Table 26 Comparative analysis of module latency and safety–critical suitability.
Module | Average latency | Primary use case | Suitability for safety–critical tasks | Notes/Limitations |
|---|---|---|---|---|
Face Recognition | < 1 s | Recognizing known individuals | High | Provides immediate auditory feedback for social interactions |
Image Captioning | 4.5 s | Scene comprehension (static or semi-static environments) | Low | Delay is boundary-boundary for dynamic scenarios; not suitable for rapid decision-making, e.g., street crossing |
Online News Reading | 2–3 s per article | Information access | Not applicable | Intended for structured content consumption, offline or semi-static use |
Overall System Responsiveness | Varies with task | Multi-modal assistive support | Partial | Critical tasks should rely on low-latency modules; longer-latency modules provide supplementary contextual information |
