Layout and auto-hide
Controls appear on tap and fade after a few seconds (Apple, n.d.). Keep play large and centered and controls at touch target sizes (Parhi et al., 2006). Viewers seek around specific segments (Kim et al., 2014), so offer double-tap 10-second seeks and scrub thumbnails.
Fast start and autoplay
Startup delay drives abandonment (Krishnan & Sitaraman, 2013), so show the first frame fast and indicate buffering. Browsers often block autoplay with sound (Chrome for Developers, n.d.); start feeds muted with a clear unmute. Use playsinline on iOS web (MDN, n.d.).
Fullscreen, gestures and captions
Support landscape and keep controls inside the safe area; avoid clashing swipes with system gesture navigation. WCAG 2.2 (W3C, 2023) requires captions (1.2.2), audio control (1.4.2) and pause (2.2.2); add captions via track (MDN, n.d.) with resizable text.
FAQ
- Is autoplay okay?
- For feed previews, start muted with clear sound and stop controls.
- When to hide controls?
