Elderly patients often struggle to find basic controls like mute or camera toggle during video consultations, leading to awkward moments and consultation delays.
How Apps Solve It
Practo places all essential controls (mute, camera, end call) in a persistent bottom bar with large, clearly labeled buttons that remain visible throughout the call. Apollo 24|7 takes a different approach, using gesture-based controls where tapping the screen reveals controls that auto-hide after 3 seconds to maximize video space. Meanwhile, Tata Health uses a hybrid model with permanent mute/unmute buttons but hides advanced features like screen sharing in a collapsible menu. Practo's approach prioritizes accessibility for older users, while Apollo targets tech-savvy patients who prefer minimal UI. Tata Health attempts to balance both needs but risks confusing users about where specific features are located.
The Design Pattern
This is called the Floating Action Bar pattern - a persistent or semi-persistent control panel that houses primary video call functions. It typically appears at the bottom or top of the screen during active video sessions. When poorly implemented, users panic during emergencies (can't find the end call button), accidentally trigger actions (buttons too close together), or miss important features hidden in submenus.
Why It Matters
Indian users span vastly different tech literacy levels, from urban millennials to rural elderly patients accessing healthcare for the first time. Designers constantly debate whether to prioritize simplicity for first-time users or efficiency for regular users, as telemedicine adoption exploded 10x during COVID-19.
Key Terms
- Persistent Controls: UI elements that remain visible throughout the interaction
- Progressive Disclosure: Revealing advanced features only when needed
- Touch Target: Minimum 44x44px tappable area for accessible button design
- Proximity Grouping: Placing related functions together for intuitive navigation
