Window-sized touch screens make shops and streets interactive

Talking, touch-screen bus shelters are scheduled to arrive on Paris and Brussels streets next year. Made of ordinary glass, they will show or speak information at a tap or a word - without using microphones or loudspeakers vulnerable to vandals.

Timetables, maps, weather forecasts, emergency services and audible advertisements could all be at pedestrians’ fingertips, says inventor Jean-Pierre Nikolovski of Intelligent Vibrations in Paris. "It’s a novelty and a tool," he says. Nikolovski hopes that his giant touch-screens will also transform window-shopping into an interactive experience.

"It is pretty amazing", says Chris Matthews of technology-development company CVI Products in Coventry, UK, who is starting to sell the screens. Expanding other types of touch-screen can be expensive or fragile using current display technologies, Matthews explains. Information points, for example, often have screens coated with a thin layer that stores electrical charge, which is altered by a fingertip touch.

Instead, Nikolovski transforms standard glass into an interactive window via its vibrations. [Tapping the screen creates a circle of vibrations, like the ripples in a pool. These travel through the glass to sensitive detectors at each corner that calculate where the screen was tapped. "We can handle giant surfaces," says Nikolovski. Linked to customized software,  a tap can summon videos on a TV behind the window or activate Internet hotlinks projected onto the glass. Speaking into the glass creates sound vibrations that detectors can also locate and record, claims Nikolovski, allowing passers-by to log a message or opinion.] Recently he has added a talkback feature – electrical vibrations can be transferred to the glass so it behaves like a giant loudspeaker.

But Nikolovski is already in negotiations about the bus stops with French and Belgian manufacturers. "You could listen to the radio while leaning against bus-shelter glass," he says.

Table-top jukeboxes and coffee tables with in-built video conferencing are also on Nikolovski’s to-do list. But his dream application is a multiftinctional restaurant table, offering music and recipes to accompany your snack. "While you have a French meal, a travel agency could organize your trip to France," he says.
