Recently announced Nokia 5500 Sport phone is Nokia’s first mobile phone to use a 3D motion sensor, creating the new user-experience possibilities. In the Nokia 5500 Sport, software using this feature helps users monitor aspects of their exercise programs, such as number of calories burned, speed, distance covered, and number of steps taken. The technology could also be used to control other applications. For example, slide-presenter software might switch slides when the user moves the phone in a certain way. To help developers create new, motion-sensitive applications, Nokia will soon introduce an SDK for devices with 3D accelerometers. Nokia plans to introduce other phones that use 3D-motion-sensor technology in the near future. Read more – post about 3D motion sensor in Nokia 5500 on Forum Nokia Blogs.
