Amaral Carvalho, a children's hospital in Sao Paolo, Brazil, has created a teddy bear that allows kids in isolation for cancer treatment to hear audio messages from family and friends when they squeeze its paw, using messaging service WhatsApp. The "ELO" bears (the name means "link"), created by agency DM9Rio for the hospital's 100th anniversary, were fitted with a device that receives messages, as well as in-built speakers.
Each child has his or her own number, which their relatives can use to communicate with them. The messages are sent to a central office and managed by a hospital employee who sends them to the bears; they can be updated at any time. When the child presses the bear's paw, it releases the stored message. This case study video, initially just posted on the hospital's fan page, has now caught on through Brazilian social media and received over a million views on YouTube.
