Ergonomic Tabletop Posture
When the hinge sits between 75° and 115°, the user places the bottom half on a flat surface like a laptop. Viewfinders and video streams rise to eye-level, leaving touch dials stable on the desk.
Simulate how iOS and Android responsive layouts adapt across physical fold angles, tabletop kicks, split multitasking, and hinge seam safe-zones.

A physical fold display introduces a slight crease or dual bezel. Content spanning both displays must never position primary buttons or reading text directly across the spine.
Foldables enable simultaneous app states: drag-and-drop between browser and notes, side-by-side video conferencing, or persistent playback scrubbing while chatting.
Foldable devices utilize twin hall-effect sensors, gyroscopes, and high-precision hinge encoders. When hardware reports an angle between 0° and 360°, the OS Window Manager transitions window scenes between Flat (180°), Tabletop (80°-120°), Tent (260°-300°), and Cover-Screen (0°-10°).
Standard CSS defines @media (horizontal-viewport-segments: 2) and @media (vertical-viewport-segments: 2) alongside environment variables like env(viewport-segment-width) and env(viewport-segment-height) to place components seamlessly on either side of the hinge seam.
A standard smartphone requires a tripod for hands-free selfies, time-lapses, or video calls. A foldable folded at 90° functions as its own built-in tripod. Inverting the UI puts the active image preview on the upright screen and the controls within thumb reach on the flat base.
