Regulatory
Complexity
Strict FDA and global compliance requirements often delay launches. When UI and core device logic are intertwined, a simple visual update can trigger a full system recertification.
Safety & System Instability
Interfaces must be fail-safe. If a host processor becomes overtaxed, the UI must not lag or freeze, especially in life-critical clinical environments.
Legacy System Conflict
Modernizing a proven, validated device often requires adding a modern touchscreen without destabilizing the existing, certified core firmware.
Integration Hurdles
Developing graphics code and hardware drivers from scratch leads to misaligned timelines and resource constraints.
