Touch App Design Fundamentals

Clean layout

Touch is direct but imprecise

Be consistent

Performance

Touch Friendly

Control targets >= 23x23 pixelsGestures supported through mouse and keyboardNot dependent on hoverControls support Microsoft Active Accessibility (MSAA) for assistive technologies

Touch Enabled

Frequent controls >= 40x40 pixelsRelevant gestures are supported with effect at the point of contactHighly interactive smooth, responsive visual feedback while panning, zooming, and rotating

Touch Optimized

Frequent Tasks Directly on UIImmersive touch experienceReal-world physical feedback (momentum and friction)Handle inaccuracy with touching and draggingReduce the need for heavy text input or precise selection

Touch Considerations

Screen RotationText input without a keyboardHigh DPIMouse and Keyboard supportPerformance
