Glow Alarm

What it does

GlowAlarm is a new mobile app developed for the deaf and hard of hearing.It was created to overcome the limitations of existing emergency alert systems. The core of GlowAlarm is to convert information that cannot be heard into visual signals. This allows users with hearing difficulties to quickly respond to emergency situations without missing critical information.

GlowAlarm works in conjunction with smart light bulbs. When an emergency occurs, GlowAlarm immediately controls the connected smart bulbs. The bulbs emit light in various colors and flashing patterns depending on the severity and type of the situation. For example, rapid red flashes signal immediate danger, while slow yellow blinks indicate caution.

GlowAlarm's key function is prioritizing disaster alerts and controlling bulbs accordingly. It distinguishes between non-urgent notifications like heat advisories and life-threatening alerts like earthquake warnings. We use Gemini API, an LLM, to automate this complex analysis and risk classification.

We prioritized recall over precision, as detecting all dangerous situations is crucial in safety-critical contexts. Recall measures how comprehensively actual dangers are detected. Through continuous prompt optimization with the Gemini API, we maximized recall, accepting cases where lower-level incidents might be classified as higher-level ones to ensure optimal safety. This approach minimizes the risk of missing any dangerous situations that could threaten user safety.
