To create an accessible user interface, apply the following guidelines:
· Avoid using fixed font sizes and small font sizes.
· Enable accessibility options such as font size and idle time settings.
· Ensure that the user interface elements are clearly visible in low light.
· Ensure effective and easy-to-read color combinations.
· Group related objects on the screen.
· Ensure that the user interface is predictable. For example, pressing the HOME hardware button should always display the Home screen.
· For Windows Mobile-based Pocket PCs, ensure that the tap region and size of the user interface element are ergonomic.
On Windows Mobile-based Pocket PCs, the size of the user interface elements should be optimized for a touch screen. The following table lists the optimal sizes for user interface elements on a .24 dot pitch display, depending on whether a stylus or finger is used to interact with user interface elements.
Note A user might have difficulty accurately interacting with user interface elements, due to a disparity between the location of a target on the touch screen and the location of the underlying pixels when the display is viewed at an angle.
On Windows Mobile-based Smartphones, consider the following ergonomic guidelines when you design an application user interface:
· Use the same soft key for similar menus and commands.
· Use the same soft key for sequential commands.
· Avoid using fixed font sizes and small font sizes.
· Enable accessibility options such as font size and idle time settings.
· Ensure that the user interface elements are clearly visible in low light.
· Ensure effective and easy-to-read color combinations.
· Group related objects on the screen.
· Ensure that the user interface is predictable. For example, pressing the HOME hardware button should always display the Home screen.
· For Windows Mobile-based Pocket PCs, ensure that the tap region and size of the user interface element are ergonomic.
On Windows Mobile-based Pocket PCs, the size of the user interface elements should be optimized for a touch screen. The following table lists the optimal sizes for user interface elements on a .24 dot pitch display, depending on whether a stylus or finger is used to interact with user interface elements.
Method of interaction | User interface element size |
Stylus | 5.04mm or 21 x 21 pixels |
Finger | 9.12mm or 38 x 38 pixels |
On Windows Mobile-based Smartphones, consider the following ergonomic guidelines when you design an application user interface:
· Use the same soft key for similar menus and commands.
