It's fairly rare for most people to leave the house without a phone in hand, which is causing a problem for crosswalk safety. Knowing that today's youth are easily distracted by chat messengers and social media, mobile network provider O2 developed 'Watch Out!' a beacon that is set up near crosswalks to alert phone users of oncoming traffic.
To make use of Watch Out, the appropriate app must be installed and a phone's Bluetooth feature must be enabled. From there, when a person approaches a dangerous location, they are sent a signal that immediately blocks all smartphone activity, helping to bring a pedestrian's full attention back to the crossing in front of them. Although the success of this app relies on installation, activation and proximity to beacons, it still has the potential to be life-saving.
