It is very hard for people in wheelchairs to travel alone, as they constantly require help and care from others. However, by simply installing an alarm on the wheelchair, disabled individuals are able to travel on their own. Whenever something is needed, they can simply press the button, and a pre-recorded message will be announced. People within 10 meters of distance can clearly hear the message and rapidly come to help. As a simple example, the disabled personnel can record “excuse me, could you help me” in the device (so that you can travel ‘safe’ but also with ‘sound’, hence the title ‘travel safe and sound’). After pressing the button and getting a willing volunteer to help, the disabled personnel can communicate his needs in better detail. In this way, finally, people with disability can travel alone without the need of intense help and care.
