Existing method analysis现有方案分析

A scenario-based comparison of how well current assistive technologies support fast, two-way communication in noisy night markets.基于夜市场景，对比现有辅助技术支持快速、双向沟通的能力。

Method Type How it works Night-market assessment Fit
Cochlear implant
 Medical implant Bypasses damaged parts of the inner ear and directly stimulates the auditory nerve.
+Can provide direct access to sound for suitable users.
−Requires surgery and professional care; costly; outcomes vary; not designed around vendor–customer transactions.
 Low
Hearing aid
 Assistive wearable Amplifies environmental sounds and delivers them to the ear canal.
+Portable, familiar and widely available.
−May amplify background noise with speech; effectiveness varies; communication still depends on spoken language.
 Low–medium
Smart caption glasses
 Digital assistive device Uses microphones and speech recognition to display real-time captions or visual prompts.
+Hands-free and visually accessible.
−Costly and visually conspicuous; recognition can decline in noise; primarily supports one-way information delivery.
 Medium
Design opportunity

Current solutions improve access to sound or speech, but few support visible, hands-free and two-way communication within a vendor’s workflow.
