The V603SH mobile phone (manufactured by Sharp of Japan) released by Vodafone KK in mid-February 2005 can be operated by shaking or tilting. With the menu screen displayed, the case can be tilted left-right or up-down, just like rolling a ball on your palm, to move the cursor in four or eight directions. By shaking the case in a preset fashion, the user can open specified menus or launch applications.
One key part of the V603SH is the sensor module, developed jointly by Vodafone and Aichi Steel Corp of Japan. Unlike existing acceleration sensors, it incorporates a geomagnetism sensor for direction information into the same package. Measuring only 5.5 x 5.5 x 1.5mm, the miniature sensor offers improved functionality in the same volume – or in only a few dozen percent more volume – than that occupied by currently used acceleration sensors.
