"Warm Breeze Whistle" is a simple sos call system on a mobile phone, by combining the analogue gesture and digital device.
When you're in case of danger, blow your smart phone. After sensing heat of your breath, your mobile phone will make a big sound like a whistle.
And it will send out an emergency call automatically, transmit your location to the police without dialing.

This digital system can urge others to pay more attention to your emergency and police to help you with dispatch. It can be pre-programmed on a mobile phone with air temperature sensors and connected to local police service.
