Use of Computers

1980s -  people started using PCs on their desk

1990s -  3/4 computers were being used at once when people were surfing the web

- One to look at the web

- One to retreive the web page

- And a couple more to pass information over the internet

Today - probably use 20 or more simultaneously without even noticing (home, school, town, a car)

The Healthcare Robot

Mabu, the healthcare robot, was introduced 

Mabu sits on the owner’s bedside table as a “personal healthcare companion”

It is intended for patients managing chronic diseases

The robot talks to patients and reminds them to take their medication

When Mabu was collected from patients after trials, many objected: “She’s like a member of the family”
