Its User interface Is Responsive To 4 Buttons:
1# A Rolling To Select and Pressing to Confirm The Selection ( Like in-car dashboard navigation knob );
2# A Previous, OK, Next 3-in-1 Button, with OK button for Bookmark / Like/ My favourite function;
3# A Return Button To Return to previous menu;
4# A menu button to enter into main page of On-screen-menu;
Consider 3 different Resolutions 1024x768 /1920 x 1080 / 3840x2160 ( start from 1024x768 );
The whole mockup must work via mouse or touch to stimulate the real functions,
Any creative ideas based on draft UI ( to be informed ) will be appreciated.
