Web design - Touch and interactions
Ensure that the user keeps control over interactions, particularly tactile ones
Offer an alternative to complex gestures #
Target: everyone in particular, people with motor or visual disability and mobility.
When during design and development.
For each complex gestural interaction, an alternative must be available (for example a non-gestural or simplified alternative).
Similarly for interactions requiring a change of orientation of the screen (tilting, rotation, shaking ...).
Complex gesture: any multi-pointer gesture (requiring several fingers), and / or path-bases gesture.
Simplified gesture: an alternative requiring a single pointer (one finger) without path-based gesture.
Give access to the content regardless of the orientation of the screen #
Target: Everyone in particular, people with motor or visual disability and mobility.
When: during design and development.
Access to the content must not depend on the orientation of the screen (portrait and landscape) unless a specific display orientation is essential (e.g. serious game).
