Buttons
Should all navigation keys be operable on an app?
Selectable UIs must be controlled by 4-way navigation keys (Up, Down, Left, Right), OK and Back buttons. However, OSD buttons which are working with colored keys (red, green, yellow, blue) do not need to be controlled by 4-way navigation keys.When clicking the Back button in an entry page of the app, where to move on?
Pressing the Back button on the Remote Control in an entry page must display the Home screen, rather than a previous page. For the detailed information, see Back Button.Cursors
Should all screen cursors be operable on an app?
Selectable UIs must be controlled by screen cursors and OK.Selection Effect
When and where do I need to apply the selection effect?
ALL of the objects in your app MUST ALWAYS provide some sort of selection effect with NO EXCEPTION. Unlike touch-enabled devices, taking action on TV requires 2-step user interactions; the user needs to select a UI element on the screen using the pointer or the arrow keys depending on the remote control mode, then press the OK button. Therefore, for better user experience, it is necessary that you apply selection effect (animation, highlight, color or size changes, etc.) to show what element is activated.
