Many individuals rely on closed captions for accessibility (e.g., hearing-impaired viewers) or preference (e.g., noisy environments, language learners). However, traditional caption systems are often limited in customization and can obstruct content, especially on large screens. Smart TV caption settings are also inconsistent across apps, forcing users to repeatedly adjust preferences. A dedicated, customizable caption display could solve these issues by offering a unified, non-intrusive solution.

The Idea: A Customizable Caption Display

The suggestion is for a discreet, slim display that sits beneath a TV or monitor, showing highly adaptable closed captions. The device could use a low-profile screen (e.g., e-ink or LED) and connect via HDMI or wireless protocols. A companion app would allow users to customize font, size, color, and position, while syncing captions from any video source—broadcasts, streaming apps, or gaming consoles. As an alternative to dedicated hardware, a software-based MVP (like an HDMI passthrough dongle or smart TV app) could first test demand.

Who Benefits and Why?

This could serve several groups:

• Hearing-impaired users: Clearer, adjustable captions that don’t block screen content.
• Language learners: Flexible subtitle positioning for better focus on foreign media.
• General viewers: Improved readability in bright rooms or for caption preferences.

Potential revenue streams include hardware sales, software subscriptions for premium features, or B2B licensing for educational platforms.

How It Compares to Existing Solutions

Unlike built-in TV captions, this would offer consistent customization across all apps. Compared to wearable subtitle glasses, it would be more affordable and less niche. For third-party caption apps, hardware integration could ensure universal compatibility without platform limitations.

An initial software MVP could validate the concept before investing in hardware, while partnerships with TV manufacturers or accessibility advocates might help scale adoption.
