Product: Samsung SCH-S310 movement recognition phone Price: Not available Pros: Another innovative solution to entering text without a keypad Cons: If awkwardly used, something could be lost in electronic translation After the success of Shaolin Soccer and Kung Fu Hustle, here's a suggestion for a new movie that acclaimed actor-director Stephen Chow Sing-chi might consider: combine martial arts with a motion-sensitive mobile phone. It's an idea whose time has probably come. Last week Samsung Electronics unveiled its SCH-S310 three-dimensional movement recognition mobile phone. The new handset, a CDMA model which will be released in Korea this March, uses motion recognition technology as a unique user interface. In the examples Samsung demonstrated in Seoul, a user can 'write' the number three in the air. The mobile phone can read this movement and then dial three. Shaking the phone twice will conclude a call or delete spam messages. The user can draw an O or X in the air with the phone, which will recognise it and respond with a voice message 'yes' or 'no'. With the music performance function, the phone will begin to play music after it is shaken by the user. The sensors in the phone identify the movement and adjust the beat accordingly. Move the phone sharply to the right and the selection on the MP3 play function will move to the next tune on the list. Move it to the left, and the selection will back up a number. The 'motion beat box' function enables the user to select a particular sound from the menu such as drum, tambourine, scratch or clap. Games will be played by moving the phone up, down, right or left, instead of pressing buttons. The phone will also be able to sense changes in body movement and provide advice on dieting or other health tips. Imagine Chow recreating those functions in choreographed fights or a series of stunts in a movie. There could be some hilarious, slapstick moments worthy of film if dozens of users of 3D motion-recognition phones in a crowded MTR train started making or answering calls all at once. The SCH-S310 phone's 3D movement recognition technology was a joint project between Samsung Electronics and the Samsung Advanced Institute of Technology. The project has resulted in applications for 22 domestic and foreign patents, while 14 technical papers have been presented to a number of leading academic societies.
