Responsive guidelines

Description

Verint applications are required to dynamically respond to the user’s screen size, type, and orientation, ensuring the interface is always clear and accessible.

^ Replace graphic with a Verint app. Should mobile be included?

Supported devices

Sizes

All Verint applications must be usable on devices from a large desktop size (1920 px width) down to the common tablet size (960 px width).

Designs for smaller screens, including mobile devices, are not currently defined in LUX. However, responsive design down to this size is still encouraged.

Where applications need to support screens not currently covered by LUX, contact the UX team for guidance.

Touch devices

Verint applications should support touch devices.

Use tap-and-hold as an alternative access method for components which usually rely on hover, such as Tooltips.
Allow a drag interaction for Scroll.
Increase target areas by enlarging buttons and the space between them, e.g. in Toolbars. Minimum target size recommendations?
Lock the orientation (horizontal) on tablets.

Other access methods

For other interaction methods, such as keyboard and screen readers, see Accessibility.

Approaches

Responsive design is fluid, adapting to the screen size during use.
Adaptive design selects a suitable layout on initial load, but does not respond if the window size later changes.

Verint recommends using a responsive design approach, as it is more dynamic and offers the most consistent user experience.

Adaptive design may be used for mobile screens below 960 px, where necessary.

Layout

Breakpoints should be used to control LUX layouts.

~~Material UI~~ ~~uses these common breakpoints:~~

~~extra-small: 0-600 px~~
~~small: 601 - 960 px~~
~~medium: 961 - 1280 px~~
~~large: 1281 - 1920 px~~
~~extra-large: 1921 px and larger~~

Where there is not enough space to display the full layout, the main workspace should be prioritised. Other areas within the layout may be collapsed or minimised, including the left and right panes.

Containers should respond to any element which can influence its available space, including collapsible panels as well as screen size.

For further guidance and examples of Verint applications at different screen sizes, see Layouts.

Patterns & Components

Each relevant LUX pattern or component has its own responsive guidelines.

For fixed-width elements, such as the Filter Pane and Details Panel, the size is not responsive but features such as pinning and expansion may behave differently at different widths.

Where possible, use vector graphics such as SVGs and font icons, as they are more responsive.

Text sizing should also be responsive, where relevant.

Transitions

Do we need to say anything about acceptable delays when dynamically changing screen width?

Best practices

Where space is limited, it is acceptable to remove auxiliary functionality, but this should be avoided where possible. ??
Creating designs for mobile first and then scaling them up to suit larger screens (a ‘mobile-first’ approach) can make design and implementation easier.
