This document discusses how technology can impact tasks in different ways, including allowing for the creation of new tasks, acting as a direct substitute for existing tools with functional improvements, acting as a substitute with no functional change, and not being used at all. It provides examples of how Google Earth has redefined tasks like locating and measuring distances between places, enhanced research abilities through added layers and functions, and enabled the creation of new tasks like online guided tours.

1. REDEFINITION
Technology allows for the
creation of new tasks,
previously inconceivable.
A print atlas is used to
locate a place.
Google Earth is used to
locate a place.
Google Earth rulers are
used to measure the
distance between two
places.
Google Earth layers such
as panoramio and 360
cities are used to
research locations.
A narrated Google Earth
guided tour is created
and shared online.
ENHANCEMENTTRANSFORMATION
modification

significant task redesign.
Augmentation
Technology acts as direct tool
substitute, with functional
improvement.
SUBSTITUTION
Technology acts as a direct
tool substitute, with no
functional change.
non-use
