Navigatr- Dual screen application

Dual Screen applications provide a new user experience taking advantage of two displays. This all happens using Android for external devices (Android 4.2.2 and above) and MHL technology. MHL stands for Mobile High-Definition Link and is a technology found in many devices, displays and accessories today. MHL enabled smartphones and tablets connect to HD displays, delivering crystal-clear HD content and immersive surround sound, while simultaneously charging the phone. It's the Magic in the Middle. The MHL ecosystem has continued to grow with an installed base of hundreds of millions of products from many of the world’s leading consumer and mobile device companies. One of the most important applications of this technology is in MHL supported presentations. When the presentation is started, it goes live on one of the display screens like projector which is connected via a MHL cable while on the other display screen the options like time limit for an individual slide, total time limit for the entire presentation. In addition to this the background color will change according to time. It will become orange for 20sec, red for 10sec and so on. Additional features like sound system like a single buzzer for 20 seconds, double buzzer for last 10 seconds and so on can be kept. Since this is all based on industry standards; the number of compatible devices is growing very rapidly.
