Gamma-ray flashes from plasma filaments

Novel highly efficient and brilliant gamma-ray source: Based on model calculations, physicists of the Max PIanck Institute for Nuclear Physics in Heidelberg propose a novel method for an efficient high-brilliance gamma-ray source. A giant collimated gamma-ray pulse is generated from the interaction of a dense ultra-relativistic electron beam with a thin solid conductor. Energetic gamma-rays are copiously produced as the electron beam splits into filaments while propagating across the conductor. The resulting gamma-ray energy and flux enable novel experiments in nuclear and fundamental physics.

The typical wavelength of light interacting with an object of the microcosm scales with the size of this object. For atoms, this ranges from visible light to...

Im Focus: Basel researchers succeed in cultivating cartilage from stem cells

Stable joint cartilage can be produced from adult stem cells originating from bone marrow. This is made possible by inducing specific molecular processes occurring during embryonic cartilage formation, as researchers from the University and University Hospital of Basel report in the scientific journal PNAS.

Certain mesenchymal stem/stromal cells from the bone marrow of adults are considered extremely promising for skeletal tissue regeneration. These adult stem...
