The idea for this app is to help the deaf and hearing impaired with their day-to-day activities. This is done by alerting them for events that normally require you hearing abilities, for example thinks like the doorbell, baby monitor, telephone, fire alarm, etc. etc. The way this works is that the app will receive alert notifications from a signaling gateway to be presented to the application user. App to work together with the Sensa RF Gateway. The RF gateway receive signals from wireless doorbells, smoke-detectors etc. and sends these to the App. The App will alert the user visually, it vibrates according to a unique pattern, plays a sound and it flashes.
