Beacons are being used in a project by a London startup and the Royal London Society for Blind People to help visually impaired users navigate public transport systems through audio notifications. Ridesharing services like Uber and Lyft are promoting options like UberPool and Lyft Line to allow passengers traveling to similar destinations to share rides, reducing individual costs compared to owning a private vehicle. A connected water bottle band called The Hug aims to notify users if they become dehydrated, raising questions about whether connected devices should replace personal responsibility for health and if such a hydration monitoring device is actually necessary.
