Design and implementation of a hard disk-based entertainment device for managing media contents on the go

We present a design and implementation of a prototype system of the hard disk based portable entertainment device called photo jukebox based on an ARM-based system for managing thousands of personal photo/music collections anywhere you go. This photo jukebox system is designed as a music-centric entertainment player, slideshow player, and digital photo storage with built-in metadata database. In addition, this photo jukebox comes with a host application on computer for managing and synchronizing the contents seamlessly. In addition, based on this system, we have applied for a process of user-centered design. Therefore, the ease of use of its user interface was investigated using the human computer interaction (HCI) methods of heuristic evaluation and usability testing. The user interface was subsequently modified, and a follow-up usability test confirmed improvements to ease of use. These findings demonstrate that HCI methods can and should be used to enhance the usability of handheld-based entertainment hardware. At last, we will explore how we conduct the configurable dynamic power management based on different user profiles to enhance the battery life on such multimedia devices.
