Acoustic user interface creates cheaper touchscreens


Touchscreen phones have become hugely popular and have dramatically improved the experience of browsing menus and the internet. To bring touchscreen technology to more users, InputDynamics has a simple and cost-effective solution that uses the acoustic signal produced by tapping on the screen or handset to create the effect of a touchscreen. Its technology allows cheaper production of touchscreen phones and enables older phones to be retrofitted with a touchscreen.

InputDynamics' novel approach also takes touch functionality to a new level by enabling the entire handset to be touch sensitive, not just the screen. A tap or swipe anywhere on the phone can be recognised, producing new ways for users to interact with their phone. This frees user-interface designers from the constraints of conventional screens and keypads. Smartphones too will benefit from the input functionality being extended to include all of the handset casework.

Giovanni Bisutti, the Cambridge-based entrepreneur behind InputDynamics' technology, says, “The success of the iPhone proved the desire for more intuitive user-interfaces. But superior navigation ability and efficient interaction with multimedia applications need not be limited to the high end of the market. Many people are restricted in their use of internet and apps because they don't have touchscreen phones, but our technology can make touchscreen functionality available to all feature phones. We are also very excited about the opportunity to make whole handsets touch sensitive.”

Tapping allows the user to select numbers, icons, commands, hyperlinks, photos and other software. A swipe or scratch with the finger enables the user to scroll, zoom or pan, making browsing a simpler and more intuitive experience.The phone's existing microphone is used and so InputDynamics' solution to creating touchscreens is entirely software based. This has two major advantages: they can make a touchscreen phone without the need for expensive hardware, and the software can be retrofitted to existing phones.
