"Optical sensors and touch will be the next big things," Tero Ojanpera, Chief Technology Officer, Nokia, has been reported by Reuters as saying. "I believe there will be a lot of innovation around these."
Touchscreens are starting to appear in growing numbers of mobile devices, from the forthcoming iPhone to the Prada Phone by LG , and has been implemented by Sony Ericsson on several Symbian UIQ-based devices. Nokia has yet to introduce a mainstream mobile phone using touchscreen technology.
Optical sensors can sense movements of a device and translate these into activating a function. Sony Ericsson introduced similar "Shake" movement-activated technology with its W910i Walkman phone , announced last week. Users can change music tracks simply by shaking the phone in a particular direction.
Ojanpera's comments came in Singapore, where he was speaking ahead of the CommunicAsia telecoms exhibition. Nokia today announced three new mid-range handsets, although none featured touchscreen or optical sensor technology.
