DataPlay micro-optical engines give single fixed-function devices such as cell phones or digital cameras the capacity to become music players or PDAs by taking advantage of DataPlay’s ability to store hundreds of high resolution images as well as pre-recorded or user-recorded music, digital maps, downloaded attachments, contact lists or other valuable content. Music players will be able to turn into portable video or game players, and new classes of convergent devices will have greater play length, higher resolution, enhanced quality, or more intense and feature rich gaming than what is possible in today's low capacity and limited function devices.
