This document summarizes a study on technology substitution. The study surveyed 101 people about their device and service usage. It found that smartphones, laptops, and desktops were the most commonly used devices. Communication, social networking, and office applications were the most regularly used services. The results also showed differences in device and service usage based on demographics like gender, age, and country of origin. The conclusion recommends considering each target group's unique needs when designing cross-device services and solutions for technology substitution.
3. Technology
Substitution
Our activities are being supported by a
wide range of digital artifacts.
These artifacts can be dynamically
substituted based on the context of the
activity.

4. Goal of Research
Gain an understanding, which artifacts are
being used and continuously substituted
and under which circumstances.

5. Research Questions
Which types of devices people use?
In which circumstances people use their
devices?
Which types of services people use on
their devices?
Which specific features of those
services are used on which devices?

8. Pilot Study
Accidental sampling with 4 respondents
for online and 3 for face-to-face testing.
Insights into completion times and
potential areas of misunderstanding.
Improvements to the list of service
types.

11. Results
101 full responses.
58,4% - male; 41,6% - female.
53,5% - under 26 years old; 46,5% - 26
and older.
9 countries represented, with most
respondents from Estonia and Cape
Verde.

16. Additional Analysis
Based on the collected demographics we
compared:
Men and women
Estonians and Cape Verdeans
People under and above 26
The significance threshold was 10%.
16
17. Device Usage by
Gender
Men use more desktops, tablets, and
Smart TV-s.
Women use more laptops and
smartphones.
17
18. Device Usage by
Country
Estonians use more devices in general
than Cape Verdeans.
The most significant difference is in the
usage of smartphones and Smart TV-s.
18
19. Device Usage by Age
Older people use more devices.
There was an almost 2x difference in
usage of desktops and tablets.

21. Service Usage
Social network usage is skewed more
towards women.
Men prefer to use calendaring, reading,
note-taking, and task management
services.
Estonians use more calendaring, file
sharing, blogging, and task management.
Usage of file sharing, calendaring, and
blogging is skewed towards those above

22. Service Usage on
Devices
22
Men Women Estonians Cape Verdeans Under 26 Over 26
Blogging and task
managements
done most on
tablets, the least
on desktops.
Use laptops the
least across all
services.
Use laptops the
least for reading
and calendaring.
Do not use
smartphones for
calendaring at all.
Service usage is
unevenly
distributed,
especially in case
of file sharing,
calendaring,
reading, and
blogging.
Tablets are
preferred for
reading and
blogging.
In case of file
sharing there is a
preference
towards desktop
usage, whereas
reading is done
more on tablets,
less on laptops.
For file sharing,
calendaring,
reading, blogging,
note-taking, and
task
management,
service usage is
very unevenly
distributed.
Smartphones are
quite commonly
used as well,
while laptops are
used less.
Task
management is
preferred on
mobile devices
instead of the
desktop.
23. Discussion
People want to be up-to-date anytime,
anywhere, and on any device.
Cross-device services and the
possibility to synchronize data put users
on top of things.
Yet survey results also show that there
are differences in all of the analyzed
segments across both device and
service usage.
23
24. Conclusion
Take a close look at unique features of each
target group when designing solutions for
technology substitution.
Understand whether people want to have
access to services across all of their devices,
but are currently not able to, or whether they
prefer to use specific devices for specific
purposes.
Address the implications of designing for
ever-changing software and hardware
configurations.

Editor's Notes
#9: The sample was drawn from the part of the population close to hand. The resulting sample was not representative but sufficient for the purposes of the pilot study.
#10: The sample is based on the judgement of the researcher. Participants are invited to answer an online questionnaire and the sampling minimizes the time needed to contact respondents as well as increases the chances that they will answer the survey. The selection however may be biased and so our generalizations are made only on the level of the sample.
#17: 10% was selected because most resulted differed by either less or significantly more than 10%.
