UI Design Guideline - Edge screen panels
1. Basic interactions
Users can open panels through the handle while the screen is turned on. The panels are looped by the order that the users have set. When the users tap the contents in the panel, the connected link is shown. To close the panel, users click outside of the panel area.
Users can edit each panel through the Edge panel settings. Edit buttons are provided for each panel. The buttons show the corresponding setting screen of the panels.
2. Design principles
The Edge UX allows users to quickly access frequently used applications and information through panels.
Panels can always be called regardless of the application currently opened. Panels can be used independently. The items are displayed in the order that the users have set.
Quick access type
This is a Bridge. It is the access path of frequently used tasks or applications. It allows users to access tasks from any screen.
Quick view type
This is an Overlay widget. It allows users to access and check information at any time without having to open applications.
Quick control type
This is a Quick controller. It allows users to control tasks without having to open applications.
3. UI overview
Panels provide contents that users have to check. When a panel is opened, the previous screen dims and the user cannot interact with it.
3-1. Panel title
The title of the currently shown panel is displayed. It can display text or an image. If the panel is connected to an application, it can be opened by tapping the title.
3-2. Contents area
Contents can be arranged freely in the 138 dp according to content type. By default, the orientation of text and images is portrait. When the contents exceed the content screen, users can scroll up and down. To finish a task immediately through panels, we do not recommend using additional panel depth.
3-3. Panel contents link
Predefined actions are provided.
3-4. Sub information area
Whenever there is other meaningful or additional information for a panel, ‘Sub Information’ is displayed on the sub-area. Contents of ‘Sub information’ comprises a summary, recommendation, and information related to the main information, which is always useful to user. The sub area consists of the ‘Header’ and ‘Contents'. Because `Sub information` is not required, this area is not displayed whenever there is no `Sub information`.
In consideration of the ‘Panel’ and ‘One handed operation’, the interaction on the `Sub information` section is minimal. Moreover, in order to concentrate on major panel, the hierarchy of the 'Main information' and ‘Sub information’ is distinguished by visual division and amount of information. If there is a large amount of information, it can be scrolled. Examples are shown below.
Help area: Displays general description or instruction about the panel.
Notification area: Displays main information that user should not miss.
Related information area: Displays a summary of the main information or other related information.
Category area: It is used as tab to switch contents of the panel.
3-5. Pull to refresh
Drag down the uppermost area with one hand quickly whenever you want to update or refresh the information of the panel.
4. Design Guidelines
We recommend following these guideline for an effective usage of your panel.
Contains summarized information so that users can identify information at a glance. Items must be converged in the panel to achieve visual balance. Layout should be arranged in such a way that it could be easily checked and accessed within the 550px area.
Sub area should be simpler than the main area.
Panel setting preview
Preview image should be effectively display characteristics and concepts in order for the panel's preview image to be distinguishable. Preview area should be accurate and images should be clear to effectively convey the panel's function.
5. Visual style
We recommend that Edge panels conform to the size and form defined below. Use the following table as a guide to your panel's screen density level.
|Screen width x height(DP)||411 x 869||360 x 760||320 x 676|
|Edge panel width x height(DP)||158 x 778||138 x 681||123 x 605|
Make the layout of the main area like those shown in the following images. It is possible to combine panel layout concepts as you desire.
Choose among the font sizes shown in the following images, with consideration to readability and panel width.
If user selects the step 1 through 3 of the font size under Settings > Display > Font size and style, the default font size is applied.
If user selects step 4, font size is set to 1.1 times bigger than the default size.
If user selects step 5 through step 8, the font size is set to 1.3 times bigger than the default size.
