January 20, 2005 The rapid evolution of the mobile phone took an interesting turn this week when Samsung demonstrated a movement recognition mobile phone, a new technology that could mark a significant point in the evolution of the man-machine interface. Information input devices for the ever shrinking mobile telephone to date have included several different forms of keypad, touch screen and voice recognition but all have their drawbacks in serving the ever increasing capabilities being packed into new designs by phone designers. In the future, 3D movement recognition technology could become an important user interface and significantly alter mobile phone designs and features. The Samsung SCH-S310 phone's 3D motion recognition user interface can be used in a variety of ways, introducing new features never before seen in a mobile phone. The most significant new feature is the ability to "write" in the air with the phone and have the phone recognise the letters or numbers being written and input those characters, or assign certain movements to functions of the phone, such as "start a new text message" or to control the inbuilt MP3 player or digital camera. This technology will do away with the need for complex keypads on mobile phones, MP3 players, digital cameras and other handheld products. This will particularly effect the way games are played on a mobile phone.
