The Traccia mobile phone concept is designed by Andrea Ponti. Traccia is a phone that’s held as a pen, it recognizes hand movements and converts the same into commands. This concept would probably make an ideal phone for someone who hates typing on a touchscreen or physical keypad, possibly because writing comes easier to them. An embedded optical sensor (like optical mouse laser) located at the end of the stick (phone) detects the traces of what is being written and a software then converts them into text, commands and functions.
It draw invisible lines to access the contacts and menu functions with three buttons on the side for navigation make the stick phone all the more luring. Like all phones now, the Traccia too gets a camera that’s positioned in the center of the arc under the display. Traccia built in polycarbonate is an alternative way to create natural interaction between people and machines.
